Maintenance of the gearbox of the dual-screw extruder
1. The gear box of the dual-screw extruder should be well-ventilated, and the working environment temperature should be within the range of 5-35 °C.
2. Always check the oil quantity of the gear lubricating oil in the box to ensure that the transmission parts in the box are well lubricated.
3. Pay attention to check the bearing parts of the box frequently. The oil temperature of the oil tank of the transmission box should not exceed 70 ºC during operation.
4. The newly put into use gearbox needs to replace the lubricating oil after 250 hours of operation. The oil change time depends on the state of the oil. It is recommended to replace it after 4000-8000 hours of operation or once a year.
5. The gearbox of the dual-screw extruder needs to be regularly maintained and inspected once a year
Operating Process
1. The gear on the input shaft is driven by the motor and starts to rotate.
2. The rotating input gear meshes with other gears inside the gearbox, transmitting power.
3. Different-sized gears within the gearbox are combined to form a gear train. Through continuous meshing and rotation, the high-speed, low-torque power from the input shaft gradually converts into low-speed, high-torque output.
4. The output shaft is connected to the last gear and transfers the output torque to the load.
5. Gear reduction gearboxes typically include lubrication and cooling systems to ensure smooth operation and prevent overheating and damage.
6. Our extruder gearbox converts high-speed, low-torque power into low-speed, high-torque output by changing the size ratios and meshing arrangements of different gears, achieving the function of speed reduction.
Types of Gearboxes:
Based on customer requirements, gear reduction gearboxes can be classified according to the size of the output shaft, center distance of the output shaft, output speed, and torque. Alternatively, we can provide several commonly used types of gearboxes for customers to choose from.

Common Problems and Troubleshooting for Worm Gearboxes
Worm gearboxes, like any mechanical component, can experience various issues over time. Here are some common problems that may arise and possible troubleshooting steps:
- Overheating: Overheating can occur due to factors such as inadequate lubrication, excessive loads, or high operating temperatures. Check lubrication levels, ensure proper ventilation, and reduce loads if necessary.
- Noise and Vibration: Excessive noise and vibration may result from misalignment, worn gears, or improper meshing. Check for misalignment, inspect gear teeth for wear, and ensure proper gear meshing.
- Leakage: Oil leakage can be caused by damaged seals or gaskets. Inspect seals and gaskets, and replace them if necessary.
- Reduced Efficiency: Efficiency loss can occur due to friction, wear, or misalignment. Regularly monitor gearbox performance, ensure proper lubrication, and address any wear or misalignment issues.
- Backlash: Excessive backlash can affect precision and accuracy. Adjust gear meshing and reduce backlash to improve performance.
- Seizure or Binding: Seizure or binding can result from inadequate lubrication, debris, or misalignment. Clean the gearbox, ensure proper lubrication, and address misalignment issues.
- Worn Gears: Worn gear teeth can lead to poor performance. Regularly inspect gears for signs of wear, and replace worn gears as needed.
- Seal Wear: Seals can wear over time, leading to leakage and contamination. Inspect seals regularly and replace them if necessary.
If you encounter any of these problems, it’s important to address them promptly to prevent further damage and maintain the performance of your worm gearbox. Regular maintenance, proper lubrication, and addressing issues early can help extend the lifespan and reliability of the gearbox.
How to Calculate the Input and Output Speeds of a Worm Gearbox?
Calculating the input and output speeds of a worm gearbox involves understanding the gear ratio and the principles of gear reduction. Here’s how you can calculate these speeds:
- Input Speed: The input speed (N1) is the speed of the driving gear, which is the worm gear in this case. It is usually provided by the manufacturer or can be measured directly.
- Output Speed: The output speed (N2) is the speed of the driven gear, which is the worm wheel. To calculate the output speed, use the formula:
N2 = N1 / (Z1 * i)
Where:
N2 = Output speed (rpm)
N1 = Input speed (rpm)
Z1 = Number of teeth on the worm gear
i = Gear ratio (ratio of the number of teeth on the worm gear to the number of threads on the worm)
It’s important to note that worm gearboxes are designed for gear reduction, which means that the output speed is lower than the input speed. Additionally, the efficiency of the gearbox, friction, and other factors can affect the actual output speed. Calculating the input and output speeds is crucial for understanding the performance and capabilities of the worm gearbox in a specific application.
What is a Worm Gearbox and How Does It Work?
A worm gearbox, also known as a worm gear reducer, is a mechanical device used to transmit rotational motion and torque between non-parallel shafts. It consists of a worm screw and a worm wheel, both of which have helical teeth. The worm screw resembles a threaded cylinder, while the worm wheel is a gear with teeth that mesh with the worm screw.
The working principle of a worm gearbox involves the interaction between the worm screw and the worm wheel. When the worm screw is rotated, its helical teeth engage with the teeth of the worm wheel. As the worm screw rotates, it translates the rotational motion into a perpendicular motion, causing the worm wheel to rotate. This perpendicular motion allows the worm gearbox to achieve a high gear reduction ratio, making it suitable for applications that require significant speed reduction.
One of the key features of a worm gearbox is its ability to provide a high gear reduction ratio in a compact design. However, due to the sliding nature of the meshing teeth, worm gearboxes may exhibit higher friction and lower efficiency compared to other types of gearboxes. Therefore, they are often used in applications where efficiency is not the primary concern but where high torque and speed reduction are essential, such as conveyor systems, elevators, automotive steering systems, and certain industrial machinery.

Self-Locking Properties in a Worm Gearbox
Yes, worm gearboxes exhibit self-locking properties, which can be advantageous in certain applications. Self-locking refers to the ability of a mechanism to prevent the transmission of motion from the output shaft back to the input shaft when the system is at rest. Worm gearboxes inherently possess self-locking properties due to the unique design of the worm gear and worm wheel.
The self-locking behavior arises from the angle of the helix on the worm shaft. In a properly designed worm gearbox, the helix angle of the worm is such that it creates a mechanical advantage that resists reverse motion. When the gearbox is not actively driven, the friction between the worm threads and the worm wheel teeth creates a locking effect.
This self-locking feature makes worm gearboxes particularly useful in applications where holding a load in position without external power is necessary. For instance, they are commonly used in situations where there’s a need to prevent a mechanism from backdriving, such as in conveyor systems, hoists, and jacks.
However, it’s important to note that while self-locking properties can be beneficial, they also introduce some challenges. The high friction between the worm gear and worm wheel during self-locking can lead to higher wear and heat generation. Additionally, the self-locking effect can reduce the efficiency of the gearbox when it’s actively transmitting motion.
When considering the use of a worm gearbox for a specific application, it’s crucial to carefully analyze the balance between self-locking capabilities and other performance factors to ensure optimal operation.
How to Calculate the Efficiency of a Worm Gearbox
Calculating the efficiency of a worm gearbox involves determining the ratio of output power to input power. Efficiency is a measure of how well the gearbox converts input power into useful output power without losses. Here’s how to calculate it:
- Step 1: Measure Input Power: Measure the input power (Pin) using a power meter or other suitable measuring equipment.
- Step 2: Measure Output Power: Measure the output power (Pout) that the gearbox is delivering to the load.
- Step 3: Calculate Efficiency: Calculate the efficiency (η) using the formula: Efficiency (η) = (Output Power / Input Power) * 100%
For example, if the input power is 1000 watts and the output power is 850 watts, the efficiency would be (850 / 1000) * 100% = 85%.
It’s important to note that efficiencies can vary based on factors such as gear design, lubrication, wear, and load conditions. The calculated efficiency provides insight into how effectively the gearbox is converting power, but it’s always a good practice to refer to manufacturer specifications for gearbox efficiency ratings.

What are the Noise Levels Associated with Worm Gearboxes?
The noise levels associated with worm gearboxes can vary depending on several factors, including the design, quality, operating conditions, and maintenance of the gearbox. Here are some key points to consider:
- Design and Quality: Well-designed and high-quality worm gearboxes tend to produce lower noise levels. Factors such as gear tooth profile, precision manufacturing, and proper alignment can contribute to reduced noise.
- Gear Engagement: The way the worm and worm wheel engage and mesh with each other can impact noise levels. Proper tooth contact and alignment can help minimize noise during operation.
- Lubrication: Inadequate or improper lubrication can lead to increased friction and wear, resulting in higher noise levels. Using the recommended lubricant and maintaining proper lubrication levels are important for noise reduction.
- Operating Conditions: Operating the gearbox within its specified load and speed limits can help prevent excessive noise generation. Overloading or operating at high speeds beyond the gearbox’s capabilities can lead to increased noise.
- Backlash: Excessive backlash or play between the gear teeth can lead to impact noise as the teeth engage. Proper backlash adjustment can help mitigate this issue.
- Maintenance: Regular maintenance, including gear inspection, lubrication checks, and addressing any wear or damage, can help keep noise levels in check.
It’s important to note that while worm gearboxes can produce some noise due to the nature of gear meshing, proper design, maintenance, and operation can significantly reduce noise levels. If noise is a concern for your application, consulting with gearbox manufacturers and experts can provide insights into selecting the right gearbox type and implementing measures to minimize noise.
Does a Worm Reducer Require Frequent Maintenance?
Worm reducers generally require less frequent maintenance compared to some other types of gearboxes due to their design and operating characteristics. However, maintenance is still essential to ensure optimal performance and longevity. Here are some key points to consider:
- Lubrication: Proper lubrication is crucial for worm gearboxes. Regularly check the lubricant level and quality to prevent wear and overheating. Lubricant should be changed as recommended by the manufacturer.
- Inspections: Periodically inspect the gearbox for signs of wear, damage, or oil leaks. Check for any unusual noises, vibrations, or changes in performance that could indicate a problem.
- Tightening and Alignment: Check and tighten any loose fasteners and ensure that the gearbox is properly aligned. Misalignment can lead to increased wear and reduced efficiency.
- Seal Maintenance: Inspect and maintain seals to prevent oil leakage and contaminants from entering the gearbox.
- Cleaning: Keep the gearbox clean from debris and contaminants that could affect its performance. Regular cleaning can prevent premature wear and damage.
- Load and Speed: Ensure that the gearbox is operating within its rated load and speed limits. Exceeding these limits can lead to accelerated wear and potential failure.
- Environmental Conditions: Consider the operating environment of the gearbox. Extreme temperatures, humidity, and other factors can impact the gearbox’s performance and longevity.
While worm gearboxes are known for their durability and self-locking feature, neglecting maintenance can lead to premature wear, reduced efficiency, and potential breakdowns. Following the manufacturer’s recommendations for maintenance intervals and procedures is essential to keep the worm reducer in optimal condition.
Preventing Backlash in a Worm Gearbox
Backlash in a worm gearbox can lead to reduced accuracy, positioning errors, and decreased overall efficiency. Here are steps to prevent or minimize backlash:
- High-Quality Components: Use high-quality worm gears and worm wheels with tight manufacturing tolerances. Precision components will help reduce backlash.
- Proper Meshing: Ensure the worm gear and worm wheel are properly aligned and meshed. Improper meshing can lead to increased backlash.
- Preload: Applying a small amount of preload to the worm gear can help reduce backlash. However, excessive preload can increase friction and wear.
- Anti-Backlash Mechanisms: Consider using anti-backlash mechanisms, such as spring-loaded systems or adjustable shims, to compensate for any inherent backlash.
- Lubrication: Proper lubrication can reduce friction and play a role in minimizing backlash. Use a lubricant that provides good film strength and reduces wear.
- Maintenance: Regularly inspect and maintain the gearbox to identify and address any changes in backlash over time.
It’s important to strike a balance between reducing backlash and maintaining smooth operation. Consulting with gearbox experts and following manufacturer guidelines will help you optimize your worm gearbox’s performance while minimizing backlash.

Calculating Gear Ratio in a Worm Reducer
The gear ratio in a worm reducer is determined by the number of teeth on the worm wheel (also known as the worm gear) and the number of threads on the worm shaft. The gear ratio formula for a worm reducer is:
Gear Ratio = Number of Teeth on Worm Wheel / Number of Threads on Worm Shaft
For example, if the worm wheel has 60 teeth and the worm shaft has a single thread, the gear ratio would be 60:1.
It’s important to note that worm reducers have an inherent self-locking property due to the angle of the worm threads. As a result, the gear ratio also affects the mechanical advantage and the system’s ability to resist backdriving.
When calculating the gear ratio, ensure that the worm reducer is properly designed and that the gear ratio aligns with the desired mechanical characteristics for your application. Additionally, consider factors such as efficiency, load capacity, and speed limitations when selecting a gear ratio for a worm reducer.
Materials Used for Worm Gears
Worm gears are manufactured using a variety of materials to meet different application requirements. Some commonly used materials for worm gears include:
- Steel: Steel is a popular choice for worm gears due to its strength, durability, and wear resistance. It can handle heavy loads and is often used in industrial applications.
- Bronze: Bronze offers good lubricity and is commonly used for the worm gear (worm) component. It provides effective wear resistance and works well in applications where quiet operation is essential.
- Cast Iron: Cast iron is known for its high strength and durability. It’s often used for worm gears in applications where shock loads or heavy-duty conditions are expected.
- Aluminum: Aluminum worm gears are lightweight and corrosion-resistant, making them suitable for applications where weight reduction is important.
- Plastic: Some worm gears are made from plastic materials such as nylon or acetal. These materials are often chosen for their self-lubricating properties and quiet operation.
- Composite Materials: Composite materials can offer a combination of properties, such as lightweight construction and corrosion resistance. They can be suitable for specific applications.
The choice of material depends on factors such as the application’s load, speed, operating environment, and required performance characteristics. It’s important to consider these factors when selecting the appropriate material for worm gears to ensure optimal performance and longevity.
How to Select the Right Worm Gearbox for Your Application
Selecting the right worm gearbox for your application involves careful consideration of various factors:
- Load Requirements: Determine the torque and load requirements of your application to ensure the selected gearbox can handle the load without compromising performance.
- Speed Reduction: Calculate the required gear reduction ratio to achieve the desired output speed. Worm gearboxes are known for high reduction ratios.
- Efficiency: Consider the gearbox’s efficiency, as worm gearboxes typically have lower efficiency due to the sliding action. Evaluate whether the efficiency meets your application’s needs.
- Space Constraints: Assess the available space for the gearbox. Worm gearboxes have a compact design, making them suitable for applications with limited space.
- Mounting Options: Determine the mounting orientation and configuration that best suits your application.
- Operating Environment: Consider factors such as temperature, humidity, and exposure to contaminants. Choose a gearbox with appropriate seals and materials to withstand the environment.
- Backlash: Evaluate the acceptable level of backlash in your application. Worm gearboxes may exhibit more backlash compared to other gear types.
- Self-Locking: If self-locking capability is required, confirm that the selected gearbox can prevent reverse motion without the need for external braking mechanisms.
- Maintenance: Consider the maintenance requirements of the gearbox. Some worm gearboxes require periodic lubrication and maintenance to ensure proper functioning.
- Cost: Balance the features and performance of the gearbox with the overall cost to ensure it aligns with your budget.

FAQ
How to Select a Gearbox
When you drive your vehicle, the gearbox provides you with traction and speed. The lower gear provides the most traction, while the higher gear has the most speed. Selecting the right gear for your driving conditions will help you maximize both. The right gearing will vary based on road conditions, load, and speed. Short gearing will accelerate you more quickly, while tall gearing will increase top speed. However, you should understand how to use the gearbox before driving.
Function
The function of the gearbox is to transmit rotational energy to the machine’s drive train. The ratio between input and output torque is the ratio of the torque to the speed of rotation. Gearboxes have many different functions. A gearbox may have multiple functions or one function that is used to drive several other machines. If one gear is not turning, the other will be able to turn the gearbox. This is where the gearbox gets its name.
The pitch-controlled system has an equal number of failure modes as the electrical system, accounting for a large proportion of the longest machine downtime and halt time. The relationship between mechanisms and faults is not easily modeled mathematically. Failure modes of gearboxes are shown in Fig. 3. A gearbox’s true service life is six to eight years. However, a gearbox’s fault detection process must be developed as mature technology is required to reduce the downtime and avoid catastrophic incidents.
A gearbox is a vital piece of machinery. It processes energy produced by an engine to move the machine’s parts. A gearbox’s efficiency depends on how efficiently it transfers energy. The higher the ratio, the more torque is transferred to the wheels. It is a common component of bicycles, cars, and a variety of other devices. Its four major functions include:
In addition to ensuring gearbox reliability, a gearbox’s maintainability should be evaluated in the design phase. Maintainability considerations should be integrated into the gearbox design, such as the type of spare parts available. An appropriate maintenance regime will also determine how often to replace or repair specific parts. A proper maintenance procedure will also ensure that the gearbox is accessible. Whether it is easy to access or difficult to reach, accessibility is essential.
Purpose
A car’s transmission connects the engine to the wheels, allowing a higher-speed crankshaft to provide leverage. High-torque engines are necessary for the vehicle’s starting, acceleration, and meeting road resistance. The gearbox reduces the engine’s speed and provides torque variations at the wheels. The transmission also provides reversing power, making it possible to move the vehicle backwards and forwards.
Gears transmit power from one shaft to another. The size of the gears and number of teeth determine the amount of torque the unit can transmit. A higher gear ratio means more torque, but slower speed. The gearbox’s lever moves the engaging part on the shaft. The lever also slides the gears and synchronizers into place. If the lever slips to the left or right, the engine operates in second gear.
Gearboxes need to be closely monitored to reduce the likelihood of premature failure. Various tests are available to detect defective gear teeth and increase machine reliability. Figure 1.11(a) and (b) show a gearbox with 18 teeth and a 1.5:1 transmission ratio. The input shaft is connected to a sheave and drives a “V” belt. This transmission ratio allows the gearbox to reduce the speed of the motor, while increasing torque and reducing output speed.
When it comes to speed reduction, gear box is the most common method for reducing motor torque. The torque output is directly proportional to the volume of the motor. A small gearbox, for example, can produce as much torque as a large motor with the same output speed. The same holds true for the reverse. There are hybrid drives and in-line gearboxes. Regardless of the type, knowing about the functions of a gearbox will make it easier to choose the right one for your specific application.
Application
When selecting a gearbox, the service factor must be considered. Service factor is the difference between the actual capacity of the gearbox and the value required by the application. Additional requirements for the gearbox may result in premature seal wear or overheating. The service factor should be as low as possible, as it could be the difference between the lifetime of the gearbox and its failure. In some cases, a gearbox’s service factor can be as high as 1.4, which is sufficient for most industrial applications.
China dominates the renewable energy industry, with the largest installed capacity of 1000 gigawatts and more than 2000 terawatt hours of electricity generated each year. The growth in these sectors is expected to increase the demand for gearboxes. For example, in China, wind and hydropower energy production are the major components of wind and solar power plants. The increased installation capacity indicates increased use of gearboxes for these industries. A gearbox that is not suitable for its application will not be functional, which may be detrimental to the production of products in the country.
A gearbox can be mounted in one of four different positions. The first three positions are concentric, parallel, or right angle, and the fourth position is shaft mount. A shaft mount gearbox is typically used in applications where the motor can’t be mounted via a foot. These positions are discussed in more detail below. Choosing the correct gearbox is essential in your business, but remember that a well-designed gearbox will help your bottom line.
The service factor of a gearbox is dependent on the type of load. A high shock load, for example, can cause premature failure of the gear teeth or shaft bearings. In such cases, a higher service factor is required. In other cases, a gearbox that is designed for high shock loads can withstand such loads without deteriorating its performance. Moreover, it will also reduce the cost of maintaining the gearbox over time.
Material
When choosing the material for your gearbox, you must balance the strength, durability, and cost of the design. This article will discuss the different types of materials and their respective applications and power transmission calculations. A variety of alloys are available, each of which offers its own advantages, including improved hardness and wear resistance. The following are some of the common alloys used in gears. The advantage of alloys is their competitive pricing. A gear made from one of these materials is usually stronger than its counterparts.
The carbon content of SPCC prevents the material from hardening like SS. However, thin sheets made from SPCC are often used for gears with lower strength. Because of the low carbon content, SPCC’s surface doesn’t harden as quickly as SS gears do, so soft nitriding is needed to provide hardness. However, if you want a gear that won’t rust, then you should consider SS or FCD.
In addition to cars, gearboxes are also used in the aerospace industry. They are used in space travel and are used in airplane engines. In agriculture, they are used in irrigation, pest and insect control machinery, and plowing machines. They are also used in construction equipment like cranes, bulldozers, and tractors. Gearboxes are also used in the food processing industry, including conveyor systems, kilns, and packaging machinery.
The teeth of the gears in your gearbox are important when it comes to performance. A properly meshing gear will allow the gears to achieve peak performance and withstand torque. Gear teeth are like tiny levers, and effective meshing reduces stress and slippage. A stationary parametric analysis will help you determine the quality of meshing throughout the gearing cycle. This method is often the most accurate way to determine whether your gears are meshing well.
Manufacturing
The global gear market is divided into five key regions, namely, North America, Europe, Asia Pacific, and Latin America. Among these regions, Asia Pacific is expected to generate the largest GDP, owing to rapidly growing energy demand and investments in industrial infrastructure. This region is also home to some of the largest manufacturing bases, and its continuous building of new buildings and homes will support the industry’s growth. In terms of application, gearboxes are used in construction, agricultural machinery, and transportation.
The Industrial Gearbox market is anticipated to expand during the next several years, driven by the rapid growth of the construction industry and business advancements. However, there are several challenges that hamper the growth of the industry. These include the high cost of operations and maintenance of gear units. This report covers the market size of industrial gearboxes globally, as well as their manufacturing technologies. It also includes manufacturer data for the period of 2020-2024. The report also features a discussion of market drivers and restraints.
Global health crisis and decreasing seaborne commerce have moderately adverse effects on the industry. Falling seaborne commerce has created a barrier to investment. The value of international crude oil is expected to cross USD 0 by April 2020, putting an end to new assets development and exploitation. In such a scenario, the global gearbox market will face many challenges. However, the opportunities are huge. So, the market for industrial gearboxes is expected to grow by more than 6% by 2020, thanks to the increasing number of light vehicles sold in the country.
The main shaft of a gearbox, also known as the output shaft, spins at different speeds and transfers torque to an automobile. The output shaft is splined so that a coupler and gear can be connected to it. The counter shaft and primary shaft are supported by bearings, which reduce friction in the spinning element. Another important part of a gearbox is the gears, which vary in tooth count. The number of teeth determines how much torque a gear can transfer. In addition, the gears can glide in any position.

When searching at a reducer vs a gearbox, typically the only big difference is terminology. This is since all reducers are gearboxes. Nevertheless, not all gearboxes are retarders. This may possibly audio complicated, but it is truly very basic. A reducer is a gear established in between the motor and the machine. The function of the reducer is to lessen the rotational pace transferred between these two endpoints. The reducer amplifies and multiplies the torque (input) created by the motor. 2nd, a reducer, as the title suggests, lowers the pace of the enter (output in rpm) so that the output is the proper velocity. The phrase “gearbox” is just a generic phrase utilized for the equipment practice between the motor and the machine. For that reason, all reducers are gearboxes. However, not all gearboxes reduce input velocity. Though uncommon, gearboxes can in fact boost enter speeds. By significantly the most widespread type of gearbox is a retarder, but it would be incorrect to say that all gearboxes are retarders.
Gearboxes can be utilised in different fields of comprehensive processing, agriculture, chemical processing, oil and gasoline, electricity transmission and distribution methods, logistics, warehousing and other industries. Equipment reducers are normally used in which larger torque and/or reduce rotational speeds are essential, or if energy wants to be transmitted at alternating angles, this kind of as in proper-angle motors.
