We are skilled transmission dealers and offer a broad variety of transmissions, an vital part of several travel systems. Gearboxes can be employed to minimize or boost pace, increase torque, reverse or adjust the path of a generate shaft. Gearboxes are also identified as gear drives, speed reducers, equipment motors, pace reducers and gear reducers.
The expression “gearbox” is utilised to refer to any device that connects a motor to a device and consists of a sequence of gears, also known as a gear established. It receives the primary input velocity from the motor and modifications it to a diverse output speed making use of its gears. Various kinds and combos of gears serve specific reasons. The sorts of gears located in gearboxes consist of spur gears, bevel gears, helical gears, helical gears and worm gears. The overall performance effectiveness of a gearbox is represented by the gearbox ratio, which is the ratio of the speed of the input source to the pace of the output resource

Item Description

Product Description

>Introduction
ZLYJ sequence Reduction Gearbox (pace reducer) is a transmission component for most one screw extrusion line, wihch also possesses substantial precision tough equipment area and thrust block created. Made with standard ZBJ19009-88, it combines effectively with most of devices from different suppliers. Also the gear and axis parts are produced of high energy alloy metal with surface area hardness HRC54~sixty two. In the entrance end of hollow enter axis there is huge specification thrust bearing that will bear axial thrust drive even though the screw is functioning
 

>Applied Circumstance
1. All variety of extrusion & blowing equipment
2. High speed shaft rotation Velocity <1500RPM
3. Operating Environment Temp. -forty~45°C, with temperature underneath 0°C, must pre-warmth lubrication oil to above 0°C
 

>Major Specialized Index
1. Output Speed: sixteen-100 RPM
two. Output Torque: Max.4300 Nm
three. Motor Electricity: 5.5-two hundred Kw
 

>Selection of Gearbox
one. Choose speed ratio
e.g. enter pace n1=1000rpm, output pace n2=70rpm, ratio i=n1/n2=14.28, ought to choose ratio fourteen
two. Select product variety in accordance to input electrical power
e.g. enter electrical power P=26kw, right after examining kind, 29kw>26kw, most ecomonic ought to be ZLYJ200
three. Decide on assemble sort
as for each true use, pick horizontal or vertical sort
4. Compute axial thrust Fa=π*Ds²*Ps/(4*one thousand)
e.g. Screw diameter Ds=75mm, Screw pressure Ps=26MPa
Fa=π*Ds²*Ps/(4*1000)=114.8kN
187kN>114.8kN, ZLYJ200 can bear the axial thrust and financial to choose
five. Validate link measurement
six. Validate CZPT variety

Gearboxes are mechanical gadgets that assist travel systems preserve optimum pace and torque for purposes. Also known as gearboxes and equipment drives, they lessen the rotational pace of the enter shaft by a certain percentage and enhance the power delivered to the output shaft by the very same share. Ratio multipliers increase the deceleration and torque supplied by the reducer by a particular ratio and are ideal for parallel installations. Mounting bases, torque arms and flange couplings are equipment used with the reducer. They are generally employed in programs in which the reducer is not directly connected to the generate mechanism.
Gearboxes go by many various names, including gear drives, velocity reducers, gear reducers, velocity reducers, and equipment motors. All phrases are employed interchangeably when referring to inline gear reducers. Our inventory includes a wide range of equipment reducers for high pace, higher precision purposes with enter speeds up to 4000 RPM.
