Product Detail

1.ZLYJ series speed reducer is a transmission part that possesses high precision hard gear surface and thrust  block designed for plastic screw extruder. 

2.The design of product adapts all kinds of norm specified in ZBJ19009-88/it features that gear and axis parts are made of high strength alloy steel.                                       

3.The gear is processes by carburization, quenching and tooth grinding process. 

4.The precision of gear is grade 6 specified in GB1009588.

5.The hardness of gear surface is HRC54~62. At front end of hollow input axis there is large specification thrust bearing that will bear axial thrust force while the screw is working.

6.The complete machine features compact, high in bearing capacity, stable in transmission, low noise, high efficiency, etc

Application Enviroment:

1. The input rotation of prime mover shall be ≤1500rpm 

2. The peripheral speed of gear drive shall be ≤20m/s

3. The working ambient temperature shall be within -40~45°C.Preheat the lubrication oil to above 0°C 

when the ambient temperature is below 0°C. Rotation is available both forwards and backwards. 

However, the high speed  shaft  of some types of reducers has a single way oil pump directing as

defaulted to the output shaft  which rotates clockwise.

Notes: all the extruder gearbox has to trial test running for two hours before deliver to our customers;

All the extruder gearbox has one year warranty.
