ZLYJ gearbox/gear box for pvc extruder machine reduction gearbox
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.
Applicable Scope:
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.
