1. ZSYJ series reduction gearbox 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
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.
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.
