series reduction gearbox is a transmission part
that possesses high precision hard gear surface and
thrust block designed for plastic screw extruder.
-The design of product adapts all kinds of norm specified
in 19009-88/it features that gear and axis parts are
made of high strength alloy steel.
-The gear is processes by carburization, quenching
and tooth grinding process.
-The precision of gear is grade 6 specified in GB1009588.
-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
-the complete machine features compact, high in bearing
capacity, stable in transmission, low noise, high
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.
