gearbox for agricultural machinery extruder extruder gearbox



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

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.

Finished Product & Application:

This gearbox are mainly used in Plastic Extruding Machine, like EPS, PE….

Processing equipment:

We have Niles contour gear grinding machine imported from Germany,OKUMA horizontal machining center

 imported from Japan, gear inspection and test center and three-coordinates measuring machine.
