ZLYJ reduction gearbox screw extruder line

ZLYJ series speed reducer 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 ZBJ19009-88/ 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 GB10095-88. 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. The complete machine features compact, high in bearing capacity, stable in transmission, low noise, high efficiency, etc.

Technical parameters:

1) New structure gearbox, high torque, high speed;

2) Gear is 6 grade which is a high precision. High speed overloading hard-tooth surface. The materials are 20CrNi2MoA or 20CrMnMo, HRC 60/62.

3) The output shaft connect with the Screw shaft in splined sleeve.

4) The imported bearings NSK bearings are used. Integrated thrust bearing assembly is Name Luoyang.

5) The bearing and geared are forced to adopted the Hai Brand 6402 oil-lubrication system.

6) framework oil seal is adopted Brand hansheng from Taiwan.
