Product Features

  SZ series cone double-screw extruder gearbox is a special mechanical drive device designed to match with conical double-screw extruder. The device decelerates and increases the torque of the power from master motor through gearbox before exporting it to the long shaft of distribution box that drives short shaft through a pair of slender cone screw gear with drive ratio of 1:1. Long shaft and short shaft drive short screw at the same angel as screw to extrude high-quality products in the way of different direction and outward turning.

This series gearbox is designed according to the standard of JB / T9050.11999. The gears are made of high strength alloy steel. The gear goes through the process of carburizing quenching heat hardening and gear grinding to achieve the precision of grade 6(GBl0095-88) The whole unit is small volume, high carry capacity, stable drive, low noise and high efficiency.

Malfunction May Occur Reson Method
Noise Variation Gear damaged
Bearing damaged
Check the gear, change the damaged part
Adjust the clearance
Replace the damaged bearing
Loud noise from fixed
position of reducer
Looseness of the fixed parts Use the specified torque to tighten bolts or screws
Replace the damaged bolts or screws

Bearing damaged
Oil pump damaged
Check the oil level, add the oil when it's below the level
Check the time of nearest oil replacement, maybe the oil should be replaced
Check the function of oil pump, will have to be changed 
Check the bearing, maybe changed
Dirty oil in reducer
Oil leak from the shell
Seal in not good Sealed the surface
Found water in engine oil Engine oil produced foam Check the oil whether contain water via reagent glass sample 
Check the engine oil via chemical laboratory, wash and change
Working temperature raise up Oil level is too high
Oil ageing
Bearing damaged
Oil pump damaged
Check the oil level, adjust it accordingly
Check the time of nearest oil replacement, replace engine oil
Check the function of oil pump.
Check the bearing.
