Product Description


As one of the relatively common reducers in the family of worm gear reducers, it adopts light and rustless aluminum alloy box and is composed of worm gears and worms, featured by compact structure, vast range of ratios, light vibration, low noise, low energy consumption, stable operation, high transmission torque and self-locking under some condition. The product is widely applied to light industry machinery, textile equipment and grain machinery,etc.

Gearbox Material


Housing: die-cast aluminum alloy (Housing size: 025-090); cast iron (Housing size: 110-150)
Shaft: 20Cr, carbonize and quencher heat treatment make the hardness of gear tooth surface up to 56-62 HRC, retain carburization layer’s thickness between 0.3-0.5mm after precise grinding
Worm Wheel: Wearable bronze alloy

Surface Painting For Aluminum Alloy Housing


1. Shot blasting and special antiseptic treatment on the aluminum alloy surface

2. After phosphating, paint with blue or sliver.

For Cast Iron Housing


Before paint with blue or sliver, need paint with red antirust pain first.
