Description

Mechanical Variable Speed Gearbox For Electric Motor Description

Variable-speed gearbox is made up of worm drive gearbox, stepless variator, and ac induction motor, etc. as one of the speed multiplier gearbox manufacturers. SDT variable speed gearbox has a standard modular design and special application in the engineering machine etc.

Characteristics
1. Aluminum alloy housing
2. High-quality bearings prevent leaks, contribute to flexibility in mounting and increase reducer life
3. NEMA and IEC motors inputs
4. Double-lip oil seals
5. O-rings are used to prevent leaks
6. Standard hollow output bore and optional plug-in shafts provide greater flexibility.
7. Automated manufacturing process from an ISO 9001 certified company assures quality, reliable gearing.

The Materials of Variable Speed Gearbox for Electric Motor

 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.
