Rotary speed reducer is a kind of integration of driving power source of full circle rotary reducer transmission mechanism. Use a rotary bearing as transmission follower and adhesion mechanism, efficient allocation of driving power source and the main transmission parts, which have functions of rotary, speed reduction and drive function, with advantages of simple structure, manufacture and maintenance convenient. Rotary drive device can be basically divided into single worm drive rotary drive device and double worm drive rotary drive device


Characteristics of worm gear and worm mechanism:

1. Large transmission ratio, which is more compact than staggered helical gear mechanism

2. The meshing tooth surfaces of the two wheels are in line contact, and its bearing capacity is much higher than that of the staggered helical gear mechanism

3. Worm transmission is equivalent to spiral transmission, which is multi-tooth mesh transmission, so the transmission is stable and the noise is small

4. Self-locking.


Application of rotary drive:

Double worm slewing drive for construction machinery, slewing drive for truck crane, slewing drive for heavy-duty flatbed transport truck, slewing drive for aerial 

work truck drive, rail car slewing drive, dirt suction car slewing drive, rotary claw slewing drive, bridge testing car slewing drive device, rotary drive device, wind 

power yaw rotary drive device, solar energy rotary drive.
