Worm gear slewing drive and worm structure is often used to transfer motion and power between two staggered shafts.Worm gear and worm in the middle plane is equivalent to gear and rack, worm and screw shape is similar.

Mechanism Characteristics:

1. Large transmission ratio can be obtained, which is more compact than the staggered helical gear mechanism.

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

3. Worm drive is equivalent to spiral drive, multi-tooth meshing drive, so the drive is stable and has little noise.

4. Self-locking.When the leading Angle of the worm is less than the equivalent friction Angle between the meshing gears, the mechanism has self-locking property, and can realize reverse self-locking, that is, only the worm drives the worm, but not by the worm wheel drives the worm.Such as in the lifting of the use of self-locking worm mechanism, its reverse self-locking can play a role in safety protection.
