1. The worm equipment reducer can get a sizable gear ratio, and the bigger output torque is smaller sized than the staggered axle gear system.
2. The two teeth of the worm equipment are in line contact, and the bearing capability is much higher than that of the crossed helical gear mechanism.
3. The worm gear reducer transmission is the same as the screw drive, which really is a multi-tooth mesh travel, therefore the transmission is steady and the sound is very small.
4. The worm equipment reducer has self-locking property. When the lead angle of the worm can be smaller compared to the equivalent friction position between the meshing teeth, the mechanism has self-locking real estate, and the reverse self-locking could be realized, that is, the worm steering wheel can only be powered by the worm, and the worm can not be powered by the worm wheel. For example, in the self-locking worm mechanism used in its heavy machinery, the reverse self-locking house can serve as a safety protection.
5. The worm gear reducer has high transmission efficiency and critical wear. On the other hand, the relative sliding velocity is large, causing serious put on on the tooth surface and serious heat generation. To be able to dissipate warmth and reduce wear, components with better anti-friction and Scroll Air Compressors anti-wear properties and great lubrication devices 
tend to be used, so the cost is high.
6. The axial power of the reducer worm can be large, and the anti-lock bearing can be set up on the worm shaft of our factory.
