1. The worm timing pulley equipment reducer can get a huge gear ratio, and the larger output torque is more compact compared to the staggered axle gear mechanism.
2. The two tooth 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 is a multi-tooth mesh drive, therefore the transmission is steady and the sound is very small.
4. The worm gear reducer has self-locking real estate. When the lead position of the worm can be smaller compared to the equivalent friction angle between the meshing teeth, the system has 
self-locking home, and the reverse self-locking could be realized, that is, the worm wheel can only be powered by the worm, and the worm can’t be driven by the worm steering wheel. For instance, in the self-locking worm mechanism used in its large machinery, the reverse self-locking house can serve as a protection protection.
5. The worm equipment reducer has high transmitting efficiency and significant wear. On the other hand, the relative sliding velocity is large, causing severe wear on the tooth surface and serious heat generation. To be able to dissipate temperature and reduce wear, components with better anti-friction and anti-wear properties and great lubrication devices tend to be used, so the cost is high.
6. The axial force of the reducer worm is normally large, and the anti-lock bearing can be set up on the worm shaft of our factory.
