1. The worm gear Gearbox reducer can get a sizable gear ratio, and the larger output torque is more compact compared to the staggered axle gear system.
2. The two teeth of the worm equipment are in line contact, and the bearing capacity is much greater than that of the crossed helical gear mechanism.
3. The worm gear reducer transmission is the same as the screw travel, which is a multi-tooth mesh get, therefore the transmission is stable and the sound is very small.
4. The worm gear reducer has self-locking property. When the lead position of the worm is smaller than the equivalent friction position between the meshing teeth, the system has self-locking house, and the reverse self-locking can be 
realized, that’s, the worm wheel can only be powered by the worm, and the worm can not be powered by the worm steering wheel. For example, in the self-locking worm system used in its heavy machinery, the reverse self-locking real estate can serve as a basic safety protection.
5. The worm gear reducer has high transmission efficiency and significant wear. On the other hand, the relative sliding quickness is large, causing severe put on on the tooth surface and serious heat era. To be able to dissipate temperature and reduce wear, components with better anti-friction and anti-wear properties and good lubrication devices are often used, so the cost is high.
6. The axial power of the reducer worm is normally huge, and the anti-lock bearing is certainly set up on the worm shaft of our factory.
