1. The worm gear reducer can get a large gear ratio, and the bigger output torque is smaller sized than the staggered axle gear system.
2. The two teeth of the worm gear are in line get in touch with, and the bearing capacity is much higher than that of the crossed helical gear mechanism.
3. The worm equipment reducer transmission is equivalent to the screw get, which really is a 
multi-tooth mesh drive, so the transmission is steady and the noise is very small.
4. The worm equipment reducer has self-locking property. When the lead position of the worm is normally smaller than the equivalent friction position between the meshing teeth, the mechanism has self-locking house, and the reverse self-locking can be realized, that’s, the worm wheel can only be Electric Motors driven 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 heavy machinery, the reverse self-locking house can serve as a protection protection.
5. The worm gear reducer has high transmitting efficiency and significant wear. However, the relative sliding velocity is large, causing severe use on the tooth surface area and serious heat era. In order to dissipate heat and reduce wear, materials with better anti-friction and anti-wear properties and good lubrication devices are often used, therefore the cost is high.
6. The axial force of the reducer worm is usually huge, and the anti-lock bearing is installed on the worm shaft of our factory.
