1. The worm gear reducer can get a huge gear ratio, and the larger output torque is smaller sized compared to the staggered axle gear mechanism.
2. The two tooth 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 equipment reducer transmission is the same as the screw drive, which is a multi-tooth mesh travel, so the transmission is stable and the sound is very small.
4. The worm gear reducer has self-locking real estate. When the lead angle of the worm is certainly 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 is, the worm wheel can only be driven by the worm, and the worm can’t be powered by the worm wheel. For example, in the self-locking worm mechanism 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 serious wear. On the other hand, the relative sliding acceleration is large, causing serious put on on the tooth surface and serious heat generation. In order to dissipate heat and reduce wear, materials with better anti-friction and anti-wear properties and great lubrication devices tend to be used, so the cost is high.
6. The axial push of the 
reducer worm is normally huge, and the China Pulley anti-lock bearing is usually installed on the worm shaft of our factory.
