1. The worm gear reducer can get a large equipment 
ratio, and the larger output torque is more compact compared to the staggered axle gear system.
2. The two tooth of the worm gear are in line contact, and the bearing capability is much greater than that of the crossed helical equipment mechanism.
3. The worm gear reducer transmission is equivalent to the screw travel, which really is a multi-tooth mesh drive, so the transmission is steady and the sound is very small.
4. The worm equipment reducer has self-locking house. When the lead angle of the worm is usually smaller than the equivalent friction angle between the meshing teeth, the mechanism has self-locking house, and the reverse self-locking could be realized, that is, the worm wheel can only be driven by the worm, and the worm can not be driven by the worm wheel. For instance, in the self-locking worm mechanism used in its large machinery, the reverse self-locking home can serve as a security protection.
5. The worm gear reducer has high transmitting efficiency and severe wear. On the other hand, the Helical Gearboxes relative sliding rate is large, causing serious wear on the tooth surface and serious heat generation. In order to dissipate temperature and reduce wear, components with better anti-friction and anti-wear properties and good lubrication devices tend to be used, therefore the cost is high.
6. The axial push of the reducer worm is normally large, and the anti-lock bearing can be installed on the worm shaft of our factory.
