1. The worm gear reducer can get a sizable gear ratio, and the bigger output torque is more compact compared to the staggered axle gear mechanism.
2. The two tooth of the worm equipment are in line get in touch with, and the bearing Speed reducer capability is much greater than that of the crossed helical gear mechanism.
3. The worm gear reducer transmission is equivalent to the screw travel, which is a multi-tooth mesh travel, therefore the transmission is steady and the noise is very small.
4. The worm gear reducer has self-locking house. When the lead position of the worm can be smaller than the equivalent friction angle between the meshing teeth, the mechanism has self-locking home, 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 powered by the worm wheel. For instance, in the self-locking worm system used in its large machinery, the reverse self-locking house can serve as a basic safety protection.
5. The worm equipment reducer has high transmitting efficiency and serious wear. On the other hand, the relative sliding quickness is large, causing severe use on the tooth surface area and serious heat generation. In order to dissipate high temperature and reduce wear, materials with better anti-friction and anti-wear properties and good lubrication devices tend to be used, so the cost is high.
6. The axial push of the reducer worm is large, and the anti-lock bearing is normally set up on the worm shaft of our factory.
