Self locking condition of worm wheel and worm gear
Worm and worm gear's self-locking condition, worm gear processing factory tells you about worm and worm's self-locking condition.
The condition of self-locking in worm gear and worm transmission is that the opening helix angle of worm is lower than the friction angle of worm gear and worm contact. That is, x is based on the same basis as things on the inclined plane do not slide, that is to say, y * sin a because the worm spiral angle is usually very small, less than the friction angle, can be self-locking. Usually the single thread worm is self locked, so it can not be reversed. But there are also multi-line worm, it has a large spiral angle, can not self-lock, can be reversed, in a certain situation is to add anti-reversal device.
