Self Lock Features
The worm gear and worm drive have the characteristics of reverse self-locking, that is, only the worm can drive the worm gear, but the worm gear cannot drive the worm to move. When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism has self-locking properties and can achieve reverse self-locking, that is, only the worm can drive the worm wheel, but the worm cannot be driven by the worm wheel. Such as the self-locking worm mechanism used in its heavy machinery, its reverse self-locking can play a role in safety protection.
