Background

A planetary reduction gear is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of a motor to a desired number of revolutions and obtain a large torque. The gear with less teeth on the transmission shaft of the planetary reducer is meshed with the big gear on the output shaft to achieve the purpose of speed reduction. The common speed reducer can also mesh with a plurality of pairs of gears with the same principle to achieve the ideal speed reduction effect, and the ratio of the number of teeth of the big gear and the small gear is the transmission ratio. Most of the existing planetary speed reducers rely on a clamping ring to provide a locking effect so as to reduce the return difference of the speed reducer, and after the clamping ring is abraded, the locking pressure of the clamping ring on a bearing is reduced, so that the return difference of the speed reducer is increased, and the error precision is influenced.
