Ball reducer

Abstract

The invention relates to the technical field of reducers, and particularly discloses a ball reducer. The ball reducer comprises a shaft body. The shaft body comprises a mounting part and an eccentric part connected with the mounting part. The eccentric part is provided with a drive disc. The mounting part is provided with an output disc. The output disc comprises an inner ring, an outer ring and a plurality of balls. The mounting part is sleeved with the inner ring. The inner ring is sleeved with the outer ring. The multiple balls are arranged between the inner ring and the outer ring. A hypocycloid ring groove is formed in the side, close to the inner ring, of the drive disc. An epicycloid ring groove is formed in the side, close to the drive disc, of the inner ring. A plurality of roll balls are arranged between the hypocycloid ring groove and the epicycloid ring groove. During actual application, the shaft body of the ball reducer is connected with a motor, the inner ring serves as an output shaft, movement is transferred through rolling of the roll balls, and speed reduction on the motor is achieved; and rolling friction during rolling of the roll balls is smaller than friction during engagement of gears in a traditional gear reducer, the loss is small, and the transmission efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of reducers, and in particular discloses a ball reducer. Background technique [0002] Reducers are used in most mechanical production equipment. Traditional reducers use gear meshing to achieve deceleration. With the advancement of industrial modernization technology, more and more products have realized automated production. In the automated production process , It is necessary to use robots to replace the original manual operations, and each robot needs to use multiple reducers. [0003] Due to the relatively large friction force when the gears mesh in the traditional gear reducer, the loss during transmission is relatively large, and the transmission efficiency is low. Considering that a robot will use multiple reducers, and a complete production line often requires multiple Robots, like this, will cause greater energy consumption.
