Two-stage plane steel ball reducer

Abstract

The invention discloses a two-stage plane steel ball reducer, and relates to the technical field of a movable teeth steel ball transmission device. A first-stage plane steel ball transmission system is arranged on a driving shaft through a first bearing component, and a second-stage plane steel ball transmission system is arranged on an output shaft through a second bearing component. The first-stage plane steel ball transmission system is connected with the second-stage plane steel ball transmission system through an intermediate transmission system. The intermediate transmission system can convert the swing output of the first-stage plane steel ball transmission system to rotary motion and convert the rotary motion to the swing input of the second-stage plane steel ball transmission system. The two-stage plane steel ball reducer has two-stage transmission and a large transmission ratio and has the advantages of a plane steel ball reducer. Moreover, a bearing is adopted to transfer power and can convert high-speed motion to low-speed motion, and the relative sliding between meshing pairs is reduced. Meanwhile, the driving shaft does not mesh directly with movable teeth, and thus the overall transmission efficiency of the reducer is greatly improved.

Description

technical field [0001] The invention relates to the technical field of movable tooth steel ball transmission devices, in particular to a double-stage planar steel ball reducer. Background technique [0002] With the continuous development of movable tooth transmission, many new movable tooth reducers have come out one after another. The invention patent with the application number of 201510629776.4 discloses a movable tooth cam mechanism output through the oscillating disc. By changing the closed groove tooth profile curve of the oscillating disc, It can realize the conversion of uniform speed input into various forms of swing cam output motion, but the high-speed rotation of the driving shaft leads to a great increase in the relative sliding between the meshing pairs, resulting in a decrease in transmission efficiency; the planar steel ball reducer is a representative of movable tooth transmission Unique transmission type, not only small in size, but also because the racewa...

[0002] With the continuous development of movable tooth transmission, many new movable tooth reducers have come out one after another. The invention patent with the application number of 201510629776.4 discloses a movable tooth cam mechanism output through the oscillating disc. By changing the closed groove tooth profile curve of the oscillating disc, It can realize the conversion of uniform speed input into various forms of swing cam output motion, but the high-speed rotation of the driving shaft leads to a great increase in the relative sliding between the meshing pairs, resulting in a decrease in transmission efficiency; the planar steel ball reducer is a representative of movable tooth transmission Unique transmission type, not only small in size, but also because the raceway of the shock wave and the end face of the center wheel is processed in the plane, the manufacturing process is good, but the driving shaft of the existing planar steel ball reducer with high speed is directly meshed with the movable gear, The transmission efficiency is seriously affected, and the transmission of the single-stage planar steel ball reducer is relatively small. Therefore, a double-stage planar steel ball reducer with the advantages of the planar steel ball reducer, high transmission efficiency and large transmission ratio is developed. In order to be applicable to the development needs of more new technologies and new equipment
