Problems solved by technology

However, due to the tooth backlash in the output mechanism of the traditional gear transmission with small tooth difference, intermittent and uneven rotation will occur during forward and reverse rotation. Greatly reduced
As a result, large volume, heavy weight, consumables, energy consumption, etc. are insufficient

Abstract

A zero-tooth-difference internal gear pair transmission mechanism comprises a set of zero-tooth-difference internal gear pair [1], an eccentric shaft [2], two end covers [3] and a pressing rivet ferrule [4], wherein the zero-tooth-difference internal gear pair comprises an internal gear (11), a planetary gear elastic deformation ring (12), a zero-tooth-difference gear output shaft (13) and the like. The tooth shape of the internal gear (11) is an involute curve (111); eight semi-cylindrical grooves are uniformly distributed on the periphery of the internal gear, used for mounting and compacting the pressing rivet ferrule and connected with accessories of a related product to be developed; the tooth shape of the planetary gear elastic deformation ring is an involute curve (121), an involute curve (122), an involute curve-fit arc or a linear equidistant curve; the eccentric distance of the eccentric shaft needs to be slightly greater than the central distance between the internal gear and the planetary gear elastic deformation ring; and the zero-tooth-difference internal gear pair transmission mechanism driven by the rotation of the eccentric shaft can drag the zero-tooth-difference gear output shaft to rotate in a speed reduction way according to the transmission ratio of small tooth difference, so as to perform forward and reverse gapless uniform rotation operation.

Description

technical field [0001] The invention relates to an output mechanism in gear transmission with few tooth differences in machinery. It is a zero-tooth-difference internal gear pair transmission mechanism. Due to the tooth side clearance in the output mechanism of the traditional gear transmission with small tooth difference, intermittent and uneven rotation will occur during forward and reverse rotation, its axial length is very long, and the force between the gears is uneven, and the bearing capacity is large reduce. Background technique [0002] As is well known in the prior art, people use a pin connection, an Oldham connection or a zero-tooth-difference gear pair connection as an output mechanism in a gear transmission with a small tooth difference. However, due to the tooth backlash in the output mechanism of the traditional gear transmission with small tooth difference, intermittent and uneven rotation will occur during forward and reverse rotation. Greatly reduced. ...
