Polyhedral movable tooth transmission device

Abstract

The invention discloses a polyhedral movable tooth transmission device. An input shaft shock machine is arranged in a manner of being concentric with an output shaft rack and a central internal gear, the central internal gear is fixedly connected with an engine body base, movable teeth are uniformly distributed in the slot of the output shaft rack and meanwhile contacted with the tooth profile of the input shaft shock machine and the tooth profile of the central internal gear; the tooth profile of the input shaft shock machine is a polyhedral profile. The polyhedral tooth profile is a non-circular profile curve of four or more surfaces obtained according to a polyhedral design method. The tooth profile curve of the central internal gear is the outer contour envelope curve of the movable tooth, which is formed by employing the input shaft shock machine as a shock machine and carries out movable tooth movement with the output shaft rack and the movable teeth. According to the polyhedral movable tooth transmission device, the polyhedral profile is used as the profile curve of a shock cam, a movable tooth reducer provided with the profile has the advantages of stable dynamic balance, good curve transition, large load capacity and the like; the composition curve of the polyhedral profile is an arc due to the polyhedral forming principle, thus having the advantages of easiness to process, high precision and the like.

Description

technical field [0001] The invention relates to the technical field of transmission mechanisms, in particular to a multi-face movable tooth transmission device. Background technique [0002] Various deceleration mechanisms are widely used in production and equipment manufacturing. Sliding tooth transmission is widely used as a deceleration mechanism with the advantages of compact structure, stable transmission, and large reduction ratio. However, the traditional shock cam is difficult to process and has low load capacity. The shortcomings of weak and low curve efficiency limit the scope of use.
