High-level variable elliptic swing movable tooth transmission device

Abstract

The invention discloses a high-level variable elliptic swing 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, the output shaft rack is provided with a movable tooth pin, swing movable teeth are arranged on the movable tooth pin in a sleeving manner 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 curve of the input shaft shock machine is a high-level variable elliptic curve or an equidistant curve of the same. The high-level variable elliptic profile curve is the high-level variable elliptic curve or the equidistant curve of the same generated according to the high-level variable elliptic forming equation. According to the high-level variable elliptic swing movable tooth transmission device, the swing movable tooth and the movable tooth pin are employed to replace traditional eccentric or steel ball movable tooth, so that wear caused by rolling and slipping friction is greatly reduced; the high-level variable elliptic profile is used as the profile curve of a shock cam, and the composition curve of the high-level variable elliptic profile is an arc due to the high-level variable elliptic forming principle, thus having the advantages of easiness to process, high precision, large load capacity and the like.

Description

technical field [0001] The invention relates to the technical field of transmission mechanisms, in particular to a high-order denatured elliptical swing movable tooth transmission device. Background technique [0002] Various deceleration mechanisms are widely used in production and equipment manufacturing. Movable gear transmission is widely used as a deceleration mechanism with the advantages of compact structure, stable transmission, and large reduction ratio.
