Abstract
The invention relates to a cosine shock wave push rod movable teeth transmission device which is characterized in that an input shaft shock wave generator is installed coaxially with an output shaft rack and a central internal gear; the central inner gear is fixedly connected with a machine body base; movable teeth are uniformly distributed in a groove of the output shaft rack and simultaneously in contact with the tooth profile of the input shaft shock wave generator and the tooth profile of the central internal gear; the tooth profile of the input shaft shock wave generator is a cosine tooth profile in which a cosine curve or an equidistant curve of the cosine curve serves as a profile contour curve and a cosine teeth profile conjugate curve, or the equidistant curve of the cosine curve serves as the profile contour curve. A tooth profile curve of the central internal gear is a movable teeth external profile enveloping curve which is formed by that the central internal gear performs a push rod movable teeth movement with the output shaft rack and the movable teeth by taking the input shaft shock wave generator as the shock wave generator. The cosine shock wave profile is used as the profile curve of a shock wave cam, the processing technology difficulty is greatly lowered, the size and the accuracy are well guaranteed. A movable teeth reducer adopting the cosine shock wave profile has the advantages of stable dynamic balance, good curve transition, capability of bearing heavy load and the like.
