Abstract

The invention belongs to speed reducers, and specifically relates to a nutation oscillating-tooth speed reducer. The nutation oscillating-tooth speed reducer is characterized in that a bull-eye type nutation-disc oscillating-tooth transmission mechanism comprises a nutation disc, a nutation bearing, a bearing sleeve, an end cover, bull-eye type round-ball rolling pair sets, a fixed disc tooth slot and a rotating disc tooth slot; each bull-eye type round-ball rolling pair set is formed by arraying a plurality of bull-eye type round-ball rolling pairs; and each bull-eye type round-ball rolling pair consists of a round ball, a round ball check ring, a rolling ball and an oscillating-tooth main body. The speed reducer is reasonable, novel and special in design, has a compact structure, can solve the problem that the similar speed reducer has a complex structure, large volume and low transmission efficiency, and also can prevent the defect of top cutting generated when the transmission ratio is great; and simultaneously, the speed reducer has the characteristics of high transmission precision, high transmission rigidity, high transmission efficiency, low noise, big transmission ratio, long service life, few parts, small volume, light weight, convenience for installment, manufacturing and maintenance, good bearing capability, no need of output mechanisms, and the like.

Description

technical field [0001] The invention belongs to a speed reducer, in particular to a nutating movable tooth speed reduction device. Background technique [0002] In the mechanical field, the traditional transmission method adopts gear transmission; its meshing teeth are usually in the form of fixed teeth, and in this way a certain clearance must be reserved for meshing. Due to the existence of gaps, the requirements of the prior art for high load capacity, high precision, high reliability, large speed ratio, and small-volume mechanical transmission cannot be met. In order to eliminate the backlash and make up for the deficiency of conventional gear transmission, a movable meshing gear transmission method is adopted at this stage, which can realize zero-backlash transmission. In recent years, the movable tooth transmission mechanism has also been deeply discussed and researched and developed at home and abroad. The applicant once applied to the State Intellectual Property Of...
