The invention relates to a planetary roller gear speed reducer and an implementation method thereof. The planetary roller gear speed reducer comprises a driving wheel seat, a driven wheel seat, a driving shaft, a driven shaft and a plurality of satellite wheels. The implementation method of the planetary roller gear speed reducer comprises the following steps that the driving shaft is driven by amotor to rotate, and the driving shaft rotates to drive accompanying rollers on the satellite wheels to rotate; the driving shaft is in engaged transmission with the satellite wheels through the accompanying rollers, and a gear on the driving shaft is in rolling friction with the accompanying rollers; and the satellite wheels are in meshing transmission with a fixed gear ring through the accompanying rollers, the accompanying rollers are in rolling friction with the fixed gear ring, and the fixed gear ring is fixedly connected with the driving wheel seat and the driven wheel seat, so that thedriving shaft drives the driven shaft to rotate. According to the planetary roller gear speed reducer, meshing transmission is achieved through rolling contact between the rollers and the gear, meshing transmission of sliding contact between an existing gear and the gear is replaced, the return stroke gap is reduced, the precision and transmission efficiency of the speed reducer are greatly improved, the return stroke gap is slowly increased in the using process, and the service life of equipment is prolonged.
Description
technical field [0001] The invention relates to the technical field of reducers, in particular to a planetary roller gear reducer and an implementation method thereof. Background technique [0002] At present, the planetary gear reducer mainly adopts the internal meshing mechanism. The principle is that there are more than two planetary gears between the sun gear and the ring gear in the center, and the ring gear is fixed on the frame. Occlusion transmission has a large backlash, and has a large friction coefficient and wear on the gears. During the use of the reducer, the backlash will continue to increase, which will affect the service life. Contents of the invention [0003] This application provides a planetary roller gear reducer, which is used to solve the problem that the traditional planetary gear reducer transmits power through tooth-to-tooth engagement, and there is a large backlash, which causes great wear on the gears and the backlash continues to increase. , ...
