Abstract

The invention discloses a non-clearance elastic gear transmission device which comprises a first gear and a second gear meshed with the first gear. A cantilever structure is arranged on the tooth sideof all gear teeth of the first gear and deforms during gear meshing to form elastic-meshing transmission. Through the technical scheme, elastic-meshing transmission can be realized by combining the bending and compressing deformation of a conventional rigid meshing movement elastic structure and the meshing movement of the gear teeth, the transmission clearance in ordinary gear transmission can be eliminated, and transmission noise can be reduced.

Description

technical field [0001] The invention relates to a transmission device, specifically but not exclusively, to a backlash-free elastic gear transmission device. Background technique [0002] The general gear transmission device transmits power and motion through the rigid contact of two gear teeth. The teeth will be slightly deformed during the transmission process. In order to solve the adverse effects of gear deformation on power transmission and motion transmission, the tooth shape The method of shape modification improves the stability and bearing capacity of the transmission. Due to the small amount of gear deformation, if the multi-teeth meshing method is adopted, higher precision requirements are imposed on the manufacture of gears. For example, the RV reducer requires the manufacturing accuracy of transmission parts to reach about 2 microns, which will lead to a sharp increase in processing costs. . At the same time, due to the existence of machining errors and deform...
