Abstract

The invention provides a flex wheel and a harmonic reducer including the same. The flex wheel includes: a flex wheel body, the flex wheel body is configured as a cylindrical structure; the first end of the flex wheel body forms a tooth portion, the A plurality of external teeth are formed on the outer wall of the tooth portion along its circumferential direction, and a reinforcing structure is arranged between two adjacent external teeth, and the reinforcing structure includes a plurality of arc segments to increase the two external teeth the thickness of the part in between. The invention can improve the strength of the tooth portion of the flexible wheel and increase the service life of the flexible wheel, so that the harmonic reducer has a longer life and better reliability.

Description

technical field [0001] The invention relates to the technical field of harmonic reducers, in particular to a flexible wheel and a harmonic reducer including the same. Background technique [0002] With the transformation and upgrading of intelligent manufacturing, higher precision and reliability requirements are put forward for the high-precision transmission of industrial robot harmonic reducers. As one of the core components of robot transmission, harmonic reducers are more The wave reducer has the characteristics of small size, large reduction ratio, large number of meshing teeth at the same time, stable transmission, high bearing capacity and high transmission precision, so it is widely used in aerospace, military, industrial robots and so on. At present, the main problem that restricts the development of the harmonic reducer industry is the life problem, and the fracture of the tooth root of the flexible wheel and the tearing of the flange are the main reasons for the ...
