Abstract
The invention relates to a flexible gear and a harmonic reducer with the flexible gear and a rigid gear. When not stressed, flexible gear teeth on the flexible gear and rigid gear teeth on the rigid gear maintain surface contact in a complete mesh state or a semi-mesh state, and after stressed, the flexible gear teeth on the flexible gear and the rigid gear teeth on the rigid gear are turned intosurface contact in the complete mesh state or the semi-mesh state, so that edge mesh and sharp point mesh can be avoided, the situation that serious tooth surface abrasion generated when the flexiblegear and the rigid gear are engaged is effectively avoided, and formation of an oil film is facilitated; and furthermore, stress concentration at an abraded part can be avoided, the bearing strength of the flexible gear and the rigid gear can be ensured, and the service lives of the flexible gear and the rigid gear can be easily prolonged.
Description
Technical field [0001] The invention relates to a flexible wheel, a rigid wheel matched with the flexible wheel and a harmonic reducer with the flexible wheel and the rigid wheel. Background technique [0002] The harmonic reducer is mainly composed of four basic components: a wave generator, a flexible wheel, and a rigid wheel. It is a kind of flexible wheel that is equipped with a flexible bearing to make the flexible wheel produce controllable elastic deformation and mesh with the rigid wheel for transmission. Gear transmission for movement and power. The existing harmonic reducer deforms the flexspline through the action of the wave generator, and forces the teeth of the flexspline part to mesh with the teeth of the rigid part. Edge meshing and sharp-point meshing usually occur at the meshing position. , It is easy to produce serious wear at the edge meshing and sharp point meshing, which is not conducive to the formation of oil film on the surface of the rigid wheel and the...
