Description

technical field [0001] The invention relates to the field of reducers, in particular to a harmonic reducer. Background technique [0002] Harmonic gear reducer is composed of a fixed internally toothed rigid wheel, a flex spline, and a wave generator that causes radial deformation of the flex spline. The harmonic gear reducer is a new type of transmission structure in the gear reducer. It uses flexible gears to generate controllable elastic deformation waves, causing the teeth of the rigid gear and the flexible gear to transmit power and motion relative to each other. This kind of transmission is essentially different from general gear transmission, and has particularity in meshing theory, set calculation and structural design. The harmonic reducer has the advantages of high precision and high bearing capacity. Compared with the ordinary reducer, its volume and weight are reduced by at least 1 / 3 due to the use of 50% less materials. [0003] Like the planetary gear transmi...
