Abstract

The invention discloses a harmonic reducer. The harmonic reducer comprises a rigid circular spline; a flexible output device is drivingly connected inside the rigid circular spline and composed of a flexible gear and an output shaft which are integrally formed. The invention also provides a machining process of the harmonic reducer. The machining process comprises a right circular spline machining step, a flexible output device machining step and an assembly step. An external roller pin groove and the rigid circular spline are integrally formed; the flexible gear, a bearing track, an internal roller pin groove and the output shaft are integrally formed. According to the machining process of the harmonic reducer, the external roller pin groove and the rigid circular spline are integrally formed; during the flexible output device machining step, the flexible gear, the bearing track, the internal roller pin groove and the output shaft are integrally formed and accordingly are simple in structure, so that error accumulation due to separate machining can be greatly reduced, the product precision can be improved, the concentricity and the location degree of the rigid circular spline, the flexible gear and the output shaft are ensured, the service life of the harmonic reducer can be prolonged by 50%, and the production cost can be reduced by 20-30%.

Description

technical field [0001] The invention relates to a reducer and its processing technology, in particular to a harmonic reducer and its processing technology. Background technique [0002] Harmonic reducer is a new type of high-precision transmission reduction device. This kind of reducer has large torque, high transmission ratio, light weight and small size and is widely used. [0003] The traditional harmonic reducer includes a rigid wheel. The inner transmission of the rigid wheel is connected with a flexible spline and an output shaft. The flexible spline and the output shaft are fixedly connected. Crossed roller bearings generally consist of inner rings, outer rings and cross needle rollers. [0004] At present, the inner ring of the crossed roller bearing used in the harmonic reducer mostly adopts a groove similar to the structure of the inner ring directly processed on the outer circumference of the output shaft; while the outer ring of the crossed roller bearing is usu...
