Abstract

The invention relates to a harmonic speed reducer. The harmonic speed reducer comprises a rigid gear, a flexible gear, a shaft assembly, a wave generator assembly and a casing, wherein the inner wall of the rigid gear is provided with teeth; the flexible gear is arranged in the rigid gear and is engaged with the rigid gear through the teeth; the wave generator assembly is arranged in the flexible gear; the casing is arranged on the exterior; the rigid gear is fixedly arranged in the casing; the number of teeth of the rigid gear is greater than the number of teeth of the flexible gear; the shaft assembly consists of an input shaft and an output shaft; the wave generator assembly is arranged on the input shaft of the shaft assembly through a shaft penetrating hole in the center; the wave generator assembly comprises a double-semicircular wave generator and a flexible bearing, and the flexible bearing is sheathed on the outer surface of the double-semicircular wave generator; the double-semicircular wave generator consists of a column body and two semicircular column bodies, a shaft penetrating hole is formed in the center of the column body, and the two semicircular column bodies are symmetrically arranged at both sides of the column body. The harmonic speed reducer has the beneficial effects that the structure is simple, and the difficulty in manufacturing is effectively reduced; the counterforce of the rigid gear onto the teeth of the flexible gear is uniform, the working property of the speed reducer is effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a harmonic reducer. Background technique [0002] In the field of mechanical transmission, there are various reducers according to their characteristics, scope of application and occasions of use. Harmonic reducer is a reducer with simple structure, compact structure, large transmission ratio and high transmission accuracy, so it has been widely used in the field of mechanical engineering, especially in the robot industry. However, the current harmonic reducer usually uses an elliptical wave generator, and there are technical problems that the elliptical wave generator is difficult to design, process and detect. Therefore, there are very few companies capable of developing, designing, and producing harmonic reducers; and the cost and selling price are much higher than ordinary reducers. Contents of the invention [0003] In order to solve the above technical problems, t...
