Abstract

The invention provides a harmonic reducer. The harmonic reducer comprises a flexible wheel, a rigid wheel, a wave generator and a roller bearing. The roller bearing is provided with an outer ring and an inner ring. The flexible wheel is connected with the outer ring. The rigid wheel is connected with the inner ring. The wave generator comprises a cam. The cam is provided with a long shaft integrally extending out from the end face of the cam. The cam and the long shaft are hollow. An auxiliary guide pipe is arranged in a hollow space. One end of the auxiliary guide pipe is connected with the rigid wheel. When the cam is sleeved with the flexible wheel, the flexible wheel is oval, teeth at the two ends of the flexible wheel in the long shaft direction are completely engaged with teeth of the rigid wheel, and teeth at the two ends of the flexible wheel in the short shaft direction are kept disengaged from the teeth of the rigid wheel. By the adoption of the harmonic reducer, the requirements of a collaborative robot on the compact and flexible design of the harmonic reducer can be fully met, the harmonic reducer is small in size and low in weight, and a module assembly comprising a frameless direct-driven torque motor, a low-pressure direct-current driver, a braking device, a double-feedback device and the like can be directly integrated to the harmonic reducer easily.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a harmonic reducer. Background technique [0002] At present, collaborative robots have gradually become the development trend of industrial robots, and their market share is increasing. Due to the unique advantages of high load capacity, large transmission ratio, small size, light weight, stable transmission and high transmission precision, the harmonic reducer has become an essential component of the collaborative robot joint. Although the harmonic reducer has many of the above advantages, it cannot fully meet the requirements of the collaborative robot for its compact structure, good flexibility, convenient routing and installation. [0003] Therefore, aiming at the above problems, the present invention proposes a further solution. Contents of the invention [0004] The present invention aims to provide a harmonic speed reducer to overcome the deficiencies ...
