Mechanical and electrical integration harmonic reducer

Abstract

The invention provides a mechanical and electrical integration harmonic reducer. The harmonic reducer is arranged in the center position of the interior of a shell. An outer rotor brushless permanentmagnet motor is arranged on the periphery of the interior of the shell. Through mechanical and electrical integration, the space in the shell is made full use of, the magnetic intensity of a rare earth permanent magnet outer rotor is large, and the efficiency of the motor under the high-speed running state is high. The harmonic reducer is mounted in the center of a coreless permanent magnet motorand is coaxial with the outer rotor brushless permanent magnet motor at different speeds. According to a wave generator, a flexible outer gear ring is supported through multiple pulleys and becomes anelliptic outer gear ring. When the wave generator rotates at high speed, the flexible outer gear ring becomes the fluctuation distortional elliptical outer gear ring rotating at low speed and is small in fluctuating resistance and low in noise. The mechanical and electrical integration harmonic reducer is small in size, light in weight, high in bearing capacity, large in transmission ratio and high in transmission precision and is widely applied to the machinery field, especially in the robot manufacturing field.

Description

technical field [0001] The invention relates to a harmonic reducer, specifically a mechanical-electrical integrated harmonic reducer. Background technique [0002] The electromechanical integrated harmonic reducer is a kind of harmonic reducer that integrates the motor and the harmonic reducer.
