Planetary harmonic composite reducer motor

Abstract

A disclosed planetary harmonic composite reducer motor comprises a first flange cover, a first steel wheel is arranged on the outer surface of the lower end of the first flange cover, a planet carrier supporting shaft is arranged on the outer surface of the upper end of a planet carrier, and a planet wheel is arranged on the outer wall of the planet carrier supporting shaft; a first sun gear is arranged on the outer surface of the lower end of the planet carrier, a bearing is arranged on the outer wall of the first sun gear, a second sun gear is arranged on the outer surface of one side of the first sun gear, second sun gear inner teeth are arranged on the inner wall of the second sun gear, and a flexible gear is arranged on the outer surface of the lower end of the second sun gear. The planetary harmonic composite speed reducer motor solves the problems that an existing motor is not high in integration level and insufficient in torque under the condition that the size is certain, and has the advantages that the planetary harmonic composite speed reducer is integrated into the space of the inner ring of the stator coil, the size is greatly reduced on the premise that the large torque is guaranteed, and better use prospects are provided.

Description

technical field [0001] The invention relates to the field of planetary harmonic compound reducer, in particular to a planetary harmonic compound reducer motor. Background technique [0002] The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. Ordinary The reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio. The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator, and is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It has a wide var...

AI Technical Summary

Problems solved by technology

[0003] With the development of science and technology, people's demand for high-torque, small-volume, and highly-integrated motors is becoming more and more significant. However, the existing high-torque motors are generally connected with a motor and a reducer, which are large in size and low in integration. High, and some small, highly integrated motors generally have a relatively small reduction ratio, which is not enough to provide high torque
