Problems solved by technology

Compared with the RV reducer or harmonic reducer, the transmission ratio of the planetary gear reducer is small, which cannot meet the requirements of the joint robot for the transmission ratio
[0003] During the operation of joint robots, electric vehicles, electric mopeds, and washing machines, frequent accelerations, decelerations, frequent starts, stops, and even frequent changes in the direction of rotation of their motors are required. These motion characteristics make the motors work at low efficiency. run in state

Abstract

The invention discloses a dual-rotor input planet-gear speed reducer, and relates to a speed reducer. The speed reducer comprises a shell component, an engine base component, a controller one, a controller two, a stator component, an external rotor component, an internal rotor component, a rotating shaft component, a gear ring, and a planet-gear component; in the operation process of the speed reducer, the output rotation speed of an output shaft one is related to rotation speed difference between two motor rotors; two motor rotors are always in the high-speed operation state, the rotating direction of the output shaft one of the speed reducer can be changed under the state of maintaining the unchanged rotation directions of two motor rotors, thereby driving a load device to realize the functions of frequently accelerating and reducing speed, frequently starting and stopping, even frequently changing the rotation direction of the load device. The speed reducer disclosed by the invention can ensure the motor to operate under the working state with high frequency, and improve the response speed when the speed reducer changes the rotation direction of the load device.

Description

technical field [0001] The present invention is a double-rotor input planetary gear reducer, which relates to a reducer, in particular to a double-rotor motor that drives the planetary gear reducer by using the speed difference between the rotors of the two motors to obtain a low-speed output. The rotor enters the planetary gear reducer. Background technique [0002] The reducer of joint robot mainly adopts RV reducer. The RV reducer has the advantages of large transmission ratio and large output torque. The disadvantages of complex structure and high cost of RV reducer also restrict the popularization and application of RV reducer. In the application of joint robots, RV reducers gradually replace harmonic reducers. The strength of the flexible gear of the harmonic reducer is low, resulting in a small output torque and a short service life of the harmonic reducer. The RV reducer is used for joint robots with large load torque, and the harmonic reducer is used for joint r...
