The invention relates to a speed reducer, in particular to a dual-planetary-gear differential speed reducer. The speed reducer comprises a machine base part, a stator part, a first rotor part, a second rotor part, a first controller, a second controller and a dual-planetary-gear differential part; and in the running process of the speed reducer, the output rotating speed of a first output shaft isrelated to the rotating speed difference of two electric motors, the two electric motors can be in the high-speed running state all the time, under the state that the rotating directions of the two electric motors are not changed, the rotating direction of the first output shaft of the speed reducer can be changed, a load device is driven to achieve frequent acceleration and deceleration, and frequent starting and stopping, and even, the function of frequently changing the rotating direction of the load device can be achieved. The speed reducer can ensure that the electric motors can run under the work state of higher efficiency, and the response speed is improved while the speed reducer changes the rotating direction of the load device; and the speed reducer meets the control requirementof the special load device, that is, the output power of the electric motors can be adjusted while the electric motors output the same rotating speed.
Description
technical field [0001] The present invention is a double planetary gear differential reducer, which relates to a reducer, in particular to a double planetary gear which adopts the speed difference when two electric motors respectively drive two planetary gear reducers to obtain a low speed output Differential speed 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 robots with sma...
