Abstract

The invention discloses a motor reducer, which comprises an output shaft, a motor and a gear reducing mechanism, wherein the output shaft is coaxially arranged inside an electronic rotor of the motor and fixedly connected with an output gear of the gear reducing mechanism; and an input gear shaft of the gear reducing mechanism is inserted into an axle hole of the motor rotor. The input gear shaft of the gear reducing mechanism is inserted into the axle hole of the motor rotor, so that the motor and the gear reducing mechanism are effectively integrated into a whole. The motor rotor is used as a gear carrier, so that the entire motor reducer is simple and compact in structure, small in axial size and small in floor area. In addition, the speed reducing range of a gear differential mechanism is increased, thereby large reduction ratio output is achieved, the condition that the motor runs at high speed is kept and the use efficiency of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a motor reducer. Background technique [0002] The motor has many advantages such as high energy conversion efficiency, energy saving, and environmental protection, so it has been widely used in industrial production and life. In equipment such as electric vehicles, electric tricycles, electric vehicles, washing machines, etc., motors are indispensable. less equipment. Ordinary motors have a high speed. In order to obtain a suitable output speed, the motor needs to be decelerated in practical applications. At present, the commonly used method is to transmit the motor to the reducer and decelerate through the first-stage pulley, and set a first-stage pulley in the reducer. The planetary gear reduction mechanism is used to complete the deceleration of a certain speed ratio. In actual use, such a motor reducer does not have high motor efficiency, cannot achieve a large reduction ...
