Abstract

The invention provides a universal planetary gear reducer for an outer rotor type motor. The universal planetary gear reducer comprises a motor, a flange plate type sun wheel, a planet wheel and planet carrier assembly, an inner gear ring and a supporting frame assembly, and the flange plate type sun wheel comprises a flange plate and a gear shaft fixed at the center of the flange plate; the flange plate of the flange plate type sun wheel is fixed to the rotating center of the motor, the gear shaft of the flange plate type sun wheel is connected with a planet wheel and a planet carrier of the planet wheel and planet carrier assembly, the planet wheel of the planet wheel and planet carrier assembly meshes with the inner gear ring, and the planet carrier of the planet wheel and planet carrier assembly is used for outputting power of the motor; and the supporting frame assembly is arranged outside the motor, the flange plate type sun wheel and the planet wheel and planet carrier assembly in a sleeving mode and is fixed to the motor and the inner gear ring. The shape of the motor is not changed, and speed reducers can be additionally arranged on most outer rotor type motors only by replacing parts connected with the motors in order to adapt to different motors.

Description

technical field [0001] The invention belongs to the technical field of motor reducers, and in particular relates to a planetary gear reducer common to outer rotor motors. Background technique [0002] The rapid development of legged robot technology has led to more agile movements of the legged robot, so higher requirements are put forward for the joints of the legged robot: the joints are small in size, light in weight, large in torque, and fast in response. However, the existing small-volume, low-torque motors cannot meet the torque requirements of legged robots, and the motor needs to be decelerated to increase the torque. [0003] 1. Due to the large size and heavy weight of the conventional synchronous belt deceleration and external gear deceleration schemes, it is difficult to design the robot joints. The increase in the volume and weight of the robot also increases the load on the motor itself, making it difficult to further develop the legged robot. [0004] 2. The ...
