Technical Field
[0001] The utility model relates to the field of reducers, in particular to a motor-integrated planetary reducer. Background Art
[0002] A planetary reducer is a reduction device composed of a planetary gear, a sun gear and an inner ring gear. It is widely used in regulating the speed and torque of a transmission motor in mechanical transmission. However, existing planetary reducer transmission motors and reducers are often assembled in separate parts, which makes it inconvenient for workers to quickly and stably combine and use the planetary reducers during use, and the functionality is not strong during use. Therefore, an integrated motor planetary reducer has been derived. However, the existing integrated motor planetary reducer has the following disadvantages: when connected to the motor, it is a complete reducer structure, which leads to many accessories connected between the motor and the reducer, thereby increasing the cost. For this reason, a motor-integrated planetary reducer is proposed. Utility Model Content
