Problems solved by technology

[0004] The above existing technical solutions have the following defects: when the existing motor body is moving, there is a stock of axial movement, which will cause the output shaft to move back and forth in the axial direction in the rotating cavity, resulting in the transmission between the worm and the worm wheel. The tooth surfaces squeeze each other, which makes the lifting motor unit generate noise during operation, which affects the use

Abstract

The present invention relates to the technical field of lifting motors, relates to a noise-reducing motor unit for lifting and its production method, and mainly relates to a noise-reducing motor unit for lifting, including a motor base, a motor body, and a reduction box. The motor body There is a worm on the output shaft of the gear box, and there is a rotating chamber for the worm to rotate in the reduction box. The end of the output shaft is provided with a rotating ball, and the rotating chamber is provided with two The two bearing sleeves are used to limit the rotation of the ball in the axial and radial directions. The invention has the following effects: the bearing sleeve can limit the rotating ball in the axial direction and the radial direction, and reduce the movement of the output shaft in two directions, thereby realizing noise reduction.

Description

technical field [0001] The invention relates to the technical field of lifting motors, in particular to a noise reduction motor unit for lifting and a production method thereof. Background technique [0002] The speed of lifting and closing of automobile door and window glass and opening and closing of sunroof is relatively slow, which generally needs to be completed by a lifting motor unit, which needs to achieve low speed and high torque output. The existing lifting motor unit is completed by the combination of a DC motor and a reduction box. [0003] General lifting motor units, such as figure 1 As shown, the motor body 100 is included, the motor body 110 is installed in the motor body 100, a reduction box 111 is connected by bolts on the motor body 100, the output shaft 112 of the motor body 110 is provided with a worm 113, and the worm 113 is rotatably connected in the reduction box 111. There is a rotating chamber 120 for the worm 113 to rotate in the reduction box 1...
