Detailed Description
The utility model is further described below with reference to the drawings and detailed description.
Referring to fig. 1 to 5, the structure for eliminating abnormal sound caused by axial movement of the window regulator motor shown in the drawings comprises a casing assembly 10, a reduction box assembly 20, a brush holder assembly 30 and an armature assembly 40, wherein the armature assembly 40 and the brush holder assembly 30 are arranged in the casing assembly 10 and the reduction box assembly 20. The brush holder assembly 30 is installed at the middle of the armature assembly 20.
The utility model is characterized in that: the armature assembly 40 is provided with a wear-resistant spacer 51, 52 at each end, and the armature assembly 40 is supported in the housing assembly 10 and the reduction gearbox assembly 20 at each end by the corresponding wear-resistant spacer 51, 52. Meanwhile, a rubber piece 60 is arranged between the wear-resistant gasket 52 positioned at the tail of the armature assembly 40 and the reduction gearbox assembly 20 and is used for eliminating abnormal axial movement sound of the motor.
To further enhance the service life and the actuation sound of the motor, the head and tail portions of the armature assembly 40 are supported in the housing assembly 10 and the reduction box assembly 20 by respective straight bearings 71, 72.
In order to ensure coaxiality of the adjusting housing assembly and the reduction gearbox, and to ensure stable operation of the armature assembly 40, the armature assembly 40 is supported in the brush holder assembly 30 by a ball bearing 80.
To ensure that the armature assembly 40 does not play axially throughout the life cycle (35000 cycles), the rubber interference is set to 1.2mm. In order to absorb manufacturing errors of parts, a movable space of 0.5mm is reserved between the wear-resistant gasket 52 and the reduction gearbox assembly.
In order to improve the service life and the actuation sound of the armature assembly 40 motor, the material of the straight bearings 71, 72 and the ball bearing 80 is copper-based powder alloy, the material of the wear-resistant gaskets 51, 52 is PEEK, the material of the rubber member 60 is EPDM, and the hardness of the rubber member 60 is HS 85+ -5.
