Problems solved by technology
[0002] Since the seat track motor outputs torque at both ends, there is no axial force during the motor movement, and there is a certain axial gap in the design of the motor, so the motor will appear axial movement during operation, thus Affect the vibration and noise of the motor; in order to eliminate the axial movement, the motor manufacturer uses a wave gasket or a silicone damping gasket on the rotor shaft, which has a certain effect on eliminating the axial movement of the motor, but it cannot completely eliminate it. The friction sound and vibration of the motor

Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] It should be noted that when a component is said to be “fixed” to another component, it may be directly on the other component or there may be another intermediate component through which it is fixed. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be another intermediate component at the same time. When a component is said to be "set on" another component, it may be set d...

The invention discloses a compression sleeve for eliminating axial movement of a micro-motor rotor, the compression sleeve is provided with a mounting hole, the mounting hole penetrates through the compression sleeve for eliminating the axial movement of a micro-motor rotor, the side wall of the compression sleeve for eliminating the axial movement of the micro-motor rotor is provided with a plurality of cavities, the cavities are communicated with the mounting hole, and the cavities are arranged in a staggered manner along the height direction of the side wall. The two ends of the compression sleeve for eliminating the axial movement of the micromotor rotor abut against the motor rotor and the bearing respectively, the cavity structure of the compression sleeve has the deformation recovery capacity, in the operation process of the motor, under the influence of axial force, the compression sleeve is in a pressed state, the axial movement of the rotor is limited due to the certain deformation recovery capacity of the compression sleeve. Therefore, the effect of eliminating the axial movement of the rotor is achieved. The invention also relates to a motor comprising the compression sleeve.
Description
technical field [0001] The invention relates to a motor, in particular to a compression sleeve for eliminating axial movement of a rotor of a micro-motor. Background technique [0002] Since the seat track motor outputs torque at both ends, there is no axial force during the motor movement, and there is a certain axial gap in the design of the motor, so the motor will appear axial movement during operation, thus Affect the vibration and noise of the motor; in order to eliminate the axial movement, the motor manufacturer uses a wave gasket or a silicone damping gasket on the rotor shaft, which has a certain effect on eliminating the axial movement of the motor, but it cannot completely eliminate it. The friction sound and vibration of the motor are eliminated. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a compression sleeve that can eliminate the axial movement of th...
