Description

Technical Field

[0001] The utility model relates to the field of spring washers, in particular to a spring washer used for a motor end cover. Background Art

[0002] Spring washers are commonly used in equipment installation. Compared with flat washers, spring washers can not only prevent nuts from scratching the mounting surface, but also increase the preload force and friction. However, spring washers are not closed, so they have cross-sections. When the nut is rotated to tighten the mounting part, the end face of the spring washer is easy to rub against the surface of the mounting part, causing scratches.

[0003] The motor end cover is one of the components of the motor. The accuracy of the motor end cover installation can easily affect the position of the brush piece in the motor, so the installation requirements of the motor end cover are relatively high. Therefore, it is necessary to improve such a structure to overcome the above defects. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a spring washer for a motor end cover. The utility model is achieved through the following technical solutions:

[0005] A spring washer for a motor end cover comprises a washer body, wherein the washer body is not closed and is spiral-shaped, a first inclined surface is arranged at one end of the washer body, a second inclined surface is arranged at the other end of the washer body, the first inclined surface is located above the second inclined surface, a first mounting groove is arranged at a position close to the first inclined surface on the bottom surface of the washer body, and a first rubber block is fixedly arranged in the first mounting groove.

[0006] In the above technical solution: the gasket body is used to realize the basic function of the gasket; the gasket body is spirally shaped so that the gasket body can be compressed to provide a preload; the first inclined surface and the second inclined surface are used to guide the gasket body when it is compressed, so that the two ends of the gasket will not collide and cause deformation; the first mounting groove is used to install the first rubber block; the first rubber block is used to provide friction to prevent the gasket body from rotating, thereby preventing the sharp edge at the end face from scratching the surface of the end cover.

[0007] The utility model is further configured as follows: the first inclined plane is parallel to the second inclined plane.

[0008] In the above technical solution: the first inclined surface is parallel to the second inclined surface, so that during the compression process, if the first inclined surface is in contact with the second inclined surface, the gasket body can expand more smoothly through the contact between the first inclined surface and the second inclined surface.

[0009] The utility model is further configured as follows: a second installation groove is provided on the top surface of the gasket body at a position close to the second inclined surface, and a second rubber block is fixedly provided in the second installation groove.

[0010] In the above technical solution: the second mounting groove is used to set the second rubber block, and the second rubber block is used to provide friction to reduce scratches on the motor mounting surface.

[0011] The utility model is further configured as follows: the thickness of the first rubber block is greater than the first installation groove, and the width of the first rubber block is less than the first installation groove.

[0012] In the above technical solution: the thickness of the first rubber block is greater than the first installation groove, and the width is smaller than the first installation groove, so that the first rubber block can fully contact the end cover after deformation, thereby increasing the friction force by increasing the contact area.

[0013] The utility model is further configured as follows: the thickness of the second rubber block is greater than the second installation groove, and the width of the second rubber block is less than the second installation groove.

[0014] In the above technical solution: the thickness of the second rubber block is greater than the second installation groove, and the width is smaller than the second installation groove, so that the second rubber block can fully contact the end cover after deformation, thereby increasing the friction force by increasing the contact area.

[0015] The utility model discloses a spring washer for a motor end cover. Compared with the prior art:

[0016] 1. The utility model provides a first installation groove and a second rubber block, so that when the spring washer is deformed during installation, the friction force can be increased, thereby preventing the washer body from rotating, and further preventing the end face of the washer body from scratching the motor end cover; 2. The utility model also provides a second installation groove and a second rubber block, so that the end face of the washer body can be prevented from scratching the installation surface of the motor.
