Technical Field

[0001] The utility model discloses a bearing seat riveted motor end cover which can prolong the service life of the bearing seat and belongs to the field of motor end cover equipment. Background Art

[0002] The bearing seat riveted to the motor end cover is a mechanical connection method used to fix the connection between the bearing seat and the motor end cover. In the structure of the motor, the bearing seat is a component used to support and position the bearing, while the motor end cover is the shell that wraps the internal components of the motor. In order to ensure a firm connection between the bearing seat and the motor end cover, riveting technology is often used. Riveting is a method of forming a permanent connection by combining fixings such as rivets or rivet nuts with the connected parts (such as the bearing seat and the motor end cover). In the process of riveting the bearing seat to the motor end cover, the rivets or rivet nuts will pass through the holes of the bearing seat and the motor end cover, and the two will be firmly fixed together by pressing or impacting.

[0003] In the prior art, after the motor bearing seat is used for a long time, the bearing connection may become stuck or inflexible due to the long-term accumulation of dust. The motor end cover cannot provide dust cover protection for the motor bearing seat, which shortens the service life of the motor bearing seat. Therefore, the motor bearing needs to be cleaned regularly. Since the installation method of the end cover is cumbersome, it is difficult to disassemble the end cover and clean the motor bearing, which reduces the convenience of cleaning the motor bearing.

[0004] In summary, the utility model provides a bearing seat riveted motor end cover which prolongs the service life of the bearing seat, so as to solve the above problems. Utility Model Content

[0012] Furthermore, the connecting ring is fixedly connected to the fixing ring, and the rotating ring is rotatably connected to the connecting ring.

[0013] Beneficial effects of the utility model:

[0014] The sealing rubber ring can increase the friction and sealing of the connection between the mounting ring and the rotating ring sleeve, so that when the motor output end drives the mounting ring to rotate, the mounting ring can drive the rotating ring to rotate through the sealing rubber ring, which does not affect the rotation of the motor output end. At the same time, the sealing rubber ring can block dust in the external air, thereby providing dust protection for the bearing seat at the connection between the motor output end and the motor, effectively reducing the cleaning frequency of the motor bearing seat and extending the service life of the motor bearing seat.
