SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a mute motor bearing with a damping function, so as to solve the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a silent motor bearing with shock-absorbing function, includes the bearing, the inboard intermediate position department fixedly connected with rubber packing ring of bearing, rubber packing ring inboard is equipped with the triangle-shaped recess, the inboard fixedly connected with square convex block of bearing, the inboard sliding connection of rubber packing ring has the motor shaft, the inboard edge of motor shaft is equipped with square recess, the motor shaft outside fixedly connected with triangle-shaped convex block.

Preferably, the inner side of the square groove is slidably connected with a square bump, and the inner side of the triangular groove is slidably connected with a triangular bump.

Preferably, the triangular grooves inside the rubber washer are arranged in the same shape as the triangular projections outside the motor shaft, and the square grooves inside the motor shaft are arranged in the same shape as the square projections inside the bearing

Preferably, the number of the square protrusions and the triangular grooves is 4, and the number of the square grooves and the number of the triangular protrusions at the outer part of the motor shaft are the same as the number of the square protrusions and the triangular grooves.

Preferably, the bearing is perpendicular to the motor bearing.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the contact area between the motor shaft and the inner side of the bearing can be increased through the arranged rubber gasket, the vibration of the motor bearing during operation can be reduced to a certain extent, the inner side of the bearing is provided with the square bump, the outer edge of the motor shaft is also provided with the square groove with the same shape and position as the square bump, and therefore, the problem that the motor shaft cannot drive the bearing to rotate due to the fact that the bearing and the motor shaft are connected for too long time and are aged can be prevented, and the bearing is very practical.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution:

the utility model provides a silence motor bearing with shock-absorbing function, includes bearing 1, 1 inboard intermediate position department fixedly connected with rubber packing ring 2 of bearing, and 2 inboards of rubber packing ring are equipped with triangle-

shaped recess

3, and 1 inboard fixedly connected with square projection 4 of bearing, 2 inboard sliding connection of rubber packing ring have motor shaft 5, and the inboard edge of motor shaft 5 is equipped with

square recess

7, and 5 outside fixedly connected with triangle-shaped projections 6 of motor shaft.

The inner side of the square groove 7 is connected with a square bump 4 in a sliding way, the inner side of the triangle groove 3 is connected with a triangle bump 6 in a sliding way, the shape arrangement of the triangle groove 3 in the rubber gasket 2 is the same as the shape arrangement of the triangle bump 6 on the outer side of the motor shaft 5, the shape arrangement of the square groove 7 in the motor shaft 5 is the same as the shape arrangement of the square bump 4 on the inner side of the bearing 1, the number of the square bumps 4 and the triangle grooves 3 is 4, the number of the square groove 7 on the inner edge of the motor shaft 5 and the number of the triangle bumps 6 on the outer side are the same as the number of the square bumps 4 and the triangle grooves 3, the bearing 1 and the motor shaft 5 are in a vertical state, the contact area between the motor shaft 5 and the inner side of the bearing 1 can be increased, the vibration generated when the motor bearing 1 operates can be reduced to a certain extent, the inner side of the bearing 1 is provided with the square bump 4, the inner side edge of the motor shaft 5 is also provided with the square groove 7 in the same shape position as the square bump 4, therefore, the bearing 1 and the motor shaft 5 can be prevented from being aged due to overlong connection time, and the motor shaft 5 can not drive the bearing 1 to rotate, so that the bearing is very practical.
