Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to an anti-slip bearing. Background Technique

[0002] A bearing is a component that plays a role in fixing and reducing the load friction coefficient during the mechanical transmission process. It can also be said that when other machine parts generate relative motion to each other on the shaft, it is used to reduce the friction coefficient during the power transmission process and keep the shaft center position fixed. A bearing is a very important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the mechanical load friction coefficient during the equipment transmission process, and ensure its rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings.

[0003] Currently, during the use of bearings, since most existing bearings rely on the interference fit relationship between the bearing outer ring and the bearing housing to fix the bearing in the bearing housing, and both the outer ring and the inner ring of the bearing are made of metal materials and their surfaces are polished, the overall anti-slip property of the bearing outer ring is relatively low, resulting in the phenomenon that the bearing outer ring is prone to running off the track, which is not convenient for use and reduces the use efficiency of the bearing. For this reason, we propose an anti-slip bearing. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-slip bearing to solve the problem proposed in the above background technique that most existing bearings rely on the interference fit relationship between the bearing outer ring and the bearing housing to fix the bearing in the bearing housing, and both the outer ring and the inner ring of the bearing are made of metal materials and their surfaces are polished, resulting in the overall low anti-slip property of the bearing outer ring, the phenomenon that the bearing outer ring is prone to running off the track, which is not convenient for use and reduces the use efficiency of the bearing.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-slip bearing, including a bearing outer ring body and a bearing inner ring body. The bearing inner ring body is located in the inner cavity of the bearing outer ring body. A first card slot is opened in the inner cavity of the bearing outer ring body. Annular grooves are opened on the front and rear sides of the outer side wall of the bearing outer ring body. An installation groove is opened in the middle of the outer side wall of the bearing outer ring body, and the installation groove is annularly distributed. An elastic member is fixedly connected to the inner cavity of the installation groove. The end of the elastic member is fixedly connected with a limiting block, and the limiting block is slidably connected in the inner cavity of the installation groove. An extension block is fixedly connected to the outer side wall of the limiting block. An anti-slip pad is fixedly connected to the outer side wall of the extension block. A second card slot is opened in the middle of the outer side wall of the bearing inner ring body.

[0006] As a further description of the above technical solution:

[0007] The inner cavity of the annular groove is clamped with an anti-slip ring, and both the anti-slip ring and the anti-slip pad are made of rubber material.

[0008] As a further description of the above technical solution:

[0009] The outer side wall of the anti-slip ring is provided with a first anti-slip groove, and the first anti-slip groove is annularly distributed.

[0010] As a further description of the above technical solution:

[0011] The outer side wall of the anti-slip pad is provided with a second anti-slip groove, and the second anti-slip grooves are arranged in sequence from left to right.

[0012] As a further description of the above technical solution:

[0013] A ball is slidably connected between the inner cavity of the second card slot and the inner cavity of the first card slot, and the balls are annularly distributed.

[0014] As a further description of the above technical solution:

[0015] A positioning ring is clamped between the front sides and the rear sides of the outer side walls of the balls, and the positioning ring is made of stainless steel material.

[0016] Compared with the prior art, the beneficial effect of the present utility model is as follows: for this anti-slip bearing, the surface friction coefficient of the outer ring body of the bearing is increased by clamping an anti-slip ring inside the annular groove. Then, after the outer ring body of the bearing is connected to the bearing seat, the inner wall of the bearing seat presses the extension block, driving the extension block to cooperate with the limit block to compress the elastic member. The rebounding force after the elastic member is compressed, together with the limit block, drives the extension block and the anti-slip pad to be in close contact with the inner wall of the bearing seat. And the anti-slip property of the outer ring body of the bearing is improved by the friction generated when the anti-slip pad contacts the inside of the bearing seat, making the overall anti-slip property of the outer ring of the bearing high, not prone to running ring phenomenon, convenient to use, and improving the use efficiency of the bearing.

Annular grooves 120 are formed on the front and rear sides of the outer side wall of the outer bearing ring body 100. The annular grooves 120 are used to provide an installation space for the anti-slip ring 130. An installation groove 150 is formed in the middle of the outer side wall of the outer bearing ring body 100, and the installation groove 150 is annularly distributed. The installation groove 150 is used to provide an installation space for the elastic member 160. An elastic member 160 is fixedly connected to the inner cavity of the installation groove 150.
