Description

Wear-resistant bearing

Technical Field

The utility model relates to the field of bearings, in particular to a wear-resistant bearing.

Background

The bearings are mechanical elements for supporting a rotating shaft, reducing friction and wear, improving mechanical efficiency, they are generally made of metal or plastic, and are divided into an inner ring, an outer ring, and rolling bodies, which roll between the inner and outer rings, can reduce friction and wear while bearing load, and are various in variety, and can be divided into various types according to their structures and application scenarios, such as deep groove ball bearings, cylindrical roller bearings, tapered roller bearings, angular contact bearings, thrust bearings, etc., and in various machines, the bearings are widely used in various rotating mechanisms, such as motors, pumps, compressors, gear boxes, etc., and by using the bearings, reliability, stability, and mechanical efficiency of the machine can be improved;

In order to prolong the service time of the bearing in the prior art, measures such as solid engine oil are generally added into the bearing to reduce the friction force between the ball bearing and the shaft body and between the ball bearing and the shaft sleeve, but the existing bearing cannot well store the solid engine oil, if additional equipment is used for storing the solid engine oil or continuously adding lubrication, the volume of the bearing can be increased, and the flexibility of bearing installation is affected.

Disclosure of utility model

The present utility model provides a wear bearing that overcomes the deficiencies described in the background.

The technical scheme adopted for solving the technical problems is as follows:

The wear-resistant bearing comprises a shaft sleeve, a shaft body and a rolling element, wherein the rolling element is sleeved outside the shaft body, an annular groove is formed between the shaft sleeve and the shaft body, and the rolling element is arranged in the annular groove;

The rolling piece comprises balls, a filling cloth piece and a fixing piece, wherein the balls are annularly arranged in the annular groove, the outer diameter of each ball is smaller than the width of the section of the annular groove, a gap is reserved between each ball and the inner wall of the annular groove, and the filling cloth piece and the fixing piece are filled in the gap;

The filling cloth piece is sleeved outside the fixing piece, and the filling cloth piece and the fixing piece are respectively propped against the ball.

A preferred technical scheme is as follows: the surface annular array of the filling cloth pieces is multiple, and when the filling cloth pieces are filled in the gaps and abutted against the surfaces of the balls, the balls are embedded into the filling cloth pieces.

A preferred technical scheme is as follows: the surface of the fixing piece is provided with a plurality of grooves in an array manner, and every two adjacent grooves are communicated through a communication groove;

the ball is arranged in the groove.

A preferred technical scheme is as follows: the filling cloth piece is propped against the outer sides of all the balls, and the fixing piece is propped against the lower parts of the inner sides of all the balls.

Compared with the background technology, the technical proposal has the following advantages:

The bearing of the utility model limits the displacement of the ball mainly through the filling cloth piece and the fixing piece, so that the bearing can only roll in situ, in order to sufficiently reduce the friction force between the rolling piece and the shaft sleeve as well as between the shaft body and the rolling piece, solid lubricating oil can be extruded between the shaft body and the rolling piece, and the filling cloth piece and the fixing piece can sufficiently infiltrate the lubricating oil, and under the condition that the filling cloth piece and the fixing piece are embedded into the annular groove, the outflow of the solid lubricating oil can be effectively reduced.
