Description

Technical Field

[0001] The utility model relates to the technical field of rollers, and in particular to a roller with an anti-axial movement structure. Background Art

[0002] As an important component of the bearing, the roller is rotatably connected to the roller frame when in use, and the roller is located between the inner ring and the outer ring of the bearing. When the bearings currently on the market are in use, there is no axial limiting structure between the roller and the inner ring and the outer ring of the bearing. Therefore, when the inner ring of the bearing rotates relative to the outer ring of the bearing, the roller will move axially, which will affect the smoothness of the rotation of the inner ring of the bearing relative to the outer ring of the bearing, and accelerate the wear of the roller, the inner ring of the bearing and the outer ring of the bearing. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a roller with an anti-axial movement structure, which can effectively prevent the roller body from axial movement, thereby improving the smoothness of the rotation of the inner ring of the bearing relative to the outer ring of the bearing.

[0004] The utility model provides a roller with an anti-axial movement structure, comprising a roller body, an annular limiting rib is arranged on the outer peripheral wall of the roller body and in the middle of the axial direction of the roller body, the cross-section of the annular limiting rib is an outwardly convex isosceles triangle structure, and the annular limiting rib is used to roll with a first annular limiting groove located on the outer wall of the bearing inner ring and with a second annular limiting groove located on the inner wall of the bearing outer ring.

[0005] The utility model provides an annular limiting rib on the outer peripheral wall of the roller body and in the middle part of the roller body in the axial direction. The annular limiting rib can roll in cooperation with the first annular limiting groove on the outer wall of the bearing inner ring and the second annular limiting groove on the inner wall of the bearing outer ring. Therefore, when the bearing inner ring rotates relative to the bearing outer ring, the axial movement of the roller body can be effectively avoided, thereby improving the smoothness of the rotation of the bearing inner ring relative to the bearing outer ring. In addition, the wear of the roller body, the bearing inner ring and the bearing outer ring can be effectively avoided and the service life of the bearing can be improved.

[0006] In a possible implementation, annular grooves are provided on both sides of the outer peripheral wall of the roller body in the axial direction of the annular limiting rib. An annular oil storage sponge is embedded in each annular groove, and the oil storage sponge is used to store lubricating oil. The outer peripheral wall of each oil storage sponge coincides with the outer peripheral wall of the roller body. After adopting the above structure, when the roller is applied to the bearing, when the roller rotates with the roller cage and the inner ring of the bearing, the lubricating oil adsorbed in the oil storage sponge can be thrown out under the action of centrifugal force, so as to realize the lubrication of the roller, the roller cage, the inner ring of the bearing and the outer ring of the bearing, and further reduce the rotational damping between the inner ring and the outer ring of the bearing, that is, enable the inner ring of the bearing to rotate more smoothly relative to the outer ring of the bearing, and effectively avoid the wear of the roller, the inner ring of the bearing and the outer ring of the bearing and improve the service life of the bearing. In addition, during the use of the bearing, a grease gun can be used to regularly add lubricating oil to the oil storage sponge.

[0007] In a possible implementation, annular embedding grooves are provided on both sides of each annular groove in the axial direction, and the annular embedding grooves are located at the inner edge of the annular groove; annular protruding parts are provided on both sides of each oil storage sponge in the axial direction, and each annular protruding part is fitted with the annular embedding groove at the corresponding position. After adopting this structure, the annular protruding parts on both sides of the oil storage sponge in the axial direction can be fitted with the annular embedding grooves at the corresponding positions, so as to further realize the radial limit of the oil storage sponge and further improve the firmness of the oil storage sponge and the ball body after assembly.

[0008] In a possible implementation, annular chamfered surfaces are provided at the outer edge and inner edge of the outer end of each annular protruding part, and the annular chamfered surfaces are used to cooperate with the inner wall of the annular embedding groove for guiding so as to facilitate the inner embedding of the annular protruding part into the annular embedding groove. After adopting this structure, when the annular protruding part is fitted with the annular embedding groove, the annular chamfered surface can cooperate with the inner wall of the annular embedding groove for guiding so as to facilitate the inner embedding of the annular protruding part into the annular embedding groove.

[0009] In a possible implementation, the outer peripheral walls at both ends of the roller body in the axial direction form annular rounded surfaces. After the outer peripheral walls at both ends of the roller body in the axial direction are provided as annular rounded surfaces, after the roller body is installed on the roller cage in the bearing, the friction between the two ends of the roller body and the roller cage can be effectively reduced, that is, the rotational damping between the roller body and the roller cage can be reduced, which also enables the rotation of the roller body and the roller cage to be smoother.
