A rolling element for a cylindrical roller bearing

Abstract

The invention discloses a rolling body for a cylindrical roller bearing. The adopted technical solution includes an intermediate connecting piece, and side connecting pieces are connected to both sides of the intermediate connecting piece, and the connection between the side connecting piece and the intermediate connecting piece A rotating body is rotatably connected between them, a supporting ring is provided at the outer middle position of the intermediate connecting piece, a limit ring is provided on the side of the side connecting piece away from the intermediate connecting piece, and the rotating body corresponds to one side of the supporting ring There is a first wrapping ring on the surface of the bearing, and the inner roller of the bearing of the present invention is hollow, so that the roller can quickly dissipate heat after friction and heat, which protects the bearing roller and prolongs the service life. At the same time, since the rotating body is in contact with the external structure, and the rotating body is set as a detachable structure, after the rotating body is worn out and cannot be used, it can continue to be used only by replacing the rotating body, thereby saving resources.

Description

technical field [0001] The invention relates to the technical field of rolling elements for bearings, in particular to a rolling element for cylindrical roller bearings. Background technique [0002] Bearing rollers are an important part in the bearing. Usually the rollers are installed on the cage. The cage is used to separate the rollers, keep the rollers at equal distances, and distribute the load evenly. When in use, the bearing rollers are in the inner ring of the bearing and the bearing. The rotation between the outer rings realizes the mutual rotation function of the inner ring and the outer ring of the bearing. Because the bearing rollers are always in contact with the cage and the inner and outer rings of the bearing and rub against each other, it is easy to cause the bearing rollers to heat up quickly. The roller is a solid structure, which makes it difficult to dissipate heat after the roller is heated, so that the bearing roller operates at a higher temperature, ...

Problems solved by technology

[0002] The bearing roller is an important part of the bearing. Usually, the roller is installed on the cage. The cage is used to separate the rollers, keep the distance between the rollers equal, and distribute the load evenly. The rotation between the outer rings realizes the function of mutual rotation between the inner ring and the outer ring of the bearing. Since the bearing rollers are always in contact with the cage and the inner and outer rings of the bearing and rub against each other, it is easy to cause the bearing rollers to heat up quickly. At the same time, due to the traditional bearing roller The roller is a solid structure, which makes it difficult to dissipate heat after the roller heats up, so that the bearing roller operates at a higher temperature, thereby shortening the service life of the bearing roller, and most of the current rollers are integrated. After the roller is worn out, the whole roller will be discarded, resulting in a waste of resources
