Description

Bearing with ceramic retainer

Technical Field

The invention relates to a bearing, in particular to a bearing with a ceramic retainer.

Background

The Bearing (Bearing) is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient (friction coefficient) in its motion process, and guarantee its gyration precision (accuracy).

Most of the traditional bearings are made of all-metal or plastic, the weight of all-metal bearings is heavier, the bearings are easy to conduct electricity, and the bearings are not easy to use on some electrified machines, and the bearings made of plastic are easy to deform due to heat, so that the normal use of the bearings is affected. To this end, we propose a bearing with a ceramic cage.

Disclosure of Invention

The invention mainly aims to provide a bearing with a ceramic retainer, which can effectively solve the problems in the background technology.

In order to achieve the purpose, the invention adopts the technical scheme that:

the utility model provides a bearing with ceramic holder, includes inner collar, ceramic holder, outer collar and ball, the ball is located between inner collar and the ceramic holder, outer collar buckle is in ceramic holder surface, a sliding tray and No. two sliding trays have all been seted up on inner collar and ceramic holder surface, the ball buckles respectively in a sliding tray and No. two inside the sliding tray.

Further, a rubber sleeve is adhered to the inner wall of the inner shaft ring, and a sealing cover is connected between the inner shaft ring and the outer shaft ring in a buckling mode.

Further, the inside metal reinforcing strip that inlays of ceramic holder, and the metal reinforcing strip is located sliding tray and No. two sliding tray one sides, it has the shock attenuation cushion to fill between ceramic holder and the outer collar.

Further, outer collar surface has been seted up and has been annotated the liquid hole, annotate the inside intercommunication each other of liquid hole and a sliding tray and No. two sliding trays, annotate the inside buckle of liquid hole and be connected with the stopper cap.

Compared with the prior art, the invention has the following beneficial effects:

1. this kind of bearing with ceramic holder can avoid article and the condition that the bearing links up the department and appears wearing and tearing and skidding through the rubber sleeve of interior axle ring inner wall adhesion, through a sliding tray and No. two sliding trays that interior axle ring and ceramic holder surface were seted up to and the ball that sliding tray and No. two sliding tray inside thread slipping connect, prolong the life of whole bearing, avoid leading to the unable normal use condition of whole bearing to appear because of the ball damages in the single spout.

2. This kind of bearing with ceramic holder has strengthened ceramic holder's firmness through the inside metal reinforcing strip of inlaying of ceramic holder, avoids leading to the cracked condition of ceramic holder to appear very fast because of the bearing rotates, and the setting of ceramic holder has also effectively stopped dredging of electric power, avoids appearing because of the bearing produces electrically conductive condition, and the sealed cowling of buckle connection between interior collar and the outer collar can effectively avoid external dust to get into the life of influence bearing in the bearing.

3. This kind of bearing with ceramic holder passes through the shock attenuation cushion of filling between porcelain holder and the outer collar, can effectively avoid appearing because of the condition that external atress extrusion leads to outer collar deformation crushing porcelain holder, has seted up through outer collar surface simultaneously and has annotated the liquid hole, and the emollient that does benefit to the inside interpolation of bearing is maintained the bearing, prolongs the life of bearing.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

As shown in fig. 1 to 4, a bearing with a ceramic holder includes an inner collar 1, a ceramic holder 2, an outer collar 7 and balls 12, where the balls 12 are located between the inner collar 1 and the ceramic holder 2, the outer collar 7 is fastened to the surface of the ceramic holder 2, the surfaces of the inner collar 1 and the ceramic holder 2 are both provided with a first sliding groove 5 and a second sliding groove 6, and the balls 12 are respectively fastened inside the first sliding groove 5 and the second sliding groove 6.

Wherein, the inner wall of the inner shaft ring 1 is adhered with a rubber sleeve 8, and a sealing cover 3 is connected between the inner shaft ring 1 and the outer shaft ring 7 in a buckling manner.

Wherein, 2 inside inlays of ceramic holder have metal reinforcing strip 11, and metal reinforcing strip 11 is located sliding tray 5 and No. two sliding tray 6 one sides, it has shock attenuation cushion 4 to fill between ceramic holder 2 and outer collar 7.

The surface of the outer shaft collar 7 is provided with a liquid injection hole 9, the liquid injection hole 9 is communicated with the insides of the first sliding groove 5 and the second sliding groove 6, and a plug cap 10 is connected to the inside of the liquid injection hole 9 in a buckling mode.

It should be noted that, the invention is a bearing with a ceramic retainer, when in use, the whole bearing is fixed on an object to be used, the abrasion and slipping of the joint of the object and the bearing can be avoided by the rubber sleeve 8 adhered to the inner wall of the inner shaft collar 1, the first sliding groove 5 and the second sliding groove 6 arranged on the surfaces of the inner shaft collar 1 and the ceramic retainer 2 and the balls 12 in the first sliding groove 5 and the second sliding groove 6 are in sliding and buckling connection, the service life of the whole bearing is prolonged, the phenomenon that the whole bearing cannot be normally used due to the damage of the balls 12 in the single sliding groove is avoided, the firmness of the ceramic retainer 2 is enhanced by the metal reinforcing strip 11 embedded in the ceramic retainer 2, the phenomenon that the ceramic retainer 2 is cracked due to the fast rotation of the bearing is avoided, and the arrangement of the ceramic retainer 2 also effectively prevents the dredging of electric power, avoid appearing because of the electrically conductive condition of bearing production, through the cushion 4 that absorbs shock of filling between porcelain holder 2 and outer collar 7, can effectively avoid appearing because of the condition that external atress extrusion leads to outer collar 7 to warp crushing porcelain holder 2.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
