Abstract
The utility model discloses a cage pocket structure for a high-speed bearing, which comprises a cage and a pocket arranged in the cage; the radius of a circular arc in a longitudinal section view of the pocket passing through the center is R, and the radius of a rolling body in the pocket is R, wherein
The pocket structure in the utility model can form an effective wedge-shaped space between the retainer and the rolling body, and the wedge-shaped space can keep lubricating grease in the pocket from running off, so that the lubrication in the rolling body is more sufficient, thereby improving the high-speed performance of the bearing; and the pocket structure solves the difficult problem of difficult demoulding in the production of straight pocketsThe development cost of the die can be reduced, and the production efficiency is improved.
Description
Technical Field
The utility model relates to a bearing field, more specifically says that it relates to a cage pocket structure that high-speed bearing used.
Background
The cage acts to evenly space the rolling elements in the rolling bearing, but it has a significant impact on the performance of the bearing, such as life, vibration, noise, rotational flexibility, etc. In the existing cage, the shape of a pocket is roughly two types: straight pockets and spherical pockets. The cage with the straight pocket hole can not realize the guiding of the cage by a steel ball, needs to be guided by a flange, is limited in the aspects of high speed, lubrication, low noise and the like, is difficult to demould and has high manufacturing cost; however, the existing spherical pocket retainer also has the defects in structure, as shown in figure 1, because the pocket of the retainer 1 is spherical, the shape of the wall surface of the whole spherical pocket is matched with that of the rolling body 2, namely the radius of the spherical pocket is approximately equal to that of the rolling body; the clearance between the wall surface of the pocket hole and the rolling body is uniform and very small, and when the bearing is operated under the condition of high speed or ultrahigh speed, the retainer can not effectively prevent the lubricating grease in the bearing from losing due to centrifugal force, so that poor lubrication occurs in the bearing, and the high-speed performance of the bearing is influenced.
SUMMERY OF THE UTILITY MODEL
A primary object of the present invention is to provide a cage pocket structure for a high-speed bearing, which can prevent the loss of grease in the pocket, so that the lubrication of the rolling elements is more sufficient.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a cage pocket structure for a high-speed bearing comprises a cage, a pocket arranged in the cage; the radius of a circular arc in a longitudinal section view of the pocket passing through the center is R, and the radius of a rolling body in the pocket is R, wherein
Through the technical scheme, the pocket structure in the utility model can form an effective wedge-shaped space between the retainer and the rolling body, and the wedge-shaped space can keep lubricating grease in the pocket from running off, so that the lubrication in the rolling body is more sufficient, and the high-speed performance of the bearing is improved; and the difficult problem of drawing of patterns difficulty in the production of straight pocket has been solved to this pocket structure, can reduce mould research and development cost, improves production efficiency.
In a further technical scheme, the method comprises the following steps of,
the utility model has the advantages that: the pocket structure in the utility model can form an effective wedge-shaped space between the retainer and the rolling body, and the wedge-shaped space can keep lubricating grease in the pocket from running off, so that the lubrication in the rolling body is more sufficient, thereby improving the high-speed performance of the bearing; and the difficult problem of drawing of patterns difficulty in the production of straight pocket has been solved to this pocket structure, can reduce mould research and development cost, improves production efficiency.

FIG. 1 is a cross-sectional view of a prior art pocket in the shape of a sphere;
fig. 2 is a cross-sectional view of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
As shown in fig. 2, a cage pocket structure for a high-speed bearing includes a cage 1, a pocket 101 provided in the cage 1; the radius of the arc in the over-center longitudinal section of the pocket 101 is R, and the radius of the rolling element in the pocket 101 is R, wherein
In this example
The pocket 101 structure of the utility model can form an effective wedge-shaped space 3 between the retainer 1 and the rolling body, and the wedge-shaped space 3 can keep the lubricating grease in the pocket 101 from running off, so that the lubrication in the rolling body is more sufficient, thereby improving the high-speed performance of the bearing; and this pocket 101 structure has solved the difficult problem of drawing of patterns difficulty in the production of straight pocket 101, can reduce mould research and development cost, improves production efficiency.
In addition, a left oil storage tank 11 is arranged on the left inner side wall of the pocket 101 near the openings at the upper end and the lower end, and a right oil storage tank 12 is arranged on the right inner side wall of the pocket 101 near the openings at the upper end and the lower end; in the setting, the left oil storage tank 11 and the right oil storage tank 12 are positioned at the wedge-shaped space 3, so that the storage of lubricating grease can be realized, and the lubrication of the bearing is ensured.
The retainer 1 is internally provided with a left oil hole 13 for communicating the two left oil storage grooves 11 and a right oil hole 14 for communicating the two right oil storage grooves 12, and the arrangement can ensure the complementation of grease in the two left oil storage grooves 11 and the complementation of grease in the right oil storage groove 12.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
