Abstract
The utility model belongs to the technical field of bearing retainers, and particularly relates to a bearing retainer with small starting resistance, which comprises a bearing retainer body, the bearing retainer body comprises a plurality of pockets, spherical grooves are arranged at the bottoms of the pockets, the spherical diameters of the spherical grooves are smaller than the spherical diameters of the pockets and larger than or equal to the spherical diameters of the steel balls, the spherical center of the spherical groove is positioned right below the spherical center of the pocket, the utility model provides a bearing retainer with small starting resistance, the spherical groove is arranged at the center of the bottom in the original pocket, the spherical diameter of the spherical groove is smaller than that of the pocket, the friction area can be reduced by the structure, therefore, the resistance in starting is reduced, the assembly environment with less starting resistance requirements is suitable, in addition, the size of a gap between the pocket and the steel ball is reduced, the wear is not easy, the friction surface is reduced, and the service life of the bearing retainer can be prolonged to a certain extent.
Description
Technical Field
The utility model belongs to the technical field of bearing retainers, and particularly relates to a bearing retainer with small starting resistance.
Background
Cage (i.e., bearing cage, also known as a bearing retainer) refers to a bearing component that partially encases all or part of the rolling elements and moves with them to isolate the rolling elements and generally also guide and retain them within the bearing.
The bearing retainer comprises a plurality of pockets, the pockets are internally provided with rolling bodies (steel balls), the ball diameter of the common pockets is slightly larger than that of the steel balls, and is about 5% larger, so that a certain gap exists between the steel balls and the walls of the pockets, the friction surface is larger, the starting resistance is large, and to some higher installation environments with requirements on the starting resistance, the starting resistance is large, which means that the bearing cannot be used (such as a bearing used on an oil gun, the precision requirement on the starting resistance is very high, the resistance requirement is smaller, and the bearing is mostly an inlet piece at present).
SUMMERY OF THE UTILITY MODEL
The present invention provides a bearing cage with low starting resistance, which can solve the problems pointed out in the background art.
The bearing retainer with small starting resistance comprises a bearing retainer body, wherein the bearing retainer body comprises a plurality of pockets, spherical grooves are arranged at the bottoms of the pockets, the spherical diameters of the spherical grooves are smaller than the spherical diameters of the pockets, the spherical diameters of steel balls are larger than or equal to the spherical diameters of the steel balls, and the spherical centers of the spherical grooves are located under the spherical centers of the pockets.
Preferably, the sphere diameter of the spherical groove is equal to that of the steel ball.
The utility model provides a bearing retainer with small starting resistance, wherein a spherical groove is arranged at the center of the bottom in an original pocket, the spherical diameter of the spherical groove is smaller than that of the pocket, the friction area can be reduced through the structure, so that the resistance during starting is reduced, the bearing retainer can be suitable for an assembly environment with less starting resistance requirements, in addition, the size of a gap between the pocket and a steel ball is reduced, the bearing retainer is not easy to wear, the friction surface is reduced, and the service life of the bearing retainer can be prolonged to a certain extent.

description of reference numerals:
reference numbers in the figures: a bearing cage body 1; a pocket 2; a spherical groove 3; a steel ball 4.
Detailed Description
An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.
Example (b):
as shown in fig. 1-2, a bearing cage with small starting resistance provided by an embodiment of the present invention includes a bearing cage body 1, where the bearing cage body 1 includes a plurality of pockets 2, a spherical groove 3 is disposed at the center of the bottom of each pocket 2, the spherical diameter of the spherical groove 3 is smaller than that of the pocket 2 and greater than or equal to that of a steel ball 4 (rolling element), the spherical center of the spherical groove 3 is located right below the spherical center of the pocket 2, and the spherical diameter of the spherical groove 3 is equal to that of the steel ball 4 (rolling element).
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
