Abstract
The utility model discloses a high-speed rail bearing retainer locking point structure, which comprises a retainer, wherein the retainer is an annular retainer body, pockets are uniformly distributed on the outer diameter circumferential surface of the annular retainer body, and grooves are also formed on the inner diameter surface of the annular retainer body; pocket bosses are symmetrically arranged at the bottoms of the pockets; the groove is in an isosceles trapezoid shape, and the groove and the pocket boss form a symmetrically distributed locking point structure; and steel balls are arranged in the pocket holes. The utility model ensures that the steel ball is pressed in the pocket hole of the retainer and is not easy to run out by arranging the groove on the retainer and forming a symmetrically distributed locking point structure with the pocket hole boss, thereby leading the outer ring of the bearing, the retainer and the rolling body to be integrated into a whole, leading the bearing not to be scattered under the condition of no inner ring, leading the integral consistency of the bearing to be good, leading the production efficiency to be high and being more suitable for mass production.
Description
Technical Field
The utility model belongs to the technical field of bearings, and mainly relates to a locking point structure of a high-speed rail bearing retainer.
Background
The bearing retainer has the functions of spacing the rolling bodies at equal intervals, preventing the rolling bodies from falling, guiding and driving the rolling bodies to rotate. The outer assembly of the four-point contact ball bearing of the high-speed rail gearbox is required to be not allowed to have the problem of loose sleeves, namely the outer ring, the rolling body and the retainer can not be loosened under the condition that no inner ring exists, so that the rolling body is required to be locked by manually knocking 2 locking points at the circumferentially symmetrical positions of pockets on the inner diameter surface of the retainer. The drawback of manually striking the lock point: the locking amount is too large, and the rolling bodies are not easy to install; the locking amount is too small, and the rolling body is easy to fall off, so that the bearing is loose.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a high-speed rail bearing retainer locking point structure which can well solve the problems of inconsistent locking amount and low processing efficiency of a retainer. In order to realize the purpose of the utility model, the technical scheme is as follows:
a high-speed rail bearing retainer locking point structure comprises a retainer, wherein the retainer is an annular retainer body, pockets are uniformly distributed on the outer diameter circumferential surface of the annular retainer body, and grooves are also formed in the inner diameter surface of the annular retainer body; pocket bosses are symmetrically arranged at the bottoms of the pockets; the groove is in an isosceles trapezoid shape, and the groove and the pocket boss form a symmetrically distributed locking point structure; and steel balls are arranged in the pocket holes.
The diameter of the pocket hole is 0.15mm larger than that of the steel ball.
The groove angle is 135 degrees, the depth is 1.6mm, and the maximum width is 16.4 mm.
The height of the boss of the pocket hole is 0.35mm, and the diameter of the boss of the pocket hole is 0.1mm smaller than that of the steel ball.
The retainer is made of copper.
By implementing the utility model, good use effect is achieved: a locking point structure of a high-speed rail bearing retainer is characterized in that a groove is formed in the retainer and forms a locking point structure which is symmetrically distributed with a pocket boss, so that a steel ball is pressed in a pocket hole of the retainer and is not easy to run, a bearing outer ring, the retainer and a rolling body are integrated, the bearing outer ring, the retainer and the rolling body cannot be separated under the condition of no inner ring, the bearing is good in overall consistency, high in production efficiency and more suitable for mass production.
Drawings
Fig. 1 is a schematic view of the structure of the cage of the present invention.
FIG. 2 is an enlarged schematic view of the pockets of FIG. 1.
Fig. 3 is an overall schematic view of the bearing of the present invention.
In the figure: 1. the bearing comprises a retainer, 2, a pocket, 3, a pocket boss, 4, a groove, 5, a steel ball, 6 and a bearing outer ring.
Detailed Description
The utility model is described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the high-speed rail bearing retainer locking point structure comprises a retainer 1, wherein the retainer 1 is an annular retainer body, pockets 2 are uniformly distributed on the outer diameter circumferential surface of the annular retainer body, and a groove 4 is also formed on the inner diameter surface of the annular retainer body; pocket bosses 3 are symmetrically arranged at the bottoms of the pockets 2; steel balls 5 are arranged in the pockets 2; the groove 4 is in an isosceles trapezoid shape, the groove 4 and the pocket boss 3 form a symmetrically distributed locking point structure, the locking point structure can play a role in positioning the steel ball 5, and the steel ball 5 cannot fall off from the retainer 1 or be loose when the steel ball 5 rotates under the condition that the bearing does not have an inner ring; the diameter of the pocket 2 is 0.15mm larger than that of the steel ball 5, so that the steel ball 5 can be conveniently pressed into the pocket 2; the angle of the groove 4 is 135 degrees, the depth is 1.6mm, the maximum width is 16.4mm, the groove 4 has the function of weight reduction, and the centrifugal force of the retainer 1 in the high-speed operation process can be reduced; the height of the pocket boss 3 is 0.35mm, and the diameter of the pocket boss is 0.1mm smaller than that of the steel ball; the retainer 1 is a copper retainer.
As shown in figure 3, when the bearing is assembled, the retainer 1 is sleeved into the bearing outer ring 6, the steel ball 5 is pressed into the bearing outer ring from the bottom of the pocket 2, the groove 4 and the pocket boss 3 arranged on the retainer 1 form a symmetrically distributed locking point structure, and the locking point structure can play a role in positioning the steel ball 5, so that when the bearing rotates at a high speed, the bearing outer ring 6 plays a role in guiding the retainer 1 to rotate, after the bearing inner ring is removed, the steel ball 5 cannot fall from the retainer 1, the steel ball 5, the retainer 1 and the bearing outer ring 6 are integrated into a whole and cannot be separated, and the bearing is convenient to disassemble and assemble.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the utility model concepts of the present invention are equivalent to or changed within the technical scope of the present invention.
