Problems solved by technology
In rolling bearings, the retaining ring is equivalent to a movable rib, which is used to retain the rollers. The traditional installation method adopts a parallel spigot structure, which is locked on the end face of the inner ring of the bearing by interference fit. , the processing is complicated, the cost is high, and it is easy to cause the inner hole deformation of the inner ring, which affects the product quality

Embodiment Construction
[0008] Such as figure 1 As shown, it includes inner ring 1, outer ring 3, rolling element 2 and retaining ring 4.
[0009] The outer surface of the inner ring 1 and the inner surface of the outer ring 3 are provided with grooves along the circumferential direction. After the inner ring 1 is fitted with the outer ring 3, the grooves of the inner ring 1 and the outer ring 3 form an annular raceway. A rolling body 2 is embedded in the raceway, and the rolling body 2 may be a cylindrical roller or a rolling ball.
[0010] One end face of the inner ring 1 is installed with a retaining ring 4 that limits the position of the rolling element 2. The retaining ring 4 is fastened and installed on the end face of the inner ring 1 through an oblique seam structure. The joint between the retaining ring 4 and the inner ring 1 The structure of the oblique seam is: the end surface of the inner ring 1 is processed into an inverted conical boss, the retaining ring 4 is a structure that can be f...

The invention relates to a bearing with a self-locking check ring, which comprises inner rings, an outer ring and rolling elements, wherein the rolling elements are embedded in a rolling path formed among the inner rings and the outer ring. The innovation point lies in that a check ring for limiting the rolling elements is arranged on the end face of one side of each inner ring, the check ring is buckled on the end surface of each inner ring through an inclined spigot structure, and the check ring is in clearance fit with the inner rings. The bearing has the advantages that the check ring is in clearance fit with the end faces of the inner rings through the inclined spigot structures, locking amounts are formed at connecting parts of the two inner rings and the check ring by using a high point and a low point on an inclined surface to fix the check ring, the check ring is in clearance fit with the inner rings and can rotate to a certain extent on the inner rings, and the adjusting of a ball filling slot is facilitated.
Description
technical field [0001] The invention relates to a bearing, in particular to a bearing with a self-locking retaining ring. Background technique [0002] Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. According to the different friction properties of moving elements, bearings can be divided into two types: rolling bearings and sliding bearings. In rolling bearings, the retaining ring is equivalent to a movable rib, which is used to retain the rollers. The traditional installation method adopts a parallel spigot structure, which is locked on the end face of the inner ring of the bearing by interference fit. , its processing is complicated, the cost is high, and it is easy to cause the deformation of the inner hole of the inner ring, which affects the product quality.
