A kind of bearing retainer and its production method

Abstract

The invention provides a technical solution of a bearing retainer and its production method. The bearing retainer includes a clawless part and a clawed part matched with the clawless part. The riveted claws are clamped and positioned on the inner side of the plane without claws. The production steps are: (1) stamping the material strip with claws, so that the raw material body with claws and the Separating the tape to obtain the raw material with claws; (2) stamping the raw material with claws obtained in step (1) to obtain the claws; (3) combining the non-clawed part with the claws obtained in step (2) Assembly: The riveted claws with claws are bent twice so that the claws and non-claws are clamped to obtain a bearing retainer. In this scheme, the upper part without claws and the lower part with claws are riveted and fixed by riveting claws to form a bearing retainer, and the riveting claws are located on the inner side of the lower plane of the lower part with claws, which has the advantages of saving material tape, stable production and assembly quality advantage.

Description

technical field [0001] The invention relates to a cage, especially a bearing cage and a production method thereof. Background technique [0002] Bearings are commonly used parts in the machinery industry. Its basic components are inner rings, outer rings, rolling elements and cages. The cages are used as rolling supports between the inner rings and outer rings to keep the rolling elements evenly distributed around the circumference of the rings. . [0003] Small V-shaped bearings generally use a claw retainer, which is divided into two parts, and the two parts are fixed by claws. Figure 5 ) to obtain the corresponding raw material body with claws, stamping the raw material body with claws and then cooperating with the non-claw parts to obtain the bearing retainer. The claws of the bearing retainer used in the prior art are located on the outside of the retainer. The disadvantages of this bearing retainer are: [0004] (1) The unfolded shape of the material body with claws...

AI Technical Summary

Problems solved by technology

[0004] (1) The unfolded shape of the material body with claws on the material belt is relatively large, which wastes materials and is not conducive to the purpose of energy saving and environmental protection;

[0005] (2) The material body with claws and the strip are connected by two claws with claws. In this way, when stamping, the entire strip will shrink, resulting in skewed deformation of the claws. Influence on the assembly of bearings
