Description

Technical Field

[0001] The utility model specifically relates to the technical field of bearing retainer splitting, in particular to a high-precision splitting device for a bearing retainer. Background Art

[0002] A cage is a bearing component that partially wraps around all or part of the rolling elements and moves with them to isolate the rolling elements and usually guide the rolling elements and keep them in the bearing.

[0003] When installing the needle roller inside the bearing, it is easy to cause the fit between the needle roller and the retaining frame to be loose. This will cause greater wear between the retaining frame and the needle roller during use, making a harsh sound. During long-term use, it may even cause the bearing retaining frame to break.

[0004] At present, when the conventional bearing cage is being processed, after the processing of the cage window is completed, in order to ensure the rapid installation between the needle roller and the cage, it is necessary to perform a head treatment on the cage. However, the conventional processing equipment does not perform a head treatment on the cage, so that when the needle roller and the cage are installed, there will be a large friction, which will cause defects on the needle roller or the cage during installation, which will greatly reduce the service life of the bearing in long-term use;

[0005] In view of the above situation, we provide a high-precision splitting device for bearing retainers. In this device, the bearing retainer to be processed is placed on the inner side of the end of the placement sleeve, and the bearing retainer is driven to rotate by the rotating shaft inside the placement sleeve. Then, the bearing retainer is effectively split by the processing knife. After the processing is completed, the wear between the needle roller and the bearing retainer is greatly reduced during installation, and the service life of the bearing is effectively improved.
