Description

Technical Field

[0001] The invention belongs to the technical field of bearings, and in particular relates to an integrated bearing retainer. Background Art

[0002] The integrated bearing cage adopts a self-positioning device through a self-centering overall clamping method, and the workpiece has no interference with the upper end. The positioning accuracy is high and the various technical requirements of the product are controlled;

[0003] Turning: The rough turning process is eliminated and the workpiece is directly processed by CNC machine tools. In order to ensure the shape and position tolerance, special tools are used, and the process is clamped once to ensure the triangle, ellipse, parallelism and smoothness of the workpiece.

[0004] Milling: Eliminate the drilling process. Directly process through the machining center. In order to prevent the workpiece from deforming during the clamping process, the jig adopts an overall clamping method, with no interference on the machining surface and the tool as short as possible. This solves the problem of small diameter tools being easily damaged and workpieces being deformed.

[0005] Subsequent processing: Cancel the manual processing of burrs and replace it with machine tool polishing to reduce deformation and other factors caused during the processing.

[0006] The existing integrated bearing cage has a simple structure and a single function, which can only fix the roller and lacks a locking mechanism. The stability of the roller needs to be further improved. Therefore, we propose an integrated bearing cage. Summary of the invention

[0009] Furthermore, the connection between the arc-shaped clamping plate and the rotating shaft fixing groove is rotatably connected to the self-locking mechanism receiving groove through a fixed shaft.

[0010] Furthermore, the arc-shaped clamping plate and the contact protrusion are an integrated structure.

[0011] Furthermore, the curvature of the arc-shaped clamping plate is consistent with the curvature of the rotating shaft fixing groove.

[0012] Furthermore, the axis of the rotating shaft fixing groove is parallel to the axis of the retaining frame body.

[0013] Furthermore, the retainer body is polished by a machine tool.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
