An Improved Bearing Annular Snap-Lock Cage Structure

Abstract

The present invention relates to an improved ring-shaped snap-lock cage structure for bearings, including: a cage, a pocket, a lock, a guiding curved surface, a snap-lock beam, and a rolling body, wherein the cage is an integrally formed annular cylindrical Structural frame, the circumference of the cage is provided with pocket holes, and a spring lock beam is provided between every two pocket hole openings, and an arc-shaped guide surface is provided at the joint between the spring lock beam and the pocket hole opening, and the pocket hole and the guide surface There is a lock opening with a lock rolling body between them, and the rolling body is placed in the pocket hole. In the present invention, the guiding slope is changed into a guiding curved surface, which is convenient for processing, easy to control the size of the locking port, and improves the production efficiency.

Description

technical field [0001] The invention relates to a bearing, in particular to an improved structure of an annular snap-lock cage for the bearing. Background technique [0002] The structure of bearing annular snap-lock cage is a common bearing cage structure at this stage, please refer to Figure 1A , Figure 1B and Figure 1C As shown, they are respectively the schematic diagram of the ring-shaped snap lock cage structure of the bearing in the prior art, the expanded partial structure section view and the partial enlarged view. °) slope. When machining the cage, the guide bevel 7 is milled out on a CNC drilling and milling machine, and the production efficiency is low. Because the spring lock beam 5 plays an elastic role, its beam is not easy to be wide, so when milling the guide slope 7 on the side of the spring lock beam 5, under the action of a large radial cutting force on the drilling and milling machine, an elastic let-off of the knife will occur, resulting in Lock ...
