Problems solved by technology

This connection structure has the following disadvantages: 1. When the rivet is not perpendicular to the plane, the frame will move radially, which will easily cause the rivet to fall off; 2. There will be a gap between the two frames, which will generate noise during work; 3. , The use of rivets increases the production cost

Embodiment Construction

[0014] In order to clearly illustrate the technical characteristics of this solution, the following will describe this solution through specific implementation modes and in conjunction with the accompanying drawings.

[0015] A deep groove ball bearing cage, such as figure 1 , figure 2 and image 3 As shown, it includes a frame body I8 and a frame body II 9 that are docked with each other. The frame body I 8 and the frame body II 9 are composed of a ball pocket 1 and a plane 2 that connects each ball pocket 1 into a ring shape. The frame body I 8 Protrusions 3 are provided on at least three planes 2 above, and positioning holes 4 corresponding to the protrusions 3 are provided on the corresponding planes 2 of the frame body II 9 . After the protrusion 3 passes through the positioning hole 4, the end of the protrusion 3 is welded to the frame body II 9 together.

[0016] The contour line of the inner surface of the single ball bag 1 on the frame body I 8 and the frame body ...

Abstract

The invention relates to a deep groove ball bearing retainer and a bearing using the retainer. The retainer comprises a retainer body I and a retainer body II which are mutually butted, the retainer body I and the retainer body II consist of ball pockets and planes for connecting the ball pockets into ring shape, at least three planes on the retainer body I are provided with protrusions, the corresponding planes of the retainer body II are provided with positioning holes corresponding to the protrusions, and the passing-out parts of the protrusions are welded with the retainer body II together after the protrusions pass through the positioning holes. The bearing retainer with the structure can realize firm welding between the retainer body I and the retainer body II, avoid rivet connection, reduce the production cost and noise, and avoid radial wandering of the retainer body I and / or the retainer body II and release of rivets.

Description

Technical field: [0001] The invention relates to a bearing cage, in particular to a deep groove ball bearing cage and a bearing using the cage. Background technique: [0002] In the current general-purpose deep groove ball bearing cage, the two butted frames are fixedly connected by rivets. This connection structure has the following disadvantages: 1. When the rivet is not perpendicular to the plane, the frame will move radially, which will easily cause the rivet to fall off; 2. There will be a gap between the two frames, which will generate noise during work; 3. , The use of rivets increases production costs. Here it is the weak point that existing technology exists. Invention content: [0003] The purpose of the present invention is to address the shortcomings of the prior art, and to provide a deep groove ball bearing cage that enables two cages to be firmly connected and a bearing using the cage. The cage can avoid radial play of the cage. The movement and rivets fa...
