Abstract

A joint type disc cage of a roller bearing in which a joint is provided at a sheared part of the disc cage so as to fit it into a single-pieced outer or inner race of the roller bearing. Owing to the joint structure of the sheared part of the disc cage, the installation of the disc cage can be easily carried out, and the installed disc cage is maintained in a circular form, so that the function of the disc cage becomes superior, and deformations, abrasions and degradations of the disc cage can be prevented, as well as ensuring the durability and safety of the roller bearing. The disc cage 1 is sheared at one place to form a sheared part 2 which forms two joint end portions 2a and 2b, so as to install the disc cage 1 into an annular installing groove 5 of the outer or inner race 4 and 4a of the roller bearing. The joint end portions 2a and 2b of the sheared part 2 are firmly engagedly coupled together, and therefore, actually the disc cage 1 performs like a non-sheared disc cage.

Claims

1. A joint disc cage of a roller bearing, the disc cage being circular and being sheared so as to install it into an annular installing groove of an inner or outer race of the roller bearing, comprising:

joint end portions of a sheared part of the disc cage, for serving a function of a joint by being firmly engaged together without being loosely moved to left or right or in a radial direction,

wherein said joint end portions of said sheared part of said disc cage form an asymmetric joint structure.

2. A joint disc cage of a roller bearing, the disc cage being circular and being sheared so as to install it into an annular installing groove of an inner or outer race of the roller bearing, comprising:

joint end portions of a sheared part of the disc cage, for serving a function of a joint by being firmly engaged together without being loosely moved to left or right or in a radial direction,

wherein said joint end portions of said sheared part of said disc cage form a J-shaped joint structure.

3. A joint disc cage of a roller bearing, the disc cage being circular and being sheared so as to install it into an annular installing groove of an inner or outer race of the roller bearing, comprising:

joint end portions of a sheared part of the disc cage, for serving a function of a joint by being firmly engaged together without being loosely moved to left or right or in a radial direction,

wherein said joint end portions of said sheared part of said disc cage form an N-shaped joint structure.

4. A joint disc cage of a roller bearing, the disc cage being circular and being sheared so as to install it into an annular installing groove of an inner or outer race of the roller bearing, comprising:

joint end portions of a sheared part of the disc cage, for serving a function of a joint by being firmly engaged together without being loosely moved to left or right or in a radial direction,

wherein said joint end portions of said sheared part of said disc cage form a Q-shaped joint structure.
