Abstract

An angular ball bearing having an outer ring, a cage mounted in the outer ring and formed at equal circumferential intervals with pockets and balls received in the pockets, and an inner ring mounted in the cage. The cage is formed on the surface of the pockets with projections to prevent the balls from coming out of the pockets. When the balls are in abutment with the projections, the diameter of the circumscribed circle of the balls is equal to or smaller than the internal diameter of the outer ring.

To assemble the angular ball bearing, the balls are set in the pockets in the cage, a resilient member having substantially the same external diameter as that of the inner ring and the resilient member is pushed out with the inner ring in an axial direction to fit the inner ring inside the balls.

Claims

1. An angular ball bearing comprising an outer ring having an inner peripheral surface, a ball rolling surface at a central portion of said inner peripheral surface and having a diameter larger than the diameter of said inner peripheral surface of said outer ring, a cage mounted inward of said outer ring and formed at equal circumferential intervals with pockets, an inner ring mounted inward of said cage, said cage having an outer peripheral surface guided by said outer ring, and balls received in said pockets, said cage being formed on the inner surface of said pockets with projections extending outwardly of said cage and toward said inner ring for preventing said balls from coming out of said pockets at said inner surface of said pockets in said cage when said inner ring is removed from said cage, the diameter of the circle circumscribed by said balls being no greater than the diameter of said inner peripheral surface of said outer ring when said balls are in abutment contact with said projections, said balls being out of abutment contact with said projections when said balls are in said pockets in said cage and said outer ring and said inner ring are mounted on said cage and said balls in said pockets in said cage.
