Abstract
The invention relates to a single-row roller bearing cage. The single-row roller bearing cage solves the technical problem that an existing bearing cage is poor in stability. The single-row roller bearing cage comprises a cylindrical cage body. A plurality of strip-shaped retaining holes which extend in the axial direction of the cage body are formed in the circumferential direction of the cage body, the width of the portion, from the outer side of the cage body to the inner side of the cage body, of each strip-shaped retaining hole is gradually reduced, and arc-shaped inclined surfaces which are arranged in an inclined and face-to-face mode are arranged on the two sides of each strip-shaped retaining hole respectively. Limiting strips are arranged outside the two sides of each strip-shaped retaining hole, and are in an arc shape, and one of the two limiting strips on the outer sides of each strip-shaped retaining hole is detachably connected with the cage body through an insertion connecting structure, or the two limiting strips on the outer sides of each strip-shaped retaining hole are detachably connected with the cage body through insertion connecting structures. The single-row roller bearing cage has the advantages that the structure is simple, the stability is high, installation of rollers is facilitated, the lubrication degree is high, abrasion cannot easily happen between roller bodies and the cage, and the service life is long.
