Abstract
A separator or cage for an antifriction bearing, particularly a ball bearing, wherein the separator starts as a flat strip with an edge strip on one side, and webs projecting laterally from the edge strip and defining pockets for balls between neighboring webs. The strip is bendable at reduced thickness areas along its length to form a ring for installation of the separator between the annular bearing rings. Radially projecting elastic holding noses defined on the surface of the strip at the webs engage at a race of one of the bearing rings and particularly behind a shoulder at one of the races for preventing axial emergence of the separator from between the bearing rings.
Claims14
A separator for the rolling bodies of an antifriction bearing, wherein the separator comprises
- a generally flat strip including webs extending transversely of the strip, adjacent webs defining pockets between them for respective rolling bodies;
- the strip being bendable to form a ring;
- the strip having opposite sides;
- elastic holding noses being defined on at least one of the sides of the strip and projecting out of the strip, the noses being shaped and sized to project radially out of the ring into which the strip is bent, whereby the noses are engageable in one bearing ring of the antifriction bearing for preventing axial direction movement of the separator that has been formed into a ring.
An antifriction bearing comprising an outer ring, an inner ring in the outer ring and spaced radially inward from the outer ring, rolling bodies between the inner and the outer rings, the inner and outer rings having respective races and the rolling bodies rolling on the races;
- a separator for the rolling bodies, the separator comprising
- a generally flat strip including webs extending transversely of the strip, adjacent webs defining pockets between them for respective rolling bodies;
- the the strip being bendable and formed into a ring installed between the inner and outer rings;
- the ring shaped strip having opposite sides;
- elastic holding noses being defined on at least one of the sides of the strip and projecting out of the strip, the noses being shaped and sized to project radially out of the ring into which the strip is bent, whereby the noses are engageable in one of the inner and the outer rings of the bearing for preventing axial direction movement of the separator that has been formed into a ring.
