Stabilized backing ring and stabilizing ring therefor

摘要

An axle has a journal to which an antifriction bearing is fitted on an enlarged or dust guard section located beyond the journal, with a fillet leading from the journal up to the enlarged section. A backing ring fits over and against the fillet of the journal and has a counterbore that receives the adjacent end of the enlarged section. A stabilizing ring fits into the counterbore of the backing ring and around the enlarged section of the journal to stabilize the backing ring and thereby reduce radial and circumferential movement between it and the fillet of the journal. The stabilizing ring includes a rigidifying element that fits over the enlarged section of the axle with an interference fit and a more flexible compression member that lies within the counterbore where it exists in a state of compression between the counterbore and the rigidifying element. The stabilizing ring allows some microaxial movement of the backing ring.

主权项

1. In combination with a shaft having a journal to which a bearing is fitted and an enlarged section with a fillet leading from the journal to the enlarged section; the combination comprising:
a backing ring located around the fillet and having a counterbore that receives an end of the enlarged section adjacent to the fillet; and a stabilizing ring for reducing movement between the backing ring and the fillet, the stabilizing ring including:
a rigidifying element located around the enlarged section of the shaft and having an axially directed leg that fits over the enlarged section with an interference fit and a radially directed flange; anda compression member engaging the rigidifying element and a surface of the counterbore in the backing ring, the compression member being in a state of compression between the surface of the counterbore in the backing ring and the rigidifying element, the compression member being formed from a material that is more flexible than the material from which the rigidifying element is formed;wherein the backing ring has a shoulder at an end of the counterbore, and the compression member is located between the flange and the shoulder of the counterbore.
