Retaining ring and shaft for securing a component thereon

Claim 2

A retaining apparatus for axially securing a component having a bearing surface onto a shaft, comprising: a shaft having an unthreaded portion and an outer periphery adapted to receive the component for mounting thereon, said shaft defining a first aperture extending radially inwardly from said outer periphery along the unthreaded portion; and a retaining ring including an inner periphery adapted to be assembled on the unthreaded portion of said shaft and a ring body for applying a retaining force against the bearing surface of the component mounted thereon, said retaining ring including a center post extending radially inwardly from said inner periphery for insertion within the aperture of said shaft, wherein said retaining ring further includes a plurality of shoulder segments extending radially inwardly from said inner periphery for defining stabilizing points against which said retaining ring will rest when assembled on said shaft.

Claim 3

The retaining apparatus of claim 2, wherein said shaft defines a plurality of notches formed along said shaft outer periphery on a common plane with said aperture for receiving said shoulder segments.

Claim 4

A retaining apparatus for axially securing a component onto a shaft, comprising: a shaft including a hollow tubular structure having an outer periphery adapted to receive the component for mounting thereon, said shaft defining an aperture extending radially inwardly from said outer periphery and a plurality of notches formed along said shaft outer periphery on a common plane with said aperture; and a retaining ring including an inner periphery adapted to be assembled on said shaft for applying a retaining force against the component mounted thereon, said retaining ring including a center post extending radially inwardly from said inner periphery for insertion within the aperture of said shaft, and further including a plurality of shoulder segments extending radially inwardly from said inner periphery for cooperating with said plurality of notches formed along said shaft outer periphery to define stabilizing points against which said retaining ring will rest when assembled on said shaft; wherein said shaft further includes a core material located within said hollow tubular structure and said core material includes a pocket adapted for receiving therein the center post of said retaining ring.

Claim 5

A retaining apparatus for axially securing a component onto a shaft, comprising: a shaft including a hollow tubular structure having an outer periphery adapted to receive the component for mounting thereon, said shaft defining an aperture extending radially inwardly from said outer periphery and a plurality of notches formed along said shaft outer periphery on a common plane with said aperture; and a retaining ring including an inner periphery adapted to be assembled on said shaft for applying a retaining force against the component mounted thereon, said retaining ring including a center post extending radially inwardly from said inner periphery for insertion within the aperture of said shaft, and further including a plurality of shoulder segments extending radially inwardly from said inner periphery for cooperating with said plurality of notches formed along said shaft outer periphery to define stabilizing points against which said retaining ring will rest when assembled on said shaft; wherein said shaft further includes a core material located within said hollow tubular structure and said core material includes a pocket adapted for receiving therein the center post of said retaining ring.

Claim 6

A retaining ring for axially securing a component having a bearing surface onto an unthreaded portion of a shaft adapted to receive the component for mounting thereon, wherein the shaft defines an aperture extending radially inwardly thereon, said retaining ring comprising: a semi-circular profile having an inner periphery adapted to be assembled onto the unthreaded portion of said shaft and a ring body for applying a retaining force against the bearing surface of the component mounted thereon; and a center post extending radially inwardly form the inner periphery of said retaining ring for insertion within the aperture of the shaft with said retaining ring assembled thereon; and further including a plurality of shoulder segments extending radially inwardly from the inner periphery for defining stabilizing points against which said retaining ring will rest when assembled on the shaft.

Claim 7

A retaining ring for axially securing a component having a bearing surface onto an unthreaded portion of a shaft adapted to receive the component for mounting thereon, wherein the shaft defines an aperture extending radially inwardly thereon, said retaining ring comprising: a semi-circular profile having an inner periphery adapted to be assembled onto the unthreaded portion of said shaft and a ring body for applying a retaining force against the bearing surface of the component mounted thereon; and a center post extending radially inwardly form the inner periphery of said retaining ring for insertion within the aperture of the shaft with said retaining ring assembled thereon; and further including a plurality of shoulder segments extending radially inwardly from the inner periphery for defining stabilizing points against which said retaining ring will rest when assembled on the shaft.
