Abstract
Abstract A compact resilient retainer ring for axially retaining a roller slidably and rotatably mounted on a spindle by needle rollers, and the needle rollers. The ring is U-shaped in radial crosssection and has a radially inner wall and a radially outer wall with a bowed connecting portion. The inner wall is adapted to resiliently bear against a groove machined in the outer surface of the spindle. The outer wall is adapted to retain the roller and the connecting portion is adapted to retain the needle rollers. The inner wall is provided with corrugations, the radially innermost portions of the corrugations are tangent to a circle having a diameter less than that of the spindle. The outer wall may also be provided with such corrugations, or with a flared frusto-conical outer portion, or it may be simply a plain cylindrical wall.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
104 words
A resilient retainer ring for axially retaining at least one member for rotation on a spindle member having a groove in its outer surface, said retainer ring being generally U-shaped in cross-section and having a radially inner wall adapted to be clicked into and resiliently bear against the groove in the spindle member and a radially outer wall, the radially inner wall having corrugations, formed therealong, the mean circle of the corrugations being parallel to the general plane of the retainer ring, the radially innermost portions of the corrugations being tangent to a circle having a diameter less than that of the spindle member.
Claim 2
Dependent Claim
104 words
A resilient retainer ring for axially retaining at least one member for rotation on a spindle member having a groove in its outer surface, said retainer ring being generally U-shaped in cross-section and having a radially inner wall adapted to be clicked into and resiliently bear against the groove in the spindle member and a radially outer wall, the radially inner wall having corrugations, formed therealong, the mean circle of the corrugations being parallel to the general plane of the retainer ring, the radially innermost portions of the corrugations being tangent to a circle having a diameter less than that of the spindle member.
Claim 3
Dependent Claim
35 words
A retainer ring according to claim 1, wherein the radially outer wall is adapted to axially retain said one member which is an annular roller adapted to rotate on and slide along the spindle member.
Claim 4
Dependent Claim
