Abstract
Abstract The invention contemplates a bearing-roller retainer of machined ductile material utilizing local deformation of roller-pocket sides to develop a unit-handling assembled relation with inserted rolls. The rolls are of the recessed-end variety, and retainer material is displaced into retaining relation with the recessed ends of the rollers. The nature of the displacement is such as to achieve a retained assembly of rollers while avoiding any upset to the inherent running balance and dimensional accuracy of the machined retainer structure.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
A roller-bearing retainer comprising an annulus of ductile material with plural angularly spaced roller-receiving pockets, each pocket extending radially through said annulus and confined at axial ends by end walls forming part of said annulus, each such wall having a recess local to the central region of the wall at its adjacent pocket and open axially outwardly, each such wall recess terminating short of the axially inner limit of the wall, the depth of the recess in terms of the remaining wall thickness being such that the end wall opposite localized central region may be incrementally displaced substantially to the exclusion of the remainder of the wall for retaining a recessed roller in the pocket.
Claim 2
Dependent Claim
115 words
A roller-bearing retainer comprising an annulus of ductile material with plural angularly spaced roller-receiving pockets, each pocket extending radially through said annulus and confined at axial ends by end walls forming part of said annulus, each such wall having a recess local to the central region of the wall at its adjacent pocket and open axially outwardly, each such wall recess terminating short of the axially inner limit of the wall, the depth of the recess in terms of the remaining wall thickness being such that the end wall opposite localized central region may be incrementally displaced substantially to the exclusion of the remainder of the wall for retaining a recessed roller in the pocket.
Claim 3
Dependent Claim
167 words
As an article of manufacture, a unit-handling assembly comprising a roller-bearing retainer with rollers retained therein, each of said rollers having a central recess at each end thereof, said retainer being an integral one-piece annulus with plural angularly spaced roller-receiving pockets, each pocket extending radially through said annulus and confined at axial ends by end walls forming part of said annulus, each such wall having a recess local to the central region of the wall at its adjacent pocket and open axially outwardly, the depth of the recess being such that the remaining wall thickness is small compared to the overall wall thickness, thereby defining a relatively thin end-wall portion adjacent each roller end, and a local axially inward projection integral with each said relatively thin end-wall portion, each such projection extending into loose retaining relation with the adjacent roller end recess, whereby said rollers are radially retained in unit-handling relation with said retainer solely by the action of the projections of said relatively thin end-wall portions.
Claim 4
Dependent Claim
167 words
As an article of manufacture, a unit-handling assembly comprising a roller-bearing retainer with rollers retained therein, each of said rollers having a central recess at each end thereof, said retainer being an integral one-piece annulus with plural angularly spaced roller-receiving pockets, each pocket extending radially through said annulus and confined at axial ends by end walls forming part of said annulus, each such wall having a recess local to the central region of the wall at its adjacent pocket and open axially outwardly, the depth of the recess being such that the remaining wall thickness is small compared to the overall wall thickness, thereby defining a relatively thin end-wall portion adjacent each roller end, and a local axially inward projection integral with each said relatively thin end-wall portion, each such projection extending into loose retaining relation with the adjacent roller end recess, whereby said rollers are radially retained in unit-handling relation with said retainer solely by the action of the projections of said relatively thin end-wall portions.
