Abstract
Abstract A system for securing cylindrical members such as a roller bearing on a shaft or in the bore of a sleeve bushing wherein the cylindrical members are formed so that a portion of one abuts the other. The corresponding surface of one of the cylindrical members is provided with an annular wedge shaped slot narrowing outwardly toward the face end of the member. A retaining member formed as an arcuate piece having at least one axially extending wedge secured thereto is positioned in said slot, to forcibly act on the members and hold them secure with respect to each other.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A bearing adapted to be secured on a cylindrical member such as a shaft or in the bore of a sleeve bushing, comprising an inner race member, an outer race member and a plurality of roller means located therebetween, one of the surfaces of one of said race members having a cylindrical portion adapted to abuttingly engage the respective cylindrical member and an annular axially tapered slot formed therein radially narrowing outwardly from said abutting portion toward the outer axial end, and retaining means comprising an arcuate section member having a width less than the axial length of said slot, an internal diameter conforming to that abutting portion and at least one axially extending wedge shaped tongue secured thereto, said axially extending wedge tongue conforming in its cross-section to the taper of said slot and being compressively positioned in said slot, and having a width substantially less than that of said arcuate section member,
Claim 2
Dependent Claim
154 words
A bearing adapted to be secured on a cylindrical member such as a shaft or in the bore of a sleeve bushing, comprising an inner race member, an outer race member and a plurality of roller means located therebetween, one of the surfaces of one of said race members having a cylindrical portion adapted to abuttingly engage the respective cylindrical member and an annular axially tapered slot formed therein radially narrowing outwardly from said abutting portion toward the outer axial end, and retaining means comprising an arcuate section member having a width less than the axial length of said slot, an internal diameter conforming to that abutting portion and at least one axially extending wedge shaped tongue secured thereto, said axially extending wedge tongue conforming in its cross-section to the taper of said slot and being compressively positioned in said slot, and having a width substantially less than that of said arcuate section member,
Claim 3
Dependent Claim
44 words
The bearing according to claim 1 wherein said cylindrical member is the race ring of a roller bearing and said annular slot is formed on the outer surface thereof and extends axially from the plane of rotation of the bearing to the frontal end.
Claim 4
Dependent Claim
23 words
The bearing according to claim 1 including a plurality of extending wedges secured to said arcuate section member uniformly arranged about its circumference.
Claim 5
Dependent Claim
35 words
The bearing according to claim 1 wherein said wedge is provided with at least one axially extending tongue having a threaded outer surface and a threaded ring adapted to be located over said threaded surface.
Claim 6
Dependent Claim
21 words
The bearing according to claim 1 wherein said arcuate member and said extending wedges are formed of a hard resilient material.
Claim 7
Dependent Claim
27 words
The bearing according to claim 1 wherein said arcuate member is at least semi-circular in extent and is resiliently force fit into engagement with said annular slot.
Claim 8
Dependent Claim
15 words
The bearing according to claim 1 wherein said wedges are provided with radially extending tabs.
Claim 9
Dependent Claim
22 words
The bearing according to claim 7 wherein said cylindrical member is provided with an axially extending shoulder extending over the radial tabs.
Claim 10
Dependent Claim
41 words
The bearing according to claim 7 including a bayonet ring adapted to be located over said tabs, said ring having an opening and an inclined surface whereby said tabs may be moved in the axial direction by rotation of said ring.
Claim 11
Dependent Claim
25 words
The bearing according to claim 9 wherein said inclined surface terminates in a flat surface extending transversely to the axial direction to secure said tab.
