Abstract
Abstract A tapered roller bearing having a non-shouldered outer race, an inner race with a shoulder at its large diameter end, a cage having roller pockets to receive rollers and a ring having radially projecting tangs thereon extending from an annular skirt with the tangs positioned to snap into locking engagement with suitable notches located at the large end of the roller pockets in the cage.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
213 words
A tapered roller bearing comprising in combination an inner race having a first tapered pathway and a thrust shoulder at its larger diameter end, said thrust shoulder having a frusto-conical outer diameter surface tapered oppositely to said first tapered pathway, an outer race having a second tapered pathway, a plurality of tapered rollers disposed between and in frictional engagement with said first tapered pathway and said second tapered pathway, a cage for circumferentially spacing said rollers and for limiting movement of said rollers axially with respect to said inner race, said cage comprising a separator cage open at one end and having a shouldered small diameter end ring and a large diameter end ring forming said open end with crossbars extending therebetween to form windows adapted to individually receive said rollers, said large diameter end ring having circumferentially spaced notches therein adjacent to said windows, and a retaining ring positioned within said large diameter end ring to partly close the open end of said separator cage, said retaining ring including flexible tangs extending axially therefrom for engagement into said notches, said retaining ring having an inner diameter surface which cooperates with said frusto-conical outer diameter surface to limit the axial movement of said cage and said rollers with respect to said inner race.
Claim 2
Dependent Claim
213 words
A tapered roller bearing comprising in combination an inner race having a first tapered pathway and a thrust shoulder at its larger diameter end, said thrust shoulder having a frusto-conical outer diameter surface tapered oppositely to said first tapered pathway, an outer race having a second tapered pathway, a plurality of tapered rollers disposed between and in frictional engagement with said first tapered pathway and said second tapered pathway, a cage for circumferentially spacing said rollers and for limiting movement of said rollers axially with respect to said inner race, said cage comprising a separator cage open at one end and having a shouldered small diameter end ring and a large diameter end ring forming said open end with crossbars extending therebetween to form windows adapted to individually receive said rollers, said large diameter end ring having circumferentially spaced notches therein adjacent to said windows, and a retaining ring positioned within said large diameter end ring to partly close the open end of said separator cage, said retaining ring including flexible tangs extending axially therefrom for engagement into said notches, said retaining ring having an inner diameter surface which cooperates with said frusto-conical outer diameter surface to limit the axial movement of said cage and said rollers with respect to said inner race.
Claim 3
Dependent Claim
54 words
A tapered roller bearing according to claim 1 wherein said retaining ring includes an annular ring of plastic material having an outer diameter less than the inside diameter of said large diameter end ring, said flexible tangs, integral with said annular ring, each having an angled edge at its radially outward extending free edge.
Claim 4
Dependent Claim
60 words
A tapered roller bearing according to claim 1 wherein said retaining ring includes a stamped metal annular ring in the form of an annular segment of a truncated cone and wherein said tangs, integral with said annular cone, are substantially S-spring shaped to permit their flexing during insertion of the retaining ring into the open end of said separator cage.
Claim 5
Dependent Claim
201 words
A non-separable, unit-handled bearing subassembly comprising in combination an inner race having a tapered pathway and a thrust shoulder at its larger diameter end, said thrust shoulder having a frusto-conical outer diameter surface tapered oppositely to said tapered pathway, a plurality of tapered rollers, a cage for circumferentially spacing said rollers and for limiting movement of said rollers axially and radially with respect to said inner race, said cage comprising a separator cage open at one end and having a shouldered small diameter end ring and a large diameter end ring forming said open end with radially inward tapered crossbars extending therebetween to form tapered windows adapted to individually receive said rollers and retain them in engagement with said tapered pathway, said large diameter end ring having circumferentially spaced notches therein adjacent to said windows, and a retaining ring positioned within said large diameter end ring to partly close the open end of said separator cage, said retaining ring including flexible tangs extending into engagement with said notches, said retaining ring having an inner diameter surface which cooperates with said frusto-conical outer diameter surface to limit the axial movement of said cage and said rollers with respect to said inner race.
Claim 6
Dependent Claim
201 words
A non-separable, unit-handled bearing subassembly comprising in combination an inner race having a tapered pathway and a thrust shoulder at its larger diameter end, said thrust shoulder having a frusto-conical outer diameter surface tapered oppositely to said tapered pathway, a plurality of tapered rollers, a cage for circumferentially spacing said rollers and for limiting movement of said rollers axially and radially with respect to said inner race, said cage comprising a separator cage open at one end and having a shouldered small diameter end ring and a large diameter end ring forming said open end with radially inward tapered crossbars extending therebetween to form tapered windows adapted to individually receive said rollers and retain them in engagement with said tapered pathway, said large diameter end ring having circumferentially spaced notches therein adjacent to said windows, and a retaining ring positioned within said large diameter end ring to partly close the open end of said separator cage, said retaining ring including flexible tangs extending into engagement with said notches, said retaining ring having an inner diameter surface which cooperates with said frusto-conical outer diameter surface to limit the axial movement of said cage and said rollers with respect to said inner race.
