Abstract
Abstract A retaining assembly providing a simplified means and procedure for mounting tapered roller bearings on a shaft in a manner as also insures accurate bearing setting. Said assembly includes a plain metal washer which is located by and held tight and square against the conventional shoulder provided on the shaft which is to receive such a bearing just outwardly of its journal portion by the axial biasing action which a beveled retaining ring sprung into a circumferential groove provided therefor in the shaft just outwardly of said outer shoulder exerts thereon in tending to contract to its unstressed diameter (cf. U.S. Pat. No. 2,509,081, dated May 23, 1950).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
Means mounting and accurately ''''setting'''' tapered roller bearings for wheels and the like on a shaft provided with a journal portion terminating in a conventionally-located outer shoulder and a reduced-diameter outer-end portion which extends axially beyond said shoulder, comprising: washer means assembled on said reduced-diameter outer-end portion of the shaft and having effective outer diameter greater than that of the immediately adjacent journal portion thereof, and readily removable and replaceable retaining-ring means assembled on said reduced-diameter end of the shaft axially-outwardly of said washer means and exerting continuous axial force in inward direction on said washer means of a magnitude maintaining said washer means in tight abutting engagement against said shoulder, the construction and arrangement being such that said outer-end portion of the shaft is unconventionally non-threaded and of relatively short length and further that proper running clearance is assured.
Claim 2
Dependent Claim
140 words
Means mounting and accurately ''''setting'''' tapered roller bearings for wheels and the like on a shaft provided with a journal portion terminating in a conventionally-located outer shoulder and a reduced-diameter outer-end portion which extends axially beyond said shoulder, comprising: washer means assembled on said reduced-diameter outer-end portion of the shaft and having effective outer diameter greater than that of the immediately adjacent journal portion thereof, and readily removable and replaceable retaining-ring means assembled on said reduced-diameter end of the shaft axially-outwardly of said washer means and exerting continuous axial force in inward direction on said washer means of a magnitude maintaining said washer means in tight abutting engagement against said shoulder, the construction and arrangement being such that said outer-end portion of the shaft is unconventionally non-threaded and of relatively short length and further that proper running clearance is assured.
Claim 3
Dependent Claim
60 words
Means according to claim 1, wherein said washer means comprises a stamping of annular shape fashioned from commercial sheet metal whose central opening has diameter slightly greater than that of the shaft outer-end portion whereby it may be assembled and positioned thereon by being slipped over said outer-end portion and shifted axially therealong to an initial shoulder-abutting position as aforesaid.
Claim 4
Dependent Claim
79 words
Means according to claim 1, wherein said retaining-ring means comprises a beveled spring-retaining ring assembled and being in stressed condition in a circumferential groove provided therefor in the peripheral surface of said outer-end shaft portion outwardly of said shaft shoulder, said retaining ring in tending to return to its unstressed condition exerting inward axial force on the outer face of said washer means of magnitude as holds said washer means in forceful abutting engagement against said shoulder as aforesaid.
Claim 5
Dependent Claim
78 words
Means according to claim 2, and wherein said retaining-ring means comprises a ''''beveled'''' spring-retaining ring assembled and being in stressed condition in a circumferential groove provided therefor in the peripheral surface of said outer-end shaft portion outwardly of said shaft shoulder, said retaining ring in tending to return to its unstressed condition exerting inward axial force on the outer face of said washer of magnitude as holds said washer in forceful abutting engagement against said shoulder as aforesaid.
Claim 6
Dependent Claim
63 words
Means according to claim 4, and wherein said circumferential groove is defined in part by side walls and one of said side walls has inclination complemental to that of the bevel of said retaining ring, said one side wall cooperating with said bevel in rendering said retaining ring operative to exert inward axial force on the outer face of the washer as aforesaid.
Claim 7
Dependent Claim
42 words
Means according to claim 1, wherein said washer means and reduced-diameter outer end of the shaft are provided with cooperating means preventing relative rotation of the washer means with respect to said shaft outer-end portion on which said washer means is mounted.
Claim 8
Dependent Claim
33 words
Means according to claim 6, and wherein said last means comprises a ''''flat'''' on the surface of the shaft outer end and a mating ''''flat'''' on the inner edge of said washer means.
