Abstract
Abstract Mechanism for axially shifting an anti-friction bearing mounted in a bore of a housing extension or the like. The mechanism comprises an annular member such as the outer ring of the bearing mounted in the bore which has at least one radially outwardly directed protrusion engaging through an axial slit in the housing extension. The extension has external screw threads adjacent the axial slits to receive locking nuts on either side of the protrusion to fix the annular member in a selected position relative to the extension.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
113 words
Mechanism for axially shifting an anti-friction bearing mounted in a bore of a housing extension (1) or the like comprising an annular member (4) mounted in said bore, at least one radially outwardly directed protrusion (5) connected to said annular member projecting through an axially extending slit (6) in said extension (1), the outer peripheral surface of said extension being provided with threads (7) adjacent said slit and two adjusting locking nuts (8, 9) engageable on said thread (7) on opposite sides of said protrusion (5) thereby permitting axial adjustment of said annular member in either axial direction and locking said annular member in a predetermined position against axial displacement in either direction.
Claim 2
Dependent Claim
113 words
Mechanism for axially shifting an anti-friction bearing mounted in a bore of a housing extension (1) or the like comprising an annular member (4) mounted in said bore, at least one radially outwardly directed protrusion (5) connected to said annular member projecting through an axially extending slit (6) in said extension (1), the outer peripheral surface of said extension being provided with threads (7) adjacent said slit and two adjusting locking nuts (8, 9) engageable on said thread (7) on opposite sides of said protrusion (5) thereby permitting axial adjustment of said annular member in either axial direction and locking said annular member in a predetermined position against axial displacement in either direction.
Claim 3
Dependent Claim
43 words
A mechanism as claimed in claim 1 including a plurality of circumferentially spaced protrusions and a plurality of slits in said extension corresponding in number to said protrusions and circumferentially spaced at predetermined angular distance to receive the protrusions of said annular member.
Claim 4
Dependent Claim
28 words
A mechanism as claimed in claim 1 wherein said annular member comprises the outer ring of the bearing and said protrusions are formed integrally with said outer ring.
Claim 5
Dependent Claim
28 words
A mechanism as claimed in claim 1 wherein said protrusions are formed by pins or the like which are suitably connected to the annular member by fastening means.
Claim 6
Dependent Claim
23 words
A mechanism as claimed in claim 4 wherein the pins are connected to the outer ring of the bearing by soldering or welding.
Claim 7
Dependent Claim
38 words
A mechanism as claimed in claim 1 including a pinion gear assembly mounted in said extension and wherein said bearing comprises a combined tapered roller and angular contact ball bearing supported on the shaft of said pinion gear.
