Abstract
Abstract A bearing is mounted to a casing by undercutting the casing adjacent a shaft aperture to form a recessed shoulder, inserting a bearing mounting sleeve having an outer flange at one end and inner bearing retaining means at the other end into the aperture so that the flange is against the shoulder, and inserting the bearing into the sleeve against the bearing retaining means. The invention is particularly useful in repairing damaged transmissions of the type including output transfer gears.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
311 words
In a vehicular transmission of the type having straight drive transmission means for powering a primary drive train; an associaTed casing; transfer means for powering a secondary drive train and including a driven shaft extending into an aperture in the transmission casing, and an output transfer gear mounted on the shaft, said casing including an aperture adapted for receiving said shaft; and anti-friction transfer bearing means adapted to rotatably journal said shaft in said aperture; said bearing means being subject to displacement in a prescribed axial direction, an improved apparatus for rotatably mounting the gear carrying driven shaft to the transmission casing so as to couple the shaft to the casing rotatably while also arresting translation thereof in said axial direction, said gear being subject to damaging impact against adjacent surfaces as a consequence of such translation; said apparatus comprising: a. means defining a recess in the surface of the casing around the shaft aperture which terminates at a shoulder extending outwardly from the bore of the aperture; b. a bearing receiving sleeve securely positioned within said recess, said sleeve including a barrel section disposed within said aperture bore, a flange extending radially outward from the exterior end of said sleeve so as to be disposed within said recess against said recessed shoulder to provide a sleeve flange-recessed shoulder interface, and bearing retaining means extending radially inward from the inner end of said barrel section; and c. said bearing means being secured within said sleeve barrel adjacent said sleeve bearing retaining means to provide a bearing retaining means-bearing interface, the gear carrying shaft passing through the bearing for rotation therein with the transfer gear located exteriorly of said bearing, whereby axial loads on the driven shaft applied in said axial direction are coupled to the casing and thereby resisted through the sleeve flange-recessed shoulder interface and the bearing retaining means-bearing interface.

In a vehicular transmission of the type having straight drive transmission means for powering a primary drive train; an associaTed casing; transfer means for powering a secondary drive train and including a driven shaft extending into an aperture in the transmission casing, and an output transfer gear mounted on the shaft, said casing including an aperture adapted for receiving said shaft; and anti-friction transfer bearing means adapted to rotatably journal said shaft in said aperture; said bearing means being subject to displacement in a prescribed axial direction, an improved apparatus for rotatably mounting the gear carrying driven shaft to the transmission casing so as to couple the shaft to the casing rotatably while also arresting translation thereof in said axial direction, said gear being subject to damaging impact against adjacent surfaces as a consequence of such translation; said apparatus comprising: a. means defining a recess in the surface of the casing around the shaft aperture which terminates at a shoulder extending outwardly from the bore of the aperture; b. a bearing receiving sleeve securely positioned within said recess, said sleeve including a barrel section disposed within said aperture bore, a flange extending radially outward from the exterior end of said sleeve so as to be disposed within said recess against said recessed shoulder to provide a sleeve flange-recessed shoulder interface, and bearing retaining means extending radially inward from the inner end of said barrel section; and c. said bearing means being secured within said sleeve barrel adjacent said sleeve bearing retaining means to provide a bearing retaining means-bearing interface, the gear carrying shaft passing through the bearing for rotation therein with the transfer gear located exteriorly of said bearing, whereby axial loads on the driven shaft applied in said axial direction are coupled to the casing and thereby resisted through the sleeve flange-recessed shoulder interface and the bearing retaining means-bearing interface.
Claim 3
Dependent Claim
50 words
The apparatus of claim 1 wherein said bearing receiving sleeve is press fit into said recess, and said bearing is press fit into said bearing receiving sleeve; and wherein said shaft is coupled to said casing by supplemental axial retainer means coacting with the bearing means to prevent such translation.
Claim 4
Dependent Claim
247 words
In a power transmitting arrangement comprising a fixed housing means including a bore portion; drive shaft means journalled in said housing means to be disposed along a predescribed longitudinal axis for rotation thereabout; driven means affixed at a predescribed position on said shaft means to be rotated therewith; antifriction bearing means coupling said shaft means rotatably to said housing means in said bore portion; a retainer means cooperative between said shaft and said housing for maintaining axial placement of said shaft and said driven means relative to said housing when said bearing means is subject to being thrust in a first direction along said axis, whereby said shaft and driven means may also be so thrust, displaced, and thereby damaged or interferred with upon failure of said retaining means; the combination therewith of; annular stop means adapted to couple said bearing means to said housing means at said bore portion and to prevent displacement of said bearing means and thus said shaft means in said axial direction upon failure of said retaining means, said stop means comprising a body portion disposed in said bore and extending along said axis and surrounding said bearing means, a first flange portion disposed at one end of said body portion extending radially inwardly therefrom to engage at least a portion of said bearing means, and a second flange portion disposed at the other end of said body portion and adapted to engage said housing means at the periphery of said bore.
