Unit handled roller clutch subassembly

Claim 2

In a unit handled roller clutch subassembly having a sheet metal cage with a single end ring portion and a plurality of circumferentially spaced, integral tab portions extending in cantilevered fashion therefrom in an axial direction, a plurality of bearing blocks of low friction material having inner and outer bearing surfaces mounted on respective tab portions for centering inner and outer clutch races with respect to each other, each of said bearing blocks having a circumferential slot receiving an associated tab portion for securement to the cage and a circumferential extension spaced from the end ring portion for retaining a roller in the axial direction, the improvement comprising: each of said bearing blocks having a second slot for mounting a tickler spring to engage a roller and urge it toward an adjacent bearing block.

Claim 3

In a unit handled roller clutch subassembly having a sheet metal cage with a single end ring portion and a plurality of circumferentially spaced, integral tab portions extending in cantilevered fashion therefrom in an axial direction, a plurality of bearing blocks of low friction material having inner and outer bearing surfaces mounted on respective tab portions for centering inner and outer clutch races with respect to each other, each of said bearing blocks having a circumferential slot receiving an associated tab portion for securement to the cage and a circumferential extension spaced from the end ring portion for retaining a roller in the axial direction, the improvement comprising: each of said tab portions having a bearing block mounted thereon, and each of said bearing blocks having a radial slot open at one radial end for mounting a tickler spring to engage a roller and urge it toward an adjacent bearing block, said radial slot being adjacent an end of the bearing block having the circumferential extension.

Claim 4

In a unit handled roller clutch subassembly having a sheet metal cage with a single end ring portion and a plurality of circumferentially spaced, integral tab portions extending in cantilevered fashion therefrom in an axial direction, a plurality of bearing blocks of low friction material having inner and outer bearing surfaces mounted on respective tab portions for centering inner and outer clutch races with respect to each other, each of said bearing blocks having a circumferential slot receiving an associated tab portion for securement to the cage and a circumferential extension spaced from the end ring portion for retaining a roller in the axial direction, the improvement comprising: each of said tab portions having a bearing block mounted thereon, and each of said bearing blocks having a radial slot open at one radial end for mounting a tickler spring to engage a roller and urge it toward an adjacent bearing block, said radial slot being adjacent an end of the bearing block having the circumferential extension.

Claim 5

In a unit handled roller clutch subassembly having a sheet metal cage with a single end ring portion and a plurality of circumferentially spaced, integral tab portions extending in cantilevered fashion therefrom in an axial direction, a plurality of bearing blocks of low friction material having inner and outer bearing surfaces mounted on respective tab portions for centering inner and outer clutch races with respect to each other, each of said bearing blocks having a circumferential slot receiving an associated tab portion for securement to the cage and a circumferential extension spaced from the end ring portion for retaining a roller in the axial direction, the improvement comprising: each of said tab portions having a support arm and a retention finger having an outside edge portion disposed in narrow side portions of the associated circumferential slot, and each of said bearing blocks having a radial slot open at one radial end for mounting a tickler spring to engage a roller and urge it toward an adjacent bearing block, said radial slot being adjacent an end of the bearing block having the circumferential extension and said circumferential extension being spaced from the adjacent bearing block by less than a roller diameter.

Claim 6

In a unit handled roller clutch subassembly having a sheet metal cage with a single end ring portion and a plurality of circumferentially spaced, integral tab portions extending in cantilevered fashion therefrom in an axial direction, a plurality of bearing blocks of low friction material having inner and outer bearing surfaces mounted on respective tab portions for centering inner and outer clutch races with respect to each other, each of said bearing blocks having a circumferential slot receiving an associated tab portion for securement to the cage and a circumferential extension spaced from the end ring portion for retaining a roller in the axial direction, the improvement comprising: each of said tab portions having a support arm and a retention finger having an outside edge portion disposed in narrow side portions of the associated circumferential slot, and each of said bearing blocks having a radial slot open at one radial end for mounting a tickler spring to engage a roller and urge it toward an adjacent bearing block, said radial slot being adjacent an end of the bearing block having the circumferential extension and said circumferential extension being spaced from the adjacent bearing block by less than a roller diameter.
