Abstract: A bearing assembly movably supports a component on a shaft. The bearing assembly includes a pair of annular bands spaced apart axially and projecting radially inwardly from the component. The bands form an annular slot therebetween. An annular bearing member is mounted on the shaft. The bearing member has a larger diameter central flange and a pair of smaller diameter rings projecting axially for opposite sided of the central flange. The central flange is received by the slot, and each ring is positioned between the shaft and a respective one of the bands. The bearing member has a T-shaped cross-sectional shape.

Abstract: The invention relates to a variable belt drive. There is a need for an improved variable belt drive. A variable belt drive includes a non-rotating piston housing which forms three piston bores. A rotatable input shaft is coupled to a power source and is supported by bearings in the piston housing. A first sheave is mounted for rotation with the shaft and is fixed axially to the shaft. A second sheave is mounted for rotation with the shaft and is slidable axially on the shaft. A piston is movable in each piston bore in response to fluid pressure. A non-rotating carrier engages an end of each the pistons. A thrust bearing has an outer race fixed to the carrier and an inner race fixed to the second sheave and rotatable with the second sheave. The carrier includes an annular surface which engages an outer surface of the outer race. An O-ring is received in a groove in the annular surface and engages the outer race to resist rotation of the outer race.
