| description | 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. |
