Abstract
A bearing arrangement for the drive pinion of a marine transmission or the like reduces deflections of the shaft on which the pinion is mounted. The bearing arrangement mounts the pinion in part on the shaft and in part directly on the transmission housing, thus reducing loads imposed on the shaft by the pinion. The bushing which typically supports the pinion on the drive shaft is eliminated in favor of a first bearing supporting the input end of the pinion in the housing and a second bearing supporting the output end of the pinion on the shaft. Third and fourth bearings support the output and input ends of the shaft in the housing and on the pinion, respectively. Preferably, the first, second, and third bearings comprise single taper roller bearings which permit the points at which the effective loads are imposed on the shaft to be shifted and the running clearances of which are adjusted by a single shim pack. Deflections can be reduced still further by positioning the clutch return spring proximate an outer surface of the clutch.
