<p>A shaft-carried speed reducer is provided having an adaptable mounting arrangement. The hub of the speed reducer is configured having a substantially cylindrical axial bore. At least one annular groove may be defined in the axial bore to receive a snap ring when desired. A removable adapter having a tapered interior surface may then be situated in the hub bore to abut the snap ring. As an alternative to such a snap ring, an annular flange may be provided on the removable adapter to engage an end face of the hub. A tapered sleeve member engages the tapered interior surface defined on the removable adapter to effect securement of the hub to the shaft. If a single adapter is used, it may be inserted from either side of the hub in some configurations. Further, some configurations permit a pair of adapters and corresponding sleeve members to be used. The adapter and snap ring, if any, may be removed when the hub is to be secured to a screw conveyor drive shaft or the like.</p> |
