<p>A shaft-carried speed reducer (10) is provided having an adaptable mounting arrangement. The hub (30) of the speed reducer (10) is configured having a substantially cylindrical axial bore (44). At least one annular groove (46) may be defined in the axial bore (44) to receive a snap ring (48) when desired. A removable adapter (50) having a tapered interior surface (54) may then be situated in the hub bore (44) to abut the snap ring (48). As an alternative to such a snap ring, an annular flange (64) may be provided on the removable adapter to engage an end face of the hub. A tapered sleeve member (52) engages the tapered interior surface (54) 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 the hub in some configuration. Further, some configurations permit a pair of adapters and corresponding sleeve members bo be used. The adapter and snap ring, if any, may be romoved when the hub is to be secured to a screw conveyor drive shaft or the like.</p> |
