<p>Speed reducer, such as a screw conveyor drive, adapted to receive a shaft (30) within a tapered sleeve (130). The shaft (30) includes a tapered portion (31) adapted for engagement with the corresponding tapered portion (135) of the sleeve (130) on one side of a housing (15) when the shaft is inserted into the housing bore. On the other side of the housing (15), a split bushing (150) is provided for receipt within the sleeve (130), the split bushing (150), including a tapered surface (160) for mating engagement with the tapered surface (135) on the sleeve (130). A retainer plate (200) is provided that is adapted to be placed on the end of the shaft (30) extending through the bore. The retainer plate (200) has a center hole (215) for receipt of a capscrew (195) through the retainer plate (200) has a center hole (215) for receipt of a capscrew (195) through the retainer plate (200) and into the shaft (30) to securely maintain the shaft (30) in place. The retainer plate (200) further has a plurality of holes (205) dimensioned so that the head and shank of screws (170) may extend therethrough and a plurality of holes (210) dimensioned so that only the shank of screws (170) can extend therethrough. To demount the shaft (30), the retainer plate (200) and bushing (150) are removed, the retainer plate (200) replaced, and the screws (170) inserted through the smaller plurality of plate holes (210) and rotated, which causes the plate (200) to force the shaft (30) out of the bore.</p> |
