US 5,211,488 A · Single tapered bushing for shaft mount

Abstract

A shaft-mounted bushing for connecting a rotating member to a shaft. The bushing includes a frame receiving a hub rotatably mounted therein. The hub includes an opening at one end thereof for receiving a shaft from the one end thereof. The hub includes a tapered portion which converges inwardly from the one end of the hub and toward the other end thereof. A sleeve is mounted into the hub from the one end of the hub and between the tapered portion of the hub and the cylindrical shaft. The outer portion of the sleeve converges inwardly from the one end of the hub and engages the hub. The sleeve presents an inward portion which is coaxial with and parallel to the cylindrical shaft for engaging the shaft in force transmitting relation ship therewith. The bushing assembly is completed by drawing the sleeve into the hub by way of a fastener located at the other end of the hub.

A shaft-mount bushing for connecting a rotating member to a driven shaft having an axis, said bushing comprising, in combination:

a frame defining an output side and an input side thereof;
a hub rotatably mounted on said frame, said hub having an opening at one end thereof for receiving said driven shaft generally coaxially therein adjacent said output side of said frame, said hub having a radially inwardly facing surface which tapers inwardly toward and to the other end of said hub adjacent an input side of said frame;
a sleeve mounted in said hub between said inwardly facing surface and said shaft, said sleeve having a large tapered end thereof adjacent said one end of said hub, a small tapered end adjacent said other end of said hub;
and
a radially outwardly facing surface which tapers inwardly from said one end of said hub to said other end of said hub adjacent said input side of said frame;
fastener means on said small tapered end of said sleeve for mating engagement with complementary fastener means;
complementary fastener means matingly engageable with said fastener means on said small tapered end of said sleeve for drawing said sleeve into and securing said sleeve in said hub from said input side of said frame;
and,
means for connecting an intermediate portion of said hub to an input shaft rotatably mounted to said frame,
