20090003930 | PINCH BOLT - SPLIT HUB ATTACHMENT ASSEMBLY - The present invention provides an assembly for attaching a hub to a shaft. The hub, which may be a portion of a gear, pulley, chain sprocket or other power carrying device, includes a collar or annular wall having two axially extending relief cuts on opposite sides of a shaft opening, which define a pair of opposed projections or clamp members. The clamp members include opposed flats on the inside of the shaft opening which engage complementarily configured flats on the shaft. A threaded fastener such as a bolt extends through smooth radial bores in one clamp member and the shaft and into a complementarily threaded bore in the other clamp member. The internal flats of the hub include opposed arcuate, axially extending reliefs. The outside surface of the hub proximate the smooth bore defines a chordal surface which the bolt engages. | 01-01-2009 |

20100143030 | SHAFT ANTISEIZING TYPE SPROCKET - A shaft antiseizing type sprocket in which seizing liable to occur in the contact portion between the sprocket and the sprocket shaft is completely avoided for a long period of use. Effecting replacement is possible without use of a special-purpose removing tool or a fixing tool with a rotating body. The shaft antiseizing type sprocket has a boss portion which is integrally molded with a sprocket tooth portion. The boss has a shaft bore, the inner circumferential surface of which is adapted to be fixed to a sprocket shaft. A solid lubricant is embedded in the boss portion, and is disposed in a partially exposed state toward the shaft bore inner circumferential surface of the boss portion. | 06-10-2010 |
20110052316 | Spline Shaft Assembly - A spline shaft assembly includes a rotatable shaft extending along an axial direction and having an outer surface, and a plurality of first grooves formed in the outer surface. A transmission module is formed with a through hole and has an inner surface defining the through hole, and a plurality of axially extending second grooves formed in the inner surface. Each of the first and second grooves is defined by a semi-circular groove-defining wall. The rotatable shaft extends through the through hole. A spline key set has a plurality of cylindrical keys extending along the axial direction and disposed between and engaging the first grooves and the second grooves, and at least two positioning members connected to the transmission module and associated with the cylindrical keys such that the transmission module and the cylindrical keys are co-rotatable. | 03-03-2011 |
20110268498 | Universal Shaft Key and Repair Preform - A preform having a shape including a surface for bearing against a flatted shaft and a surface approximating the shape of a cylindrical portion of an exterior lateral surface of the shaft and having a protrusion thereon which is generally complementary to a keyway in a fixture to be attached to the shaft forms a universal substitute for conventional key and keyway joints between a shaft and a fixture. The joint formed using the preform is stronger, more robust and more resistant to damage and/or wear during use than a key and keyway joint while formation as a preform allows application to a wider variety of applications while facilitating repairs and allowing repairs to be performed in the field with easily portable hand or power tools. | 11-03-2011 |
20120099926 | HUB-SHAFT ASSEMBLY - Disclosed herein is a hub and shaft assembly. The assembly includes a shaft having an outer surface, a hub having an inner surface configured to engage the outer surface of the shaft, and a first fastening device positioned within a first opening formed in the engaged outer surface of the shaft and the inner surface of the hub along lengths of the shaft and the hub. A method of securing a hub to a shaft is further disclosed. | 04-26-2012 |
