Abstract: A system is provided for securing two ends of a rotating member, such as a shaft, with respect to a non-rotating member, such as a mounting hub. Inner and outer sleeves have tapered surfaces and are positioned about the rotating member and provided within a bore of the non-rotating member. The tapered surfaces of the inner and outer sleeves cooperate in securing the shaft within the bore. The one or more inner sleeves collectively provide two threaded extensions for engagement with two nuts. Further, the one or more outer sleeves aggregately include two extensions, each having an annular groove to accommodate a lip formed in the nut. The system is engaged and disengaged through the interaction of the various tapered surfaces and the nuts, caused by the directional rotation of the nuts.

Abstract: A system is provided for securing a rotating member with respect to a non-rotating member. A hollow member, such as a mounting hub or an inner ring of a bearing assembly, includes an extension having an annular outer groove. One or more tapered sleeves serve to lock the hollow member about a mechanical component, such as a shaft. A nut engageable on a sleeve includes an eccentric front aperture adjacent to a concentric groove, thereby forming a lip of varying depth The system is engaged by rotation of the nut on the sleeve in one direction, and disassembled by counterrotation of the nut such that a portion of the varying depth lip co-acts with a lip formed by a groove on an outer sleeve or on the hollow member.

Abstract: A bearing assembly includes an improved clamping arrangement for securement to a shaft. The inner ring of the bearing assembly includes a tapered inner surface generally complementary to a tapered outer surface of a tapered adapter. Each of the tapered adapter and the inner ring member include an axial extension portion which are situated to be proximate one another during use. A nut is provided interconnecting the extension portions such that relative axial movement may be effected between the inner ring member and the tapered adapter. As a result, the bearing assembly may be secured to or removed from the shaft.
