US Classification:

403373, 4033742, 4033743, 4033744, 294261, 29428, 2952501, 2952511

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.

International Classification:

B21D 39/03
B23P 11/00

US Classification:

29434, 29428, 2952501

Abstract:

A method for coupling first and second mechanical members is provided. In one embodiment, the method includes providing at least one insulating sleeve and a mating locking member. The locking member may be configured to cooperate with the at least one insulating sleeve to secure the first and second mechanical members to one another. Additionally, the at least one insulating sleeve may facilitate electrical isolation of the first and second members. Various additional component mounting systems, methods, and locking members are also provided.

International Classification:

F16C 43/00

US Classification:

384538

Abstract:

A system for mounting mechanical components is provided. In one embodiment, the system includes a sleeve having a surface for interfacing with a hollow outer member, a surface for interfacing with an inner member having an inner circumferential lip, and a threaded extension. The system also includes a locking member having exterior threads configured to engage the threaded extension of the sleeve, and a varying depth groove configured to mate with the inner circumferential lip of the sleeve. A locking member and methods for sleeve mounting systems are also provided.

Appl. No.:

8/587028

Inventors:

Howard M. Martinie - Simpsonville SC
Roman M. Wajda - Greer SC

Assignee:

Allen-Bradley Company, Inc. - Milwaukee WI

International Classification:

F16L 2704

US Classification:

384538

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.
