ABSTRACT:
A pair of relatively telescoped inner and outer sleeves are provided and the inner sleeve includes first and second end portions. The second end portion of the inner sleeve includes at least one generally radial slot formed therethrough and defines a step recess opening radially outwardly of the inner sleeve and longitudinally therealong outwardly of the first end of the inner sleeve. The outer sleeve defines a radially inwardly opening recess which also opens axially in a direction in which the second end of the inner sleeve faces and the step recesses are registered with each other and together define a circumferential cavity between relatively telescoped portions of the inner and outer sleeves. Axially extending and circumferentially spaced threaded fasteners are secured between the sleeves for forcing the sleeves in opposite axial directions relative to each other to reduce the axial extent of the cavity and the cavity includes force direction change structure disposed therein operative to convert a portion of the force generated by the fasteners into generally radial inward force on the inner sleeve second end at points spaced circumferentially thereabout to thereby radially inwardly force circumferentially spaced portions of the second end of the inner sleeve tightly against a shaft upon which the inner sleeve is disposed for high torque transfer between the inner sleeve and the shaft.
