ABSTRACT:
A device for connecting a wheel or wheel-like body to a shaft has tapered inner and outer wedge rings that can be formed over one another using a captive nut. An expanded inner ring has axial slits and fits over the shaft. The inner ring has a tapered outer peripheral surface portion and a threaded cylindrical portion extending along the shaft. An expandable outer ring has a plurality of part-cylindrical segments and can be inserted between the inner ring and the wall of an axial bore in the wheel or wheel-like body. The outer ring has a tapered inner surface which is complementary to the tapered outer surface of the inner ring. The outer ring has a first annular groove formed in its inner peripheral surface adjacent to its minimum inside diameter end and a second annular groove formed in its outer peripheral surface. The segments are held together by a retaining ring fitted in the second annular groove of the outer ring. A nut adapted for threaded engagement about the threaded surface of the inner ring is captive on the outer ring due to an annular projection which is engageable in the first annular groove of the outer ring, whereby the nut will lock or positively disengage the device even using a low taper angle.
