摘要

The fastening device (10) for fixing a wheel (14) to a central hub opening (15) on a shaft (12) comprises an outer ring (20) set in the opening (15) and an inner ring (30) set in the outer ring. The outer ring has cylindrical outer face (21), tapering inner face (22), support jaws (24) fitted over the shaft (12), a cylindrical inner face (25) at the larger end of the tapering inner face, and an end jaw (26) with enlarged diameter at one end of the outer ring. The inner ring has a cylindrical face (31) set over the shaft (12), a comlementary outer face (32) matching the tapering inner face of the outer ring, and a flanged area (36) of enlarged diameter at one end of the inner ring (30). Axial bores (37) extend through the flanged area and fasten (40) extends through the bores and stand in screwed engagement with the internally threaded bores (17) which are formed in the wheel. ADVANTAGE - Easier fixing allowing correct alignment of the wheel.
