ABSTRACT:
Any suitable strip material, including cold-rolled steel, is stamped to establish first and second laterally extending portions interconnected by a connecting segment, with a locating hole located midway between the free or distal ends of the laterally extending portions. The connecting segment is sized so that no dimension of the connecting segment as measured from the center of the locating hole exceeds a preselected dimension corresponding with the diameter of a shaft with which the adapter is to be used. The central connecting segment may or may not be symmetrically positioned relative to a center reference line extending longitudinally along the laterally extending segments. One or more laterally extending marginal edges of the laterally extending sections may be tapered in order to permit overbending or overforming of the sheet material. The locating hole positions the strip, and the flat material is folded and formed to establish curvature of the laterally extending segments that then extend from the central segment in cantilever fashion. The curvature established corresponds to the curvature of a shaft with which the adapter is to be used. After the tube sector adapter has been formed, it can be readily assembled to a shaft without crimping and may be easily slid manually onto the shaft. The connecting segment positively locates the cantilever segments when the connecting segment bottoms against the shaft. The adapters slip onto the shaft until the connecting segment closely approaches the end of the shaft whereupon finger pressure will seat the adapter on the shaft. Once seated, the tube sector adapter is interlocked with and retained on the shaft, but may also be removed with finger pressure.
