ABSTRACT:
A shaft assembly having a first shaft and a second shaft interconnected by a bipot joint is disclosed. The first shaft and the second shaft are disposed in overlapping spaced relationship. The bipot joint includes a pivot block sandwiched between the first shaft and the second shaft. The pivot defines a mounting surface abutting one of the first and second shafts, and a semi-annular surface opposing the mounting surface and abutting the other of the first shaft and the second shaft. A fastener extends through a bore defined by the first shaft, the pivot block and the second shaft to interconnect the first shaft, the pivot block and the second shaft. The fastener includes a spring to bias the first shaft, the pivot block and the second shaft together, thereby de-lashing the bipot joint.
