Abstract
A stop assembly for limiting relative rotation comprising inner and outer coaxial members relatively rotatable but longitudinally fixed with respect to each other. The outer member at least partially surrounds the inner member and is at least partially radially spaced therefrom so that an elongate annular space is formed between the members. A first stop surface is provided at one end of the annular space facing axially inwardly. A stop nut is disposed in the annular space coaxial therewith. The nut has a radial split therethrough. The nut is rotatable and longitudinally movable with respect to one of the members and longitudinally movable but not rotatable with respect to the other member. The nut further includes a second stop surface at one end opposed to the first stop surface. One of the stop surfaces inclueds a stop area engageable with the other stop surface adjacent the trailing side of the split, as the nut is advanced toward the first stop surface, with the remainder of the one stop surface spaced from the other stop surface.
