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.

Dependent claims

A stop assembly for limiting relative rotation comprising:

an inner member;
an outer member coaxial with and at least partially surrounding said inner member, said outer member being at least partially radially spaced from said inner member to form an elongate annular space between said members;
means defining a first stop surface facing axially inwardly at one end of said annular space;
means permitting relative rotation but preventing relative longitudinal movement between said members;
and a stop sleeve disposed in said annular space coaxial therewith and having a radial split therethrough, said sleeve being rotatable and longitudinally movable with respect to one of said members and longitudinally movable but not rotatable with respect to the other of said members and having a second stop surface at one end generally opposed to said first stop surface, one of said stop surfaces including a stop area engageable with the other of said stop surfaces adjacent the trailing side of said split as said sleeve is advanced toward said first stop surface, with the remainder of said one stop surface being spaced from said other stop surface.
