Anti-rotation lock asembly includes a male threaded member that may be releasably locked in any desired axially adjusted position relative to a mating female threaded member by means of one or more wedge keys that are forced axially into notches in an end face of the female threaded member and radially against flats or keyways on the male threaded member. Surrounding the male member is a key retaining ring which retains the wedge keys on the male member when the wedge keys are disengaged from the female member to permit relative rotation between the male and female members for adjustment of the male member in or out relative to the female member. The wedge keys are retained in radial slots in the retaining ring which prevent relative axial movement between the wedge keys and retaining ring while permitting limited radial movement therebetween.
An anti-rotation lock assembly between an internally threaded female member and an externally threaded male member in threaded engagement with each other comprising lock means movable between a first position permitting relative rotation between said members for adjustment of said male member axially in or out relative to said female member and a second position locking said members against relative rotation, force applying means for releasably moving said lock means from said first position to said second position, and retaining means for retaining said lock means on said male member when said force applying means is released, said retaining means comprising a retaining ring surrounding said male member, said retaining ring having a central opening of a size somewhat larger than the outer diameter of a threaded end of said male member, and a radial slot extending radially outwardly from said central opening, said lock means having a portion thereof mounted in said radial slot for radial movement of said lock means toward and away from the exterior surface of said threaded end.
An anti-rotation lock assembly between an internally threaded female member and an externally threaded male member comprising a notch in an end face of said female member, an external flat on said male member, a locking member having an axial projection adapted to fit in said notch and an internal flat adapted to mate with said external flat on said male member, force applying means for releasably forcing said locking member both axially and radially in turn to force said projection on said locking member into said notch and said internal flat on said locking member against said external flat on said male member, and retaining means for retaining said locking member on said male member when said force applying means is released, said retaining means comprising a retaining ring surrounding said male member, said retaining ring having a central opening of a size somewhat larger than the outer diameter of a threaded end of said male member, and a radial slot extending radially outwardly from said central opening, said locking member having a portion thereof mounted in said radial slot for limited radial movement of said locking member toward and away from said threaded end of said male member.
An anti-rotation lock assembly between an internally threaded female member and an externally threaded male member comprising a pair of notches in an end face of said female member, a pair of external flats on said male member, a pair of locking members each having an axial projection adapted to fit in said notches in said end face of said female member and an internal flat adapted to mate with said external flats on said male member, force applying means for releasably forcing said locking members both axially and radially in turn to force said projections on said locking members into said notches and said internal flats on said locking members against said external flats on said male member, and retaining means for retaining said locking members on said male member when said force applying means is released, said retaining means comprising a retaining ring surrounding said male member, said retaining ring having a central opening of a size somewhat larger than the outer diameter of a threaded end of said male member, and a pair of circumferentially spaced radial slots extending radially outwardly from said central opening in said retaining ring, each of said locking members having a portion thereof mounted in said radial slots for radial movement of said locking members toward and away from said threaded end of said male member.
