ABSTRACT:
A loose joint assembly for linking two segments of a shaft which are substantially aligned at either end of the joint assembly co-axially about a axis of rotation. The joint assembly includes a male coupling member disposed co-axially within a female coupling member with an intermediate bearing member to align the coupling members. The male coupling member has a plurality of circumferentially spaced flats located within the space enclosed by the female coupling member. A corresponding plurality of openings, preferably in the form of slots extending in the circumferential direction, are located in the female coupling member, each slot being aligned with a corresponding flat. A drive pin is attached to the male coupling member at each flat and extends radially from the flat and at least partially into the corresponding slot in the female coupling member. The dimension of each opening in the direction of the longitudinal axis is selected to be only slightly larger than the dimension of the portion of the drive pin extending through the opening. The dimension of the slot in the circumferential direction is selected to be longer than the diameter of the drive pin extending into the opening. This configuration permits a limited amount of relative angular rotation between the male and female coupling members for limiting angular misalignment between the shaft segments while also permitting the shaft segments to lock in movement together at the extreme of relative angular movement between the shaft segments in either direction. Removing the pins, or disengaging them from the openings, permits the joint assembly to collapse axially.
