ABSTRACT:
A cyclic phase-change coupling in which opposed ends of two members rotatable on parallel offset axes are connected by an intermediate member through guide means which restrict lateral motion of the intermediate member with respect to both other members to separate arcuate paths, the axial projections of which intersect within the lateral boundaries of the intermediate member. In a preferred form, the arrangement comprises a curved key and groove variation of a standard Oldham shaft coupling that provides a cyclic phase change between the offset shafts rather than the fixed phase rotation of the Oldham construction.
