COUPLING ASSEMBLY AND APPLICATION TO DRIVEN COUPLING, ROBOTIC ARM AND DUAL DRIVE
A coupling comprises at least an inner annular member, an intermediate annular member and an outer annular member. The intermediate and outer annular members are positioned with respect to one another and with respect to the inner member by driven gear wheels acting on gear teeth associated with the inner and intermediate members. By coupling the outer member of one coupling of a series of couplings to the inner member of the next coupling of the series, a robot arm may be constructed in which drive can be transmitted from one end of the series to the other. By changing the potions of the members of the couplings in the series, the orientation of the robot arm may be change.

A coupling comprises an inner member (1) having an outer convex spherical periphery (S1) centred about a central point (C). The first inner member has a torsional axis (A1) extending through the central point. A second member outer ring (2) has an inner concave spherical periphery centred on the central point and complementary to the outer periphery of the inner member. One of the first inner member (1) and second member (2) has an elongate projection (M1) projecting parallel to a line extending radially of the central point into a corresponding elongate slot (K1) in the other. The slot and projection are elongate in a plane parallel the torsional axis (A1). The projection and slot act to transmit torque about the torsional axis (A1) from one to the other. The inner member and second member are rotatable one relative to the other about the said central point in a direction constrained by the projection and slot.

A coupling comprises a pair of members: a first member having an outer convex spherical periphery centred about a central point and a torsional axis extending through the central point, and a second annular member has an inner concave spherical periphery centred on the central point and complementary to the outer periphery of the inner first member. The spherical surfaces of the inner and outer members co-act to transmit radial loads there between and to transmit loads acting along the torsional axis there between. An axle arrangement extends radially of the central point and couples the first and second annular for transmitting torsional load from one to the other. The each of the pair of members is rotatable one relative to the other about the said central point in a direction constrained by the axle arrangement.
