ABSTRACT:
A resilient rotary coupling and a marine drive including same are described. The coupling includes inner and outer rotary members. The inner surface of the outer rotary member and the periphery of the inner member are of similar configuration and include, when viewed in cross section, at least two arcs of greater radius of curvature symmetrically disposed about the axis of rotation connected in alternate manner by an equal number of arcs of lesser radius of curvature, the arcs of greater radius of curvature being located closer to the axis of rotation than the arcs of lesser radius of curvature, the center of curvature of each of said arcs lying on or within the boundary of the closed figure defined by the inner surface in said section. The arcs are connected to one another without any abrupt change of radius or radius of curvature. Resilient means are disposed between the outer and inner rotary members. The resilient means is in radial compression and contacts completely in the circumferential direction of the members at least a portion of the inner surface of the outer member and the periphery of the inner member. The coupling may be designed so as to permit slippage upon application of loads in excess of design or to permit torsional shock absorption up to a maximum torque load at which time the inner and outer rotary members mechanically lock up relative to one another thereby preventing further angular displacement of them relative to one another.
