Embodiment Construction

[0032] Figure 1 to Figure 4 Two example couplings 1 and 2 of the invention are shown joined by a shaft 3 used as a replacement for a Carden shaft.

[0033] Each of the couplings 1 and 2 includes an inner ring member 111 , a middle ring member 121 and an outer ring member 131 . The center of the inner member 111 is located on the central axis X. As shown in FIG. The inner member 111 has an outer convex spherical surface 112 , which is a convex spherical surface centered at point C on the central axis X .

[0034] The inner annular member 111 has a central aperture 100 to receive the shaft 3 . The central aperture 100 has a keyway 101 which is engaged by a corresponding key 102 on the shaft 3 . Alternatively, the ends of the shaft member 3 may have splines to engage corresponding splines around the central aperture.

[0035] The intermediate annular member 121 has an inner concave spherical surface 123 which is a spherical segment complementary to the outer convex spherical...

Abstract

A coupling (1, 2) has an inner member (111) and an outer annular member (131) and an intermediate annular member (121) that share a common axis when aligned and have a common center on the common axis. The inner member and the intermediate annular member are constrained to rotate one relative to the other about a second axis perpendicular to the common axis. The intermediate annular member and the outer annular member are constrained to rotate one relative to the other about a third axis (Z) perpendicular to the common axis (X) and to the second axis (Y). The members are spaced apart to leave a gap (103) between each of the members.

Description

technical field [0001] The invention relates to a shaft coupling. Background technique [0002] WO2015 / 087081 (Punk Couplings Limited) describes and claims a coupling having an inner member and an outer annular member and comprising: [0003] One or more pairs of annular members, which may or may not include one or both of an inner member and an outer annular member, each pair having a common axis and on said axis a first annular member and a second annular member having a common center; [0004] the first annular member has a convex spherical periphery; [0005] the second annular member has an inner concave spherical perimeter into which the outer convex perimeter of the first annular member is received; [0006] the outer convex perimeter and the inner concave perimeter are concentric about the center and are complementary to each other and cooperate with each other to transmit axial loads acting therebetween along the torsional axis; [0007] a shaft or a pair of dia...
