Abstract:
Cardan-type joint for providing a torsion-proof connection of two shafts with one another which is axially and/or angularly movable within certain limits comprising:flanges which are, in each case, arranged at ends of the two shafts connected by the joint,three driving pins axially projecting in the direction of the cardan-type joint on each of the flanges to provide six mutually staggered driving pins uniformly arranged on a circumference of a common graduated circle, anda flexible, regular polygon-type, joint ring which connects the driving pins with one another in a torsion-proof manner and which is provided with sockets at corner points, said joint ring being axially elastically deformable between the sockets,the joint ring being formed in several parts by a collar of several closed oval driving loops forming individual chain links, each winding around two adjacent sockets, and each of which can be radially swivelled on the sockets so that a shape of the joint ring can change in a flexible manner,wherein the oval driving loops are swivellably disposed in an axially slidable manner on the driving pins by pairs of mutually corresponding mutual contact surfaces, which have circular-arc-shaped contours in a meridian section, on the sockets and on the driving loops.
