Abstract:
1. A torsional coupler dimensioned for securement between an associated rotational motion source and an associated rotational motion target, said torsional coupler comprising: a first end component having an axis of rotation and a first component body, said first component body including: a second end component having an axis of rotation and a second component body, said second component body including a plurality of second lugs having a first side surface and a second side surface spaced peripherally from said first side surface, said plurality of second lugs disposed in circumferentially-spaced relation to one another about said axis such that a plurality of second recesses extend into said second component body with one of said second recesses disposed between adjacent ones of said second lugs; said first end component and said second end component being at least approximately co-axially aligned with one another as well as axially positioned and rotationally oriented relative to one another such that each one of said plurality of first lugs is at least partially received within one of said plurality of second recesses and each one of said plurality of second lugs is at least partially received within one of said plurality of first recesses and with said side surfaces of said plurality of first lugs being disposed in facing relation and co-extensive with said side surfaces of said plurality of second lugs; and, a plurality of force-transfer elements disposed between side surfaces of adjacent ones of said pluralities of first and second lugs such that rotational motion imparted on one of said first and second end components can be transmitted to the other of said first and second end components through said plurality of force-transfer elements in at least one direction of rotation about said axis.
