Abstract

A polygon compensation coupling system (30; 40; 60) comprises a first rotatable element (31; 41; 61), a second rotatable element (32; 42; 62a, 62b), and at least one linkage coupling the first rotatable element (31; 41; 61) with the second rotatable element (32; 42; 62a, 62b). The linkage comprises at least one first coupling element (34a; 44a; 64a) pivotably coupled to the first rotatable element (31; 41; 61) and at least one second coupling element (34b; 44b; 64b) pivotably coupled to the second rotatable element (32; 42; 62b). The first and second coupling elements (34a, 34b; 44a, 44b; 64a, 64b) are pivotably coupled to each other at a hinge point, the hinge point is configured to move along a compensation curve varying the coupling between the first rotatable element (34a; 44a; 64a) and the second rotatable element (32; 42; 62b).
