A friction drive mechanism, in which two axially displaced sets of rolling members (8) arranged in a common two-part holder (5, 6) are in external frictional engagement with a smooth shaft (4), the rolling members (8) being inclined relative to the shaft (4) to perform a rolling movement thereon by relative rotational movement between the holder (5, 6) and the shaft (4), the two holder parts (5, 6) being clamped together by a hinge joint (10, 11, 12) providing an automatical load-dependent bias and adjustment of the frictional engagement between the rolling members (8) and the shaft (4). |
