<p>The machine has a connecting area formed by four regularly displaced spoke units between a bearing hub and an outer ring. The spoke units have rolling surfaces (13) for an insertable rolling body (14) which run in the form of a cut of a helical curve, where each surface exhibits a reverse orientation. A driving unit consisting of sub units (15A, 15B) is arranged for positioning on two sides of the spoke units. The sub units have rolling surfaces, which are counter surfaces to the rolling surfaces of the spoke units. The rolling body is connected as an intermediate element to the surfaces.</p> |
