A rotary connection for cranes, wind power plants, solar panels and the like, having an outer ring (1) and having an inner ring (2) which are arranged so as to be rotatable relative to one another, and also having a rotary drive (5). An inexpensive rotary drive, which takes up little installation space, for the rotary connection is attained according to the invention in that the rotary drive (5) is arranged within the inner ring (2) and acts on the inner ring (2) via a wraparound element (7; 17, 18). Without departing from this design principle, it may also be provided that the rotary drive is arranged within the outer ring (1) and acts on the outer ring (1), which is to be rotated, via a wraparound element. The wraparound element may be a flexible tensile element (7), for example a cable, a flat belt or a chain, or else may be a thrust element (17) which is flexurally rigid in a transverse direction, for example a thrust belt, a thrust chain or a thrust link belt. |
