Rotary bodies, for example rotary tubes with ring bearings, present the problem of linking the rings (3, 4), that may also act as driving elements, to the tubular body (2) in such a way that variations in diameter of the tubular body due to thermal expansion are reliably neutralized. Using elastic support elements has the inconvenient of imposing on the elastic elements the weight of the filled tube, so that they have only a limited service life because of the constant change of load. By means of holding shoes (13) that are capable of moving in the radial direction in the ring (3, 4) and that bear against the tubular body (2), radial pressing forces can be applied on the holding shoes (13) through clamping elements (17) mounted on the ring (3) and movable in the circumferential direction, when the clamping elements (17) are clamped against the ring (3) by prestressable elastic elements (21). The arrangement is self-centering and the elastic elements are subjected to no change of load even with variations in diameter of the tubular body (2). |
