ABSTRACT:
A rotary elastic safety coupling for steel rolling mills comprises two coupling halves and an intermediate disk, elastic rubber components being provided in one of the coupling halves for absorbing shocks, while transmitting normal torques. A plurality of angularly equispaced wedge-shaped cantilever arms are attached to the intermediate disk. The cantilever arms have projecting portions which are received in respective wedge-shaped cavities on a driven coupling half. The projecting portions of the cantilever arms are flanked on both sides by the elastic shock-absorbing components, these components also being mounted in the cavities on the driven coupling half. The elastic shock-absorbing components are installed in a prestressed condition, whereby large rolling torques are transmitted without play upon reversals in the direction of force transmission. The intermediate disk, connected to the driven coupling half by the cantilever arms, is connected to a drive coupling half by fracturable safety pins.
