Abstract: A universal joint for shafting, and more particularly for rolling mills, with a device for suppressing pivoting of the joint is provided. For this purpose there is provided an axially yielding element, preferably in the form of a piston and cylinder unit driven by fluid pressure, in one joint fork. The device includes piston and cylinder unit which acts on an element which is connected with one of the other moving means of the universal joint. This other means can be either a rod secured to the other joint fork or a web-like plate between the bearing eyes of the other joint fork. It is also possible for the other movable member to be in the form of a rod, which acts through the crosspiece of the universal joint on a mating surface in the other joint fork. If the spherical surface is located on the crosspiece itself, there is then the possibility of preventing the free joint end from flopping downwards while nevertheless being able to pivot in a horizontal plane.

Abstract: A coupling for transmitting a torque from a shaft to a hub provided with an internal chamber which can be pressurized and which is relieved when a relative rotational movement takes place in relation to the shaft due to an overload and which is secured against slipping off from the shaft seat in an axial direction by a two-part flange mounted on the shaft. The flange engages with a radial groove in the hub in a claw-like manner and carries a shear-off device for breaking off the plug sealing the internal pressure chamber.
