Abstract: There is provided a tooth system for the static transmission of a torque between two machine components coaxially disposed in one another, e.g. a shaft and a hub, in which the tooth surfaces are straight and are designed with a very large pressure angle and with large tip and root fillet radii. The pressure angle of one component deviating slightly from that of the other component by half the torsion angle so as to overcome backlash. As a result, under load, the tooth surfaces abut over their entire surface. Also, the hubs can be produced with a smaller blanking indentation, in particular in the case of discs made of sheet metal, which increases the bearing capacity, and furthermore this can be done even more precisely, which results in an increase in centering precision and less noise generation during operation.

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.
