  • Patent number: 7765846
    Abstract: A method of producing a hollow shaft having first and second profilings provided for torque transmission at respective ends thereof, wherein a shaft section between the ends has a smaller diameter than at least one of the profilings, and the hollow shaft is assembled from hollow shaft and sleeve components joined via a torque-transmitting slip joint, in which the shaft and sleeve components are each formed from cut blanks by cupping, perforating. cold extrusion and turning steps, and the respective components are assembled to each other.

  • Publication number: 20080280691
    Abstract: A hollow shaft having improved profilings such as external splines, which are provided for torque transmission at its two ends, in which shaft sections between the profilings have smaller diameters than at least one of the profilings, and in which the hollow shaft is assemblable or assembled from two components, one of which components includes the shaft section and the profiling and at the end of the shaft opposite the profiling an external torque-transmitting profile of a slip joint, and the other component being a sleeve-like component with the second profiling at one end and an internal torque-transmitting profile of the slip joint at its other end, and method for producing the components and the assembled shaft.
