A method for improving a corrosion protection of a hollow shaft may include introducing a lance into the hollow shaft, and cleaning and expelling a liquid from an inside of the hollow shaft via spraying a gas from the lance. The method may also include applying a corrosion protection medium onto an inner lateral surface of the hollow shaft at least in certain regions, and closing off the hollow shaft.

Method of improving a corrosion protection of a hollow shaft

A device for mounting at least one receiving element on a shaft may include at least one holder for holding a receiving element having a cut-out for receiving a shaft. A moveable guide slide may be configured to move the shaft in a first direction through the cut-out in the receiving element. A tailstock may be configured to move counter to the first direction. The tailstock may include a tailstock tip configured to couple to an end face of the shaft. A vibration generator may be arranged in the tailstock for vibrating the shaft.

Device for mounting at least one functional element having a cut-out for a shaft

A camshaft for an internal combustion engine may include a shaft and at least one component that is joined to said shaft. The component may be connected via a joint surface of the component to a joint surface of the shaft. At least one of the joint surface of the component and the joint surface of the shaft may have a predefined roughness only partially on load-critical regions.

Camshaft and corresponding production method

A camshaft for an internal combustion engine may include a shaft and at least one component thermally joined thereto. The at least one component may be connected via a component-side joining face to a shaft-side joining face of the shaft. At least one of the component-side joining face and the shaft-side joining face may include a predefined roughness introduced and hardened via a laser. The predefined roughness may define at least one track composed of a plurality of individual laser spots. Each of the plurality of individual laser spots may include a center point arranged offset to each other. The plurality of individual laser spots may respectively be arranged to overlapping each other.
