ABSTRACT:
A camshaft for controlling valves in internal combustion engines includes a shaft and at least one cam slid onto and connected to the shaft. The cam has a recess for receiving the shaft. The recess has at least one radially inwardly directed projection which engages a corresponding groove in the shaft. At least one portion of the area of the shaft in which the cam is to be provided has a diameter which is greater than the remaining areas of the shaft. The increased diameter portion of the shaft is a bead-like material displacement which extends circumferentially on the shaft and is manufactured by rolling. The cam is forced onto the increased diameter portion of the shaft with a projection in the recess of the cam forming in a chip-removing operation a groove in the increased diameter portion.
