The camshaft for internal-combustion engines is assembled from the prefabricated shaft (1) and the prefabricated, preferably sintered, cams (2). In the region (C), in which the cam (2) is to be mounted on the shaft (1) such that it cannot rotate, the shaft (1) is broadened. This is carried out, without cutting the metal, by rolling circumferential beads or raised areas on the tube or the shaft, as is known from the manufacture of threads. Projections (5) are provided in the recess of the cam (2). When the two parts are pushed together, the projections (5) act like a plane and metal is removed to form a corresponding slot, so that, when the cam (2) is completely installed, there is a force-fit and positively locking connection, with a high retention force, between it and the shaft (1). …<IMAGE>… |
