Abstract
The invention relates to a method for producing cams (1) for a camshaft. The cams are produced by bending together the ends of long profile strips (4) or by bending and putting together several pieces of profile strips in a circumferential direction. Cams produced in such a way are preferably welded onto the shaft. The invention also relates to suitable welding methods such as resistance welding, laser-beam or electron-beam welding and corresponding devices.
Claims22
A method for producing a cam (1) for a camshaft which comprises a cylindrical shaft (2) and a plurality of cams (1) fixed on the latter, characterized in that the cam (1) is produced from at least one elongate profile strip (4) by the ends of the latter being bent together or from a plurality of profile strip pieces (30, 35) by these pieces being bent and assembled in the circumferential direction.
The method as claimed in claims 11 and 14, characterized in that the welding of the ends of the profile strip/profile strips (4;
- 30, 35) is carried out in such a way that the weld-seam recess (21) receives within it the welding bead which may possibly occur at the same time.
