摘要： A method of manufacturing a camshaft for an engine having cylinder head bolts, includes providing a tube, placing at least one separately produced cam in a position on the tube along an axis of the tube, fastening the cam to the tube and pressing at least one external indentation into the tube at a part of the circumference of the tube. The indentation is pressed transversely toward the tube axis into inner and outer surfaces of a wall thickness of the tube at an axial location along the tube axis and does not encircle the tube. The indentation is also disposed along the tube and beside the cam with no part of the indentation being covered by the cam and the indentation being sufficiently deep to allow access to the cylinder head bolts of the engine.

摘要： Camshaft configurations are increasingly more closely assembled in motor vehicle engines such that access to the cylinder head bolts is obstructed. Indentations 2 along built-up camshafts, which comprise a camshaft tube 1 with slid-on camshaft structural components, such as the cams 3, permit through corresponding rotation free access to the cylinder head bolts even after they are in the installed state. In order to be able to employ for the camshaft structure tubular camshafts 1, according to the invention a pressing tool 10 with bottom dies 12, 13 is provided such that during the pressing operation of the indentations, the camshaft tube 1 advantageously is not deformed beyond the original outer diameter d and the camshaft 1 can be assembled advantageously form-fittingly through subsequent sliding-on of the cams 3.
