摘要
Secured on one end face (20) of the camshaft (1) is the thicker end of a slightly tapered mandrel (2), which has a somewhat smaller diameter (D) than the camshaft (1). Feed passages (10) for oil under pressure end in the slightly tapered outer surface of the mandrel (2) in the region of its thicker end. The elastically expandable cam (9) to be mounted on the camshaft (1) is seated on an externally cylindrical sleeve (8), the inner surface of which has a slight taper equal to that of the outer surface of the mandrel (2). By feeding pressurised oil to the inner surface of the sleeve (8) via the passages (10) it is possible to expand the sleeve and the cam (9) elastically and to move them together in this state on the mandrel (2), as far as the end face (20). The supply of oil under pressure is then connected to the cam (9), allowing this to be expanded elastically on its own and, in this state, displaced onto the camshaft (1), away from the sleeve (8). The sleeve (8) forms a transport means for the cam (9) and facilitates the mounting of the cam since there is no longer a gap to disturb the pressure build-up between the cylindrical inner surface of the cam and the slightly tapered outer surface of the mandrel.
