Abstract
A method for producing a constructed camshaft of an internal combustion engine may be used in connection with a camshaft having a cam, a shaft, and an anti-friction bearing. The method may involve machining the cam, machining the shaft to produce a setting region for arranging the cam, heating the cam and the anti-friction bearing, pushing the cam onto the shaft into a preliminary position and pushing the anti-friction bearing onto the shaft into a bearing position, equalizing a temperature between the shaft, the cam, and the anti-friction bearing by cooling at least the cam, and setting the cam onto an end position by way of pushing the cam onto the setting region.
Claims17
A method for producing a constructed camshaft of an internal combustion engine, the camshaft comprising a cam, a shaft, and an anti-friction bearing, wherein the method comprises:
- machining the cam, wherein machining the cam comprises grinding such that the cam is ready for use;
- machining the shaft to produce a setting region for arranging the cam;
- heating the cam and the anti-friction bearing;
- pushing the cam onto the shaft into a preliminary position, and pushing the anti-friction bearing onto the shaft into a bearing position;
- equalizing a temperature between the shaft, the cam, and the anti-friction bearing by cooling at least the cam;
- and
- setting the cam onto an end position by way of pushing the cam onto the setting region.
