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.

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;
- 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.
An anti-friction bearing for use in connection with a constructed camshaft having a cam and a shaft, the anti-friction bearing comprising:
- an inner ring;
- an outer ring;
- and
- a projection that extends in a radial direction on an end side of at least one of the outer ring or the inner ring so as to prevent an axial displacement between the inner and outer rings.
