Abstract
A shaft, such as a camshaft for use in the internal combustion engine of a motor vehicle, in which the shaft includes a basic shaft body, a plurality of functional bodies, such as cams, mounted in axially spaced positions on the basic shaft body, and at least one balancing element mounted on the basic shaft body, in which the at least one balancing element is produced separately from the basic shaft body and from the functional bodies, and the functional bodies and the at least one balancing element are subsequently mounted on said basic shaft body, for example, by axial press fitting.
Claims2
A method for producing a non-circular functional body for press fitting onto a shaft, said method comprising:
- deforming the functional body into a state corresponding to deformations which arise when the functional body is press fit onto the shaft;
- grinding the functional body to a specified configuration while the functional body is in the deformed state;
- releasing the ground functional body from the deformed state, whereby the functional body departs from the specified configuration;
- and
- press fitting the functional body onto the shaft, whereby the functional body reassumes said specified configuration.
