TUBULAR CAMSHAFT FOR INTERNAL
COMBUSTION ENGINE
The current paper presents the results of the study to investigate the
possibility of replacing the conventional camshaft of an internal combustion
engine, with a hollow, tubular cross section camshaft.
In the conventional form the camshaft is stamped or forged, and made
of iron, having a full circular section. The proposed tubular camshaft is made
out of steel, and the cams are attached by shrinking-on the shaft. We have
considered three constructive variants of the tubular camshaft.
The strain state and the tensions of the classical camshaft and the
three constructive variations of the tubular camshaft were examined using the
finite element method.
