The article presents measuring procedures and principles of determining deviations of shape and location of the crankshaft main necks assembly axis. We also described mathematical methods of roundness shapes description based on the harmonic analysis theory for the cases when the shaft is set with the external journals in prisms and for the case when the shaft is set on the external front faces in the claws. The results of sample calculations realized on the basis of the proposed mathematical methods have been presented in a form of diagrams of so called amplitude spectrum and in a graphic form of roundness shapes expressed in a polar coordinate system. The procedures described find a practical use during measurements of geometrical deviations of crankshafts realized on the basis of a measuring system with so called flexible support of the measured object.
