Sažetak
The paper deals with the computing method of step shaft deflection in an intended place by using the diameter reduction method. This method is analytically studied on the selected shaft shape at different variants of diameters and individual span lengths, where values of deflection are compared with computed values without using this reduction. These values were selected as exact, which was verified by numerical computing in PTC Creo Simulate software. The relative percentage errors are graphically interpreted, and the contribution also deals with the creation of limiting conditions for their use. The aim is to point at limiting conditions of using this method, which may not be always met in practice. It also points to possible failures of this method, which is shown in an incorrect dimension of the shaft, influencing the reliability and safety of operation.
