Theoretical Vibration Analysis Regarding Excitation due to Elliptical Shaft Journals in Sleeve Bearings of Electrical Motors
Figure 9
Absolute orbits of the shaft centre point , of the shaft journal points and and of the bearing housing points and , described by (a) the semi-major axes, (b) the semi-minor axes, and (c) the angles of the semi-major axes. (d) Definition of the absolute orbits. Boundary condition: identical orientation of the elliptical shaft journals () and different rotor speeds.
