Abstract

The accuracy of revolving orbits of rotor axes in rotor systems with adaptive and sleeve sliding-friction bearings is analyzed in the paper measuring vibration dis-placements by contact less displacement transducers (straight measurement method) and vibration accelerome-ters (nonstraight measurement method). Experimental and theoretical research of rotor systems was performed. On the basis of received measurement results rotational orbits of rotor axes and other data formats necessary for analysis were formed. Reasons influencing the formation of irregu-lar form of rotor axes revolving orbits and dependencies between the research results of adaptive and sleeve sliding-friction bearings and the results received by measurement of the searched system by straight and nonstraight methods were defined.Analysis of the received results is made and con-clusions are presented about the diagnostic of revolution accuracy of rotor axes in rotor systems.
