Modeling and diagnostics of the gear power transmissions/ Krumpliniu pavaru modeliavimas ir diagnostika

This article presents experimental and theoretical research data based on mechanical vibrations of low speed rotor system (up to 40 rpm) with a gear transmission and double row spherical roller bearings with tapered bore. The rotor system experimental and theoretical modeling research analysis results confirm effective technical conditions monitoring and failures diagnostics method of low speed rotor system with antifriction bearings. The modeling and simulation acquired results generate determinations of residual operation time and service of gear transmissions and roller bearings. Authors presented a method of low rotation speed rotor vibration severity evaluation with validation data acquired by the experimental data of continuous long term running machine in situ.
