Abstract: With mating process of gears and crossed vibration of shaft as well as the interaction between them the primary dynamic properties of a simple rotor-gear interactive system are analysed and discussed in relative detail. Some basic rules of the system on dynamic properties are discovered. The results of study show that both the two factors mentioned above and the interaction between them are of an important rule and not to be neglected for correctly analysing or learning the dynamic properties of a rotor-gear interactive system.

Key words: rotor, gear, dynamic property, vibration
