Vibration Analysis of Multistage Gear System Including Drive Mechanism Elements (2nd Report, Frequency Response Analysis of Helical Gear System)

An analysis method to predict the 3-dimensional vibration behavior of a multistage helical gear system is proposed. The method considers 6-degrees of freedom for each gear and introduces variables indicating the tooth deflection and the torsional angle between drive mechanism elements, i.e., couplings and a motor. The calculated and measured results for the helical gears and the torsional vibration of drive mechanism elements were compared. The calculated eigen frequencies and vibration responses agreed well with the experimental results. The usefulness of this method was shown.
