Investigation of the Dynamics of Gear Systems with Consideration of a Pinion Support Flexibility

The results of the study of gear systems dynamics with flexible pinion supports are shown in this paper. A periodic change of stiff meshed gears in elastic systems vibrates with all the natural frequencies and forms proportional differences in stiffness in the areas of the two pair and single-pair engagement. Parametric excitation in the elastic system with the gear wheels are made possible at resonance frequencies of excitation equal to an integer multiple of the number of times less than all frequencies of the system. It has been shown that the use of optimal multi-pith in the gear system reduces vibrations.
