Dynamics of simple gearing model with flexible planetary pins

摘要

The influence of flexible pins of planet gears on the dynamic properties of planetary gearing box is investigated by means of a general analysis with some alternative values of parameters. For discovering of basic dynamic behaviour of planetary gear system the simplest planetary gear set with neglected compliance of teeth contacts, fixed axes of central sun wheel and fixed planetary carrier, etc is used One mode of free vibration with eigenfrequency Ω proportional to k~(1/2) and zero frequency mode Ω→0 corresponding to the rotation with constant angular velocity were analysed. Forced vibrations, analysed by means of response curves, were oriented on ascertaining of influence of driving aggregate characteristic on frequency spectrum of the whole set.
