Dynamic model of planetary gearbox with braked satellite-gear carrier
Půst, Ladislav ; Pešek, Luděk ; Radolfová, Alena
The report is focused on theoretical-numerical analysis of influence of flexible planetary pins and of planetary gearbox connection with external driving and braking aggregates. Introducing of the compliance of planetary pins and releasing of sun wheel requires complicated differential equations of motion containing new radial coordinates and negative radial stiffness of tooth mesh. Eigen-frequencies of separated gearbox and of three-aggregates-set are ascertain for different values of torsion stiffness of external aggregates. It was shown that there exist several multi-fold eigen-frequencies.
