Free vibration of planetary gearing
Original language description
Planetary gear drives have important advantages over parallel axis gears due to theirs compact design an great torque-to-weight ratio, but dynamic properties of such gearings are more complicated and they need deep dynamic analysis. For improving load sharing among planet wings, the application of flexible planetary pins or using free central wheel is needed. Presented paper is oriented on mathematical model design. The plane type of gearings with four planetary subsystems and fixed planet carrier has been selected. Used helical gearing has an essential smaller variation of contact stiffness against the direct spur gearings. Therefore this stiffness variability is not taken into account. Frequency and modal spectrums of such a dynamic mathematical model of planetary gearing set is presented and influences of design parameters are analysed.
