Modulation Sidebands of Planetary Gear Set
2013In this paper a torsional model of planetary gear set test bench is developed. This bench is composed by two identical planetary gears connected by a common shaft. A tri axial accelerometer is mounted in both rings. The mechanism leading to modulation sidebands is modelled. Time histories are characterized by a periodic fluctuation.

Response Sensitivity in a Nonlinear Planetary Gear Set
Volume 10: 2019 International Power Transmission and Gearing Conference, 2019Abstract Due to the wide range of speeds of the vehicle engine, the resonance cannot be completely avoided. Aiming at this problem, the analysis of the dynamic characteristics of the vehicle transmission system is transferred from the analysis of the intrinsic characteristics to the analysis of the dynamic response, and the sensitivity ...

Pinion Assembly Strategies for Planetary Gear Sets
Journal of Mechanical Design, 2013Previous works illustrate that the orientation of pinion run-out errors has strong effect on the load sharing behavior of floating planetary gear sets. To minimize the inequality of load sharing, an in-phase rule for assembling pinions is recommended by other researchers, while a theoretical proof is still lacking.
