Vibration analysis of a double-row planetary gear set considering the sun gear axial position [PDF]
Science ProgressDouble-row planetary gear set (PGS) is a common form of the PGS, which is relatively more complex than the regular PGSs. It consists of one sun gear, several long planets, several short planets, two ring gears, and one carrier.

A dynamic model for the planetary bearings in a double planetary gear set [PDF]
Mechanical Systems and Signal Processing, 2023 Double planetary gear sets (DPGSs) are widely applied to high power and high torque mechanical transmission systems due to the high loading capacity, steady transmission, and high transmission efficiency. Most previous works studied the planetary bearing vibration characteristics without the gear excitations. This work establishes a dynamic model for a

Application of flexible pin for planetary gear set of wind turbine gearbox. [PDF]
Sci Rep, 2022 AbstractWind turbines are eco-friendly energy sources that generate electricity from wind power. Among their various components, gearboxes constitute the most critical loss owing to their longest downtime. To guarantee their durability, a flexible pin was designed based on the original straddle-mounted pin for enhanced tooth load sharing and ...

Vibration Behavior of the Planetary Gear System by Considering the Fixed Output [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2023 This work studies on analytical model of the single–stage spur planetary gear in form of lumped–parameter model. It includes key nonlinear factors of planetary gear vibration such as mesh stiffness and backlash of meshing gears. The planetary gear set is

A Generalized Dynamic Model and Coupling Meshing Force Analysis for Planetary Gear Set Transmissions
Applied Sciences, 2022 The dynamics analysis of a planetary gear set transmissions requires the creation of completely different models for different gears, which is very tedious. In this paper, a generalized dynamics modeling process is proposed for a three planetary gear set

Dynamic modeling and vibration analysis of a cracked 3K-II planetary gear set for fault detection [PDF]
Mechanical Sciences, 2021 The 3K planetary gear system is a basic planetary transmission structure with many advantages over the 2K-H planetary gear system. However, the vibration characteristics will be more complicated due to the increase of central gears meshing with each ...

Quasi-Static Load Sharing Characteristics of a Planetary Gear Set with Planet Journal Bearings
Applied Sciences, 2020 The quasi-static load sharing characteristics of a planetary gear set with planet journal bearings are numerically investigated. The application of journal bearings instead of rolling bearings in planetary gear sets is an alternative to increase the ...

Modeling of Complex Planetary Gear Sets Using Power-Oriented Graphs [PDF]
IEEE Transactions on Vehicular Technology, 2020 In this paper, a systematic approach for the dynamic modeling of complex planetary gear sets is presented. The approach relies upon a set of rules for building the system matrices and vectors of the system full dynamic model for any planetary gear set. A congruent state-space transformation is applied to obtain a reduced-order rigid model of the system,

Vibration behaviour of stepped pinion type planetary gears
Nihon Kikai Gakkai ronbunshu, 2015 It is well known that the characteristics of exiting force of planetary gear mesh are varied with gear mesh phase between pinions in single pinion type planetary gear set and that the sideband phenomenon occurs in the sequentially phased planetary gear ...
