Vibration analysis of a double-row planetary gear set considering the sun gear axial position [PDF]

open access: yesScience Progress
Double-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]

open access: yesMechanical 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

Vibration Behavior of the Planetary Gear System by Considering the Fixed Output [PDF]

open access: yesInternational 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

open access: yesApplied 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]

open access: yesMechanical 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

open access: yesApplied 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 ...

Vibration behaviour of stepped pinion type planetary gears

open access: yesNihon 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 ...

Modeling of Complex Planetary Gear Sets Using Power-Oriented Graphs [PDF]

open access: yesIEEE 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,

A design of HDPE flexible spline of harmonics gear [PDF]

open access: yesMATEC Web of Conferences, 2018
In a design of a small robot, selecting a servo-motor is the most important method in designing process. Common miniature servo motors for small robots normally use conventional gear train set or planetary gear set.

Fault Diagnosis for a Multistage Planetary Gear Set Using Model-Based Simulation and Experimental Investigation

open access: yesShock and Vibration, 2016
The gear damage will induce modulation effects in vibration signals. A thorough analysis of modulation sidebands spectral structure is necessary for fault diagnosis of planetary gear set. However, the spectral characteristics are complicated in practice,
