Experimental Analyses of Vibration and Noise of Faulted Planetary Gearbox
ABSTRACT Epicyclic gear trains are widely used in various industrial sectors due to their advantages over fixed-axis gears, such as high torque capability, compact size, differential and planetary designs, ease of adjusting gear ratios and even directions of rotation. This research focuses on planetary gearbox whose degree of freedom is one. The geometry and dynamics of the planetary gear train...
متن کاملPlanetary gearbox fault diagnosis using an adaptive stochastic resonance method
Planetary gearboxes are widely used in aerospace, automotive and heavy industry applications due to their large transmission ratio, strong load-bearing capacity and high transmission efficiency. The tough operation conditions of heavy duty and intensive impact load may cause gear tooth damage such as fatigue crack and teeth missed etc. The challenging issues in fault diagnosis of planetary gear...
متن کاملMisalignment Diagnosis of a Planetary Gearbox Based on Vibration Analysis
As a critical power transmission system, planetary gearbox is widely used in many industrial important machines such as wind turbines, aircraft turbine engines, helicopters. Early fault detection and diagnosis of the gearbox will help to prevent unexpected breakdowns of this important equipment. Misalignment is one of the major operating problems in the planetary gearbox which may be caused by ...
متن کاملA New Fault Diagnosis Method for Planetary Gearbox
Abstract–Planetary gearbox is widely used in many fields due to its robustness and high power-weight ratio, but implementation of fault diagnosis on it is challenging. This paper proposes a new fault diagnosis method for planetary gearbox based on empirical mode decomposition (EMD) and adaptive multi-scale morphological gradient filter (AMMGF). The proposed method has two dominant strengths: it...
متن کاملResearch on vibration and acoustic radiation of planetary gearbox housing
In this paper, an analysis model of planetary gearbox housing is constructed based on finite element method/boundary element method (FEM/BEM). Its vibration and acoustic radiation characteristics are investigated. Firstly, the finite element model is established using ABAQUS. The main factors affecting its dynamic characteristics are observed through modal analysis. Then impact of main structur...
