Fourier Series Analysis of Epicyclic Gearbox Vibration
Epicyclic gears are used in many applications because they can achieve a large torque/speed ratio in a compact package. In most gearboxes, the estimated spectrum of the vibration signal is symmetric and centered at the meshing frequency. For epicyclic gears, the estimated spectrum is typically asymmetric and the dominant frequency component does not occur at the meshing frequency. This is an im...
متن کاملGearbox Noise and Vibration Prediction and Control
This paper will review practical techniques and procedures employed to quiet gearboxes and transmission units. The author prefers solving the gear noise problem at the very source to introduce an enclosure as a means to reduce radiated noise, which seems to be easy but its effect on the sound pressure level is small. The gearbox noise problem solution is focused on the improvement of gear desig...
متن کاملExperimental 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 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 کاملVibration Power Flow Analysis of a Gearbox Isolation System
Abstract—The power flow analysis of a gearbox isolation system is carried out in accordance with the structural characteristics of a gearbox. Numerical simulation is conducted to study the influence of major structural parameters on the power flow of a gearbox isolation system. The present research can provide a theoretical basis for the vibration isolation system design of a gearbox.
