Gearbox 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 کاملFourier 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 کاملProbabilistic Latent Component Analysis for Gearbox Vibration Source Separation
Probabilistic latent component analysis (PLCA) is applied to the problem of gearbox vibration source separation. A model for the probability distribution of gearbox vibration employs a latent variable intended to correspond to a particular vibration source, with the measured vibration at a particular sensor for each source the product of a marginal distribution of vibration by frequency, a marg...
متن کاملVibration Analysis Techniques for Gearbox Diagnostic: a Review
Gears are important element in a variety of industrial applications such as machine tool and gearboxes. An unexpected failure of the gear may cause significant economic losses. For that reason, fault diagnosis in gears has been the subject of intensive research. Vibration signal analysis has been widely used in the fault detection of rotation machinery. The vibration signal of a gearbox carries...
