Gears are an important component of industrial machinery and a breakdown of machinery
on account of the failure of gears could result in immense production loss. Timely monitoring …

Affected by external flexible transfer path of fixed-shaft gear train, internal gear meshing
vibration signals that representing the healthy state of gear will convolve with modal …

The vibration signal of the planetary gearbox shows complicated modulation sidebands no
matter the gear is normal or fault. It leads to a challenge in the fault diagnosis, especially for …

This paper proposed a dynamic model based on the lumped parameter method and the
Timoshenko beam theory to explore the sideband distribution law of the coupled bevel gear …

Amplitude modulation (AM) in planetary gears, arising from rotation of carrier, is a
predominant phenomenon that yields unique yet complicated dynamic behavior. However …

A thorough understanding of the formation mechanism of modulation sidebands in the
vibration spectra is helpful to the condition monitoring and fault diagnosis of epicyclic …

Planetary gearbox is one of the most important components of rotating machinery and plays
a key role in modern industry. Due to the complex physical structures and harsh working …

This work investigates the vibration properties of planetary/epicyclic gears that arise from
their cyclic symmetry. All results are derived without use of a specific mathematical model; …

Abstract Model-based vibration signal analysis to interpret and understand vibration
characteristics can provide prior guidance for the condition monitoring and fault diagnosis of …

With a focus on high-speed, lightweight planetary (or epicyclic) gears, this work develops an
analytical dynamic model with the sun, carrier, and planets modeled as rigid bodies coupled …
