Gearbox plays a vital role in a wide range of mechanical power transmission systems in
many industrial applications, including wind turbines, vehicles, mining and material handling …

Gearbox is widely used in industrial and military applications. Due to high service load,
harsh operating conditions or inevitable fatigue, faults may develop in gears. If the gear …

Considering the realistic spalling morphology obtained from the fatigue experiment, a novel
dynamic model for spalled gear pairs is established in this paper. Loaded tooth contact …

Dynamic characteristics of cracked gear systems, also known as cracked-gear rotor systems,
have received increasing interests among industry and academy in the past two decades …

Gear tooth crack will cause changes in vibration characteristics of gear system, based on
which, operating condition of the gear system is always monitored to prevent a presence of …

The main purpose of condition monitoring in gear systems is to facilitate condition-based
maintenance (CBM) by detecting the degradation of components, eg gear teeth, before the …

The occurrence of a crack could change the gear mesh stiffness and consequently influence
gear vibration properties. Cracks may occur on the tooth root and tooth surface, but the …

Fault classification methods are a long-term research focus in both science society and
engineering application. Generally, every real-world running mechanical system is exhibit …

As a result of gear body flexibility, fillet foundation stiffness is defined as the meshing force
needed for unit gear body-induced tooth deflections. However, it has long been …

Tooth faults affecting gear transmission are always accompanied by a stiffness reduction. In
this article an analytical method is proposed to quantify the reduction of gearmesh stiffness …
