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 …

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 …

Time-varying mesh stiffness and gear transmission errors are the major excitations to gear
dynamics system. How to calculate them more accurately and efficiently has attracted much …

As an important part of reducers, herringbone planetary gear train (HPGT) has the
advantages of small size, small mass, large transmission ratio, compact structure and strong …

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 …

Focusing on gear transmission systems having thin web and hole structures for energy
saving and weight reduction, this work aims to propose an effective method for dynamical …

For the simulation of the tooth contact of helical gears, a precise determination of the length
of the line of contact is required, which is variable throughout the meshing cycle. This …

The meshing stiffness, load sharing ratio, and quasi-static transmission error of spur gear
pairs are related to each other and are dependent on tooth geometry. In addition, profile …

Considering the factors such as the nonlinearity backlash, static transmission error and time-
varying meshing stiffness, a three-degree-of-freedom torsional vibration model of spur gear …

Due to the lack of efficient formulas, fillet foundation stiffness under double tooth
engagement has long been a challenging problem for mesh stiffness calculation of spur …
