A revised time-varying mesh stiffness model of spur gear pairs with tooth modifications

Mechanism and Machine Theory, 2018
Based on the thin slice assumption, a revised time-varying mesh stiffness (TVMS) model of spur gear pairs with tooth modifications is developed. The spur gear is divided into many individual slices along tooth width, and considering the revised fillet ...

A general contact stiffness model for elastic bodies and its application in time-varying mesh stiffness of gear drive

Mathematics and Mechanics of Solids, 2022
As a critical element of time-varying mesh stiffness (TVMS), contact stiffness of a gear drive has been defined based on simplified Hertzian contact stiffness or semi-empirical nonlinear Hertzian contact stiffness in previous works. This study proposes a general contact stiffness model for elastic bodies through piecewise linear interpolation of ...

A novel distribution model of multiple teeth pits for evaluating time-varying mesh stiffness of external spur gears

Mechanical Systems and Signal Processing, 2019
Tooth damage often causes gear mesh stiffness to decrease. Therefore, time-varying mesh stiffness (TVMS) can reflect the health condition of gears. A new two-dimensional Gaussian distribution model is proposed to simulate pitting distribution.

An improved analytical method for calculating time-varying mesh stiffness of helical gears

Meccanica, 2017
A “slice method” is adopted to calculate the time-varying mesh stiffness (TVMS) of helical gear pairs, where the tooth is divided into many individual sliced spur gears along the tooth width, and the TVMS of helical gear pairs is obtained by accumulating the TVMS of the sliced spur gear pairs.

Effect of Backlash on Transmission Error and Time Varying Mesh Stiffness

2021
Gears suffer by unavoidable time-varying mesh stiffness. Noise and vibrations amplitudes show the transmission error occurred within the components of power transmission error. The Gear Trax software has been used to model the gear with different amounts of backlash (from 0 mm to 1 mm by 0.2 mm increments) so that this gives a backlash due to the ...

Influences of friction and mesh misalignment on time-varying mesh stiffness of helical gears

Journal of Mechanical Science and Technology, 2017
As one of the most important excitation sources of vibration, time-varying mesh stiffness of helical gear pairs need accurately calculated. Compared with spur gears, friction in helical gears is significant. This work for the first time presents an improved calculation method for the mesh stiffness of helical gears with effect of friction incorporated.

Study of the time-varying mesh stiffness of two-stage planetary gear train considering tooth surface wear

Proceedings of the Institution of mechanical engineers. Part C, journal of mechanical engineering science, 2023
Due to the complex structure of the planetary gear train, the influence of early fault on the dynamic characteristics of the planetary gear train is complex and changeable.
