Research on Time-Varying Meshing Stiffness of Helical Gear Considering Tribo-dynamic Behavior

2018 9th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2018
An analytical expression of oil film stiffness is proposed for helical gear based on two-dimensional EHL analysis considering the dynamic force, rotational speed, tooth blank temperature and oil viscosity. Then the tribo-dynamic equation is built to obtain the time-varying meshing stiffness of helical gear.

Dynamic Simulation of 2K-H Differential Gear Train with Time-Varying Meshing Stiffness

Advanced Materials Research, 2011
Taking 2K-H differential gear train as study object, dynamic equation of torsion vibration was established with influence of time-varying meshing stiffness. The virtual-prototype with nonlinear meshing force was modeled using Virtual.Lab Motion software. Gear contact force was simulated, and it was verified by theoretical data.

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.

Nonlinear dynamic of a spiral bevel gear pair with time-varying mesh stiffness

2017
Bevel gears are one of the most important components of mechanical system to transmit motion between intersecting axes. For high-speed power transmission, spiral bevel gears are more useful instead of straight bevel gears. One of the main sources of vibration and noise of bevel gears, are oscillations of transmission error. Vibration Analysis of a gear
