A study of spur gear torsional mesh stiffness
International Technology and Innovation Conference 2009 (ITIC 2009), 2009Through applying finite element methods (FEM),the results of a detailed three-dimensional analysis of the torsional mesh stiffness of spur gears were presented in this paper. Hertz formula can only calculate the contact stress approximately, while FEM can be used to conduct precise analysis of the tooth contact stress and deformation.

Engineering Failure Analysis, 2021
Pitting is one of the fault forms of gears, which directly causes a reduction in gear time-varying meshing stiffness (TVMS). In this paper, the probability distribution model of gear TVMS is established with random pitting.

Vibration response and fault characteristics analysis of gear based on time-varying mesh stiffness
, 2020Gears are prone to failures, which are difficult to detect in the early stage. In this study, the time-varying mesh stiffness of gears teeth with different crack lengths is calculated, and the effects of spalling with different widths, lengths, and ...

Influences of friction and mesh misalignment on time-varying mesh stiffness of helical gears
Journal of Mechanical Science and Technology, 2017As 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.

Equivalent Conversion Calculation of Straight Bevel Gear Mesh Stiffness
2009 Fifth International Conference on Natural Computation, 2009Based on analyzing the defects of the usual equivalent conversion methods, the paper presents a new equivalent conversion method for mesh stiffness calculation of straight bevel gears of the small teeth number and diameter. By means of comparison among the different calculation methods, the conclusions can be obtained as follow: The straight bevel gear’

An Improved Model for Calculating the Mesh Stiffness of Helical Gears
Volume 10: 2019 International Power Transmission and Gearing Conference, 2019Abstract Time-varying mesh stiffness (TVMS) is one of the important internal excitations of gear transmission systems. Accurate solution of meshing stiffness is the key to research the vibration response of gear transmission system. In the traditional analytical method (TAM), the TVMS of single-teeth engaged region consist of bending ...
