Mechanism and Machine Theory, 2017
Abstract In previous works the authors presented two load distribution models for gears. One of the models was based on the rigid tooth assumption and the more complex of the two took advantage of influence coefficients obtained from a FEM model to find the load distribution.

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.

A Comparison of Gear Mesh Stiffness Modeling Strategies
2011Gearboxes are prone to numerous faults that require vibration health monitoring to ensure proper operation. Monitoring methods typically employ casing mounted accelerometers. This data is difficult to interpret because of the many gear mesh frequencies present and is further complicated by the presence of significant amounts of noise. Several different

Time-varying mesh stiffness calculation of cracked spur gears
Engineering Failure Analysis, 2014Abstract Considering the misalignment of gear root circle and base circle and accurate transition curve, an improved mesh stiffness model for a healthy gear pair is proposed and validated by the finite element method (FEM). Based on the improved method, three mesh stiffness calculation methods (method 1: straight lines for crack path and limiting ...

Meshing Stiffness Analysis of Gear Using the Ishikawa Method
Applied Mechanics and Materials, 2013Meshing synthesizing stiffness of teeth is the comprehensive effect of all teeth in the whole meshing region, which is related to elastic deformation of single tooth, comprehensive elastic deformation of a pair of teeth and overlap ratio of gear. This paper adopts Ishikawa method which is commonly used in the calculation of tooth deformation.

Dynamics of gear meshing: stiffness evaluation and vibration
2004In the present paper we are concerned with vibration problems in gears mesh. A 2D model is developed,which is able to create the teeth profile for the contact profile and the tooth fillet for a very large classes of 2Dgears. A single degree of freedom model is developed using lumped masses.
