Jixie chuandong, 2019 During the gears meshing process, the Time Varying Meshing Stiffness (TVMS) is affected by the relative displacement. An algorithm of TVMS considering two translational degrees of freedom is proposed. The algorithm is based on the potential energy method for the ideal involute spur gear.

Time-varying Meshing Stiffness Calculation of Spur Gears with Asymmetric Spalling Defects
International Journal of Mechanical and Electrical EngineeringGear systems are subjected to repeated loads during long-term operation, and factors such as insufficient lubricant to increase friction between gears, resulting in elevated temperatures and wear, are highly susceptible to tooth spalling. Tooth spalling is a common form of failure in gear failure.
