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.
