Improvement on Meshing Stiffness Algorithms of Gear with Peeling [PDF]
Symmetry, 2019 This paper investigates the effect of a gear tooth peeling on meshing stiffness of involute gears. The tooth of the gear wheel is symmetric about the axis, and its symmetry will change after the gear spalling, and its meshing stiffness will also change during the meshing process. On this basis, an analytical model was developed, and based on the energy

On the evaluation of the meshing stiffness of external spur gears [PDF]
MATEC Web of Conferences, 2020 A comparison among different approaches of the meshing stiffness of spur gears has been carried out. The influence of each one on the load sharing, and subsequently on the determinant tooth-root and contact stresses, has also been studied. Equations for the evolution of the meshing stiffness along the path of contact according to all these formulations
