Damping is an important introduction in the study of gear system dynamics. Because the damping value of gear system meshing pair is related to many factors such as motion, lubrication and working conditions, its formation mechanism is more complex and needs to be further studied. Therefore, there is no accurate calculation formula for the calculation of gear system meshing pair damping, but in practice In the calculation, the empirical formula shown in the formula can be used for calculation
ζ — meshing damping ratio of gear pair, usually taken as 0.03 ～ 0.17; in this paper, ζ is taken as 0.07;
M1, M2 — gear quality.
