摘要：

Herringbone gear is a key component in the reducer. Its mesh stiffness is an important parameter in gear dynamics research. In this paper, an improved Velex method is proposed to calculate the mesh stiffness of herringbone gears, and compared with Weber method and Finite Element Method (FEM), the accuracy of the method is proved. Meanwhile, the influence of helix angle and modification coefficient on the stiffness of the gear is analyzed by Weber method. The results show that the two parameters have different degrees of influence on the mesh stiffness of the herringbone gear, which provide a theoretical basis for the design of the herringbone gear transmission. Finally, by the calculation of the stiffness of the herringbone gear, the difference between the herringbone gear and the helical gear is compared and analyzed, and the conclusion that the herringbone gear is not a simple superposition of the helical gear is obtained. Because of the difference between the helical gear and the herringbone gear, it is of great value to the stiffness analysis of the herringbone gear.
