Abstract:Based on the theory of concentrated parameters, a model for analyzing the static load sharing characteristics of herringbone planetary gear transmission system with floating composite ring gear was set up. And the static load characteristic behavior theory research of the system was studied. Time-varying mesh stiffness, eccentricity error incentive and center component floating were taken into consideration. The equilibrium equations of the system load were determined by the method of Fourier series. The behaviors of static load sharing characteristics affected by the system parameters including gear eccentricity error, center component floating form and quantity, torsional stiffness of the flexible ring gear were investigated qualitatively. The results show that the system load sharing coefficient increases with the increase of eccentricity error, and the effect of component eccentricity errors in combination on the system load sharing coefficient is greater than that of component eccentricity errors alone. The torsional stiffness change of flexible ring gear affects not only the floating quantity of sun gear and ring gear, but also the system load sharing coefficient. The herringbone planetary gear transmission system with floating composite ring gear has a better load sharing effect than the normal herringbone gear planetary gear system. © 2018, Central South University Press.
