Abstract

Taking the planetary gear transmission system of wind turbine as the research object, considering the tooth shape error factor, established the translation-torsion dynamic analysis model, and analyzed the influence of each order error on the dynamic characteristics of the system. By solving the model, the time-domain history and frequency spectrum of the dynamic load of the system under different forms of errors are obtained, and the effects of different forms of errors on the dynamic load of the system, the floating trajectory of the sun wheel, and the system’s load-bearing performance are analyzed. The research show that after the sun wheel included in the tooth shape error, the system dynamic load fluctuation and the spectrum amplitude have obvious changes, especially the third-order error, when the load is small, the second-order error can appropriately reduce the system dynamic load, the first-order error significantly exacerbates the fluctuation of the dynamic load and greatly increases the radius of the sun wheel center floating trajectory, and has the greatest impact on the system’s load-sharing performance, the impact of the first-order error outside the involute on the dynamic characteristics is very small.
