The front integrated transmission chain has become the main technical route of wind turbines,and the main shafting has a prominent impact on the first stage planetary gear train.Taking the transmission chain of a medium speed permanent magnet wind turbine as the research object,an integrated model of the hub,main shafting,and first stage planetary gear train was established.Load was applied to the center of the hub,and simulation analysis was conducted to studied the influence of main shafting deformation on the meshing of the first stage planetary gear train,and further carried out gear micro modification design and experimental research.Research has shown that the micro modification plan of the gear teeth in this article can significantly improve the bias load of the first stage planetary gear train,reduce the impact of the main shafting deformation on the mes-hing of the first stage planetary gear system,and provide a reference basis for the parameter design of the wind power gearbox planetary gear train and the micro modification of the gear teeth.
