In order to improve the reliability of the gear transmission error of the wind turbine and the accuracy of the reliability analysis of the gear transmission error,the reliability analysis of the gear transmission error of the wind turbine based on the resistance characteristics is proposed.On the basis of introducing the dynamic parameters of the wind turbine gear transmission,the mean value of the stiffness of the gear transmission is calculated by cosine function fitting.On the basis of the schematic diagram of the tooth side clearance of the wind turbine gear,the tooth profile repair amount of the wind turbine gear is calculated,and the dynamic parameters of the wind turbine gear transmission are set.The resistance characteristics are applied to the displacement of the gear engagement direction of the wind turbine in the analysis,the manufacturing error,assembly error and deformation error of the gear are calculated respectively by calculating the displacement of the driven gear on the meshing line of the wind turbine.Finally,the reliability analysis of the gear transmission error of the wind turbine is realized through the reliability analysis process of the gear transmission error of the wind turbine.The experimental results show that the reliability analysis method of gear transmission error of wind turbine based on resistance characteristics has high reliability.
