| Abstract: | The accelerator is the key component of wind power equipments.Its transmission mode is mostly compound planetary gear train.The contact stress of planetary gear train affects the performance of the accelerator.A 5.5 MW speed-increasing box with power-splitting planetary differential structure was designed.The model of low-speed helical planetary gear train was simplified by UG.A rigid-flexible hybrid finite element model was established by ANSYS Workbench.Reasonable kinematic pairs and contact relations were set up.Transient contact dynamic analysis was completed.The calculated contact stress was analyzed and compared with the allowable stress value of 850MPa.Results show that the structure design of planetary gear train meets the requirements. |
