| description | According to the requirements of a spacecraft,a double input planetary reducer is designed,and the most loaded gear is checked using traditional methods and finite element software. Due to the existence of a large axial force,the finite element strength check and axial stiffness check of the reducer box are completed. Bearing capacity test and axial stiffness test of the reducer is completed to verify the correctness of the check. The traditional gear root strength checked method is based on the beam theory of mechanics of materials.The gear teeth are treated as cantilevers with unidirectional tension or compression,but actually,each element is in three dimensional state of stress. The Von-Mises equivalent stress obtained by finite element method,which is based on the fourth strength theory,can better serve as a check criterion. |
