Abstract:
A dynamic analysis method is firstly presented to make up the present methods for calculating the strength of the cylindrical gear pair. The transient stress distribution and variation in the process of gear meshing can be obtained by dynamic simulation, the maximum bending stress, the maximum tooth contact stress and the corresponding worst meshing locations of the gear pair can be also accurately determined. Then the two key influence factors for gear strength calculation, load factor and contact stiffness coefficient, are deeply studied, and strength curves of gear pair with different load factor and contact stiffness coefficients are derived. Finally, comparative analysis between the proposed FEM method and traditional ISO method are performed. Analysis results show that the proposed method is more efficient and effective.
