Abstract :
The tooth contact and load distribution of involute helical gears are investigated by means of finite element analysis (FEA) instead of traditional mechanical method. First, based on UG, the model created accurately is leading into Patran & Nastran. Secondly, the face-contact model of gears is established according to the deformation compatibility condition and force equilibrium relationship. Then the face-contact analog modeling is used to determine the dangerous cross-section and the worst load line according to the practical status. When the 300MPa face load is applied, the maximal bending stress is distributing near the root of the gear tooth where the worst load line appears, and the value of it is 208MPa. At last the result is advanced by the modal analysis and light-weight optimization. And the processing reduces the worst load. The result got by the method is more according with actual situation, and more dependable.
