【Abstract】 On the basis of principle of engagement this paper established a precise model of tooth profile.Taking this as a base,a finite element model of the whole gear plane was established,and the analytical calculation was advanced.The selection principle of model parameters has leen summarized according to the result of calculation while the finite element analysis was made on root stress of gear tooth.The 2D and 3D model formed under the selection principle have been calculated separately and a comparison is carried out on the calculated results of various models.The validity of the above mentioned principle was verified.更多还原
