| Abstract | Gear pump with simple structure, high cost performance, reliable in performance is widely used in engineering machinery, agricultural machinery and so on. With the rapid development of modern science technology and industry, higher request are put forward to gear pump gear transmission. Therefore, the contacting strength problem of gear has become the focus of scholars at home and abroad and topics. In the process of gear meshing, the contacting strength calculation of gear become a complex nonlinear contact problem due to the tooth surface elastic deformation and nonlinear contacting load distribution. And contact problem belongs to the variable boundary problem. It makes contact analysis to be an iterative process because of the uncertainty of the border issue. Therefore, the traditional calculation method not only greatly increase the difficulty of the analyzed operation, also reduced the accuracy of the result. So the finite element analysis method for calculating the gear contact stress provides a new method and means. and the deformation and stress in the calculated have high credibility. In this paper, Based on gear engagement principle, the gear contact analysis and finite element analysis method, this paper introduced the use of static structural analysis modules in the ANSYS workbench. And there is an non-linear contact analysis of involute cylindrical gear meshing model through it. the gear is obtained under normal working stress deformation and stress. Comparing with the actual working condition, it is concluded that the direction of the gear can be optimized. |
