According to the characteristics of the helical gear round and related parameters, in UG software to establish correct 3 d model, and will build the model into ANSYS analysis software analysis to study the characteristics of the meshing thermodynamics. Driving gear in the process of work b y periodic load of forces, may have occurred within the strong calibration speed resonance, dynamic stress increase sharply, cause premature fatigue and reverse gear bending fatigue. By using the finite element analysis software ANSYS gear tooth root stress and gear contact analysis calculated, two size of gear contact temperature distribution in the cloud. The calculated results are accurate, intuitive, and for the round the helical gear contact thermal analysis and strength check provides a rapid and effective method. In the application of finite element analysis software ANSYS large, focus on the gear engagement by the deformation, change the coincidence degree, transmission ratio change. This paper introduces the analysis method of ANSYS contact, and on one of them to meet the contact, the article discusses the calculation process of may affect the convergence of factors: deal with the method of interface restriction, friction model, the contact strength, initial contact conditions of the selection and simulation remendation, a numerical example is given to illustrate the finite element analysis of the problems in gear contact on effectiveness. For other types of contact problem analysis provides reference.
