Accurate 3-D parameterized modeling and finite element contact analysis of involute X-gear pairs with tooth modification

Involute X-gear pairs with tooth modification are widely applied in many fields since they can increase the gear strength, improve the transmission quality, and obtain the large technical and economic benefits. A new method for creating their accurate 3-D parameterized models is developed in this paper. Using this method, the accurate 3-D parameterized model of a gear pair is created and its 3-D finite element contact analysis is performed. Analysis results state that the modeling method developed in this paper is simple and correct. Thus, for the involute x-gear pairs with tooth modification, the new modeling method simplifies their design procedure and lays the basis for their fine research of CAE/CAM and the optimization design.
