Keywords: assemblyprocess; visualizationassemblycoalingmachine; design0 introduction to the method of calculating the entire life cycle of mechanical products in a variety of process visualization optimal design method is a digital design approach that emphasizes the design process throughout the full application of computer technology, machines and systems modeling, functional simulation and process simulation. As the quality requirements of mechanical product design continues to improve, more and more visual design optimization applied to product design. Visual optimization design, we can see from Table 2, the first one kind of loading (ie load on the tooth tip), the standard for involute spur gear and the calculated results in [6] calculated the maximum difference 1.82MPa, that build the ANSYS model is accurate. Therefore,[link widoczny dla zalogowanych], the first two kinds of loading (see Figure 7) finite element model should be accurate,[link widoczny dla zalogowanych], the results can be regarded as accurate. 5 Conclusion (1) applications into the UG software under the scope of the principle can create accurate three-dimensional geometry of involute gear model, and the tooth involute without transition curve equations. (2) finite element model constructed for the high precision gear transmission (6 and above) or modified gear drive,[link widoczny dla zalogowanych], get a more accurate maximum stress in the tooth root bending. (3) In this paper, the tooth root bending stress finite element model building method, with generating method can be applied to processing of helical gear tooth root accurate calculation of the maximum stress.
