Abstract With the development of modern science and technology,the internal combustion engine has become the world's most widely used power plant。 In internal combustion engines, diesel engines play an important role in the engineering because of their outstanding economical performance and high power。 In the power plant based on diesel engines, transmission device ,as intermediate equipment of the transmission of power , is
dispensable to the system。 Its basic role is to deliver power from diesel engines to operating mechanism according to the request and to solve the problem about the power output characteristics of diesel engines。 In many engineering machinery, transmission device is the only way in which the power is leaded out from the power output。 Therefore, it is important for the whole transmission device to improve the transmission efficiency of the transmission device and to output the power in the form of what the power needs to be。 This topic is about the design of the transmission device of the diesel engines, mainly for the main complex parts of the transmission device, using UG NX 8。0, the 3D modeling software, to create the parametric 3D modeling, and to conduct virtual assembly according to the requirements of tolerance。
Keywords: internal combustion engine; transmission device; three-dimensional modeling
