ABSTRACT
Engine crankshaft is the most important and one of the most expensive parts, and its size affects the machining precision engine power, and to a large extent affect the engine performance and reliability, must be the correct choice in the processing of the processing line of the crankshaft in order to obtain a satisfactory technical and economic effects.
The design is a light vehicle order process to the preparation of the crankshaft, with the design and processing technology is the development of the crankshaft structure and materials and processing are the continuous development of means to determine the processing technology and design and fixturing programs, so as to achieve on the crankshaft in the Principle of operation of the engine operating conditions and the understanding of the crankshaft structure and a better understanding of further processing; known bad hair crankshaft size and standard size. Parts using CAD software, drawing maps, and then the use of Pro / E software to establish three-dimensional model, the preparation process of the crankshaft.
Keywords: Gasoline Engine;Crankshaft;Design;AutoCAD ;Pro/E.
