ABSTRACT
2100 diesel engine is China's own mature diesel model, conventional medium power, have such conditions and development. At present, a large area has been used in the agricultural engineering machinery in China, civil power and other fields. Comparison of 2100 diesel engine with similar models, with excellent power performance, economy and reliability, has a strong advantage in the domestic agricultural machinery users in the market now, mainly in the 2100 diesel engine crankshaft, piston and rod assembly, fuel system optimization, strengthening the design of than the old models, so that the engine has a larger to improve the power, economy and other aspects, also achieved the purpose of increasing its scope of application.
This paper mainly discusses the design process of 2100 diesel engine crankshaft system. Including 2100 diesel engine crankshaft, pulley, gear, parameter selection of drawing crankshaft flywheel parts drawing, machining process and product inspection and strength check etc..
This paper uses the SolidWorks software for 3D graphics, crankshaft flywheel group design problem in this paper is studied.
Keywords: diesel engine, crankshaft, flywheel, timing gear SolidWorks
