摘     要
 机油泵的作用是把机油送到发动机各摩擦部位，使机油在润滑路中循环，以保证发动机得到良好的润滑。所以它在润滑系统中，是一个可迫使机油泵油底壳送到引擎运动件的装置。
 内燃机广泛采用齿轮式和转子式机油泵。齿轮式油泵结构简单，加工方便，工作可靠，使用寿命长，泵油压力高。由于目前我国还是大量采用齿轮式机油泵，所以此次毕业设计不但将通过对齿轮式机油泵设计来加深对机械零部件设计软件的运用，扩展自己对实际生产研究的问题认识和分析解决，提高对问题的独立思考性和巩固在课堂上所学的理论知识，增强自己理论联系实际和举一反三的综合素质，而且将更加熟悉如何对齿轮式机油泵的结构进行深层次的改进研究和开发。
本次设计着重分析了机油泵的结构特征，工作原理以及研究方法，重点讨论了机油泵在生产和实际使用中将会要遇到的问题，比如：噪声，困油，漏油等实际问题。

Abstract
 Oil pump's function is delivers the machine oil the engine each friction spot, so that oil in the lubrication of road in the cycle in order to ensure that the engine be well lubricated. In the lubrication system so it is a force sent to the engine oil pump oil pan parts of device movement.
 The internal combustion engine widely uses the gear type and the rotor type oil pump. Gear-type oil pump has simple structure, easy to process, reliable, long life, high pressure oil pump. Because China is still a large number of used gear oil pump, so the graduation project will not only gear type oil pump designed to deepen the use of mechanical parts design software, to expand their research on the actual production of knowledge and analysis to solve problems, improve independent thinking on the issue and learned in the classroom to consolidate the theoretical knowledge and theory with practice and enhance their overall quality of replication, and will be more familiar with the gear-type oil pump structure of the improvement in depth research and development.
 This design analyzes the structure of oil pump, operating principles and research methods, focusing on the oil pump in the production and actual use will be problems, such as: noise, trapped oil, oil spills and other practical problems. .
 
Keywords：Gear  Oil Pump  Trapping oil  noise  oil spills
