摘     要
 機油泵的作用是把機油送到發(fā)動機各摩擦部位，使機油在潤滑路中循環(huán)，以保證發(fā)動機得到良好的潤滑。所以它在潤滑系統(tǒng)中，是一個可迫使機油泵油底殼送到引擎運動件的裝置。
 內(nèi)燃機廣泛采用齒輪式和轉(zhuǎn)子式機油泵。齒輪式油泵結(jié)構(gòu)簡單，加工方便，工作可靠，使用壽命長，泵油壓力高。由于目前我國還是大量采用齒輪式機油泵，所以此次畢業(yè)設(shè)計不但將通過對齒輪式機油泵設(shè)計來加深對機械零部件設(shè)計軟件的運用，擴展自己對實際生產(chǎn)研究的問題認識和分析解決，提高對問題的獨立思考性和鞏固在課堂上所學(xué)的理論知識，增強自己理論聯(lián)系實際和舉一反三的綜合素質(zhì)，而且將更加熟悉如何對齒輪式機油泵的結(jié)構(gòu)進行深層次的改進研究和開發(fā)。
本次設(shè)計著重分析了機油泵的結(jié)構(gòu)特征，工作原理以及研究方法，重點討論了機油泵在生產(chǎn)和實際使用中將會要遇到的問題，比如：噪聲，困油，漏油等實際問題。

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
