【正文】 齒輪泵由曲軸直接驅動，無需中間傳動機構，所以零件數(shù)量少，制造成本低，占用空間小，使用范圍廣。其外齒輪是主動齒輪，套在曲軸前端，通過花鍵由曲軸直接驅動。（2）內接齒輪式機油泵內嚙合齒輪式機油泵也稱內接齒輪泵，其工作原理與外嚙合齒輪式機油泵或齒輪式機油泵相同。齒輪式機油泵又分內接齒輪式和外接齒輪式，一般把后者稱為齒輪式機油泵。汽車發(fā)動機潤滑系統(tǒng)的組成工作原理及現(xiàn)實意義圖2 1發(fā)動機潤滑系統(tǒng)的組成 機油泵圖2 2機油泵機油泵的功用是保證機油在潤滑系統(tǒng)內循環(huán)流動，并在發(fā)動機任何轉速下都能以足夠高的壓力向潤滑部位輸送足夠數(shù)量的機油。此外，為了避免發(fā)動機磨損，還要合理的使用汽車發(fā)動機養(yǎng)護品。汽車發(fā)動機潤滑系統(tǒng)的維護是非常重要的，潤滑系統(tǒng)的正確、可靠，對汽車發(fā)動機的性能、使用壽命都有幫助。因此，潤滑是保障汽車正常運行的重要因素。固體之間接觸的表面用肉眼看似乎很平整，但將表面極細微部分放大就會發(fā)現(xiàn)處處是凸凹不平，所以一運動就會有摩擦。汽車發(fā)動機潤滑系統(tǒng)的發(fā)展將會在一次迎來一場新的變革。關鍵詞 ：潤滑系統(tǒng)，故障，檢測，維修The engine lubrication system is the basis to ensure normal engine operation. The basic task of the lubrication system is the lubricant continuous supply various parts of the friction surface so that lubrication, reducing friction and wear of the parts. Lubrication System not to participate in engine function of conversion, but it can ensure that the engine, it has a longer service life. About the engine lubrication system failure analysis testing and maintenance, let us know the position and function of the engine lubrication system, and the lubrication system Common symptoms of the fault location, fault mechanism, failure analysis testing and maintenance and fault exclusion a certain amount of understanding, clear the basic idea of the analysis of detection and diagnosis. Theory with practice and mon position and function of some car engine lubrication system and fault detection and for the maintenance of the corresponding notes. With the development of vehicle technology, more and more plex structure of the car, we only have to acquire more knowledge and practical experience in order to make better use of testing instruments quickly and accurately find the cause of the malfunction of the car, and troubleshooting.Keywords: lubrication systems, fault detection, maintenance.第一章 序言汽車發(fā)動機潤滑系統(tǒng)是省工降費、安全高效環(huán)保、延長車輛壽命”的科學工作特點和良好潤滑效果，在汽車行業(yè)已經(jīng)得到一定程度普及份和應用良好的發(fā)動機潤滑系統(tǒng)具有潤滑、冷卻、防銹及去污等功能。通過理論與實際結合以及對一些汽車發(fā)動機潤滑系統(tǒng)的常見組成和功用及故障檢測與為維修做了相應說明。潤滑系雖然不參加發(fā)動機功能轉換，卻能保證發(fā)動機正常工作，使其具有較長的使用壽命。畢業(yè)設計（論文）摘 要發(fā)動機的潤滑系統(tǒng)是保證發(fā)動機正常運轉的依據(jù)。潤滑系的基本任務就是將潤滑油不斷地供給各零件的摩擦表面使其潤滑，減少零件的摩擦和磨損。通過對發(fā)動機潤滑系故障的分析檢測和維修的講述，讓我們知道發(fā)動機潤滑系統(tǒng)的組成和功用，并對潤滑系的常見故障現(xiàn)象，故障部位，故障機理，故障的分析檢測和維修及故障排除有了一定的認識，明確了分析檢測和診斷的基本思路。隨著汽車科技的發(fā)展，汽車的結構也越來越復
