摘     要
 機(jī)油泵的功用是保證潤(rùn)滑油在潤(rùn)滑系中循環(huán)流動(dòng)，不能間斷，并在發(fā)動(dòng)機(jī)任何轉(zhuǎn)速下都能以足夠高的壓力供應(yīng)足夠量的潤(rùn)滑油。前者表明機(jī)油泵應(yīng)始終能吸到油，后者表明機(jī)油泵有壓力調(diào)節(jié)裝置。
 而傳統(tǒng)的汽車發(fā)動(dòng)機(jī)采取的齒輪式機(jī)油泵的缺點(diǎn)是需要中間傳動(dòng)機(jī)構(gòu)，體積大，制造成本較高，供油不均勻等。由于機(jī)油泵是內(nèi)燃機(jī)潤(rùn)滑系統(tǒng)的心臟，它的好壞直接影響內(nèi)燃機(jī)的可靠性和耐久性。因此對(duì)轉(zhuǎn)子式機(jī)油泵該課題的研究也將起到重大的意義。
 本論文介紹了對(duì)6105汽車發(fā)動(dòng)機(jī)轉(zhuǎn)子式機(jī)油泵的開發(fā)設(shè)計(jì)。而采用該機(jī)油泵能使機(jī)油泵在整個(gè)潤(rùn)滑系統(tǒng)里更好體現(xiàn)轉(zhuǎn)子式機(jī)油泵其本身結(jié)構(gòu)緊湊、吸油真空度高，泵油量大，效率高，供油均勻，成本低等優(yōu)點(diǎn)。本文在查閱了許多相關(guān)文獻(xiàn)資料并分析比較了國(guó)內(nèi)外現(xiàn)有對(duì)機(jī)油泵技術(shù)的研究的優(yōu)缺點(diǎn)基礎(chǔ)上，確定了該設(shè)計(jì)方案并進(jìn)行了相應(yīng)的結(jié)構(gòu)設(shè)計(jì)。
    本文通過對(duì)國(guó)內(nèi)外現(xiàn)狀的分析、方案設(shè)計(jì)、工作裝置的結(jié)構(gòu)設(shè)計(jì)以及零部件的設(shè)計(jì)與計(jì)算等多方面闡述了該新型機(jī)油泵的創(chuàng)新。

 Abstract
 The function of oil pump is to make sure that lubricating oil keeps circulating in the lubrication system without discontinue and to have a pressure high enough to provide sufficient lubricating oil under any rotation rate of the engine. The former of the two purposes indicates that the oil pump can absorb the lubricating oil all the time and the latter indicates that the oil pump has a pressure regulation device.
 With regard to the gear type oil pump that used by traditional automobile engine, there are some disadvantages such as needing an intermediate driving gear, huge volume, high producing cost, and inhomogeneity of oil supply, etc. What’s more, the quality of the oil pump, which is the heart of the lubrication system of the internal combustion engine, as a result, directly affects the reliability and durability of the internal combustion engine. Therefore, it is of great importance to have a study on the rotor oil pump.
 This paper introduces the development and design of the rotor oil pump of 6105 engine. When this kind of rotor oil pump is used, many advantages of the rotor oil pump can be exhibited in the whole lubricating system, such as the compact structure, high vacuum degree of oil absorption, large amount of oil pumping, high efficiency, homogeneity of oil supply, low cost, no particular requirement for assembly position, acceptability of being assembled outside the crankcase or relatively high places of the oil absorption position, etc. The author of this paper has consulted a lot of relevant literature and made an analysis as well as a comparison of the Pros and Cons of the oil pump technology at home and abroad, basing on which the design scheme is established and the corresponding structure design is conducted.
  This paper expounds the innovation of this new type of oil pump through the analysis of the current situation at home and abroad, the design scheme, the structure design of the work device, and the designs and calculates of the components and parts.
