Air conditioning which uses in the compact car, due to receive harsh limit from the spatial size, as well as the engine power is relatively small and therefore pays attention to influence from the efficiency of the compressor, the external dimensions as well as the power loss and so on. In view of traditional compressor exist some insufficiencies, this design has studied a fixed-rotor compressor, and the ultimate characteristic of this compressor is the rotor adopts a fixed-rotation mode of operation, the relative speed between the main movements is smaller, and therefore its friction loss is very small following the completion of the design of the main areas of work. （1）A brief introduction of the automotive air conditioning refrigeration systems constitution and the principle of work, elaborated the development process of automotive air conditioning compressor, and has carried on the explanation to its special request, then focus on introducing structure and characteristics of the existing gleitbretter type and the vortex type compressors.（2）Focus more on the introduction of a fixed-rotor compressors design concept, the principle of work, and overall design.（3）To the fixed-rotor compressors several important components like air cylinder, the rotor, the rotation shaft, the fixed-vane, the rotation shaft bearing seat and the back-end cover has carried out the structural design, and has carried on the detailed analysis in the craft and the selection.（4）we have carried systemic design and analysis on suction exhaust system and lubrication system of the fixed-rotor compressor.（5）We have carried on thermodynamic analysis and the calculation to the fixed-rotor compressor, and have inferred the fixed-rotor and vanes kinematic and dynamic formula, meanwhile have carried on the transient equilibrium analysis to the rotor.Compares with the traditional vane compressor, this design compressor has much smaller relative velocity between the main movements such as the rotor and the cylinder, the rotor and the end cover, the vane and the cylinder hole, therefore it has the few friction and the attrition. Simultaneously, it also integration of vortex compressors translation machine together, takes its long, the equivalent cooling capacity higher than the existing compressor. Moreover the structure is compact, the external dimensions are small, the weight is light, and so it is especially for small vehicles.In the design process using AutoCAD, Pro / E and the Word, not only to learn the expertise, but also improve the ability of computer applications and broaden the knowledge.Key words Automobile air-conditioning compressor translation rotor structural design 目 錄摘 要IAbstractII第1章 緒 論11.1 汽車(chē)空調(diào)的歷程、意義和特點(diǎn)11.1.1 汽車(chē)空調(diào)歷程11.1.2 汽車(chē)空調(diào)的意義11.1.3 汽車(chē)空調(diào)的特點(diǎn)21.2 汽車(chē)空調(diào)制冷系統(tǒng)的構(gòu)成及其原理21.3 汽車(chē)空調(diào)壓縮機(jī)的發(fā)展歷程31.4 汽車(chē)空調(diào)壓縮機(jī)的特殊要求41.5 滑片壓縮機(jī)的結(jié)構(gòu)形式與特點(diǎn)51.6 渦旋壓縮機(jī)的結(jié)構(gòu)形式與特點(diǎn)61.7 本章小結(jié)7第2章 平動(dòng)轉(zhuǎn)子式壓縮機(jī)82.1 設(shè)計(jì)方案的提出82.2 研究的意義82.3 平動(dòng)轉(zhuǎn)子式壓縮機(jī)的工作原理92.4 平動(dòng)轉(zhuǎn)子式壓縮機(jī)的基本結(jié)構(gòu)102.5 平動(dòng)轉(zhuǎn)子式壓縮機(jī)的總體特點(diǎn)102.6 平動(dòng)轉(zhuǎn)子式壓縮機(jī)重要部件的設(shè)計(jì)112.6.1 缸體112.6.2 轉(zhuǎn)子122.6.3 轉(zhuǎn)軸132.6.4 平動(dòng)滑片142.6.5 轉(zhuǎn)軸軸承座和后端蓋152.7 本章小結(jié)16第3章 平動(dòng)轉(zhuǎn)子式壓縮機(jī)系統(tǒng)分析173.1 吸氣與排氣系統(tǒng)分析173.2 潤(rùn)滑系統(tǒng)分析183.3 本章小結(jié)18第4章 分析與計(jì)算194.1 熱力學(xué)分析與計(jì)算194.1.1 熱力學(xué)析194.1.2 熱力計(jì)算234.2 運(yùn)動(dòng)分析與計(jì)算264.2.1 平動(dòng)轉(zhuǎn)子運(yùn)動(dòng)分析與計(jì)算264.2.2 滑片運(yùn)動(dòng)分析與計(jì)算274.3 動(dòng)力學(xué)模型284.3.1 滑片受力分析284.3.2 轉(zhuǎn)子受力分析304.4 轉(zhuǎn)子的動(dòng)平衡計(jì)算314.5 本章小結(jié)32第 5 章 制冷劑、潤(rùn)滑油及附件335.1 制冷劑335.1.1 選用制冷劑時(shí)應(yīng)滿(mǎn)足的基本條件335.1.2 改用R134a時(shí)采用的措施335.2 潤(rùn)滑油的選擇345.2.1 選擇潤(rùn)滑油需滿(mǎn)足的要求345.2.2 選用R134a對(duì)潤(rùn)滑油的意義355.3 附件365.3.1 電磁離合器365.3.2 軸封及密封375.4 本章小結(jié)38結(jié) 論39參考文獻(xiàn)40致 謝41附錄1420第1章 緒 論1.1 汽車(chē)空調(diào)的歷程、意義和特點(diǎn) 1.1.1 汽車(chē)空調(diào)歷程汽車(chē)問(wèn)世已有一百多年的歷史。隨著生活水平的逐步提高，汽車(chē)已成為人們生活中的必需品，成為房間生活的延伸部分。對(duì)房間環(huán)境的要求同樣延伸到汽車(chē)上，空調(diào)便是其中一個(gè)重要內(nèi)容。汽車(chē)上安裝空調(diào)裝置的主要目的在于營(yíng)造一個(gè)舒適的環(huán)境條件1。汽車(chē)空調(diào)是從暖氣開(kāi)始的，最初是用煤炭腳爐取暖及把排氣管從車(chē)室內(nèi)通過(guò)。第一臺(tái)完整的汽車(chē)空調(diào)裝置出現(xiàn)在1927年，它包括一個(gè)加熱器、一套通風(fēng)系
