摘 要

空調壓縮機是空調系統的核心部件。從空調壓縮機的發展趨勢來看，結構緊湊、高效節能以及微振低噪等特點是空調壓縮機制造技術不斷追求的目標。另外汽車空調的普及，是提高汽車競爭能力的重要手段之一。隨著汽車工業的發展和人們物質生活水平的提高，人們對舒適性，可靠性，安全性的要求愈來愈高。因此，本論文

將重點針對翹板活塞式汽車空調壓縮機進行研究與設計。

本論文詳細介紹了翹板活塞式汽車空調壓縮機的基本構造及其工作原理,以及其設計方法。首先，對汽車空調壓縮機作了簡介；然后，對汽車空調壓縮機的理論基礎以及翹板活塞式空調壓縮機的結構設計進行了說明，包括電磁離合器的構造和工作原理，再將其和斜板式壓縮機做比較。接著，對翹板活塞式壓縮機進行了結構設計以及工藝分析。最后，結合所做的研究對翹板活塞式壓縮機容易出現的故障提出合理的診斷與維修方法。

研究與設計表明翹板活塞式汽車空調壓縮機具有以下特點：整體鑄造成型、制造成本低、工作噪音低、裝置振動小。另外，連桿與翹板通過鉸接球相連，這讓活塞往復移動時能夠帶動連桿運動。翹板在主軸的帶動下轉動，而且連桿隨翹板的旋轉而在一定的范圍內翹動，活塞的外圍表面抵住氣缸內表面，以停止連桿的轉動，翹板的轉動也因此停止。

翹板活塞式汽車空調壓縮機有很多顯著的特點：首先，其便于在發動機上安裝和傳動；其次由于氣缸圍繞主軸中心的圓周布置，可使結構緊湊，易于實現小型化和輕量化；采用多缸工作，動力平衡性能好，運轉平穩；排氣均勻，驅動力矩變化??；設計和生產工藝成熟，結構較為完善。

關鍵詞：翹板式壓縮機，結構設計，工藝分析,故障診斷

Abstract

Air conditioning compressor is the core part of air conditioning system.From the development trend of air conditioner,closely-knit,high-efficient,energy-saving,low vibration and noise are the consistent goals of air conditioning compressor.In addition, the widely used of automotive air conditioners is an important method to improve competivness. With the development of car industry and living standard of people, there is an increasingly higher demand for comfort, reliability, security. Therefore, this paper aims at the study and design of the wobble plate compressor.

This paper gives a detailed introduction of the configuration and working principle of the wobble plate compressor, as well as the way in which it is designed. First of all, this paper presents a brief introduction of the air conditioning compressor, particularly the analysis of configuration and working principle of wobble plate compressor, including the structure and working principle of the electromagnetic clutch. Then, make a comparision with swash type compressor. Finally, concluding the common malfunction and maintenance methods from the study.

The invention provides an wobble plate compressor formed in a simple structure, manufacturable at low cost, and having a low noise and low vibration wobble plate rotation stopping mechanism. This wobble plate compressor comprises a spindle rotatingly driven by a drive source, an wobble plate oscillated according to the movement of the spindle, pistons connected to the wobble plate through connecting rods, and cylinders which extend parallel with the spindle and in which the pistons are inserted.

The connecting rods are connected to the wobble plate through ball joints to allow the precession of the connecting rods when the pistons are reciprocatingly moved. Wobble plate compressor has a number of significant characterisics: Firstly, it is easy to install on the engine and transmit power. Then, the cylinders center around the spindle, thus making the configutation more closer and realise smaller structure and lighter weight accordingly.Multi-cylinder operation to achieve dynamic balancing performance, smoothly running, sound emission, modestly variable drive torque, the well-developed design and manufacure method, along with well-created structure.
