氣缸原理：1）缸筒 缸筒的內(nèi)徑大小代表了氣缸輸出力的大小,。活塞要在缸筒內(nèi)做平穩(wěn)的往復(fù)滑動(dòng),，缸筒內(nèi)表面的表面粗糙度應(yīng)達(dá)到Ra0.8um,。對(duì)鋼管缸筒，內(nèi)表面還應(yīng)鍍硬鉻,，以減小摩擦阻力和磨損,，并能防止銹蝕。缸筒材質(zhì)除使用高碳鋼管外,，還是用高強(qiáng)度鋁合金和黃銅,。小型氣缸有使用不銹鋼管的。帶磁性開關(guān)的氣缸或在耐腐蝕環(huán)境中使用的氣缸,，缸筒應(yīng)使用不銹鋼,、鋁合金或黃銅等材質(zhì)。
　　氣缸活塞上采用組合密封圈實(shí)現(xiàn)雙向密封,，活塞與活塞桿用壓鉚鏈接,，不用螺母。
　2）端蓋 端蓋上設(shè)有進(jìn)排氣通口,，有的還在端蓋內(nèi)設(shè)有緩沖機(jī)構(gòu),。桿側(cè)端蓋上設(shè)有密封圈和防塵圈，以防止從活塞桿處向外漏氣和防止外部灰塵混入缸內(nèi),。桿側(cè)端蓋上設(shè)有導(dǎo)向套,，以提高氣缸的導(dǎo)向精度，承受活塞桿上少量的橫向負(fù)載,，減小活塞桿伸出時(shí)的下彎量,，延長氣缸使用壽命。導(dǎo)向套通常使用燒結(jié)含油合金,、前傾銅鑄件,。端蓋過去常用可鍛鑄鐵，現(xiàn)在為減輕重量并防銹,，常使用鋁合金壓鑄,，微型缸有使用黃銅材料的。
　3）活塞 活塞是氣缸中的受壓力零件,。為防止活塞左右兩腔相互竄氣,，設(shè)有活塞密封圈?；钊系哪湍キh(huán)可提高氣缸的導(dǎo)向性,，減少活塞密封圈的磨耗,，減少摩擦阻力。耐磨環(huán)長使用聚氨酯,、聚四氟乙烯,、夾布合成樹脂等材料?；钊膶挾扔擅芊馊Τ叽绾捅匾幕瑒?dòng)部分長度來決定,。滑動(dòng)部分太短,，易引起早期磨損和卡死,。活塞的材質(zhì)常用鋁合金和鑄鐵,，小型缸的活塞有黃銅制成的,。
　4）活塞桿 活塞桿是氣缸中zui重要的受力零件。通常使用高碳鋼,，表面經(jīng)鍍硬鉻處理,，或使用不銹鋼，以防腐蝕,，并提高密封圈的耐磨性,。
　5）密封圈 回轉(zhuǎn)或往復(fù)運(yùn)動(dòng)處的部件密封稱為動(dòng)密封，靜止件部分的密封稱為靜密封,。
缸筒與端蓋的連接方法主要有以下幾種：
　　整體型、鉚接型,、螺紋聯(lián)接型,、法蘭型、拉桿型,。
　6）氣缸工作時(shí)要靠壓縮空氣中的油霧對(duì)活塞進(jìn)行潤滑,。也有小部分免潤滑氣                                       費(fèi)斯托部分產(chǎn)品型號(hào)：LFMBA-1/2-D-MAXI-A
