style="text-indent:25px">氣缸體如何分類，各有什么構(gòu)造特點：（1）一般式氣缸體其特點是油底殼安裝平面和曲軸旋轉(zhuǎn)中心在同一高度。這種氣缸體的優(yōu)點是機體高度小，重量輕，結(jié)構(gòu)緊湊，便于加工，曲軸拆裝方便；（2）龍門式氣缸體其特點是油底殼安裝平面低于曲軸的旋轉(zhuǎn)中心。它的優(yōu)點是強度和剛度都好，能承受較大的機械負荷。（3）隧道式氣缸體這種形式的氣缸體曲軸的主軸承孔為整體式，采用滾動軸承，主軸承孔較大，曲軸從氣缸體后部裝入。其優(yōu)點是結(jié)構(gòu)緊湊、剛度和強度好。</p><p style="text-indent:25px">氣缸體結(jié)構(gòu)：氣缸體是由缸筒、端蓋、活塞、活塞桿和密封件等組成，端蓋端蓋上設(shè)有進排氣通口，有的還在端蓋內(nèi)設(shè)有緩沖機構(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載，減小活塞桿伸出時的下彎量，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，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。氣缸體比較大的不同就是重量，鋁合金發(fā)動機比鑄鐵發(fā)動機可以輕一半的重量。</p><div
