一般式氣缸體。這種氣缸體的特點是油底殼安裝平面和曲軸旋轉(zhuǎn)中心在同一高度。其優(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。這種氣缸體的特點是油底殼安裝平面低于曲軸的旋轉(zhuǎn)中心。其優(yōu)點是強度和剛度較好，能承受較大的機械負荷，密封簡單可靠，維修方便； (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">氣缸體的結(jié)構(gòu)：1）缸筒。缸筒的內(nèi)徑大小標志了氣缸體輸出力的大小。活塞要在缸筒內(nèi)做平穩(wěn)的往復(fù)滑動，缸筒內(nèi)表面的表面粗糙度應(yīng)達到Ra0.8μm。氣缸體活塞上采用組合密封圈實現(xiàn)雙向密封，活塞與活塞桿用壓鉚鏈接，不用螺母。2）活塞桿?；钊麠U是氣缸體中比較重要的受力零件。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。3）密封圈?；剞D(zhuǎn)或往復(fù)運動處的部件密封稱為動密封，靜止件部分的密封稱為靜密封。較于活塞式氣缸體，薄膜式氣缸體的結(jié)構(gòu)緊湊簡單、成本低、壽命長、泄露小、效率高。</p><div

style="text-indent:25px">修復(fù)氣缸體、氣缸體蓋裂紋的方法：樅絲法：這種方法常用于修復(fù)單裂紋。其方法是:①用φ35mm的鉆頭先在裂紋的兩端鉆出止裂孔1和2，然后每隔2-4mm鉆出孔眼3、4;②在鉆好的孔眼中攻絲;③將紫銅棒螺釘旋入孔中，旋入的長度與氣缸體壁厚度相同，然后將紫銅棒截斷，其斷面高出氣缸體2mm;④用同樣的方法，按鉆孔的先后順序鉆出一系列的孔眼，攻絲并旋入紫銅棒螺釘。在整個裂縫上形成一條螺釘鏈;⑤用小手錘輕輕敲鉚紫銅螺釘?shù)牧舫霾糠?，使其鉚平并相互咬緊;⑥用水壓法檢查裂紋處是否漏水。如有輕微漏水.可繼續(xù)用手錘輕鉚滲漏處的紫銅螺釘。氣缸體和氣缸蓋的密封將使壓力達到理想效果。鎮(zhèn)江氣缸體加工工藝</p><p
