style="text-indent:25px">氣缸體上部是并列的氣缸體筒，目前多鑲有氣缸套。氣缸體的下部是曲軸箱，用來(lái)安裝曲軸，其外部還可安裝發(fā)電機(jī)、發(fā)動(dòng)機(jī)支架等各種附件。氣缸體大多用鑄鐵或鋁合金鑄造而成，鋁合金缸體成本較高，但重量輕、冷卻性能好，得到越來(lái)越普遍的應(yīng)用。干式氣缸套的特點(diǎn)是氣缸套裝入氣缸體后，其外壁不直接與冷卻水接觸，而和氣缸體的壁面直接接觸，壁厚較薄，一般為1～3mm。它具有整體式氣缸體的優(yōu)點(diǎn)，強(qiáng)度和剛度都較好，但加工比較復(fù)雜，內(nèi)、外表面都需要進(jìn)行精加工，拆裝不方便，散熱不良。靖江標(biāo)準(zhǔn)復(fù)動(dòng)型氣缸氣缸體的活塞是氣缸體中的受壓力零件。</p><div

style="text-indent:25px">氣缸體的工作條件十分惡劣。它要承受燃燒過(guò)程中壓力和溫度的急劇變化以及活塞運(yùn)動(dòng)的強(qiáng)烈摩擦。因此，它應(yīng)具有以下性能：①有足夠的強(qiáng)度和剛度，變形小，保證各運(yùn)動(dòng)零件位置正確，運(yùn)轉(zhuǎn)正常，振動(dòng)噪聲小。②有良好的冷卻性能，在缸筒的四周有冷卻水套，以便讓冷卻水帶走熱量。③耐磨，以保證氣缸體有足夠的使用壽命。氣缸體比較大的不同就是重量，鋁合金發(fā)動(dòng)機(jī)比鑄鐵發(fā)動(dòng)機(jī)可以輕一半的重量。本來(lái)轎車的總重量就不高，發(fā)動(dòng)機(jī)所占的比例可是不能忽略，重量減輕的比較直接效果便是油耗方面表現(xiàn)的增強(qiáng)。而發(fā)動(dòng)機(jī)的重量也直接影響車輛的行駛性能，由于一般轎車多為前輪驅(qū)動(dòng)。</p><p

m的低碳鋼板切成補(bǔ)板，補(bǔ)板比裂紋周圍大20-30mm; ④沿補(bǔ)板周圍鉆孔，孔距為15~ 20mm，孔徑3-5mm; ⑤將補(bǔ)板覆蓋在裂紋上，使其與氣缸體或氣缸體蓋貼合緊密，隨后以補(bǔ)板為樣板在氣缸體或氣缸體蓋上鉆孔，并攻絲;⑥用螺釘把補(bǔ)板固定，在補(bǔ)板與氣缸體或氣缸體蓋之間，可墊上一層石棉墊，或在兩個(gè)貼面上涂上紅丹油。氣缸體的桿側(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)。義烏氣缸體的結(jié)構(gòu)形式</p><p
