CKD氣缸@日本CKD/喜開理@ckd氣動(dòng)

                        　　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)。

                        喜開理CKD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(zhǎng)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。活塞上的耐磨環(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(zhǎng)使用聚氨酯、聚四氟乙烯、夾布合成樹脂等材料。活塞的寬度由密封圈尺寸和必要的滑動(dòng)部分長(zhǎng)度來(lái)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）喜開理CKD標(biāo)準(zhǔn)氣缸活塞桿

                        　　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）喜開理CKD標(biāo)準(zhǔn)氣缸工作時(shí)要靠壓縮空氣中的油霧對(duì)活塞進(jìn)行潤(rùn)滑。也有小部分免潤(rùn)滑氣缸。
