一般來說(shuo)骨架油封(feng)(feng)經常用到(dao)的材質丁腈橡(xiang)膠(jiao)、氟橡(xiang)膠(jiao)、硅橡(xiang)膠(jiao)，聚(ju)四氟乙烯因為有良好的自潤滑性好尤其加入青銅后(hou)效果更佳，都用于制(zhi)作擋圈(quan)、格萊圈(quan)、斯特封(feng)(feng)等(deng)。TA ：雙唇(chun)， 有安裝彈簧， 雙鐵(tie)殼(ke) (外殼(ke)鐵(tie)殼(ke)包內殼(ke))；重慶丁晴橡(xiang)膠(jiao)油封(feng)(feng)定(ding)制(zhi)

骨架油(you)(you)封(feng)(feng)(feng)(feng)(feng)的(de)選擇方(fang)式(shi)：①單(dan)唇(chun)(chun)口(kou)(kou)油(you)(you)封(feng)(feng)(feng)(feng)(feng)主要(yao)用(yong)于密封(feng)(feng)(feng)(feng)(feng)速(su)度(du)(du)低、粘度(du)(du)大(da)(da)(如大(da)(da)黃油(you)(you))的(de)介質。②單(dan)唇(chun)(chun)口(kou)(kou)裝(zhuang)彈(dan)簧油(you)(you)封(feng)(feng)(feng)(feng)(feng)用(yong)于密封(feng)(feng)(feng)(feng)(feng)速(su)度(du)(du)高、粘度(du)(du)小的(de)介質。③雙(shuang)唇(chun)(chun)口(kou)(kou)油(you)(you)密唇(chun)(chun)口(kou)(kou)呈相反方(fang)向(xiang)(xiang)，一唇(chun)(chun)口(kou)(kou)裝(zhuang)彈(dan)簧，另(ling)一唇(chun)(chun)口(kou)(kou)不(bu)裝(zhuang)彈(dan)簧。裝(zhuang)彈(dan)簧唇(chun)(chun)口(kou)(kou)密封(feng)(feng)(feng)(feng)(feng)潤(run)(run)(run)滑(hua)劑，另(ling)一唇(chun)(chun)口(kou)(kou)密封(feng)(feng)(feng)(feng)(feng)粉塵、灰塵等異(yi)物。④雙(shuang)唇(chun)(chun)口(kou)(kou)油(you)(you)封(feng)(feng)(feng)(feng)(feng)唇(chun)(chun)口(kou)(kou)呈相反方(fang)向(xiang)(xiang)，兩唇(chun)(chun)口(kou)(kou)均裝(zhuang)有彈(dan)簧。一唇(chun)(chun)口(kou)(kou)密封(feng)(feng)(feng)(feng)(feng)潤(run)(run)(run)滑(hua)劑，另(ling)一唇(chun)(chun)口(kou)(kou)密封(feng)(feng)(feng)(feng)(feng)流(liu)體。⑤開(kai)口(kou)(kou)油(you)(you)封(feng)(feng)(feng)(feng)(feng)主要(yao)用(yong)在飛濺潤(run)(run)(run)滑(hua)處。⑥外向(xiang)(xiang)油(you)(you)封(feng)(feng)(feng)(feng)(feng)用(yong)于軸靜止而孔回(hui)轉(zhuan)的(de)地方(fang)。⑦流(liu)體動力密封(feng)(feng)(feng)(feng)(feng)用(yong)在凹槽、凸緣(yuan)等處，它將油(you)(you)擠到密封(feng)(feng)(feng)(feng)(feng)內側(ce)。新疆耐(nai)腐蝕(shi)油(you)(you)封(feng)(feng)(feng)(feng)(feng)哪(na)里買丁晴橡膠耐(nai)礦物油(you)(you)，耐(nai)磨性好(hao)，在油(you)(you)封(feng)(feng)(feng)(feng)(feng)中使用(yong)得很(hen)多。

軸的設計：

1、表(biao)面粗糙(cao)度(du)，由于軸(zhou)的(de)速度(du)與油(you)量不同，一般軸(zhou)的(de)粗糙(cao)度(du)過(guo)大(da)或過(guo)小，都會影響到油(you)封的(de)泄(xie)漏與磨損。軸(zhou)的(de)表(biao)面粗糙(cao)度(du)容許范圍為Rz1.0～5.0μm；Ra0.2～0.8μm。對旋轉軸(zhou)用油(you)封取2.5～1.6μmRz。

2、硬度(du)，旋轉軸的表面硬度(du)一般取≥35HRC。當(dang)介質較臟(zang)，有來(lai)自外(wai)界的污(wu)染雜質，或(huo)軸表速度(du)>12m/s時，軸表面硬度(du)應(ying)為(wei)55HRC以(yi)上，軸表面淬火層深度(du)>0.2mm。

3、軸的倒角(jiao)，推薦(jian)值(zhi)15°~30°，以能讓油封(feng)確實裝入，不損傷(shang)油封(feng)唇緣(yuan)為原則(ze)。

4、軸(zhou)(zhou)的(de)(de)加(jia)(jia)(jia)(jia)工(gong)，正確的(de)(de)軸(zhou)(zhou)加(jia)(jia)(jia)(jia)工(gong)是保(bao)證密封系(xi)統正常(chang)工(gong)作的(de)(de)決定性因素，適(shi)(shi)宜(yi)的(de)(de)油封軸(zhou)(zhou)加(jia)(jia)(jia)(jia)工(gong)方法是橫向(xiang)(xiang)給進精(jing)研磨(mo)，金(jin)剛(gang)(gang)砂紙(zhi)磨(mo)光(guang)(guang)。不適(shi)(shi)宜(yi)的(de)(de)加(jia)(jia)(jia)(jia)工(gong)方法是在車床上精(jing)加(jia)(jia)(jia)(jia)工(gong)，超精(jing)加(jia)(jia)(jia)(jia)工(gong)，滾光(guang)(guang)加(jia)(jia)(jia)(jia)工(gong)，金(jin)剛(gang)(gang)砂紙(zhi)磨(mo)光(guang)(guang)（砂紙(zhi)在軸(zhou)(zhou)向(xiang)(xiang)移(yi)動(dong)磨(mo)光(guang)(guang)）。

5、軸的(de)材料，主(zhu)要是普通(tong)碳素結構鋼，如C35和C45，另外(wai)還有鑄(zhu)鐵(tie)，陶瓷類，樹脂塑料，但(dan)后(hou)三(san)種材料的(de)軸對油封(feng)的(de)密(mi)封(feng)都有缺陷(xian)。
