1、端(duan)面(mian)密封副(靜、動環)

端面(mian)密封副的作用是使(shi)密封面(mian)緊密貼合(he), 防(fang)止介質泄漏。 它要(yao)求靜、動(dong)(dong)(dong)(dong)環(huan)具有(you)良好的耐(nai)磨(mo)性(xing), 動(dong)(dong)(dong)(dong)環(huan)可以軸向(xiang)靈活地移動(dong)(dong)(dong)(dong),自動(dong)(dong)(dong)(dong)補償密封面(mian)磨(mo)損, 使(shi)之與靜環(huan)良好地貼合(he); 靜環(huan)具有(you)浮動(dong)(dong)(dong)(dong)性(xing), 起緩沖作用。

2、彈性元件(jian)(彈簧)

它主要起(qi)預(yu)緊、補償和(he)(he)緩沖的作(zuo)用(yong), 要求始終保持足(zu)夠的彈性來克服輔助密封和(he)(he)傳動(dong)件的摩擦(ca)和(he)(he)動(dong)環(huan)等(deng)的慣(guan)性, 保證端面密封副良好的貼(tie)合和(he)(he)動(dong)環(huan)的追(zhui)隨性。

3、 輔助密封(O形(xing)圈)

它主要起靜(jing)(jing)環(huan)(huan)(huan)和(he)動(dong)(dong)(dong)環(huan)(huan)(huan)的密(mi)封(feng)(feng)(feng)(feng)作用(yong)(yong), 同時也起到浮(fu)(fu)(fu)動(dong)(dong)(dong)和(he)緩(huan)沖作用(yong)(yong)。 要求靜(jing)(jing)環(huan)(huan)(huan)的密(mi)封(feng)(feng)(feng)(feng)元件能保(bao)證靜(jing)(jing)環(huan)(huan)(huan)與(yu)壓蓋之(zhi)間的密(mi)封(feng)(feng)(feng)(feng)性(xing)和(he)靜(jing)(jing)環(huan)(huan)(huan)有一定的浮(fu)(fu)(fu)動(dong)(dong)(dong)性(xing), 動(dong)(dong)(dong)環(huan)(huan)(huan)的密(mi)封(feng)(feng)(feng)(feng)元件能保(bao)證動(dong)(dong)(dong)環(huan)(huan)(huan)與(yu)軸或軸套之(zhi)間的密(mi)封(feng)(feng)(feng)(feng)性(xing)和(he)動(dong)(dong)(dong)環(huan)(huan)(huan)的浮(fu)(fu)(fu)動(dong)(dong)(dong)性(xing)。

4、傳動件(傳動銷)

它起到將(jiang)軸的(de)轉矩傳給動環的(de)作(zuo)用。

5、緊固件(緊固螺釘、壓蓋、軸套(tao))

它起到靜、動環的(de)(de)定(ding)(ding)位、緊(jin)固的(de)(de)作用(yong)。 要求軸向定(ding)(ding)位正(zheng)確(que), 保(bao)證一定(ding)(ding)的(de)(de)彈簧壓縮量(liang), 使密封副密封面處于正(zheng)確(que)的(de)(de)位置并保(bao)持(chi)良好的(de)(de)貼合(he)。

6、防轉件(jian)(防轉銷)

它起到防止(zhi)靜(jing)環轉動和脫出的(de)作(zuo)用。要求有足夠(gou)的(de)長度(du), 防止(zhi)靜(jing)環在負壓下脫出, 并(bing)要求正(zheng)確定位, 防止(zhi)靜(jing)環隨動環旋轉。
