1、端面密封(feng)副(靜、動(dong)環)

端面(mian)密封副的作(zuo)(zuo)用是使密封面(mian)緊(jin)密貼(tie)合, 防止介質泄(xie)漏。 它(ta)要(yao)求靜(jing)、動(dong)(dong)環具有良(liang)好的耐磨性, 動(dong)(dong)環可(ke)以(yi)軸向靈活(huo)地(di)移動(dong)(dong),自動(dong)(dong)補償(chang)密封面(mian)磨損, 使之與靜(jing)環良(liang)好地(di)貼(tie)合; 靜(jing)環具有浮動(dong)(dong)性, 起緩沖作(zuo)(zuo)用。

2、彈(dan)性元件(彈(dan)簧)

它主要起預緊、補償和(he)緩沖(chong)的作用(yong), 要求始終保持足夠的彈性來克(ke)服輔助密封和(he)傳動(dong)件的摩擦和(he)動(dong)環等的慣性, 保證端面(mian)密封副良好(hao)的貼合和(he)動(dong)環的追隨(sui)性。

3、 輔助密封(O形(xing)圈)

它主要(yao)起靜(jing)環(huan)(huan)(huan)和動(dong)(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)的(de)(de)密(mi)封作(zuo)用(yong), 同時也起到浮動(dong)(dong)(dong)(dong)(dong)(dong)和緩(huan)沖作(zuo)用(yong)。 要(yao)求靜(jing)環(huan)(huan)(huan)的(de)(de)密(mi)封元件能保證(zheng)靜(jing)環(huan)(huan)(huan)與(yu)壓蓋之間(jian)的(de)(de)密(mi)封性和靜(jing)環(huan)(huan)(huan)有一(yi)定(ding)的(de)(de)浮動(dong)(dong)(dong)(dong)(dong)(dong)性, 動(dong)(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)的(de)(de)密(mi)封元件能保證(zheng)動(dong)(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)與(yu)軸或軸套之間(jian)的(de)(de)密(mi)封性和動(dong)(dong)(dong)(dong)(dong)(dong)環(huan)(huan)(huan)的(de)(de)浮動(dong)(dong)(dong)(dong)(dong)(dong)性。

4、傳動(dong)件(傳動(dong)銷)

它起到將軸的轉矩傳給動環的作用。

5、緊固件(緊固螺釘、壓蓋、軸套)

它起到靜、動環的定位(wei)、緊(jin)固的作用。 要(yao)求軸(zhou)向定位(wei)正(zheng)確(que), 保證一定的彈(dan)簧(huang)壓縮量, 使密封(feng)副密封(feng)面處(chu)于正(zheng)確(que)的位(wei)置(zhi)并保持良好的貼合。

6、防轉件(防轉銷(xiao))

它起到防(fang)止(zhi)靜(jing)環(huan)轉(zhuan)動(dong)(dong)和(he)脫(tuo)出的(de)作(zuo)用。要(yao)(yao)求有(you)足(zu)夠的(de)長(chang)度, 防(fang)止(zhi)靜(jing)環(huan)在負(fu)壓下脫(tuo)出, 并要(yao)(yao)求正(zheng)確定位, 防(fang)止(zhi)靜(jing)環(huan)隨動(dong)(dong)環(huan)旋(xuan)轉(zhuan)。
