墊(dian)圈(quan)與密(mi)封(feng)圈(quan)的區(qu)別：
1、墊(dian)圈(quan)指墊(dian)在(zai)被連接件(jian)與螺(luo)母(mu)之間(jian)的零件；密封(feng)圈(quan)，是由(you)壹(yi)個或(huo)幾(ji)個(ge)零件組(zu)成(cheng)的環(huan)形(xing)罩，固(gu)定(ding)在(zai)軸承(cheng)的壹(yi)個套(tao)圈(quan)或(huo)墊(dian)圈(quan)上並與另(ling)壹(yi)套(tao)圈(quan)或(huo)墊(dian)圈(quan)接觸或(huo)形(xing)成(cheng)窄(zhai)的迷(mi)宮(gong)間(jian)隙壹(yi)般為扁(bian)平(ping)形(xing)的金屬(shu)環(huan)。
2、墊(dian)圈(quan)用來保護(hu)被連接件(jian)的表(biao)面(mian)不(bu)受螺母(mu)擦(ca)傷，分散(san)螺母(mu)對(dui)被(bei)連接件(jian)的壓力。密封圈(quan)防止(zhi)潤(run)滑油漏出(chu)及外(wai)物(wu)侵入。
墊(dian)圈(quan)分為(wei)：平墊(dian)圈(quan)-C級(ji)、大(da)墊(dian)圈(quan)-A和(he)C級(ji)、特(te)大墊(dian)圈(quan)-C級(ji)、小(xiao)墊(dian)圈(quan)-A級(ji)、平(ping)墊(dian)圈(quan)-A級(ji)、平(ping)墊(dian)圈(quan)-倒(dao)角型-A級(ji)、鋼(gang)結構(gou)用(yong)高(gao)強度墊(dian)圈(quan)、球面(mian)墊(dian)圈(quan)、錐面(mian)墊(dian)圈(quan)、工(gong)字(zi)鋼(gang)用方(fang)斜墊(dian)圈(quan)、槽(cao)鋼(gang)用方(fang)斜墊(dian)圈(quan)、標準型彈(dan)簧墊(dian)圈(quan)、輕(qing)型(xing)彈(dan)簧墊(dian)圈(quan)、重(zhong)型彈(dan)簧墊(dian)圈(quan)、內齒(chi)鎖(suo)緊(jin)墊(dian)圈(quan)、內鋸齒(chi)鎖(suo)緊(jin)墊(dian)圈(quan)、外齒(chi)鎖(suo)緊(jin)墊(dian)圈(quan)、外鋸齒(chi)鎖(suo)緊(jin)墊(dian)圈(quan)、單耳止(zhi)動墊(dian)圈(quan)、雙(shuang)耳止(zhi)動墊(dian)圈(quan)、外舌止(zhi)動墊(dian)圈(quan)、圓(yuan)螺母(mu)用(yong)止(zhi)動墊(dian)圈(quan)。
