墊(dian)圈(quan)與(yu)密(mi)封(feng)圈(quan)的區別：
1、墊(dian)圈(quan)指(zhi)墊(dian)在被(bei)連接(jie)件(jian)與(yu)螺(luo)母之間(jian)的零件(jian)；密(mi)封(feng)圈(quan)，是由壹(yi)個(ge)或(huo)幾(ji)個零件(jian)組(zu)成的環(huan)形罩，固定(ding)在軸(zhou)承(cheng)的壹(yi)個(ge)套(tao)圈(quan)或(huo)墊(dian)圈(quan)上(shang)並(bing)與另壹(yi)套(tao)圈(quan)或(huo)墊(dian)圈(quan)接(jie)觸或形成窄的迷(mi)宮(gong)間(jian)隙(xi)壹(yi)般為(wei)扁(bian)平形的金屬環(huan)。
2、墊(dian)圈(quan)用來(lai)保(bao)護(hu)被連(lian)接(jie)件(jian)的表面(mian)不(bu)受(shou)螺(luo)母擦傷(shang)，分(fen)散螺(luo)母對被(bei)連(lian)接(jie)件(jian)的壓力。密封(feng)圈(quan)防(fang)止潤(run)滑(hua)油漏(lou)出及(ji)外(wai)物(wu)侵入(ru)。
墊(dian)圈(quan)分(fen)為(wei)：平墊(dian)圈(quan)-C級(ji)、大墊(dian)圈(quan)-A和(he)C級(ji)、特(te)大墊(dian)圈(quan)-C級(ji)、小墊(dian)圈(quan)-A級(ji)、平(ping)墊(dian)圈(quan)-A級(ji)、平(ping)墊(dian)圈(quan)-倒(dao)角(jiao)型(xing)-A級(ji)、鋼(gang)結構用高(gao)強度(du)墊(dian)圈(quan)、球面(mian)墊(dian)圈(quan)、錐(zhui)面(mian)墊(dian)圈(quan)、工(gong)字鋼(gang)用方(fang)斜(xie)墊(dian)圈(quan)、槽(cao)鋼(gang)用方(fang)斜(xie)墊(dian)圈(quan)、標準型(xing)彈(dan)簧(huang)墊(dian)圈(quan)、輕(qing)型(xing)彈(dan)簧(huang)墊(dian)圈(quan)、重(zhong)型(xing)彈(dan)簧(huang)墊(dian)圈(quan)、內(nei)齒鎖(suo)緊(jin)墊(dian)圈(quan)、內(nei)鋸齒鎖(suo)緊(jin)墊(dian)圈(quan)、外(wai)齒鎖(suo)緊(jin)墊(dian)圈(quan)、外(wai)鋸齒鎖(suo)緊(jin)墊(dian)圈(quan)、單(dan)耳(er)止動(dong)墊(dian)圈(quan)、雙(shuang)耳(er)止動(dong)墊(dian)圈(quan)、外(wai)舌(she)止動(dong)墊(dian)圈(quan)、圓螺(luo)母用止動(dong)墊(dian)圈(quan)。
