擋圈一般指軸用擋圈。軸用擋圈是一種安裝于槽軸上，用作固定零部件的孔向運(yùn)動(dòng)，這類擋圈的內(nèi)徑比裝配軸徑稍小。安裝時(shí)須用卡簧鉗，將鉗嘴插入擋圈的鉗孔中，擴(kuò)張擋圈，才能放入預(yù)先加工好的軸槽上。 </p> <p> 按用途分類<br /> 1．軸用彈性擋圈<br /> a）單孔軸用擋圈<br /> b）雙孔軸用擋圈<br /> 2．反向軸用彈性擋圈<br /> 軸承擋圈的作用就是防止軸承發(fā)生不必要的軸向竄動(dòng)。 </p> <p> 材料<br /> 1）碳素彈簧鋼<br /> 2）不銹鋼<br /> 標(biāo)準(zhǔn)<br /> 1) GB 894.1<br /> 2）JIS B2804<br /> 3) DIN 471<br /> 4）ANSI<br /> 5）ISO<br />

style="text-indent:25px">墊圈的作用—紙墊：紙墊我們在生活中還是會(huì)常見到的，它的作用有兩種，第1是增加密封性，二是用來調(diào)整部件之間的間隙。墊圈的作用—平墊：平墊的作用是讓螺母的壓力可以軍屯的分布在受壓件上面，同時(shí)還起到了保護(hù)螺栓絲扣和連接體的表面。一般薄的金屬殼體固定采用金屬平墊。墊圈的作用—銅平墊：銅平墊的材質(zhì)一般是會(huì)采用紫銅材質(zhì)的，大都使用在壓力較大的部位，例如噴油嘴的墊圈。墊圈的作用—軟木墊：軟木墊具有一定的韌性，一般用于水箱、發(fā)動(dòng)機(jī)油底殼與機(jī)體之間。軟木墊質(zhì)地松軟，密封性能好，緩減部件的震動(dòng)、碰撞和磨損。弱點(diǎn)是松脆易碎。在安裝防松墊圈時(shí)無需使用扭力扳手。</p><div

style="text-indent:25px">墊圈是指墊在被連接件與螺母之間的零件。墊圈一般為扁平形的金屬環(huán)，用來保護(hù)被連接件的表面不受螺母擦傷，分散螺母對被連接件的壓力，可分為彈簧墊圈、平墊圈等。墊圈分為：平墊圈-C級、大墊圈-A和C級、特大墊圈-C級、小墊圈-A級、平墊圈-A級、平墊圈-倒角型-A級、鋼結(jié)構(gòu)用**度墊圈、球面墊圈、錐面墊圈、工字鋼用方斜墊圈、槽鋼用方斜墊圈、標(biāo)準(zhǔn)型彈簧墊圈、輕型彈簧墊圈、重型彈簧墊圈、內(nèi)齒鎖緊墊圈、內(nèi)鋸齒鎖緊墊圈、外齒鎖緊墊圈、外鋸齒鎖緊墊圈、單耳止動(dòng)墊圈。彈簧墊圈的彈簧的基本作用是再螺母擰緊之后給螺母一個(gè)力。沖壓墊片價(jià)格</p><p

對于200HV和300HV級的應(yīng)選用45、50、60、70鋼或65Mn鋼，可通過熱處理淬火回火達(dá)到200～300HV和300～400HV技術(shù)要求。<br /> 由于根據(jù)標(biāo)準(zhǔn)對于100HV
