為了提高緊固件的使用性能,會(huì)對(duì)其進(jìn)行熱鍍鋅工藝。熱鍍鋅屬于一種對(duì)金屬表層進(jìn)行處理的工藝技術(shù),主要是提高金屬表面的防腐蝕性的,那么這樣會(huì)具備哪些優(yōu)勢(shì)呢?可靠性好:鍍鋅層與鋼材間是冶金結(jié)合,成為鋼表面的一部份,因此鍍層的持久性較為可靠;性保護(hù):鍍件的每一部分都能鍍上鋅,即使在凹陷處、尖角及隱藏處都能受到保護(hù);處理費(fèi)用低:熱浸鍍鋅防銹的費(fèi)用要比其他漆料涂層的費(fèi)用低;省時(shí)省力:鍍鋅過(guò)程要比其他的涂層施工法更快捷,并且可避免安裝后在工地上涂刷所需的時(shí)間;持久耐用:在郊區(qū)環(huán)境下,標(biāo)準(zhǔn)的熱鍍鋅防銹厚度可保持5年以上而不必修補(bǔ);在市區(qū)或近海區(qū)域,標(biāo)準(zhǔn)的熱鍍鋅防銹層則可保持2年而不必修補(bǔ);鍍層的韌性強(qiáng):鍍鋅層形成一種特別的冶金結(jié)構(gòu),這種結(jié)構(gòu)能承受在運(yùn)送及使用時(shí)受到機(jī)械損傷。

不會(huì)發(fā)生屈服。1內(nèi)壓15MPa作用由《應(yīng)力集中系數(shù)手冊(cè)》查得筒壁開(kāi)有小孔的厚壁圓筒承受內(nèi)壓時(shí)，可得應(yīng)力集中系數(shù)A=3.34結(jié)論不會(huì)發(fā)生屈服。從以上應(yīng)力分析，可以得出以下幾點(diǎn)結(jié)論：4.1在三種給定載荷作用下，拉伸載荷作用下的應(yīng)力，安全系數(shù)。拉伸載荷下的強(qiáng)度條件是主要矛盾。2拉伸以常用旋塞閥材料4CrMnMo計(jì)算，安全系數(shù)為1.711.5，能夠滿(mǎn)足強(qiáng)度要求。3拉伸載荷下旋鈕孔口處的應(yīng)力集中較大，在應(yīng)力集中點(diǎn)都達(dá)到了材料的屈服極限，按照新的強(qiáng)度準(zhǔn)則，應(yīng)力集中點(diǎn)的值935.75MPa2MPa，滿(mǎn)足安定條件。
據(jù)統(tǒng)計(jì)，除自產(chǎn)自用外，市場(chǎng)銷(xiāo)售方面，2010年我國(guó)編碼器聯(lián)軸器總需求約為313億元人民幣，國(guó)產(chǎn)編碼器聯(lián)軸器總供給約為230億元人民幣，市場(chǎng)滿(mǎn)足率為73.5%。進(jìn)口的編碼器聯(lián)軸器中，多的是為汽車(chē)配套的各種裝飾件聯(lián)軸器、為家電配套的各種塑殼聯(lián)軸器、為通信及辦公設(shè)備配套的各種注塑聯(lián)軸器、為建材配套的擠塑編碼器聯(lián)軸器以及為電子工業(yè)配套的各種塑封聯(lián)軸器等。出口的編碼器聯(lián)軸器以中低檔產(chǎn)品居多。由于我國(guó)編碼器聯(lián)軸器價(jià)格較低，在市場(chǎng)中有較強(qiáng)的競(jìng)爭(zhēng)力，所以進(jìn)一步擴(kuò)大出口的前景很不錯(cuò)。

從1732年美國(guó)富蘭克林主張電為體學(xué)說(shuō)，到19世紀(jì)初電磁感應(yīng)現(xiàn)象的發(fā)現(xiàn)、電報(bào)的發(fā)明等，人類(lèi)經(jīng)歷了漫長(zhǎng)的對(duì)電的研究和應(yīng)用過(guò)程。也正是對(duì)電的測(cè)量與研究以及對(duì)電特性的廣泛應(yīng)用，大大推動(dòng)了工業(yè)企業(yè)的自動(dòng)化進(jìn)程，提高了工業(yè)企業(yè)的生產(chǎn)效率。所以人們習(xí)慣稱(chēng)第二工業(yè)革命為電氣時(shí)代。為紀(jì)念科學(xué)家對(duì)電及其特性的發(fā)現(xiàn)以及對(duì)電測(cè)量所做出的卓越貢獻(xiàn)，上以相關(guān)科學(xué)家的名字來(lái)定義電學(xué)的有關(guān)計(jì)量單位。如：以法國(guó)科學(xué)家?guī)靵龅拿肿鰹殡娏康挠?jì)量單位；以意大利科學(xué)家伏特的名字做為電壓的計(jì)量單位；以法國(guó)科學(xué)家安培的名字做為電流的計(jì)量單位；以英國(guó)科學(xué)家焦耳的名字做為電能的計(jì)量單位。
