style="text-indent:25px">螺栓：由頭部和螺桿（帶有外螺紋的圓柱體）兩部分構(gòu)成的一類緊固件，需與螺母配合，用于緊固連接兩個帶有通孔的零件。螺釘：也是由頭部和螺桿兩部分構(gòu)成的一類緊固件，按用途可以分為三類———機(jī)器螺釘、緊定螺釘和特殊用途螺釘。機(jī)器螺釘主要用于一個帶有內(nèi)螺紋孔的零件，與一個帶有通孔的零件之間的緊固連接，不銹鋼螺栓，不需要螺母配合（這種連接形式稱為螺釘連接，也屬可拆卸連接；也可以與螺母配合，用于兩個帶有通孔的零件之間的緊固連接，不銹鋼螺栓。緊定螺釘主要用于固定兩個零件之間的相對位置，不銹鋼螺栓。特殊用途螺釘有吊環(huán)螺釘，供吊裝零件用.螺栓：機(jī)械零件，配用螺母的圓柱形帶螺紋的緊固件。不銹鋼螺栓</p><div

style="text-indent:25px">構(gòu)件間的夾緊力是靠對螺栓施加預(yù)拉力來實(shí)現(xiàn)的，所以螺栓必須采用**度鋼制造，這也就是稱為**度螺栓連接的原因。**度螺栓連接中，摩擦系數(shù)的大小對承載力的影響很大。試驗(yàn)表明，摩擦系數(shù)主要受接觸面的形式和構(gòu)件的材質(zhì)影響。為了增大接觸面的摩擦系數(shù)，施工時常采用應(yīng)噴砂、用鋼絲刷清理等方法對連接范圍內(nèi)構(gòu)件接觸面進(jìn)行處理。**度螺栓實(shí)際上有摩擦型和承壓型兩種。摩擦型**度螺栓承受剪力的準(zhǔn)則是設(shè)計(jì)荷載引起的剪力不超過摩擦力。承壓型**度螺栓則是以桿身不被剪壞或板件不被壓壞為設(shè)計(jì)準(zhǔn)則。不銹鋼螺栓螺栓材質(zhì)為低碳合金鋼或中碳鋼。</p><div

style="text-indent:25px">在抗剪設(shè)計(jì)時，**螺的栓承壓型連接中允許外剪力超過較大摩擦力，這時被連接板件之間發(fā)生相對滑移變形，直到螺栓桿與孔壁接觸，此后連接就靠螺栓桿身剪切和孔壁承壓以及板件接觸面間的摩擦力共同傳力，之后以桿身剪切或孔壁承壓破壞作為連接受剪的極限狀態(tài)?？傊Σ列?*螺栓和承壓型**螺栓實(shí)際上是同一種螺栓，只不過是設(shè)計(jì)是否考慮滑移。摩擦型**螺栓一定不能滑動，螺栓不承受剪力，一旦滑移，設(shè)計(jì)就認(rèn)為達(dá)到破壞狀態(tài)，在技術(shù)上比較成熟；承壓型**螺栓可以滑動，螺栓也承受剪力，之后破壞相當(dāng)于普通螺栓破壞（螺栓剪壞或鋼板壓壞）。</p><p style="text-indent:25px">法蘭螺栓(GB5787/DIN6921)的外表看上去和一般的普通六角頭螺栓的區(qū)別并不是很大，但是還是有著一定的區(qū)別的，例如六角法蘭面螺栓的頭部就是由六角頭和法蘭面兩部分組成的，這也是和普通六角頭螺栓的根本的區(qū)別。因?yàn)樗倪@種結(jié)構(gòu)，所以其“支撐面積與應(yīng)力面積字比值”要比普通六角頭螺栓更大一些，也是因此六角法蘭面螺栓所能夠承受的預(yù)緊力也更好，也就意味著它具有更強(qiáng)的防松性能，因此其被普遍使用于汽車發(fā)動機(jī)、重型機(jī)械等產(chǎn)品上，并具有很好地使用效果。沉頭螺絲又被稱為平機(jī)螺絲。</p><div

style="text-indent:25px">在檢測螺栓硬度時，沒有熱處理的螺栓，只需要做表面硬度在合格范圍內(nèi)就行了。如果是熱處理螺栓就要在末部切一個直徑的面上打硬度，硬度測試在面上的1/2R處。它有一個表面，一個芯部，表面是指在去除表面浮銹等之后用維氏或表面洛氏打硬度，芯部要在去除末部1/2直徑長度后在表面與芯部1/2R的地方打硬度，兩個硬度之差不能超過30個HV，表面高出30HV說明表面滲碳了，是不能允許的.如果表面低了30HV以上說明表面脫碳了，也是不能允許的。固定地腳螺栓又稱為短地腳螺栓。不銹鋼螺栓</p><p style="text-indent:25px">螺栓：M medium中等的中號螺栓。不銹鋼螺栓</p><p style="text-indent:25px">螺栓：螺桿未達(dá)到預(yù)調(diào)溫度時，切勿啟動機(jī)器。防止金屬碎片及雜物落入料斗，若加工回收料，便需加上磁性料斗以防止鐵屑等進(jìn)入料筒。使用防涎時要確定料筒內(nèi)塑料完全熔融，以免螺桿后退時損壞傳動系統(tǒng)零件。使用新塑料時，應(yīng)把螺桿的余料清洗干凈。當(dāng)熔融塑料溫度正常但又不斷發(fā)現(xiàn)熔融塑料出現(xiàn)黑點(diǎn)或變色時，應(yīng)檢查膠螺.在加工時，盡量使物料塑化均勻，不要讓金屬異物混入料中，減少螺桿轉(zhuǎn)動扭矩力按連接的受力方式分：分普通的和有鉸制孔用的。按頭部形狀分：有六角頭的，圓頭的，方形頭的，沉頭的等等。其中六角頭是較常用的。一般沉頭用在要求連接的地方。不銹鋼螺栓</p><p
