Product Description

螺栓,機(jī)械零件,配用螺母的圓柱形帶螺紋的緊固件。螺栓:由頭部和螺桿(帶有外螺紋的圓柱體)兩部分組成的一類緊固件,需與螺母配合,用于緊固連接兩個(gè)帶有通孔的零件。這種連接形式稱螺栓連接。如把螺母從螺栓上旋下,又可以使這兩個(gè)零件分開,故螺栓連接是屬于可拆卸連接。 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T形的,六角頭的,圓頭的,方形頭的,沉頭的等等。其中六角頭是常用的。一般沉頭用在要求連接的地方。應(yīng)用非常廣泛。 ? ?螺栓有很多叫法,每個(gè)人的叫法可能都不同,有人叫成螺釘,有人叫成螺栓釘,有人叫成標(biāo)準(zhǔn)件,有人叫成緊固件。雖然有這么多叫法,但意思都是一樣的,都是螺栓。螺栓是緊固件的通用說法。螺栓的原理是利用物體的斜面圓形旋轉(zhuǎn)和摩擦力的物理學(xué)和數(shù)學(xué)原理,循序漸進(jìn)地緊固器物機(jī)件的工具。?

螺栓在日常生活當(dāng)中和工業(yè)生產(chǎn)制造當(dāng)中,是少不了的,螺栓也被稱為工業(yè)之米??梢娐菟ǖ倪\(yùn)用之廣泛。螺栓的運(yùn)用范圍有:電子產(chǎn)品,機(jī)械產(chǎn)品,數(shù)碼產(chǎn)品,電力設(shè)備,機(jī)電機(jī)械產(chǎn)品。船舶,車輛,水利工程,甚至化學(xué)實(shí)驗(yàn)上也有用到螺栓。反正是超多地方都有用到螺栓的。特如數(shù)碼產(chǎn)品上面用到的精密螺栓。DVD,照相機(jī)、眼鏡、鐘表、電子等使用的微型螺栓;電視、電氣制品、樂器、家具等之一般螺栓;至于工程、建筑、橋梁則使用大型螺栓、螺帽;交通器具、飛機(jī)、電車、汽車等則為大小螺栓并用。螺栓在工業(yè)上負(fù)有重要任務(wù),只要地球上存在著工業(yè),則螺栓之功能永遠(yuǎn)重要。
