style="text-indent:25px">U型掛環(huán)外形與卸扣很相似，但二者作用不同，卸扣是一種起吊用的鎖具，表面處理多是電鍍鋅，而U型掛環(huán)則是用于供電線路上的熱鍍鋅電力金具。這一點(diǎn)，在購買時(shí)要注意的。U形掛環(huán)根據(jù)型式尺寸不同可分為U型、UL型U--U形，L--延長(zhǎng)，數(shù)字--標(biāo)稱破壞荷重標(biāo)記。技術(shù)要求：U形掛環(huán)一般技術(shù)條件應(yīng)符合GB2314—85《電力金具通用技術(shù)條件》的規(guī)定。U形掛環(huán)的聯(lián)結(jié)尺寸應(yīng)符合GB2315—85《電力金具標(biāo)稱破壞荷重系列及零件聯(lián)結(jié)尺寸》的規(guī)定。U形掛環(huán)的設(shè)計(jì)、制造、試驗(yàn)、驗(yàn)收、及標(biāo)志與包裝等要求應(yīng)符合DL/T759-2009電力行業(yè)標(biāo)準(zhǔn)《連接金具》的規(guī)定。</p><p style="text-indent:25px">U型環(huán)的強(qiáng)度計(jì)算：U型環(huán)的連接是一種簡(jiǎn)單的連接方式。在U型環(huán)與孔、雙板與單板之間總有一些間隙，因此U型環(huán)要承受彎矩(與U型環(huán)受剪切相比，彎矩居主要地位)故必須計(jì)算器抗彎強(qiáng)度。U型環(huán)的剪應(yīng)力為:Tp-U型環(huán)的許用剪應(yīng)力，U型環(huán)的常用材料鋼Q235、Q245?？扇p=80N/mm2；d-U型環(huán)的直徑。在外荷載P的作用下，并假定荷載通過孔板傳到U型環(huán)上，沿零件的寬度均勻分布，則U型環(huán)上所產(chǎn)生的彎矩為:M=2(24)兩支之間的距離；經(jīng)熱鍍鋅后的鍛制件、沖壓件的外觀質(zhì)量:沖裁件的剪切斷面斜度偏差小于板厚的十分之一。硅橡膠
