預(yù)緊力的大小，除了受限于螺釘材料的強(qiáng)度外，還受限于被聯(lián)接件的材料強(qiáng)度。當(dāng)內(nèi)外螺紋的材料相同時，武威工業(yè)螺栓，只校核外螺紋強(qiáng)度即可。對于旋合長度較短、非標(biāo)準(zhǔn)螺紋零件構(gòu)成的聯(lián)接、內(nèi)外螺紋材料的強(qiáng)度相差較大的受軸向載荷的螺紋聯(lián)接，還應(yīng)校核螺紋牙的強(qiáng)度。

(4)對于承受動荷載或重要部位的螺栓連接，需按照設(shè)計要求放置彈簧墊圈，彈簧墊圈應(yīng)設(shè)置在螺母一側(cè)。 </p> <p> <br /> </p> <p> (5)對于工字鋼、槽鋼類型鋼應(yīng)盡可能使用斜墊圈，使得螺母和螺栓頭部的支承面垂直于螺桿。 </p> <p> <br /> </p> <p>
