螺栓與扳手大小怎么換算
一般(ban)是(shi)(shi)(shi)螺(luo)栓的(de)(de)(de)直(zhi)徑乘以1.5倍就(jiu)是(shi)(shi)(shi)呆口(kou)、梅(mei)花(hua)的(de)(de)(de)尺(chi)(chi)(chi)寸。內(nei)六角(jiao)扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou)一般(ban)是(shi)(shi)(shi)螺(luo)栓的(de)(de)(de)直(zhi)徑減去(qu)2。所有的(de)(de)(de)扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou),包(bao)括開(kai)口(kou)扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou)、內(nei)六角(jiao)扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou)、梅(mei)花(hua)扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou)、套筒扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou)等,其(qi)尺(chi)(chi)(chi)寸都是(shi)(shi)(shi)指螺(luo)栓頭部(bu)對(dui)(dui)邊(bian)的(de)(de)(de)寬度(du)尺(chi)(chi)(chi)寸,而螺(luo)栓的(de)(de)(de)規格是(shi)(shi)(shi)指螺(luo)紋的(de)(de)(de)公稱直(zhi)徑。螺(luo)栓和(he)扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou)的(de)(de)(de)標(biao)準有很多,換(huan)算方法也不同,例如(ru),M10的(de)(de)(de)外六角(jiao)螺(luo)栓,其(qi)對(dui)(dui)邊(bian)寬度(du)為(wei)16mm,就(jiu)選用16的(de)(de)(de)開(kai)口(kou)扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou)或梅(mei)花(hua)扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou)。又如(ru)GB/70-85內(nei)六角(jiao)螺(luo)栓,M10的(de)(de)(de)內(nei)六角(jiao)螺(luo)栓的(de)(de)(de)對(dui)(dui)邊(bian)尺(chi)(chi)(chi)寸為(wei)8mm,則選用8mm的(de)(de)(de)內(nei)六角(jiao)扳(ban)(ban)(ban)(ban)手(shou)(shou)(shou)(shou)(shou)。
1、計算標(biao)準(zhun)螺栓(shuan)螺母尺(chi)(chi)寸(扳(ban)手尺(chi)(chi)寸)的經驗公(gong)式(采用(yong)分數形式):
標準螺(luo)(luo)栓螺(luo)(luo)母尺寸(扳手尺寸)=(螺(luo)(luo)栓螺(luo)(luo)紋尺寸分子(zi)×3)÷(螺(luo)(luo)栓螺(luo)(luo)紋尺寸分子(zi)×2)
例(li)如:1/2英(ying)寸(cun)螺(luo)紋的(de)標準螺(luo)栓對應的(de)扳手(shou)尺寸(cun)=(1×3)÷(2×2)英(ying)寸(cun)=3/4英(ying)寸(cun)
2、計算加重(zhong)螺栓螺母尺寸(cun)(cun)(扳手尺寸(cun)(cun))的經(jing)驗(yan)公式(采(cai)用分數形式):
加(jia)重螺栓(shuan)螺母(mu)尺寸(cun)(扳手尺寸(cun))=標準螺栓(shuan)螺母(mu)尺寸(cun)1/8。
例如:1/2英(ying)寸(cun)螺紋的加重(zhong)螺栓對應的扳手(shou)尺寸(cun)=(1×3)÷(2×2)英(ying)寸(cun)1/8=7/8英(ying)寸(cun)。
