目前市(shi)面上的(de)工業風扇電機輸(shu)(shu)出(chu)軸與(yu)輪轂(gu)的(de)連接分為(wei)兩種(zhong)，一種(zhong)是(shi)(shi)高(gao)強度的(de)螺(luo)(luo)栓(shuan)(shuan)連接，還有一種(zhong)是(shi)(shi)漲緊裝置(zhi)形成(cheng)結構性(xing)(xing)自(zi)鎖，即使在輸(shu)(shu)出(chu)軸端螺(luo)(luo)栓(shuan)(shuan)松脫的(de)情況下，仍然可(ke)以保證輪轂(gu)和輸(shu)(shu)出(chu)軸可(ke)靠(kao)的(de)緊固在一起。無論是(shi)(shi)螺(luo)(luo)栓(shuan)(shuan)連接，還是(shi)(shi)結構性(xing)(xing)自(zi)鎖與(yu)螺(luo)(luo)栓(shuan)(shuan)連接，我們可(ke)以發現共同(tong)點，都會安裝螺(luo)(luo)栓(shuan)(shuan)，所以現在就聊聊高(gao)強度螺(luo)(luo)栓(shuan)(shuan)的(de)安全(quan)方法。

      高(gao)強(qiang)度螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)的(de)(de)(de)安裝(zhuang)(zhuang)應(ying)(ying)在(zai)工(gong)業(ye)風扇(shan)結構(gou)構(gou)件(jian)(jian)中(zhong)心位置調整好(hao)后進行，其穿入方向以施工(gong)方便(bian)為準，并力求一致。高(gao)強(qiang)度螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)連接副(fu)件(jian)(jian)組裝(zhuang)(zhuang)時(shi)，螺(luo)(luo)(luo)(luo)(luo)母帶(dai)圓臺面(mian)的(de)(de)(de)一側應(ying)(ying)朝向墊圈(quan)有倒角(jiao)的(de)(de)(de)一側。對(dui)于(yu)大(da)六角(jiao)頭(tou)高(gao)強(qiang)螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)連接副(fu)件(jian)(jian)組裝(zhuang)(zhuang)時(shi)，螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)頭(tou)下墊圈(quan)有倒角(jiao)的(de)(de)(de)一側應(ying)(ying)朝向螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)頭(tou)。一個接頭(tou)上的(de)(de)(de)高(gao)強(qiang)螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)，應(ying)(ying)從螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)群中(zhong)部開始安裝(zhuang)(zhuang)，逐個擰(ning)(ning)(ning)緊(jin)(jin)。初擰(ning)(ning)(ning)、復擰(ning)(ning)(ning)、終擰(ning)(ning)(ning)都應(ying)(ying)從螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)群中(zhong)部向四周擴展(zhan)逐個擰(ning)(ning)(ning)緊(jin)(jin)，每擰(ning)(ning)(ning)一遍均應(ying)(ying)用(yong)不同(tong)顏(yan)色的(de)(de)(de)油漆做上標(biao)記，防止漏(lou)擰(ning)(ning)(ning)。安裝(zhuang)(zhuang)高(gao)強(qiang)度螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)時(shi)，嚴禁強(qiang)行穿入（如用(yong)錘敲打）。如不能自由穿入時(shi)，該孔(kong)應(ying)(ying)用(yong)絞刀進行修整，修整后更大(da)直徑(jing)應(ying)(ying)小于(yu)1.2倍螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)直徑(jing)。修孔(kong)時(shi)，為了防止鐵銷(xiao)落入板疊縫中(zhong)，應(ying)(ying)將四周的(de)(de)(de)螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)全部擰(ning)(ning)(ning)緊(jin)(jin)，板疊縫緊(jin)(jin)貼后再進行絞孔(kong)。嚴禁用(yong)氣割(ge)擴孔(kong)。安裝(zhuang)(zhuang)高(gao)強(qiang)度螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)時(shi)，構(gou)件(jian)(jian)的(de)(de)(de)摩擦面(mian)應(ying)(ying)保持干臊，不得在(zai)雨中(zhong)作(zuo)業(ye)。高(gao)強(qiang)度螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)在(zai)終擰(ning)(ning)(ning)以后，螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)絲(si)扣(kou)(kou)外露應(ying)(ying)為2至3扣(kou)(kou)，其中(zhong)允許有10%的(de)(de)(de)螺(luo)(luo)(luo)(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)絲(si)扣(kou)(kou)外露1扣(kou)(kou)或(huo)4扣(kou)(kou)。

      當然以(yi)后(hou)工業風(feng)(feng)扇結構件螺栓(shuan)的連(lian)接(jie)只是做以(yi)保護(hu)，更多(duo)的還是會使用大王通(tong)風(feng)(feng)特有的漲緊裝置形成結構性自鎖，或者隨著技術發(fa)展采用更為先進的連(lian)接(jie)方式，保證(zheng)工業風(feng)(feng)扇運行時(shi)的安(an)全。

At present, the connection between the output shaft and the wheel hub of Industrial Fan Motors on the market is divided into two types, one is the high-strength bolt connection, and the other is the structural self-locking of the tensioning device, even if the bolt at the output shaft end is loose, the hub and the output shaft can still be securely fastened together. Whether it is bolt connection, or structural self-locking and bolt connection, we can find common ground, will install bolts, so now talk about high-strength bolt safety methods. The installation of high-strength bolts should be carried out after the adjustment of the central position of the structural components of industrial fans. The side of the nut with the round countertop shall be oriented to the chamfered side of the Washer when the high-strength bolt joint fittings are assembled. The chamfered side of the Washer under the bolt head shall be facing the bolt head when assembling the high-strength Bolt Joint. High-strength bolts on one joint shall be installed from the middle of the Bolt Group and tightened one by one. The initial screw, the compound screw, the final screw should be from the middle of the bolt group to expand around one by one screw, each screw a different color of paint should be used to mark, to prevent screw leakage. When installing high-strength bolts, do not force through (E. G. BY HAMMERING) . If the hole can not be penetrated freely, the reamer should be used for trimming. The maximum diameter after trimming should be less than 1.2 times the diameter of the bolt. In order to prevent the Iron Pin from falling into the lamination seam, all the bolts around should be tightened, and the lamination seam should be pressed against the reaming hole. Gas Cutting and reaming is strictly prohibited. When installing high-strength bolts, the friction surface of components should be kept dry and should not be operated in the rain. After final tightening of high-strength Bolts, the bolts should be exposed to 2 to 3 buttons, which allows 10% of the bolts exposed to 1 or 4 buttons. Of course, in the future, the bolt connection of the structural parts of industrial fans will only be used for protection. More and more people will use the special tensioning device of king ventilation to form structural self-locking, or adopt more advanced connecting methods with the development of technology, to ensure the safety of industrial fan operation.
