一、螺桿是什么東西

螺(luo)(luo)桿是一(yi)種圓(yuan)柱形(xing)零件，表面上有(you)一(yi)圈螺(luo)(luo)旋線，多用于同(tong)心度較高的圓(yuan)筒工(gong)作件上，進行(xing)固定、連接或(huo)傳(chuan)動。

二、螺桿有什么作用

螺桿的(de)主(zhu)要(yao)作用是將(jiang)旋轉運(yun)(yun)動轉換為(wei)直(zhi)線運(yun)(yun)動或者將(jiang)力的(de)方向轉化，以滿足不同的(de)工業需求(qiu)。

在(zai)(zai)(zai)工(gong)(gong)業生產中(zhong)，螺桿(gan)(gan)被廣泛應(ying)用(yong)(yong)(yong)(yong)(yong)于(yu)各(ge)類(lei)機(ji)(ji)(ji)械(xie)裝置(zhi)(zhi)(zhi)中(zhong)，如(ru)工(gong)(gong)程機(ji)(ji)(ji)械(xie)、電(dian)(dian)動(dong)(dong)(dong)(dong)工(gong)(gong)具(ju)、風力發電(dian)(dian)機(ji)(ji)(ji)、石油化(hua)(hua)工(gong)(gong)及(ji)鋼鐵冶金等(deng)多個領域。例如(ru)：從(cong)事機(ji)(ji)(ji)械(xie)加工(gong)(gong)的人(ren)員都(dou)熟知，螺桿(gan)(gan)在(zai)(zai)(zai)機(ji)(ji)(ji)床上的應(ying)用(yong)(yong)(yong)(yong)(yong)能夠將后轉運(yun)(yun)動(dong)(dong)(dong)(dong)轉化(hua)(hua)成前進運(yun)(yun)動(dong)(dong)(dong)(dong)，實(shi)現鉆孔、車(che)削等(deng)工(gong)(gong)作；同(tong)時，在(zai)(zai)(zai)機(ji)(ji)(ji)床運(yun)(yun)動(dong)(dong)(dong)(dong)控制中(zhong)也廣泛應(ying)用(yong)(yong)(yong)(yong)(yong)于(yu)往復運(yun)(yun)動(dong)(dong)(dong)(dong)、轉動(dong)(dong)(dong)(dong)運(yun)(yun)動(dong)(dong)(dong)(dong)、具(ju)有(you)列推力的運(yun)(yun)動(dong)(dong)(dong)(dong)，以及(ji)精密位置(zhi)(zhi)(zhi)傳動(dong)(dong)(dong)(dong)和轉矩(ju)傳遞(di)，這(zhe)一切離不(bu)開(kai)螺桿(gan)(gan)的應(ying)用(yong)(yong)(yong)(yong)(yong)。此外，螺桿(gan)(gan)還被用(yong)(yong)(yong)(yong)(yong)于(yu)鋼鐵水泥冶金等(deng)領域中(zhong)，用(yong)(yong)(yong)(yong)(yong)于(yu)多種(zhong)不(bu)同(tong)場所的位置(zhi)(zhi)(zhi)傳動(dong)(dong)(dong)(dong)、轉矩(ju)傳遞(di)和工(gong)(gong)件定位，具(ju)有(you)不(bu)可替代的重要作用(yong)(yong)(yong)(yong)(yong)。
