一、螺桿是什么東西

螺桿是一(yi)(yi)種圓柱(zhu)形零件(jian)，表面(mian)上(shang)有一(yi)(yi)圈螺旋線(xian)，多(duo)用(yong)于(yu)同(tong)心度較高的圓筒工作件(jian)上(shang)，進(jin)行固定、連接或傳動。

二、螺桿有什么作用

螺桿的主要作用是將旋轉(zhuan)運動轉(zhuan)換為直線運動或者將力(li)的方向轉(zhuan)化，以滿足不(bu)同的工業需求。

在工(gong)(gong)(gong)(gong)(gong)業生(sheng)產中(zhong)(zhong)，螺桿(gan)被(bei)廣泛(fan)應(ying)(ying)用(yong)于各類機(ji)(ji)械裝(zhuang)置(zhi)中(zhong)(zhong)，如工(gong)(gong)(gong)(gong)(gong)程機(ji)(ji)械、電動(dong)(dong)(dong)(dong)(dong)工(gong)(gong)(gong)(gong)(gong)具、風力發電機(ji)(ji)、石油化工(gong)(gong)(gong)(gong)(gong)及(ji)鋼(gang)鐵冶(ye)金(jin)等(deng)多個領(ling)域(yu)。例如：從事機(ji)(ji)械加工(gong)(gong)(gong)(gong)(gong)的人(ren)員(yuan)都熟知，螺桿(gan)在機(ji)(ji)床上(shang)的應(ying)(ying)用(yong)能夠將后轉(zhuan)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)轉(zhuan)化成前進運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)，實(shi)現(xian)鉆(zhan)孔、車削(xue)等(deng)工(gong)(gong)(gong)(gong)(gong)作；同時(shi)，在機(ji)(ji)床運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)控制中(zhong)(zhong)也廣泛(fan)應(ying)(ying)用(yong)于往復運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)、轉(zhuan)動(dong)(dong)(dong)(dong)(dong)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)、具有列推力的運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)，以及(ji)精密位(wei)置(zhi)傳動(dong)(dong)(dong)(dong)(dong)和轉(zhuan)矩(ju)傳遞(di)，這一切離不(bu)開螺桿(gan)的應(ying)(ying)用(yong)。此(ci)外，螺桿(gan)還被(bei)用(yong)于鋼(gang)鐵水(shui)泥(ni)冶(ye)金(jin)等(deng)領(ling)域(yu)中(zhong)(zhong)，用(yong)于多種不(bu)同場所的位(wei)置(zhi)傳動(dong)(dong)(dong)(dong)(dong)、轉(zhuan)矩(ju)傳遞(di)和工(gong)(gong)(gong)(gong)(gong)件定位(wei)，具有不(bu)可替代的重要(yao)作用(yong)。
