精密機械軸、汽配軸、家電軸的常用材料使用
材料使用(yong)(yong)(yong)1、碳(tan)素鋼(gang)(gang)(gang)(gang)(gang)35、45、50等(deng)(deng)碳(tan)素結(jie)(jie)(jie)構(gou)鋼(gang)(gang)(gang)(gang)(gang)因具有(you)較(jiao)(jiao)高的(de)(de)(de)(de)綜(zong)合(he)力(li)(li)學(xue)性(xing)能(neng),應用(yong)(yong)(yong)較(jiao)(jiao)多,其中以45鋼(gang)(gang)(gang)(gang)(gang)用(yong)(yong)(yong)得廣泛(fan)。為了改善其力(li)(li)學(xue)性(xing)能(neng),應進行正(zheng)火(huo)或調(diao)質處(chu)理。不重(zhong)要或受(shou)力(li)(li)較(jiao)(jiao)小的(de)(de)(de)(de)軸(zhou)(zhou),則可(ke)采用(yong)(yong)(yong)Q235、Q275等(deng)(deng)碳(tan)素結(jie)(jie)(jie)構(gou)鋼(gang)(gang)(gang)(gang)(gang)。2、合(he)金(jin)鋼(gang)(gang)(gang)(gang)(gang)合(he)金(jin)鋼(gang)(gang)(gang)(gang)(gang)具有(you)較(jiao)(jiao)高的(de)(de)(de)(de)力(li)(li)學(xue)性(xing)能(neng),但價格較(jiao)(jiao)貴,多用(yong)(yong)(yong)于有(you)特(te)殊要求(qiu)的(de)(de)(de)(de)軸(zhou)(zhou)。例如采用(yong)(yong)(yong)滑(hua)動軸(zhou)(zhou)承(cheng)的(de)(de)(de)(de)高速軸(zhou)(zhou),常(chang)用(yong)(yong)(yong)20Cr、20CrMnTi等(deng)(deng)低(di)(di)碳(tan)合(he)金(jin)結(jie)(jie)(jie)構(gou)鋼(gang)(gang)(gang)(gang)(gang),經滲碳(tan)淬火(huo)后可(ke)提高軸(zhou)(zhou)頸耐磨性(xing);汽(qi)輪發(fa)電機轉子軸(zhou)(zhou)在高溫(wen)、高速和重(zhong)載條(tiao)件下工(gong)作,具有(you)良好的(de)(de)(de)(de)高溫(wen)力(li)(li)學(xue)性(xing)能(neng),常(chang)采用(yong)(yong)(yong)40CrNi、38CrMoAlA等(deng)(deng)合(he)金(jin)結(jie)(jie)(jie)構(gou)鋼(gang)(gang)(gang)(gang)(gang)。軸(zhou)(zhou)的(de)(de)(de)(de)毛坯以鍛(duan)件優先、其次是(shi)圓鋼(gang)(gang)(gang)(gang)(gang);尺寸較(jiao)(jiao)大或結(jie)(jie)(jie)構(gou)復雜者可(ke)考慮(lv)鑄鋼(gang)(gang)(gang)(gang)(gang)或球(qiu)墨鑄鐵。例如,用(yong)(yong)(yong)球(qiu)墨鑄鐵制造曲軸(zhou)(zhou)、凸輪軸(zhou)(zhou),具有(you)成(cheng)本低(di)(di)廉、吸振性(xing)較(jiao)(jiao)好,對(dui)應力(li)(li)集中的(de)(de)(de)(de)敏(min)感性(xing)較(jiao)(jiao)低(di)(di)、強(qiang)度較(jiao)(jiao)好等(deng)(deng)優點(dian)。軸(zhou)(zhou)的(de)(de)(de)(de)力(li)(li)學(xue)模型是(shi)梁、多數要轉動,因此(ci)其應力(li)(li)通(tong)常(chang)是(shi)對(dui)稱循環。其可(ke)能(neng)的(de)(de)(de)(de)失效形式有(you):疲(pi)勞斷(duan)(duan)裂(lie)、過載斷(duan)(duan)裂(lie)、彈性(xing)變形過大等(deng)(deng)。軸(zhou)(zhou)上通(tong)常(chang)要安(an)裝一些帶(dai)輪轂的(de)(de)(de)(de)零(ling)件,因此(ci)大多數軸(zhou)(zhou)應作成(cheng)階梯軸(zhou)(zhou),切削加工(gong)量(liang)大。
