  軸承鋼(gang)的650℃溫(wen)加(jia)(jia)(jia)工(gong)(gong)(gong)也是新(xin)型技術。共(gong)析(xi)鋼(gang)或高碳鋼(gang)熱(re)加(jia)(jia)(jia)工(gong)(gong)(gong)前(qian)若具(ju)有細晶(jing)粒組織(zhi)或在(zai)(zai)加(jia)(jia)(jia)工(gong)(gong)(gong)過程能(neng)(neng)形成細晶(jing)粒，則在(zai)(zai)(0.4～0.6)熔化溫(wen)度(du)范圍內(nei)，在(zai)(zai)一定(ding)應變(bian)速(su)率(lv)下(xia)，呈(cheng)現出超塑性。美(mei)國海軍研究院(NSP)對52100鋼(gang)進(jin)行了650℃溫(wen)加(jia)(jia)(jia)工(gong)(gong)(gong)試驗表明，在(zai)(zai)650℃下(xia)真應變(bian)2.5不發生斷裂。因此，有可能(neng)(neng)以650℃溫(wen)加(jia)(jia)(jia)工(gong)(gong)(gong)來(lai)代替高溫(wen)加(jia)(jia)(jia)工(gong)(gong)(gong)并(bing)與球化退火(huo)工(gong)(gong)(gong)藝結合起來(lai)，這對簡化設備和工(gong)(gong)(gong)序、節約能(neng)(neng)源、進(jin)步(bu)質(zhi)量(liang)有重要意義。

  軸(zhou)承(cheng)振動對軸(zhou)承(cheng)的損傷很敏感，例如剝落、壓痕(hen)、銹(xiu)蝕(shi)、裂(lie)紋(wen)、磨(mo)損等都(dou)會在軸(zhou)承(cheng)及振動測(ce)量中(zhong)反映出來。所以(yi)，通過(guo)采用特殊的軸(zhou)承(cheng)振動測(ce)量器(qi)（頻率分析(xi)器(qi)等）可測(ce)量出振動的大小，。測(ce)得的數值因軸(zhou)承(cheng)的使用條件或(huo)傳感器(qi)安裝位置等而(er)不同，因此(ci)需要事先對每臺(tai)機器(qi)的測(ce)量值進(jin)行分析(xi)比較(jiao)后(hou)確(que)定判斷標準。
