旋(xuan)轉(zhuan)(zhuan)(zhuan)頂(ding)部(bu)(bu)(bu)有很(hen)多(duo)(duo)種，我們根據具(ju)體(ti)情況選(xuan)擇(ze)(ze)不同的(de)旋(xuan)轉(zhuan)(zhuan)(zhuan)頂(ding)部(bu)(bu)(bu)。選(xuan)擇(ze)(ze)旋(xuan)轉(zhuan)(zhuan)(zhuan)頂(ding)部(bu)(bu)(bu)尋(xun)找鈦(tai)浩(hao)，旋(xuan)轉(zhuan)(zhuan)(zhuan)頂(ding)部(bu)(bu)(bu)耐磨性(xing)(xing)很(hen)高，使(shi)用(yong)(yong)(yong)旋(xuan)轉(zhuan)(zhuan)(zhuan)頂(ding)部(bu)(bu)(bu)不會損壞，旋(xuan)轉(zhuan)(zhuan)(zhuan)頂(ding)部(bu)(bu)(bu)經(jing)(jing)常用(yong)(yong)(yong)于一些(xie)大(da)型設備，使(shi)用(yong)(yong)(yong)旋(xuan)轉(zhuan)(zhuan)(zhuan)頂(ding)部(bu)(bu)(bu)注(zhu)意(yi)日(ri)常維護，以確(que)保(bao)(bao)機(ji)(ji)械(xie)的(de)正(zheng)常運行。齒(chi)(chi)輪(lun)加(jia)(jia)(jia)工輪(lun)調(diao)質(zhi)(zhi)的(de)目的(de)是改變(bian)齒(chi)(chi)輪(lun)材料的(de)綜(zong)合機(ji)(ji)械(xie)性(xing)(xing)能(neng)。調(diao)質(zhi)(zhi)后(hou)的(de)硬度(du)不高，一般在HBS200-240左右，與調(diao)質(zhi)(zhi)前的(de)材料硬度(du)差(cha)別不大(da)，但(dan)機(ji)(ji)械(xie)性(xing)(xing)能(neng)要好得多(duo)(duo)。同時(shi)(shi)(shi)，還(huan)能(neng)保(bao)(bao)證熱(re)處理質(zhi)(zhi)量(liang)，韌性(xing)(xing)好，易跑合，能(neng)補償制造誤差(cha)。那么(me)在調(diao)質(zhi)(zhi)齒(chi)(chi)輪(lun)夾具(ju)時(shi)(shi)(shi)需要注(zhu)意(yi)哪些(xie)方面呢(ni)？1.在淬(cui)(cui)火(huo)過程中，齒(chi)(chi)輪(lun)加(jia)(jia)(jia)工容易產生淬(cui)(cui)火(huo)裂紋，從而(er)影(ying)響齒(chi)(chi)輪(lun)的(de)使(shi)用(yong)(yong)(yong)性(xing)(xing)能(neng)甚(shen)至報(bao)廢。為(wei)防止淬(cui)(cui)火(huo)，應采取降(jiang)低淬(cui)(cui)火(huo)應力的(de)措施，如冷(leng)(leng)淬(cui)(cui)火(huo)、正(zheng)確(que)選(xuan)擇(ze)(ze)淬(cui)(cui)火(huo)介質(zhi)(zhi)、控制冷(leng)(leng)卻(que)(que)時(shi)(shi)(shi)間(jian)(jian)等。淬(cui)(cui)火(huo)介質(zhi)(zhi)盡量(liang)選(xuan)用(yong)(yong)(yong)水(shui)(shui)淬(cui)(cui)，水(shui)(shui)淬(cui)(cui)可(ke)獲得較深(shen)的(de)淬(cui)(cui)硬層和令人滿意(yi)的(de)心(xin)臟(zang)組織。當(dang)水(shui)(shui)淬(cui)(cui)有危險(xian)時(shi)(shi)(shi)，考(kao)慮采取油(you)(you)(you)淬(cui)(cui)或水(shui)(shui)淬(cui)(cui)油(you)(you)(you)冷(leng)(leng)的(de)措施。冷(leng)(leng)卻(que)(que)時(shi)(shi)(shi)間(jian)(jian)過長(chang)，也可(ke)能(neng)是由于溫度(du)過低，使(shi)內(nei)應力過大(da)，使(shi)齒(chi)(chi)輪(lun)淬(cui)(cui)火(huo)，一般冷(leng)(leng)卻(que)(que)時(shi)(shi)(shi)間(jian)(jian)的(de)選(xuan)擇(ze)(ze)，是心(xin)冷(leng)(leng)到MS點附近（約300攝氏度(du)）。在實際(ji)操作中，心(xin)臟(zang)溫度(du)是無法測量(liang)的(de)，這取決于操作人員的(de)實踐經(jing)(jing)驗。2.淬(cui)(cui)火(huo)后(hou)必須及時(shi)(shi)(shi)回火(huo)齒(chi)(chi)輪(lun)加(jia)(jia)(jia)工，防止應力過大(da)導致齒(chi)(chi)輪(lun)開裂。對(dui)回火(huo)脆性(xing)(xing)敏感的(de)齒(chi)(chi)輪(lun)材料，回火(huo)時(shi)(shi)(shi)油(you)(you)(you)冷(leng)(leng)，增加(jia)(jia)(jia)一次消除應力的(de)回火(huo)。對(dui)于淬(cui)(cui)透(tou)性(xing)(xing)高的(de)齒(chi)(chi)輪(lun)鋼，如40crnimo，用(yong)(yong)(yong)鹽(yan)浴加(jia)(jia)(jia)熱(re)，淬(cui)(cui)火(huo)后(hou)不能(neng)過早清(qing)理鹽(yan)渣(zha)，否則由于清(qing)洗過程中冷(leng)(leng)卻(que)(que)的(de)熱(re)應力和內(nei)部(bu)(bu)(bu)過冷(leng)(leng)奧氏體(ti)轉(zhuan)(zhuan)(zhuan)變(bian)引起的(de)內(nei)應力，齒(chi)(chi)輪(lun)開裂。
