然后在(zai)車床刀架上(shang)裝(zhuang)置(zhi)一(yi)小磨頭,對線切(qie)(qie)割局部停止磨削(xue),肯定根本尺寸(cun)(cun),拆下(xia)后在(zai)加(jia)(jia)工面上(shang)軸(zhou)向劃(hua)三等分(fen)線,用1。0mm切(qie)(qie)割片(pian)在(zai)軸(zhou)向磨出3道深0。5mm溝槽,為(wei)再次(ci)上(shang)線切(qie)(qie)割機穿絲工藝用。與此(ci)同(tong)時,加(jia)(jia)工一(yi)件Gr15熱處置(zhi)硬度達HRC58-62的輪內(nei)孔(kong)(kong)套,內(nei)孔(kong)(kong)尺寸(cun)(cun)比外(wai)孔(kong)(kong)尺小0。5mm,外(wai)圓磨削(xue)后外(wai)表粗糙度到達Ra0。08,外(wai)徑尺寸(cun)(cun)為(wei)φ5±0。005mm,厚(hou)度與輪厚(hou)分(fen)歧,壓入擺線輪內(nei)孔(kong)(kong),上(shang)線切(qie)(qie)割機加(jia)(jia)工三個φ2的銷孔(kong)(kong),配(pei)上(shang)銷子(zi),再上(shang)車床應用四爪卡盤找正,平行(xing)度0。01mm,同(tong)心度0。01mm,磨削(xue)內(nei)孔(kong)(kong)至規范配(pei)合尺寸(cun)(cun)精度,拆下(xia)行(xing)星(xing)孔(kong)(kong)上(shang)的柱銷,維修(xiu)終了。
關于(yu)請(qing)求特別嚴厲的(de)(de)場所,能夠應用三坐(zuo)標丈量(liang)機(ji)(ji)或工具顯微鏡(jing)對修理(li)件(jian)的(de)(de)誤差停止檢測。擺(bai)線針輪(lun)減(jian)(jian)速(su)機(ji)(ji)的(de)(de)定期(qi)檢查(cha)方面,請(qing)求從四(si)個方面停止定期(qi)檢查(cha):①檢查(cha)減(jian)(jian)速(su)機(ji)(ji)聯合(he)件(jian)的(de)(de)同心度與松緊(jin)度,避(bi)免設備在飛轉矩力氣的(de)(de)作用下(xia)形成損傷。②檢查(cha)減(jian)(jian)速(su)機(ji)(ji)的(de)(de)根本狀況(kuang),包(bao)括裝置根底、固定螺(luo)絲(si)以及運(yun)轉情(qing)況(kuang),要(yao)保證減(jian)(jian)速(su)機(ji)(ji)的(de)(de)均衡運(yun)動,及時調整不(bu)合(he)理(li)的(de)(de)中央。
③定期換油,換油的同時要將減速機的相關設備清洗潔凈;檢查減速機的油量,保證減速機的正常運轉。拆機檢驗和掃除毛病先將輸出局部與減速局部聯接螺絲松開,機座單獨取出,這樣能夠單獨檢驗輸出軸、出軸銷和機座;再拆下減速局部的擺線輪、偏心套、針齒殼、隔離環;余下的是輸入局部的電機或端蓋輸入軸。1)減速局部的軸系毛病
從輸入(ru)(ru)局部(bu)開端(duan),先檢驗電(dian)機有無竄軸,軸承點小或(huo)軸承室大。若有則維修或(huo)改換零部(bu)件(jian),將使電(dian)機到達(da)單(dan)機運轉(zhuan)聲(sheng)音正常,轉(zhuan)子軸自轉(zhuan)跳動≤0。01mm,以轉(zhuan)子旋轉(zhuan)中(zhong)心為基準(zhun),用(yong)百(bai)分表(biao)丈量電(dian)機轉(zhuan)子與法(fa)蘭盤端(duan)面的(de)垂直度≤0。035mm,與止口的(de)同(tong)心度≤0。035mm。輸入(ru)(ru)端(duan)的(de)輸入(ru)(ru)軸和(he)端(duan)蓋請(qing)求也(ye)相同(tong);若不合格(ge),這些(xie)件(jian)均(jun)可上(shang)車床(chuang)找(zhao)正后配套裝入(ru)(ru),再找(zhao)正檢驗停止處置。
