摘要： 本發明公開了一種無空刀槽雙螺旋齒輪的磨削加工方法，在插齒加工后對無空刀槽雙螺旋齒輪中間部分進行鍍層防滲碳熱處理保護，熱處理后進行化學方法去除保護鍍層，然后用蝶形砂輪進(jin)行磨(mo)削加(jia)工(gong)(gong)。由于雙(shuang)螺旋齒(chi)輪(lun)(lun)的(de)(de)(de)中(zhong)間(jian)部(bu)分(fen)沒有(you)滲碳強(qiang)化，可以通(tong)過普(pu)通(tong)的(de)(de)(de)銑削方(fang)法(fa)(fa)切除雙(shuang)螺旋齒(chi)輪(lun)(lun)中(zhong)間(jian)部(bu)分(fen)齒(chi)面(mian)，使得中(zhong)間(jian)部(bu)分(fen)不參與嚙合但有(you)連(lian)接兩側齒(chi)面(mian)提高(gao)強(qiang)度效果。通(tong)過本發明的(de)(de)(de)方(fang)法(fa)(fa)不僅實現了無空刀槽雙(shuang)螺旋齒(chi)輪(lun)(lun)的(de)(de)(de)磨(mo)削加(jia)工(gong)(gong)，相比有(you)空刀槽雙(shuang)螺旋齒(chi)輪(lun)(lun)又提高(gao)了輪(lun)(lun)齒(chi)強(qiang)度。
