K系(xi)列減速(su)電機齒輪(lun)軸(zhou)部(bu)(bu)件精(jing)度(du)控制。K系(xi)列減速(su)電機，齒輪(lun)軸(zhou)大多采用低碳(tan)(tan)合(he)金鋼(gang)經(jing)滲(shen)碳(tan)(tan)，淬火(huo)工藝制造，或采用氮化鋼(gang)經(jing)氮化處理制造，滲(shen)碳(tan)(tan)、淬火(huo)工藝制造的(de)錐齒輪(lun)減速(su)速(su)的(de)齒輪(lun)表面硬(ying)度(du)高(gao)，齒面滲(shen)碳(tan)(tan)層均勻，心部(bu)(bu)韌性(xing)好(hao)，抗沖擊，特別適用于低速(su)重載齒輪(lun)傳動，與軟齒面相(xiang)比較，硬(ying)齒面齒輪(lun)跑合(he)能力較差，必須在(zai)加(jia)工時控制K系(xi)列減速(su)電機齒形及(ji)表面粗糙度(du)的(de)精(jing)度(du)，因為(wei)齒向，齒廓(kuo)誤差及(ji)表面粗糙度(du)直接影響齒面嚙合(he)精(jing)度(du)，因此(ci)可以通過提高(gao)制造精(jing)度(du)來保證載荷沿齒寬(kuan)的(de)均勻分(fen)布。
