QY3D400硬齒面齒輪減速器箱體分為上下兩部分,為鋼板焊接箱體,鋼板厚為20MM,此減速機負載大,強度要求高,批量使用較少,所以使用鋼板焊接箱體,即節約了成本,又增加了強度及扭力,焊接后,還需進行回火處理。內部齒輪齒軸采用優質低碳合金鋼,滲碳淬火磨齒加工處理,齒邊角進行修緣處理,每級齒輪的綜合傳動效率達0。98,振動和噪聲顯著降低。
QY3D400硬齒面齒輪減速器為起重機專用減速機,適用于起重機各運行機構中,承載能力大,體積小,重量輕,多級數,拉開中心距,降低減速器整機高度,滿足起重機各機構的要求。
QY3D400硬齒面齒輪減速器傳動比有:QY3D400-16,QY3D400-18,QY3D400-20,QY3D400-22.4,QY3D400-25,QY3D400-28,QY3D400-31.5,QY3D400-35.5,QY3D400-40,QY3D400-45,QY3D400-50,QY3D400-56,QY3D400-63,QY3D400-71,QY3D400-80,QY3D400-90,每一傳動比有九種裝配型式,高速軸端采用圓柱軸伸,平鍵聯接,低速軸端有三種型式,P型圓柱型軸伸,C型齒輪軸伸,H花鍵軸伸,滿足各種工況要求。
