1.減速(su)(su)機使用系(xi)數(shu)(fB) : fB=減速(su)(su)機額定(ding)功率÷減速(su)(su)機所配電機功率
2.減(jian)速機額(e)定(ding)功(gong)(gong)率(lv)：標準工況(kuang)(kuang)條件（工況(kuang)(kuang)系(xi)數fB總(zong)=1）下，確(que)保減(jian)速機使用壽(shou)命(ming)（一般(ban)10000小(xiao)時），減(jian)速機所能配(pei)置的(de)(de)最大功(gong)(gong)率(lv)即為減(jian)速機的(de)(de)額(e)定(ding)功(gong)(gong)率(lv)。減(jian)速機額(e)定(ding)功(gong)(gong)率(lv)由減(jian)速機最薄弱部分決定(ding)。如齒輪減(jian)速機的(de)(de)最小(xiao)齒軸，擺(bai)線減(jian)速機的(de)(de)電機軸或偏心軸承等。
3.標準工(gong)(gong)況條件（fB總=1）：指載荷平穩，無沖擊振動(dong)，每(mei)日工(gong)(gong)作不超過10小(xiao)(xiao)時，每(mei)小(xiao)(xiao)時起動(dong)次(ci)數小(xiao)(xiao)于10次(ci)，環(huan)境溫度20℃左右(you)，潤滑良好，減速機經(jing)過較充分跑合條件下的(de)工(gong)(gong)況。此時的(de)工(gong)(gong)況系數fB總=1。
4. 工況(kuang)系數(shu)： 由(you)工作性質和環境所決定的,在使用時減速(su)機必(bi)須參考的重要參數(shu)。
5.總(zong)(zong)的(de)工(gong)(gong)(gong)(gong)(gong)況系(xi)數(shu)(shu)(fB總(zong)(zong))包括： 1.負載(zai)性(xing)質、工(gong)(gong)(gong)(gong)(gong)作(zuo)時(shi)間、起(qi)動頻(pin)率所(suo)決定(ding)的(de)工(gong)(gong)(gong)(gong)(gong)況系(xi)數(shu)(shu)——也稱必要工(gong)(gong)(gong)(gong)(gong)況系(xi)數(shu)(shu)(fBL)。詳(xiang)細參數(shu)(shu)可查詢麥(mai)德勒產品使用手冊《工(gong)(gong)(gong)(gong)(gong)作(zuo)機系(xi)數(shu)(shu)表》； 2.環境溫度所(suo)決定(ding)的(de)工(gong)(gong)(gong)(gong)(gong)況系(xi)數(shu)(shu)(fB1)； 3.每(mei)小(xiao)時(shi)運行時(shi)間所(suo)決定(ding)的(de)工(gong)(gong)(gong)(gong)(gong)況系(xi)數(shu)(shu)(fB2)； fB總(zong)(zong)= fBL× fB1× fB2
6.產品選(xuan)型(xing)條(tiao)(tiao)件： 為了(le)保證減速(su)機在(zai)不同的工(gong)況條(tiao)(tiao)件下(xia)達到正常使(shi)用(yong)壽命，必須滿足以下(xia)條(tiao)(tiao)件：產品使(shi)用(yong)系數(shu)fB大于(yu)產品所使(shi)用(yong)條(tiao)(tiao)件的工(gong)況系數(shu)fB總。 因此，正常情(qing)況下(xia)，我們在(zai)進行產品選(xuan)型(xing)時，一定要做(zuo)到所選(xuan)產品在(zai)其所配電機功率及速(su)比條(tiao)(tiao)件下(xia)的使(shi)用(yong)系數(shu)大于(yu)1.0。
