6.減速器承載能力與選用方法
①減速器輸出軸軸端許用負(fù)荷取決于蝸輪軸的轉(zhuǎn)速及額定扭矩。按下式計算。
FR=fLR
FA=fLA
式中FR——輸出軸軸端徑向許用負(fù)荷,見表8-133圖中的a;
FA——輸出軸軸端軸向許用負(fù)荷,見表8-133圖中的b;
fL——速度系數(shù),其值應(yīng)符合表8-133的規(guī)定;
R——徑向載荷系數(shù),其值見表8-132;
A——軸向載荷系數(shù),其值見表8-132。
②表8-129額定輸入功率P1及額定輸出扭矩T2適用于CWU,CWS型減速器,工作載荷平穩(wěn)平?jīng)_擊,每日工作8h,每小時啟動10次,啟動扭矩為輸出扭矩的2.5倍,小時負(fù)荷率JC=100%環(huán)境溫度為20℃。
