減速器的選用方法
1.確定減速器的公稱(chēng)傳動(dòng)比iN
計(jì)算傳動(dòng)比
is=n1/n2
 式中:is一要求的傳動(dòng)比;
n1一輸入轉(zhuǎn)速,r/min
n2一輸出軸轉(zhuǎn)速,r/min
根據(jù)要求的傳動(dòng)比is,選取減速器的公稱(chēng)傳動(dòng)比iNo
2.確定減速器的公稱(chēng)輸入功率PN, PN≥PS
PS≥P2×f1×f2
ps一計(jì)算功率
式中:p2一工作機(jī)的額定功率kw;
     f1一工作機(jī)系數(shù),根據(jù)工作機(jī)構(gòu)的載荷善和利用等級(jí)由表A選。▍⒄誈B/T3811附錄N);
      f2一修正系數(shù),一般f2=1.15
 3.校核減速器的最大負(fù)荷Pmax,pN≥Pmax
Pmax≥Mn×0n1×f3/9550
 式中:Mn一電動(dòng)機(jī)的額定轉(zhuǎn)矩Nm;
f3一峰值轉(zhuǎn)矩系數(shù),根據(jù)工作機(jī)構(gòu)的載荷狀況的利用等級(jí)由表A選取。
4.根據(jù)iN和pn從功率表(表達(dá)10或11)中選取減速器的規(guī)格型號(hào)。
例:一臺(tái)起重量為32t,跨度22.5m連續(xù)卸用抓橋式起重機(jī);其主起升機(jī)構(gòu)需靜功率為50kw,起升速度為8m/min,轉(zhuǎn)速為18.5r/min,機(jī)構(gòu)工作級(jí)別m7;起升電動(dòng)機(jī)額定功率為60kw,轉(zhuǎn)速750r/min。試選擇減速器(底座式,第Ⅲ種裝配形式,齒輪軸端)。
1)計(jì)算傳動(dòng)比;
選in=40,三級(jí)傳動(dòng):
2)確定減速器的額定輸入功率:
is=n1/n2=750/18.5=40.5
由GB/T3811附錄N,工作級(jí)別為M7的連續(xù)裝卸用抓斗橋式起重機(jī),其主起機(jī)構(gòu)利用等級(jí)為T6,載荷狀況為L3,查表A,得f1=1.2。f2=1.15
PS=60×1.2×1.15=82.8(KW)
當(dāng)n=750r/min,In=400mm,減速器高速軸許用功率PN=103.5KW接近PS=82.8KW,滿足要求。
3)校核減速器的最大負(fù)荷:
電動(dòng)機(jī)額定轉(zhuǎn)矩:
MN=9550×XP1/n1=9550×60/750=764(NM)
由l3-T6-M7查表A,起升機(jī)構(gòu)f3=1.0
Pmax=(MN×n1×f3)/9550=(764×750×1)/9550=60(kW) 
pn=103.5 kw>pmax=60kw,滿足要求,故選型QY3D400-40ⅢC
表A:工作機(jī)系數(shù)f1,尖峰轉(zhuǎn)矩系數(shù)f3
