在采購、選型減速機是要對齒輪減速機的驅動效率(lv)(lv)有一(yi)定(ding)的了解，以方便選型，下面兆威機電簡(jian)單(dan)的闡述(shu)驅動效率(lv)(lv)介(jie)紹和計(ji)算(suan)公(gong)式；

  齒(chi)輪減(jian)(jian)速(su)機的(de)(de)(de)驅(qu)動效(xiao)率(lv)(lv)通常是指(zhi)在額定輸(shu)(shu)入(ru)轉(zhuan)速(su)下(xia)達到額定輸(shu)(shu)入(ru)功(gong)(gong)(gong)率(lv)(lv)（或(huo)輸(shu)(shu)入(ru)轉(zhuan)矩）時，輸(shu)(shu)出(chu)功(gong)(gong)(gong)率(lv)(lv)（或(huo)輸(shu)(shu)出(chu)轉(zhuan)矩）對(dui)額定輸(shu)(shu)入(ru)功(gong)(gong)(gong)率(lv)(lv)（或(huo)輸(shu)(shu)入(ru)轉(zhuan)矩乘以驅(qu)動比）的(de)(de)(de)比值。齒(chi)輪減(jian)(jian)速(su)機驅(qu)動效(xiao)率(lv)(lv)的(de)(de)(de)測量(liang)應(ying)在專用的(de)(de)(de)試(shi)驗(yan)(yan)臺(tai)上(shang)進(jin)行，測試(shi)方(fang)法(fa)(fa)(fa)可分為直(zhi)(zhi)測功(gong)(gong)(gong)率(lv)(lv)法(fa)(fa)(fa)和損(sun)失功(gong)(gong)(gong)率(lv)(lv)法(fa)(fa)(fa)，直(zhi)(zhi)測功(gong)(gong)(gong)率(lv)(lv)法(fa)(fa)(fa)又分為單臺(tai)直(zhi)(zhi)測功(gong)(gong)(gong)率(lv)(lv)法(fa)(fa)(fa)和雙(shuang)臺(tai)直(zhi)(zhi)測功(gong)(gong)(gong)率(lv)(lv)法(fa)(fa)(fa)。單臺(tai)直(zhi)(zhi)測功(gong)(gong)(gong)率(lv)(lv)法(fa)(fa)(fa)是在試(shi)驗(yan)(yan)裝置臺(tai)上(shang)，用儀器直(zhi)(zhi)接測量(liang)減(jian)(jian)速(su)機的(de)(de)(de)輸(shu)(shu)入(ru)、輸(shu)(shu)出(chu)轉(zhuan)矩和轉(zhuan)速(su)，來確(que)定效(xiao)率(lv)(lv)的(de)(de)(de)方(fang)法(fa)(fa)(fa)。可以有較大的(de)(de)(de)減(jian)(jian)速(su)比，輸(shu)(shu)入(ru)軸(zhou)和輸(shu)(shu)出(chu)軸(zhou)不(bu)(bu)在同(tong)一(yi)軸(zhou)線上(shang)，也不(bu)(bu)在同(tong)一(yi)平面上(shang)。但(dan)是一(yi)般體積較大，驅(qu)動效(xiao)率(lv)(lv)不(bu)(bu)，精度不(bu)(bu)。

? 下面這組是減速機驅動效率計算公式：

  總(zong)效(xiao)(xiao)率(lv)(lv)(lv)η＝運輸機傳(chuan)送帶效(xiao)(xiao)率(lv)(lv)(lv)η1×運輸機軸承效(xiao)(xiao)率(lv)(lv)(lv)η2×運輸機與減速(su)器(qi)間聯軸器(qi)效(xiao)(xiao)率(lv)(lv)(lv)η3×減速(su)器(qi)內3對(dui)滾動(dong)(dong)軸承效(xiao)(xiao)率(lv)(lv)(lv)η4×2對(dui)圓柱齒(chi)輪嚙合驅動(dong)(dong)效(xiao)(xiao)率(lv)(lv)(lv)η5×電動(dong)(dong)機與減速(su)器(qi)間聯軸器(qi)效(xiao)(xiao)率(lv)(lv)(lv)η6；
