在采購、選型減速機是要對齒輪減速機的傳動(dong)效(xiao)率有一定的了解(jie)，以方便選(xuan)型，下面兆威機電簡單的闡述傳動(dong)效(xiao)率介(jie)紹和計算公式；

  齒(chi)輪減速(su)(su)機(ji)(ji)的(de)(de)傳(chuan)(chuan)動(dong)(dong)效(xiao)率(lv)(lv)(lv)通常是(shi)指在(zai)額(e)定(ding)輸(shu)(shu)入轉速(su)(su)下達到(dao)額(e)定(ding)輸(shu)(shu)入功(gong)(gong)率(lv)(lv)(lv)（或輸(shu)(shu)入轉矩(ju)）時，輸(shu)(shu)出功(gong)(gong)率(lv)(lv)(lv)（或輸(shu)(shu)出轉矩(ju)）對額(e)定(ding)輸(shu)(shu)入功(gong)(gong)率(lv)(lv)(lv)（或輸(shu)(shu)入轉矩(ju)乘以傳(chuan)(chuan)動(dong)(dong)比(bi)(bi)）的(de)(de)比(bi)(bi)值。齒(chi)輪減速(su)(su)機(ji)(ji)傳(chuan)(chuan)動(dong)(dong)效(xiao)率(lv)(lv)(lv)的(de)(de)測(ce)(ce)量應在(zai)專用的(de)(de)試驗臺上(shang)(shang)進行，測(ce)(ce)試方(fang)法(fa)可(ke)分為直(zhi)(zhi)測(ce)(ce)功(gong)(gong)率(lv)(lv)(lv)法(fa)和損(sun)失功(gong)(gong)率(lv)(lv)(lv)法(fa)，直(zhi)(zhi)測(ce)(ce)功(gong)(gong)率(lv)(lv)(lv)法(fa)又分為單臺直(zhi)(zhi)測(ce)(ce)功(gong)(gong)率(lv)(lv)(lv)法(fa)和雙臺直(zhi)(zhi)測(ce)(ce)功(gong)(gong)率(lv)(lv)(lv)法(fa)。單臺直(zhi)(zhi)測(ce)(ce)功(gong)(gong)率(lv)(lv)(lv)法(fa)是(shi)在(zai)試驗裝(zhuang)置臺上(shang)(shang)，用儀器(qi)直(zhi)(zhi)接測(ce)(ce)量減速(su)(su)機(ji)(ji)的(de)(de)輸(shu)(shu)入、輸(shu)(shu)出轉矩(ju)和轉速(su)(su)，來確定(ding)效(xiao)率(lv)(lv)(lv)的(de)(de)方(fang)法(fa)。可(ke)以有較(jiao)大(da)的(de)(de)減速(su)(su)比(bi)(bi)，輸(shu)(shu)入軸(zhou)和輸(shu)(shu)出軸(zhou)不(bu)在(zai)同(tong)一軸(zhou)線上(shang)(shang)，也不(bu)在(zai)同(tong)一平(ping)面(mian)上(shang)(shang)。但是(shi)一般體積較(jiao)大(da)，傳(chuan)(chuan)動(dong)(dong)效(xiao)率(lv)(lv)(lv)不(bu)，精(jing)度不(bu)。
