一、行星減速機傳動(dong)原理

　　行(xing)星(xing)(xing)(xing)減(jian)速(su)(su)機(ji)之傳動(dong)結構為(wei)為(wei)目(mu)前齒(chi)(chi)(chi)輪(lun)(lun)減(jian)速(su)(su)機(ji)效率最高之組(zu)合，其基本傳動(dong)結構為(wei)太(tai)陽齒(chi)(chi)(chi)輪(lun)(lun)、行(xing)星(xing)(xing)(xing)齒(chi)(chi)(chi)輪(lun)(lun)、內齒(chi)(chi)(chi)輪(lun)(lun)環(huan)、階段齒(chi)(chi)(chi)輪(lun)(lun)。驅動(dong)源以(yi)直結或連(lian)接(jie)的(de)(de)方式啟動(dong)太(tai)陽齒(chi)(chi)(chi)輪(lun)(lun)，太(tai)陽齒(chi)(chi)(chi)輪(lun)(lun)將組(zu)合于行(xing)星(xing)(xing)(xing)架上的(de)(de)行(xing)星(xing)(xing)(xing)齒(chi)(chi)(chi)輪(lun)(lun)帶動(dong)運轉。整租行(xing)星(xing)(xing)(xing)齒(chi)(chi)(chi)輪(lun)(lun)系統沿著外齒(chi)(chi)(chi)輪(lun)(lun)環(huan)自轉繞行(xing)轉動(dong)，行(xing)星(xing)(xing)(xing)架連(lian)接(jie)出(chu)力軸輸出(chu)達到減(jian)速(su)(su)目(mu)的(de)(de)。更高減(jian)速(su)(su)比由多(duo)組(zu)階段齒(chi)(chi)(chi)輪(lun)(lun)與行(xing)星(xing)(xing)(xing)齒(chi)(chi)(chi)輪(lun)(lun)倍增(zeng)累計而成(cheng)。

　　二(er)、行星減速機之(zhi)特性

　　1、高扭(niu)力耐沖(chong)擊

　　行(xing)(xing)星(xing)齒(chi)輪(lun)(lun)之(zhi)結構不同于(yu)傳(chuan)統(tong)平(ping)行(xing)(xing)齒(chi)輪(lun)(lun)之(zhi)結構。傳(chuan)統(tong)齒(chi)輪(lun)(lun)依靠倆個齒(chi)輪(lun)(lun)間極少點(dian)接(jie)觸(chu)(chu)面(mian)擠壓(ya)驅動，所有(you)(you)負荷(he)集中于(yu)相接(jie)觸(chu)(chu)之(zhi)少數(shu)齒(chi)輪(lun)(lun)面(mian)，容易產生齒(chi)輪(lun)(lun)之(zhi)摩擦與斷裂。而(er)(er)行(xing)(xing)星(xing)減速(su)機具有(you)(you)更大面(mian)積齒(chi)輪(lun)(lun)接(jie)觸(chu)(chu)面(mian)360度負荷(he)，多個齒(chi)輪(lun)(lun)面(mian)共同均勻承受瞬間沖擊負荷(he)，使其能承受較高(gao)扭力之(zhi)沖擊，本(ben)體及各軸承零件亦不因高(gao)負荷(he)而(er)(er)損壞(huai)斷裂。

　　2、體積小重量輕

　　傳統(tong)齒(chi)輪(lun)減(jian)(jian)速(su)機階由(you)多組大(da)(da)小(xiao)(xiao)齒(chi)輪(lun)偏向交錯(cuo)傳動(dong)減(jian)(jian)速(su)，由(you)于減(jian)(jian)速(su)比須由(you)倆(lia)個齒(chi)輪(lun)之倍數(shu)(shu)比產生(sheng)，大(da)(da)小(xiao)(xiao)齒(chi)輪(lun)間(jian)更(geng)(geng)要(yao)有一定之間(jian)距咬合(he)，因此齒(chi)箱(xiang)容納空間(jian)極大(da)(da);尤(you)其高減(jian)(jian)速(su)比的(de)組合(he)時3更(geng)(geng)要(yao)有倆(lia)臺(tai)以(yi)上減(jian)(jian)速(su)齒(chi)箱(xiang)連接組合(he)，結(jie)構強(qiang)度(du)相對(dui)較(jiao)弱更(geng)(geng)使齒(chi)箱(xiang)長度(du)加長，造(zao)成體積與重(zhong)量及其龐大(da)(da)。行星(xing)減(jian)(jian)速(su)機的(de)結(jie)構可以(yi)需求(qiu)段數(shu)(shu)重(zhong)復連結(jie)，單獨完成多段組合(he)，體積小(xiao)(xiao)、重(zhong)量輕、外形輕巧，相對(dui)使設(she)備更(geng)(geng)有價值感。

　　3、高(gao)效率低背(bei)隙

　　由于齒(chi)(chi)(chi)(chi)輪減速(su)機每一組齒(chi)(chi)(chi)(chi)輪減速(su)傳動(dong)時(shi)只有單(dan)齒(chi)(chi)(chi)(chi)面咬合接觸，當傳動(dong)相(xiang)同扭力時(shi)需要更大(da)(da)齒(chi)(chi)(chi)(chi)面應(ying)力，因此(ci)齒(chi)(chi)(chi)(chi)輪設(she)計必(bi)須采用更大(da)(da)之模數(shu)與厚(hou)度(du)，齒(chi)(chi)(chi)(chi)輪模數(shu)越大(da)(da)，齒(chi)(chi)(chi)(chi)間(jian)偏轉公差值(zhi)越大(da)(da)，相(xiang)對(dui)形(xing)成(cheng)較高齒(chi)(chi)(chi)(chi)輪間(jian)隙各段(duan)減速(su)比(bi)之間(jian)的累(lei)計背(bei)隙隨之增加。而行(xing)星(xing)齒(chi)(chi)(chi)(chi)輪組合中特有的多點均勻密和(he)，外齒(chi)(chi)(chi)(chi)輪環的圓弧(hu)包絡結(jie)構，使(shi)外齒(chi)(chi)(chi)(chi)輪環與行(xing)星(xing)齒(chi)(chi)(chi)(chi)輪間(jian)緊(jin)密結(jie)合，齒(chi)(chi)(chi)(chi)輪間(jian)密合度(du)高，除了(le)提升極(ji)高之減速(su)機效率值(zhi)外，設(she)備本身(shen)更可達到高定(ding)位(wei)選用。
