精密行(xing)星齒(chi)(chi)(chi)輪(lun)減速機(ji)(ji)中(zhong)齒(chi)(chi)(chi)輪(lun)模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)是(shi)一個(ge)非常重點的(de)(de)(de)知識點，模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)輪(lun)齒(chi)(chi)(chi)越高也越厚，模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)是(shi)指相鄰(lin)兩輪(lun)齒(chi)(chi)(chi)同側齒(chi)(chi)(chi)廓間(jian)的(de)(de)(de)齒(chi)(chi)(chi)距(ju)(ju)t與(yu)圓周率π的(de)(de)(de)比值(m=t/π)以(yi)毫(hao)米為(wei)(wei)單位。模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)是(shi)模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)制(zhi)(zhi)輪(lun)齒(chi)(chi)(chi)的(de)(de)(de)一個(ge)*基本參數(shu)(shu)(shu)(shu)(shu)。模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)越大(da)。如果齒(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)數(shu)(shu)(shu)(shu)(shu)一定(ding)，則輪(lun)的(de)(de)(de)徑向(xiang)尺寸也越大(da)。模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)系(xi)列標準是(shi)根據設計、制(zhi)(zhi)造和檢驗等要求(qiu)制(zhi)(zhi)訂的(de)(de)(de)對於具(ju)有(you)(you)(you)非直(zhi)齒(chi)(chi)(chi)的(de)(de)(de)齒(chi)(chi)(chi)輪(lun)，模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)有(you)(you)(you)法(fa)向(xiang)模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)mn端(duan)面(mian)(mian)模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)ms與(yu)軸(zhou)向(xiang)模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)mx區別，都是(shi)以(yi)各自的(de)(de)(de)齒(chi)(chi)(chi)距(ju)(ju)(法(fa)向(xiang)齒(chi)(chi)(chi)距(ju)(ju)、端(duan)面(mian)(mian)齒(chi)(chi)(chi)距(ju)(ju)與(yu)軸(zhou)向(xiang)齒(chi)(chi)(chi)距(ju)(ju))與(yu)圓周率的(de)(de)(de)比值，行(xing)星齒(chi)(chi)(chi)輪(lun)減速機(ji)(ji)廠家，也都以(yi)毫(hao)米為(wei)(wei)單位。對於錐齒(chi)(chi)(chi)輪(lun)模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)有(you)(you)(you)大(da)端(duan)模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)me平均模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)mm和小端(duan)模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)m1之分。對於刀具(ju)，則有(you)(you)(you)相應(ying)的(de)(de)(de)刀具(ju)模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)mo等，規(gui)范模(mo)(mo)(mo)數(shu)(shu)(shu)(shu)(shu)的(de)(de)(de)應(ying)用很廣。

精(jing)密行(xing)星(xing)減(jian)(jian)(jian)(jian)(jian)速(su)(su)機(ji)(ji)(ji)(ji)和電(dian)(dian)機(ji)(ji)(ji)(ji)搭(da)配(pei)使用是因為：電(dian)(dian)機(ji)(ji)(ji)(ji)和行(xing)星(xing)減(jian)(jian)(jian)(jian)(jian)速(su)(su)機(ji)(ji)(ji)(ji)配(pei)合(he)(he)使用，可(ke)以(yi)增加(jia)扭矩(ju)。當負載(zai)較重時，吉(ji)林行(xing)星(xing)齒輪減(jian)(jian)(jian)(jian)(jian)速(su)(su)機(ji)(ji)(ji)(ji)，增加(jia)伺服電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)功率是不劃算的(de)。于是，在所需的(de)速(su)(su)度范圍內進行(xing)選擇一(yi)(yi)(yi)個具有(you)可(ke)以(yi)適當減(jian)(jian)(jian)(jian)(jian)速(su)(su)能(neng)力的(de)電(dian)(dian)機(ji)(ji)(ji)(ji)。當電(dian)(dian)機(ji)(ji)(ji)(ji)需要經過(guo)一(yi)(yi)(yi)個過(guo)程(cheng)行(xing)星(xing)減(jian)(jian)(jian)(jian)(jian)速(su)(su)機(ji)(ji)(ji)(ji)時，會(hui)(hui)減(jian)(jian)(jian)(jian)(jian)小(xiao)輸(shu)出軸(zhou)的(de)轉速(su)(su)，其轉矩(ju)會(hui)(hui)增多，行(xing)星(xing)齒輪減(jian)(jian)(jian)(jian)(jian)速(su)(su)機(ji)(ji)(ji)(ji)價格，滿足社(she)會(hui)(hui)工作(zuo)人(ren)員需求。精(jing)密行(xing)星(xing)減(jian)(jian)(jian)(jian)(jian)速(su)(su)機(ji)(ji)(ji)(ji)可(ke)以(yi)通過(guo)兩種法子(zi)聯接(jie)(jie)。一(yi)(yi)(yi)種是握持方(fang)法，也就(jiu)是伺服電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)輸(shu)出軸(zhou)將舒(shu)展到行(xing)星(xing)減(jian)(jian)(jian)(jian)(jian)速(su)(su)機(ji)(ji)(ji)(ji)中并經由過(guo)程(cheng)法蘭聯接(jie)(jie)。行(xing)星(xing)減(jian)(jian)(jian)(jian)(jian)速(su)(su)機(ji)(ji)(ji)(ji)設計(ji)中有(you)這樣一(yi)(yi)(yi)個可(ke)變(bian)形的(de)箍(gu)。操作(zuo)上鎖緊(jin)螺釘時，抱箍(gu)能(neng)牢牢抓住伺服電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)軸(zhou)；另一(yi)(yi)(yi)個通過(guo)外(wai)(wai)部耦合(he)(he)連接(jie)(jie)。使用企業外(wai)(wai)部耦合(he)(he)，因而我們需要伺服電(dian)(dian)源與鍵(jian)槽。

伺(si)服減速(su)(su)機是(shi)伺(si)服減速(su)(su)機齒(chi)輪(lun)(lun)傳動裝置的(de)(de)(de)重(zhong)(zhong)(zhong)量，一(yi)般情(qing)況(kuang)利懿機電齒(chi)輪(lun)(lun)的(de)(de)(de)重(zhong)(zhong)(zhong)量與其材料和熱處理硬度(du)有(you)很(hen)(hen)大(da)關系(xi)。例如在相同功率下(xia)，行星齒(chi)輪(lun)(lun)減速(su)(su)機供應，滲(shen)(shen)碳淬(cui)(cui)火(huo)齒(chi)輪(lun)(lun)的(de)(de)(de)重(zhong)(zhong)(zhong)量將是(shi)調質齒(chi)輪(lun)(lun)重(zhong)(zhong)(zhong)量的(de)(de)(de)1/3左右。所以針對行星齒(chi)輪(lun)(lun)減速(su)(su)機的(de)(de)(de)結構特點和齒(chi)輪(lun)(lun)的(de)(de)(de)載荷性質，應該廣泛采(cai)用硬齒(chi)面齒(chi)輪(lun)(lun)。獲得硬齒(chi)面齒(chi)輪(lun)(lun)的(de)(de)(de)熱處理方法很(hen)(hen)多，如表面淬(cui)(cui)火(huo)，整體(ti)淬(cui)(cui)火(huo)、滲(shen)(shen)碳淬(cui)(cui)火(huo)、滲(shen)(shen)氮(dan)等，應根據行星齒(chi)輪(lun)(lun)減速(su)(su)機的(de)(de)(de)特點考慮(lv)選(xuan)定。
