行(xing)星(xing)齒(chi)(chi)(chi)輪減(jian)速機傳(chuan)(chuan)動(dong)(dong)與圓柱(zhu)齒(chi)(chi)(chi)輪減(jian)速機傳(chuan)(chuan)動(dong)(dong)相比較(jiao),它具有許多一(yi)起(qi)的長(chang)處(chu)。它的最明顯(xian)的特點是:在(zai)(zai)傳(chuan)(chuan)遞動(dong)(dong)力時它能夠進(jin)行(xing)功率分流;一(yi)起(qi),其輸(shu)(shu)入軸(zhou)與輸(shu)(shu)出(chu)軸(zhou)具有同軸(zhou)性,即輸(shu)(shu)出(chu)軸(zhou)與輸(shu)(shu)入軸(zhou)均設置在(zai)(zai)同一(yi)主軸(zhou)線(xian)上。所以,行(xing)星(xing)齒(chi)(chi)(chi)輪減(jian)速機傳(chuan)(chuan)動(dong)(dong)現已被人(ren)們用來(lai)替代一(yi)般齒(chi)(chi)(chi)輪傳(chuan)(chuan)動(dong)(dong),而作為(wei)各種機械傳(chuan)(chuan)動(dong)(dong)系(xi)統中的增速器(qi)和變速裝置。
行(xing)(xing)星齒輪(lun)減速(su)(su)機(ji)傳(chuan)動(dong)的(de)(de)(de)主要(yao)特(te)點(dian)如下(xia)。運動(dong)平(ping)穩(wen)(wen)、抗沖(chong)(chong)擊和(he)振蕩(dang)的(de)(de)(de)才能(neng)較(jiao)強因為選(xuan)用(yong)了數(shu)個結構相同(tong)的(de)(de)(de)行(xing)(xing)星輪(lun),均勻地散布于中心輪(lun)的(de)(de)(de)周圍(wei),然后可使行(xing)(xing)星輪(lun)與(yu)(yu)轉臂的(de)(de)(de)性力彼此平(ping)衡。同(tong)軸減速(su)(su)機(ji)一起,也使參加嚙合的(de)(de)(de)齒數(shu)增多,故(gu)行(xing)(xing)星齒輪(lun)傳(chuan)動(dong)的(de)(de)(de)運動(dong)平(ping)穩(wen)(wen),反抗沖(chong)(chong)擊和(he)振蕩(dang)的(de)(de)(de)才能(neng)較(jiao)強,作業較(jiao)牢靠。傳(chuan)動(dong)比較(jiao)大,能(neng)夠(gou)完成(cheng)運動(dong)的(de)(de)(de)組成(cheng)與(yu)(yu)分化只需(xu)恰當挑選(xuan)行(xing)(xing)星齒輪(lun)傳(chuan)動(dong)的(de)(de)(de)類型及配齒計(ji)劃,便能(neng)夠(gou)用(yong)少量幾個齒輪(lun)而取得(de)很大的(de)(de)(de)傳(chuan)動(dong)比。
在僅作為(wei)傳(chuan)遞運動(dong)(dong)的(de)行(xing)(xing)星(xing)(xing)齒(chi)輪減速機(ji)傳(chuan)動(dong)(dong)中(zhong),其(qi)傳(chuan)動(dong)(dong)比可(ke)到達幾千。應(ying)該(gai)指出(chu),行(xing)(xing)星(xing)(xing)齒(chi)輪傳(chuan)動(dong)(dong)在其(qi)傳(chuan)動(dong)(dong)比很大(da)時,依然可(ke)堅持結(jie)構(gou)緊(jin)湊(cou)、質(zhi)量小、體積(ji)小等許多長處。并且,它還能(neng)夠(gou)完成運動(dong)(dong)的(de)組成與分化(hua)以及完成各(ge)種變速的(de)雜亂的(de)運動(dong)(dong)。行(xing)(xing)星(xing)(xing)齒(chi)輪減速機(ji)體積(ji)小、質(zhi)量小,結(jie)構(gou)緊(jin)湊(cou),承載才能(neng)大(da)因(yin)為(wei)行(xing)(xing)星(xing)(xing)齒(chi)輪傳(chuan)動(dong)(dong)具有功率分流和各(ge)中(zhong)心輪構(gou)成共軸(zhou)線式的(de)傳(chuan)動(dong)(dong)以及合(he)理地使用內(nei)嚙合(he)齒(chi)輪副,因(yin)而可(ke)使其(qi)結(jie)構(gou)十分緊(jin)湊(cou)。
再因為在中心(xin)輪(lun)的周圍均(jun)勻地散布著數個行星輪(lun)來一起分(fen)(fen)管載(zai)荷,然后(hou)使得每個齒(chi)輪(lun)所(suo)接受(shou)的負(fu)荷較小(xiao)(xiao),并答應(ying)這些齒(chi)輪(lun)選用較小(xiao)(xiao)的模數。同軸(zhou)減速機此外,在結(jie)構(gou)(gou)上充(chong)分(fen)(fen)利(li)用了內嚙合承載(zai)才能大(da)和(he)內齒(chi)圈自身的可容體積,然后(hou)有利(li)于縮小(xiao)(xiao)其外廓尺(chi)度,使其體積小(xiao)(xiao),質量小(xiao)(xiao),結(jie)構(gou)(gou)十(shi)分(fen)(fen)緊湊(cou),且承載(zai)才能大(da)。
一般(ban)(ban),行(xing)(xing)星齒輪(lun)傳(chuan)動的(de)外廓(kuo)尺(chi)度和(he)質量約為(wei)一般(ban)(ban)齒輪(lun)傳(chuan)動的(de)1/2~1/5?(即在(zai)接受相同的(de)載荷條件下)。行(xing)(xing)星齒輪(lun)減(jian)速機傳(chuan)動功率高因(yin)為(wei)行(xing)(xing)星齒輪(lun)傳(chuan)動結構的(de)對稱性,即它具有數個勻稱散布的(de)行(xing)(xing)星輪(lun),使得(de)效果(guo)于中心(xin)輪(lun)和(he)轉臂軸承(cheng)中的(de)反效果(guo)力能(neng)相互平衡,然后有利于到(dao)達(da)進步傳(chuan)動功率的(de)效果(guo)。在(zai)傳(chuan)動類(lei)型(xing)挑選恰當(dang)、結構安置(zhi)合理的(de)情況下,其功率值可達(da)0.97~0.99.
