齒輪齒條(tiao)(tiao)的(de)摩擦系數(shu)_云翔(xiang)機械(xie)(xie)中國齒條(tiao)(tiao)網鏈條(tiao)(tiao)鏈輪廠家(jia)在(zai)(zai)農業(ye)機械(xie)(xie)、建筑機械(xie)(xie)以及簡(jian)易(yi)的(de)機械(xie)(xie)設(she)備中，有一些齒輪傳(chuan)動沒有防塵罩或(huo)機殼，齒輪完全暴露在(zai)(zai)外面，這叫開式齒輪傳(chuan)動。這種傳(chuan)動不(bu)(bu)(bu)(bu)(bu)僅外界(jie)(jie)雜(za)(za)物易(yi)侵入，而且潤(run)滑不(bu)(bu)(bu)(bu)(bu)良(liang)。因此工(gong)作條(tiao)(tiao)件(jian)(jian)(jian)不(bu)(bu)(bu)(bu)(bu)好(hao)，輪齒也(ye)容(rong)易(yi)磨損，故只(zhi)宜用(yong)于(yu)低(di)速傳(chuan)動。當(dang)齒輪傳(chuan)動裝有簡(jian)單(dan)的(de)防護罩，有時還把大齒輪部分浸(jin)入油池中，則稱為半開式齒輪傳(chuan)動。它的(de)工(gong)作條(tiao)(tiao)件(jian)(jian)(jian)雖(sui)有改善，但(dan)仍不(bu)(bu)(bu)(bu)(bu)能坐到嚴密防止(zhi)外界(jie)(jie)雜(za)(za)物侵入，潤(run)滑條(tiao)(tiao)件(jian)(jian)(jian)也(ye)不(bu)(bu)(bu)(bu)(bu)算好(hao)。研磨對于(yu)工(gong)件(jian)(jian)(jian)的(de)附(fu)著力很強(qiang)，磨料分布(bu)高度(du)均(jun)勻，研磨運轉時，研磨劑不(bu)(bu)(bu)(bu)(bu)會甩(shuai)出或(huo)飛濺。自身具有潤(run)滑作用(yong)，研磨時的(de)壓力可達工(gong)件(jian)(jian)(jian)的(de)工(gong)作負荷(he)，被(bei)研工(gong)件(jian)(jian)(jian)表面不(bu)(bu)(bu)(bu)(bu)劃(hua)傷，不(bu)(bu)(bu)(bu)(bu)嵌(qian)砂，不(bu)(bu)(bu)(bu)(bu)膠合，且可在(zai)(zai)很高溫度(du)下使用(yong)。

一些非(fei)凡場所中也(ye)會采用(yong)(yong)變速(su)(su)的滑移齒輪，這種齒輪很少(shao)采用(yong)(yong)，由(you)于(yu)假如(ru)是處于(yu)高(gao)速(su)(su)級的狀況下，滑移變速(su)(su)的齒輪基本就應(ying)付不(bu)外來在設(she)計的時分，普通(tong)設(she)計師(shi)會盡量的把軸的長度給延長一些，由(you)于(yu)假如(ru)軸長過(guo)長的話，那么在滾齒機下面(mian)停(ting)止加(jia)工的難度也(ye)會有所添(tian)加(jia)了。

雙斜齒(chi)(chi)(chi)輪(lun)(lun)（人字齒(chi)(chi)(chi)輪(lun)(lun)）是與反向(xiang)的(de)并(bing)排(pai)地裝在(zai)同(tong)一軸(zhou)上(shang)的(de)兩(liang)(liang)個(ge)(ge)斜齒(chi)(chi)(chi)輪(lun)(lun)等效(xiao)。他們(men)產(chan)生(sheng)相反的(de)軸(zhou)向(xiang)推力(li)作用，這樣就消(xiao)除了軸(zhou)向(xiang)推力(li)。當(dang)兩(liang)(liang)個(ge)(ge)或者跟(gen)多個(ge)(ge)單向(xiang)斜齒(chi)(chi)(chi)輪(lun)(lun)在(zai)同(tong)一軸(zhou)上(shang)時，齒(chi)(chi)(chi)輪(lun)(lun)的(de)齒(chi)(chi)(chi)向(xiang)應作選擇，以便產(chan)生(sheng)小的(de)軸(zhou)向(xiang)推力(li)。　齒(chi)(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)是依靠主動(dong)(dong)齒(chi)(chi)(chi)輪(lun)(lun)依次撥動(dong)(dong)從動(dong)(dong)齒(chi)(chi)(chi)輪(lun)(lun)來(lai)實現(xian)的(de)，其基本要求之一是其瞬時角速(su)度之比必(bi)須保(bao)持不變。　　齒(chi)(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)的(de)分類(lei)：齒(chi)(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)用以傳(chuan)(chuan)遞空(kong)間任意(yi)兩(liang)(liang)軸(zhou)間的(de)運(yun)動(dong)(dong)和(he)動(dong)(dong)力(li)，按照(zhao)兩(liang)(liang)齒(chi)(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)時的(de)相對運(yun)動(dong)(dong)為(wei)平(ping)面(mian)運(yun)動(dong)(dong)或空(kong)間運(yun)動(dong)(dong)，可將其分為(wei)平(ping)面(mian)齒(chi)(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)和(he)空(kong)間齒(chi)(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)兩(liang)(liang)大類(lei)。

效率(lv)是指(zhi)我(wo)們可(ke)以從能(neng)源(yuan)中得到多少有用(yong)的能(neng)量（這里(li)指(zhi)的是電能(neng)）風(feng)力發(fa)電設(she)備(bei)的效率(lv)有多少呢？風(feng)力發(fa)電設(she)備(bei)的效率(lv)與其他大部(bu)分發(fa)電廠(chang)（比如燃煤電廠(chang)）的效率(lv)差不多。

斜齒(chi)(chi)輪的(de)優點嚙(nie)合(he)性能(neng)好：斜齒(chi)(chi)圓柱齒(chi)(chi)輪輪齒(chi)(chi)之間的(de)嚙(nie)合(he)過程是一種過度(du)(du)的(de)過程，輪齒(chi)(chi)上的(de)受力(li)也是逐漸由小(xiao)到(dao)大(da)(da)(da)(da)，再由大(da)(da)(da)(da)到(dao)小(xiao)；斜齒(chi)(chi)輪適用于高速，重載(zai)情況。重合(he)度(du)(du)大(da)(da)(da)(da)：重合(he)度(du)(du)的(de)增大(da)(da)(da)(da)使齒(chi)(chi)輪的(de)承載(zai)能(neng)力(li)提高。從(cong)而(er)延長了(le)齒(chi)(chi)輪的(de)壽命。重合(he)度(du)(du)主要(yao)取決于嚙(nie)合(he)時間，而(er)斜齒(chi)(chi)輪的(de)嚙(nie)合(he)時間長，接觸面積大(da)(da)(da)(da)，使應力(li)減小(xiao)。并使傳動平穩(wen)，且增加(jia)了(le)其經濟(ji)性。
