8、t;p>　　齒輪是借助于輪齒成功嚙合來傳遞運(yùn)動(dòng)的機(jī)器零件，齒輪從一根回轉(zhuǎn)軸到另一回轉(zhuǎn)軸傳遞運(yùn)動(dòng)或傳遞運(yùn)動(dòng)到以傳動(dòng)齒輪條，多數(shù)應(yīng)用中都以恒定角速比（或常定扭矩比）而存在，恒定角速比應(yīng)用中必定是軸向轉(zhuǎn)動(dòng)。在各種各樣有用的齒輪類型基礎(chǔ)上，輸入軸和輸出軸在一只想上或需要互相平行都什么限制。由于使用飛圓齒輪，非線性角度比也是很有用的。為了保持恒定的角速度，各個(gè)齒輪廓必須服從齒輪嚙合的基本規(guī)律；為了一對齒輪能傳遞定角速比，他們接觸齒廓的形狀必

9、須是這樣：工法線通過兩齒輪中心線上的固定點(diǎn)。</p><p>　　有幾種標(biāo)注齒輪可供選用。為了在平行軸條件下應(yīng)用，通常使用直齒圓柱齒輪，平行軸斜齒輪或人字齒輪。在相交軸的情況下使用直齒錐齒輪或螺旋齒輪。對于非相交軸和非平行軸齒輪傳動(dòng)，交錯(cuò)軸螺旋齒輪，蝸桿渦輪，端面齒輪，斜齒圓錐齒輪或準(zhǔn)雙曲面齒輪的選用。對于直齒圓柱齒輪，相嚙合齒輪的節(jié)圓是彼此相切的。他們互相滾動(dòng)而無滑動(dòng)，齒頂高是齒輪伸出超過節(jié)圓的高度（也是節(jié)圓和

10、齒頂圓之間經(jīng)向的距離）。頂隙是一個(gè)給定齒的齒根高（在節(jié)圓以下的齒高）大于與它相嚙合的齒輪的齒頂高的量（差值）。齒厚是沿著節(jié)圓圓弧上跨齒的距離，而齒間距是沿著結(jié)緣圓弧上相鄰兩齒間的空間距離。而齒側(cè)間隙是節(jié)圓上的齒槽寬度大于其相嚙合齒輪在節(jié)圓上的齒厚的差值。</p><p>　　斜齒輪用于傳遞平行軸之間的運(yùn)動(dòng)，傾斜角度每個(gè)齒輪度一樣，但一個(gè)必須是右旋斜齒，而另一個(gè)必須是左旋斜齒，齒的形狀是漸開線螺旋面。若果一張被剪成

12、齒輪等效。他們產(chǎn)生相反的軸向推力作用，這樣就消除了軸向推力。當(dāng)兩個(gè)或更多的單向斜齒輪被裝在同一軸上時(shí)，齒輪的齒向應(yīng)做選擇，以便產(chǎn)生最小的軸向推力。</p><p>　　之齒錐齒輪易于設(shè)計(jì)且制造簡單，如果我們暗轉(zhuǎn)的緊密而確定，在運(yùn)轉(zhuǎn)中會產(chǎn)生良好的效果，然而在支直齒圓柱齒輪情況下，在節(jié)線速度較高時(shí)，他們將發(fā)出噪音，在這些情況下，通常設(shè)計(jì)使用螺旋錐齒輪，實(shí)踐證明是切實(shí)可行的，那是和配對斜齒輪很相似的配對錐齒輪，當(dāng)在斜齒

13、輪情況下，螺旋錐齒輪比直齒齒輪能產(chǎn)生平穩(wěn)地多的捏合作用，因此碰到告訴運(yùn)轉(zhuǎn)的場合那是很有用的，當(dāng)在汽車的各種不同用途中，有一個(gè)帶偏心輪的類似錐齒輪的機(jī)構(gòu)，那是常常所希望的，這樣的齒輪機(jī)構(gòu)叫做準(zhǔn)雙曲面齒輪機(jī)構(gòu)，因?yàn)樗麄兊墓?jié)面是雙曲回轉(zhuǎn)面，這種齒輪之間的齒輪作用是沿著一根直線滾動(dòng)與滑動(dòng)組合的運(yùn)動(dòng)并和渦輪蝸桿的齒輪作用有著更多的共同之處。</p><p>　　軸是一轉(zhuǎn)動(dòng)或靜止的桿件，通常有圓形橫截面，在軸上安裝想齒輪，皮

14、帶輪，飛輪，曲柄，鏈輪和其他動(dòng)力傳遞零件。軸能夠承受彎曲，拉伸，壓縮或扭轉(zhuǎn)載荷，這些力相結(jié)合時(shí)，人們期望找到靜強(qiáng)度和疲勞強(qiáng)度作為設(shè)計(jì)的重要依據(jù)，因?yàn)閱胃S可以承受靜應(yīng)力，變應(yīng)力和交變應(yīng)力，所有的應(yīng)力作用都是同時(shí)發(fā)生的。</p><p>　　當(dāng)軸的彎曲或扭轉(zhuǎn)變形鼻血限制與很小范圍時(shí)，其尺寸應(yīng)很據(jù)變形來確定，然后進(jìn)行分析。因此，如果軸做的有做夠的剛度以致?lián)锨惶?，那么和?yīng)力符合安全要求那是完全有可能的。但絕不意味著

15、誰記者要保證：他們是安全的，軸幾乎總是要進(jìn)行計(jì)算的，知道他們是處于可以接受的允許的極限以內(nèi)，因此，設(shè)計(jì)者無論何時(shí)，動(dòng)力的傳遞零件，如齒輪或皮帶輪都應(yīng)該設(shè)置在靠近支撐軸承附近，這就見減低了彎矩，因而減小變形和彎曲應(yīng)力。</p><p>　　根據(jù)關(guān)于動(dòng)力學(xué)的討論，反射和滑倒工作控制與主要傳動(dòng)器傳送的扭矩有關(guān)的變動(dòng)率。然而，扭矩變換裝置在控制系統(tǒng)不可能安裝，如果瞬變扭矩信號不可能直接得到。有些調(diào)查員使用的方法將通過控制

16、主要傳動(dòng)器參與的唯一控制產(chǎn)品扭矩。單位一可能間接的只反射扭矩變動(dòng)。他們對應(yīng)的關(guān)系是受很多因素影響的。并且，一旦安裝位置改變或信號漂泊，準(zhǔn)確地控制傳送的扭矩價(jià)值是很難的。根據(jù)速遞信號的主要傳動(dòng)器自適應(yīng)控制戰(zhàn)略調(diào)整根據(jù)反射的傳送的扭矩和從轉(zhuǎn)動(dòng)的速度信號的變動(dòng)已知的滑倒的工作。</p><p><b>　　結(jié)論</b></p><p>　　依靠速度信號的適應(yīng)性控制策略的關(guān)鍵
