49、產(chǎn)生機(jī)械運(yùn)動(dòng)的有用裝置。</p><p>  機(jī)構(gòu)是形成許多機(jī)械裝置的基本幾何結(jié)構(gòu)單元,這些機(jī)械裝置包括自動(dòng)包裝機(jī),打印機(jī),機(jī)械玩具,紡織機(jī)械和其他機(jī)械等。典型的機(jī)構(gòu)要設(shè)計(jì)成使剛體構(gòu)件相對(duì)基準(zhǔn)構(gòu)件產(chǎn)生所希望的運(yùn)動(dòng),機(jī)構(gòu)的運(yùn)動(dòng)設(shè)計(jì)即運(yùn)動(dòng)的綜合,把第一步常常是先設(shè)計(jì)整部機(jī)器。當(dāng)考慮受力時(shí),要提出動(dòng)力學(xué)方面的問(wèn)題,軸承的載荷,應(yīng)力,潤(rùn)滑等類似的問(wèn)題,而較大的問(wèn)題是機(jī)器結(jié)構(gòu)問(wèn)題。</p><p>

50、  齒輪是借助于輪齒成功嚙合來(lái)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)到一傳動(dòng)齒條。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)用中必定是軸向傳動(dòng)。在各種各樣有用的齒輪類型基礎(chǔ)上,輸入軸和輸出軸需要在一直線上或需要互相平行都不受什么限制。由于使用非圓齒輪,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)齒輪齒廓必須服從齒輪嚙合的基本規(guī)律:為了一對(duì)齒能傳遞恒定角速比,他們接觸齒廓的形狀必須是要

51、這樣:公法線通過(guò)兩齒輪中心連線上的固定點(diǎn)。</p><p>  有幾種標(biāo)準(zhǔn)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齒輪。在相交軸的情況下使用直齒錐齒輪或螺旋齒輪。對(duì)于非相交軸和非平行軸齒輪傳動(dòng),交錯(cuò)軸螺旋齒輪,蝸桿蝸輪,端面齒輪,斜齒圓錐齒輪或準(zhǔn)雙曲面齒輪將被選用。對(duì)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(wú)滑動(dòng),齒頂高是輪齒伸出超過(guò)節(jié)圓的高度(也是節(jié)圓

52、和齒頂圓之間在徑向的距離)。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(齒槽S)是沿著節(jié)圓圓弧上相鄰兩齒間的空間距離。而齒側(cè)間隙是在節(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)齒輪都一樣,但一個(gè)必須是右旋斜齒,而另一個(gè)必須是是左旋斜齒,齒的形狀是一漸開(kāi)線螺

53、旋面。如果一張被剪成平行四邊形(矩形)的紙張包圍在齒輪圓柱體上,紙上印粗齒的角刃邊就變成斜線,如果我展開(kāi)這張紙,在斜角刃邊上的每一個(gè)點(diǎn)微發(fā)生一漸開(kāi)曲線。斜齒輪輪齒的初始接觸是一點(diǎn),當(dāng)齒進(jìn)入更多的嚙合時(shí),它就變成線。在斜齒輪中,該線是跨過(guò)齒面的對(duì)角線。它是輪齒逐漸進(jìn)行嚙合并平穩(wěn)地從一個(gè)齒到另一個(gè)齒傳遞運(yùn)動(dòng),那樣就使斜齒輪具有高速重載下平穩(wěn)傳遞運(yùn)動(dòng)的能力。斜齒輪使軸的軸承承受徑向和軸向力,當(dāng)軸向推力變得大了或由于別的原因而產(chǎn)生某些影響時(shí),那

54、就可以使用人字齒輪,雙斜齒輪是與反向的并排地裝在同一軸上的兩個(gè)斜齒輪等效。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)或更多的單向齒斜齒輪被裝在同一軸上時(shí),齒輪的齒向應(yīng)作選擇,以便產(chǎn)生最小的軸向推力。</p><p>  直齒錐齒輪易于設(shè)計(jì)且制造簡(jiǎn)單,如果他們安裝的精密而確定,在運(yùn)轉(zhuǎn)中會(huì)產(chǎn)生良好效果,然而在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

55、證明是切實(shí)可行的,那是和配對(duì)斜齒輪很相似的配對(duì)錐齒輪,當(dāng)在斜齒輪情況下,螺旋錐齒輪比直齒輪能產(chǎn)生平穩(wěn)得多的嚙合作用,因此碰到高速運(yùn)轉(zhuǎn)的場(chǎng)合那時(shí)很有用的,當(dāng)在汽車的各種不同用途中,有一個(gè)帶偏心軸的類似錐齒輪的機(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,這種齒輪之間的輪齒作用是沿著一根直線上產(chǎn)生滾動(dòng)與滑動(dòng)相組合的運(yùn)動(dòng)并和蝸輪蝸桿的輪齒作用有著更多的共同之處。</p><p>

56、;  軸是一轉(zhuǎn)動(dòng)或靜止桿件。通常有圓形橫截面,在軸上安裝像齒輪,皮帶輪,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)變形必須被限制于很小范圍內(nèi)時(shí),其尺寸應(yīng)根據(jù)變形來(lái)確定,然后進(jìn)行應(yīng)力分析。因此,如果軸做得有足夠

57、的剛度以致?lián)锨惶螅敲春蠎?yīng)力符合安全要求那是完全可能的。但決不意味著設(shè)計(jì)者要保證:它們是安全的,軸幾乎總是要進(jìn)行計(jì)算的,知道它們是處在可以接受的允許的極限以內(nèi),因之,設(shè)計(jì)者無(wú)論何時(shí),動(dòng)力傳遞零件,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)于車動(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

58、能安裝,如此瞬變扭矩信號(hào)不可能直接地得到。有些調(diào)查員使用的方法將通過(guò)控制主要傳動(dòng)器參與的位移控制產(chǎn)品扭矩。但位移可能間接地只反射扭矩變動(dòng)。他們對(duì)應(yīng)的關(guān)系是受許多因素的影響的。并且,一旦安裝的位置改變或信號(hào)漂泊,準(zhǔn)確地控制傳送的扭矩價(jià)值將是難的。根據(jù)速度信號(hào)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(hào)的變動(dòng)已知的滑倒的工作。</p><p><b>  2.結(jié)論</b>
