定位誤差和調(diào)諧困難是這些系統(tǒng)中常見的題目，它們是由傳動(dòng)的柔性和無效間隙引起的。皮帶、滑輪和變速箱的維護(hù)以及這些易磨損部件的更換都需要付出昂貴的代價(jià)：首先，用戶不得不對(duì)更多的部件進(jìn)行庫(kù)存治理；其次這些附加的部件所造成的系統(tǒng)故障會(huì)增加系統(tǒng)計(jì)劃外停機(jī)時(shí)間，使得機(jī)器的產(chǎn)量出現(xiàn)下降。
直接驅(qū)動(dòng)旋轉(zhuǎn)電機(jī)
可以直接產(chǎn)生驅(qū)動(dòng)作用的旋轉(zhuǎn)電機(jī)本質(zhì)上不過是一種大力矩的永磁電機(jī)，它直接與負(fù)載連接。這種設(shè)計(jì)消除了所有機(jī)械傳動(dòng)部件，如齒輪變速箱、皮帶、滑輪和連軸器。直接驅(qū)動(dòng)旋轉(zhuǎn)系統(tǒng)為設(shè)計(jì)者和使用者帶來了很多好處。

直流電機(jī)勵(lì)磁方式:
他勵(lì)直流電機(jī)
勵(lì)磁繞組與電樞繞組無聯(lián)接關(guān)系，而由其他直流電源對(duì)勵(lì)磁繞組供電的直流電機(jī)稱為他勵(lì)直流電機(jī)，永磁直流電機(jī)也可看作他勵(lì)或自激直流電機(jī)，一般直接稱作勵(lì)磁方式為永磁。
并勵(lì)直流電機(jī)
并勵(lì)直流電機(jī)的勵(lì)磁繞組與電樞繞組相并聯(lián)，作為并勵(lì)發(fā)電機(jī)來說，是電機(jī)本身發(fā)出來的端電壓為勵(lì)磁繞組供電；作為并勵(lì)電動(dòng)機(jī)來說，勵(lì)磁繞組與電樞共用同一電源，從性能上講與他勵(lì)直流電動(dòng)機(jī)相同。
串勵(lì)直流電機(jī)
串勵(lì)直流電機(jī)的勵(lì)磁繞組與電樞繞組串聯(lián)后，再接于直流電源。這種直流電機(jī)的勵(lì)磁電流就是電樞電流。
復(fù)勵(lì)直流電機(jī)
復(fù)勵(lì)直流電機(jī)有并勵(lì)和串勵(lì)兩個(gè)勵(lì)磁繞組。若串勵(lì)繞組產(chǎn)生的磁通勢(shì)與并勵(lì)繞組產(chǎn)生的磁通勢(shì)方向相同稱為積復(fù)勵(lì)。若兩個(gè)磁通勢(shì)方向相反，則稱為差復(fù)勵(lì)。

TIMKEN軸承外圈與輕金屬制的TIMKEN軸承座緊配合時(shí)，采用加熱軸承座的熱裝方法，可以避免配合面受到擦傷。用油箱加熱TIMKEN軸承時(shí)，在距箱底一定距離處應(yīng)有一網(wǎng)柵，或者用鉤子吊著軸承，TIMKEN軸承不能放到箱底上，以防沉雜質(zhì)進(jìn)入TIMKEN軸承內(nèi)或不均勻的加熱，油箱中必須有溫度計(jì)，嚴(yán)格控制油溫不得超過1℃，以防止發(fā)生回火效應(yīng)，使套圈的硬度降低。推力軸承的安裝推力軸承的周全與軸的配合一般為過渡配合，座圈與軸承座孔的配合一般為間隙配合，因此這種TIMKEN軸承較易安裝，雙向推軸承的中軸泉應(yīng)在軸上固定，以防止相對(duì)于軸轉(zhuǎn)動(dòng)。

RTM在葉片出產(chǎn)中的限制身分起首是本錢。RTM的模具設(shè)備很是昂貴。別的，因?yàn)镽TM屬于閉模工藝，很難瞻望樹脂活動(dòng)狀況，輕易產(chǎn)生不合格產(chǎn)品。真空灌注成型工藝真空灌注成型工藝是將纖維加強(qiáng)資料直接鋪放在模具上，在纖維加強(qiáng)資料頂上鋪設(shè)一層剝離層，剝離層凡是是一層很薄的低孔隙率、低滲入率的纖維織物，剝離層上鋪放高滲入介質(zhì)，然后用真空薄膜包覆及密封。真空泵抽氣至負(fù)壓狀況，樹脂經(jīng)由過程進(jìn)膠管進(jìn)入全部別系，經(jīng)由過程導(dǎo)游管指導(dǎo)樹脂活動(dòng)的主標(biāo)的目標(biāo)。
