頁(yè) 共 28 頁(yè) 前言 隨著科學(xué)技術(shù)的迅速發(fā)展，市場(chǎng)競(jìng)爭(zhēng)日趨激烈，在機(jī)械 制造中，運(yùn)輸工業(yè)已成為國(guó)民經(jīng)濟(jì)支柱產(chǎn)業(yè)之一，其在國(guó)民經(jīng)濟(jì)中所占比重和作用越來(lái)越重要，世界各國(guó)經(jīng)濟(jì) 發(fā)展歷程證明了這一點(diǎn)。在產(chǎn)品的技術(shù)水平和內(nèi)在質(zhì)量、性能等方面有了很大進(jìn)步，從注重?cái)?shù)量向注重質(zhì)量和性能方面發(fā)展，產(chǎn)品的技術(shù)水平與國(guó)外先進(jìn)水平的差距在縮小。 η 23= ＝ η 23＝ η 2η 3 . 各軸輸入轉(zhuǎn)矩： 119550nPTd
