1、河南理工大學(xué)萬(wàn)方科技學(xué)院畢業(yè)(論文)摘要提升絞車(chē)作為煤礦等相關(guān)產(chǎn)業(yè)用作升降物料和人員之用，也可作為小型豎井的提升設(shè)備。減速器是用來(lái)匹配轉(zhuǎn)速和傳遞轉(zhuǎn)矩的機(jī)械裝置，通常用運(yùn)輸、化學(xué)工業(yè)、裝卸物質(zhì)和造船工業(yè)中應(yīng)用比較廣泛。在機(jī)械系統(tǒng)中，潤(rùn)滑系統(tǒng)占有很重要的地位，也是一個(gè)非常重要的環(huán)節(jié)。其作用是：提升絞車(chē)工作的時(shí)候，它會(huì)通過(guò)不間斷地向主軸承、減邊器軸承和嚙合齒面壓送潤(rùn)滑油，以達(dá)到軸承與各個(gè)齒輪之間能夠良好的工作。提升絞車(chē)的主軸也是傳動(dòng)的主要部件。主軸在工作時(shí)應(yīng)當(dāng)承受工作過(guò)程中的外負(fù)荷，以至于不發(fā)生殘余變形和過(guò)量的彈性變形，同時(shí)還要保證一定的使用壽命。關(guān)鍵詞：減速器；齒
