摘要--汽車驅(qū)動(dòng)橋結(jié)構(gòu)設(shè)計(jì)

1、<p><b>　　摘　　要</b></p><p>　　在現(xiàn)代汽車驅(qū)動(dòng)橋上，主減速器的功用是將輸入的轉(zhuǎn)距增大并相應(yīng)降低轉(zhuǎn)速，以及當(dāng)發(fā)動(dòng)機(jī)縱置時(shí)還具有改變轉(zhuǎn)矩旋轉(zhuǎn)方向的作用。單級(jí)主減速器通常由主動(dòng)齒輪和從動(dòng)齒輪組成。在雙級(jí)主減速器中，通常還要加一對(duì)圓柱齒輪或一組行星齒輪。在輪邊減速器中則常采用普通平行軸式布置的斜齒圓柱齒輪傳動(dòng)或行星齒輪傳動(dòng)。主減速器采用的最廣泛的是螺旋錐齒輪和雙曲

2、面齒輪。在某些公共汽車和重型汽車上有時(shí)也選用蝸輪傳動(dòng)。本文首先確定主要部件的結(jié)構(gòu)型式和主要設(shè)計(jì)參數(shù)；然后參考類似驅(qū)動(dòng)橋的結(jié)構(gòu)，確定出總體設(shè)計(jì)方案；最后對(duì)主，從動(dòng)錐齒輪，差速器圓錐行星齒輪，以及對(duì)支承軸承進(jìn)行了壽命校核。本文采用傳統(tǒng)的雙曲面錐齒輪式單級(jí)主減速器作為CA1050的主減速器。</p><p>　　關(guān)鍵詞: CA1050； 主減速器； 雙曲面錐齒輪； 軸承； 行星齒輪</p><p&
