16、<p>　　在對(duì)BJ2020S吉普車(chē)后橋的維修中，最主要的就是減速器主、從動(dòng)圓錐齒輪的嚙合印痕及嚙合間隙；差速器半軸齒輪、行星齒輪嚙合間隙和各軸承松緊度的調(diào)整。這是一項(xiàng)既重要又較為困難的工作，因?yàn)楹髽蛑?、從?dòng)圓錐齒輪是在大負(fù)荷、高轉(zhuǎn)速下工作的，而且其所承受的是交變負(fù)荷，如果兩者的嚙合印痕不符合要求，或嚙合間隙不當(dāng)，工作中將會(huì)出現(xiàn)傳動(dòng)不平穩(wěn)和噪音，加速齒面磨損，甚至打壞齒輪，直接影響汽車(chē)使用壽命和各項(xiàng)任務(wù)的完成。同時(shí)，汽車(chē)后

17、橋的結(jié)構(gòu)雖不是很復(fù)雜，但由于主、從動(dòng)圓錐齒輪的體積較大，拆裝費(fèi)時(shí)費(fèi)力，加之一些同志對(duì)齒輪的傳動(dòng)原理不夠熟悉，實(shí)踐機(jī)會(huì)又少，主、從動(dòng)圓錐齒輪嚙合印痕和間隙的檢查調(diào)整及裝配就成了一個(gè)較為復(fù)雜的問(wèn)題。本文根據(jù)幾年來(lái)在教學(xué)和實(shí)際維修工作中的摸索，就BJ2020S吉普車(chē)后橋差速器齒輪和軸承的調(diào)整，主、從動(dòng)圓錐齒輪嚙合印痕和間隙及主動(dòng)圓錐齒輪軸承間隙的調(diào)整和裝配的有關(guān)方</p><p>　　法、步驟談點(diǎn)看法和意見(jiàn)。</

18、p><p>　　一、差速器半軸齒輪與行星齒輪嚙合間隙的調(diào)整</p><p>　　半軸齒輪與行星齒輪嚙合間隙的調(diào)整，是通過(guò)半軸齒輪與差速器殼之間三個(gè)不同厚度(1.0mm、0.5mm、0.2mm)的止推墊片來(lái)調(diào)整的。因?yàn)樾行驱X輪與差速器殼之間的止推墊片是一定的，所以，通過(guò)加、減半軸齒輪的止推墊片(兩半軸齒輪同時(shí)加、減墊片)，使其與行星齒輪的嚙合間隙達(dá)到標(biāo)準(zhǔn)。然后用銷(xiāo)子將行星齒輪軸固定。</p

19、><p>　　二、差速器軸承間隙的調(diào)整</p><p>　　此軸承間隙的調(diào)整是通過(guò)加、減差速器軸承與差速器殼之間四個(gè)不同厚度(0.5mm、0.25mm、0.15ram、0.10ram)的調(diào)整墊片來(lái)調(diào)整的。在調(diào)整前準(zhǔn)備好左、右橋殼之間的密封墊，安裝固定好從動(dòng)圓錐齒輪。主動(dòng)圓錐齒輪先不要安裝，應(yīng)按照規(guī)定的扭矩(40—60N·m)安裝好左、右橋殼，以圓錐主動(dòng)齒輪的位置，用長(zhǎng)金屬棒或大起子轉(zhuǎn)

22、或紅印油)，放進(jìn)差速器總成，按要求裝好左、右橋殼，正、反轉(zhuǎn)動(dòng)主動(dòng)圓錐齒輪，然后分解左、右橋殼，查看從動(dòng)圓錐齒輪齒面上的印痕是否符合要求。如嚙合印痕不符合要求，可視情況通過(guò)向里、向外或向左、向右移動(dòng)主、從動(dòng)圓錐齒輪來(lái)調(diào)整。當(dāng)嚙合印痕偏向齒頂、齒根或齒的大端、小端時(shí)，其調(diào)整口訣為：“頂進(jìn)主，根出主，大進(jìn)從(即從動(dòng)圓錐齒輪移進(jìn)主動(dòng)齒輪)，小出從(即從動(dòng)圓錐齒輪移離主動(dòng)齒輪)”。當(dāng)主、從動(dòng)圓錐齒輪的</p><p>　　

23、嚙合印痕符合標(biāo)準(zhǔn)后，需檢查主、從動(dòng)圓錐齒輪間隙，主動(dòng)圓錐齒輪與從動(dòng)圓錐齒輪的齒側(cè)間隙應(yīng)在主動(dòng)圓錐齒輪法蘭盤(pán)半徑為45mm的圓周上測(cè)量，其位移(弧長(zhǎng))應(yīng)在0.2—0.6mm之間。如不符合標(biāo)準(zhǔn)，可增、減主動(dòng)圓錐齒輪后軸承與主動(dòng)圓錐齒輪之間的墊片或者左、右移動(dòng)差速器軸承調(diào)整墊片來(lái)調(diào)整主、從動(dòng)圓錐齒輪的間隙，因此時(shí)主、從動(dòng)圓錐齒輪的印痕已調(diào)整好，調(diào)整量很小，是不會(huì)破壞主、從動(dòng)圓錐齒輪嚙合印痕的。</p><p>　　五、
