zl40輪式裝載機驅(qū)動橋設計

1、ZL40輪式裝載機驅(qū)動橋設計摘要本次設計內(nèi)容為ZL40裝載機驅(qū)動橋設計，大致分為主傳動的設計，差速器的設計，最終傳動設計，半軸的設計四大部分。其中主傳動錐齒輪采用35螺旋錐齒輪，這種類型的齒輪的基本參數(shù)和幾何參數(shù)的計算是本次設計的重點所在。將齒輪的幾個基本參數(shù)，如齒數(shù)，模數(shù)，從動齒輪的分度圓直徑等確定以后，用大量的公式可計算出齒輪的所有幾何參數(shù)，進而進行齒輪的受力分析和強度校核。了解了差速器，半軸和最終傳動的結(jié)構(gòu)和工作原理以后，結(jié)合設計

2、要求，合理選擇它們的形式及尺寸。本次設計差速器齒輪選用直齒圓錐齒輪，半軸采用全浮式，最終傳動采用單行星排減速形式。關(guān)鍵詞：關(guān)鍵詞：ZL40，裝載機，驅(qū)動橋AbstractThisdesignwasaZL40loaderdriveaxledesignbroadlydividedintothemaindrivedesignthedifferentialdesignfinaldrivedesigntheaxledesign.Onemaindr
