摘   要
　　　輪邊減速器是傳動(dòng)系中最后一級(jí)減速增扭裝置,采用輪邊減速器可滿足在總傳動(dòng)比相同的條件下,使變速器、傳動(dòng)軸、主減速器、差速器、半軸等部件的載荷減小、尺寸減小以及使驅(qū)動(dòng)橋獲得較大的離地間隙。它被廣泛應(yīng)用于載重貨船、大型客車、越野汽車以及其他一些工程車輛。因此,對(duì)輪邊減速器的研究具有重要的意義。
　　　在本論文研究中，主要展開(kāi)了如下工作：
　　　首先簡(jiǎn)單地介紹了輪邊減速器在國(guó)內(nèi)外的發(fā)展?fàn)顩r和趨勢(shì)，并對(duì)行星式輪邊減速器的特點(diǎn)、傳動(dòng)類型及傳動(dòng)裝置進(jìn)行了闡述和分析。其次根據(jù)輪邊減速器的工作要求，對(duì)輪邊減速器的主要部件進(jìn)行了型號(hào)和材料的選擇。最后根據(jù)給定的設(shè)計(jì)條件，對(duì)輪邊減速器進(jìn)行了傳動(dòng)設(shè)計(jì)計(jì)算，確定了其主要部件的參數(shù)并作了必要的強(qiáng)度校核。

The Design of Three Planets Round Side Reducer on the Drive Bridge of 2.3m3 Wheel Loaders
Abstract
　　　Wheel-side reducer is the last deceleration increase twisted device in the driveline; when the total transmission ratio is same, wheel-side reducer is adopted to reduce the load and size of drive shaft, main gear box, differential, axle, and other parts, and larger off-axle ground clearance of the drive axle. It is widely used in load trucks, large buses, off-road vehicles and other engineering vehicles. Therefore, it is very important for us to research on the wheel-side reducer.
　　　The main work is carried out in this dissertation as follows:
　　　Firstly, the development status and trends of the reducer at home and abroad is briefly introduced, and the characteristics and the transmission type of planetary wheel-side reducer and gears are described and analyzed. Secondly, the selection and material of the main components are chosen based on the working requirements of the wheel-side reducer. Finally, according to the given design conditions, drive design calculations of the wheel-side reducer is conducted, the parameters of its main components is determined and the strength is also checked.
