輪胎壓路機(jī)簡支式后輪驅(qū)動裝置結(jié)構(gòu)設(shè)計(jì)（II）

摘要：本文對YL25C型輪胎壓路機(jī)后輪驅(qū)動裝置結(jié)構(gòu)設(shè)計(jì)進(jìn)行了闡述。在設(shè)計(jì)過程中，提出3種比較理想的結(jié)構(gòu)方案，并對3種方案進(jìn)行了詳細(xì)的優(yōu)缺點(diǎn)分析，最終選定了簡支式結(jié)構(gòu)方案。本文對液壓馬達(dá)、減速機(jī)、軸承等元件的選型也做了比較詳細(xì)的計(jì)算，對軸的強(qiáng)度進(jìn)行強(qiáng)度計(jì)算與校核、對軸承進(jìn)行壽命計(jì)算分析。運(yùn)用Pro/E對所有的0部件進(jìn)行建模，建模完成后進(jìn)行了干涉分析、運(yùn)動仿真、結(jié)構(gòu)裝拆順序動畫的制作。還通過Pro/e的有限元分析對軸和機(jī)架焊接件進(jìn)行了有限元分析，針對機(jī)架焊接件有限元分析結(jié)果，提出機(jī)架焊接件結(jié)構(gòu)改進(jìn)的方案。完成了主要0件的工程圖繪制和加工工藝過程分析。

The Structural Design about the Simple Supported Rear Drive of Tyre Road Roller

Abstrct: The paper expatiates on the structural design about the rear drive device of tyre road roller. The paper puts forward three structures during the design work, then analyzes the advantages and disadvantages of them in detail, finally chooses a simple supported type structure to use in the design. The paper does much calculation work to choose the right model of the components, such as hydraulic motor, reducer and bearing. The paper checks the strength of the shaft and the service life of the bearing by calculation and analysis. All the parts and components of the device are modeled in using Pro/E. The paper analyzes the interference among parts and components, executes the mechanical motion emulation, and works out an animation about the assembled and unassembled process of the device after the modeling work. The paper uses finite element analysis function in the Pro/E to do finite element analysis work on shaft and supported framework, then makes a structural improvement about the supported framework by using the result of finite element analysis work. The paper also works out drawings and process planning of some major parts and components.

Keyword: tyre roller, the rear drive device, structural design, modeling in Pro/E, finite element analysis (FEA)
