摘 要 ：
本課題主要研究的內(nèi)容是根據(jù)減速器設(shè)計的原始資料，研究減速器夠組成部件（包括齒輪、軸、軸承、上箱體和下箱體）的設(shè)計及校核方法。對齒輪減速箱設(shè)計進行功能分解，確立齒輪減速器三維參數(shù)化設(shè)計方法以及齒輪減速器零件（各主要傳動件，標(biāo)準(zhǔn)件等）模型庫、總裝配庫的構(gòu)建方法。并用inventor虛擬軟件，進行二級圓錐圓柱齒輪機構(gòu)的三維建模，對圓錐圓柱減速器的機構(gòu)的組成，內(nèi)部傳動部件，進行裝配干涉分析、應(yīng)力應(yīng)變分析、運動仿真，最終生成二維工程圖。利用inventor虛擬軟件對所設(shè)計的產(chǎn)品進行三維建模，裝配，運動仿真和工程圖的產(chǎn)生等方面進行研究后發(fā)現(xiàn)，干涉、應(yīng)力分析在CAD中是極其重要的內(nèi)容。從三維開始設(shè)計，在現(xiàn)有的軟件支持下，這個模型至少有可能表達出設(shè)計構(gòu)思的全部幾何參數(shù)，整個設(shè)計過程可以完全在三維模型上討論，對設(shè)計的輔助就很容易迅速擴大的全過程，設(shè)計的全部流程都能使用統(tǒng)一的數(shù)據(jù)，從三維開始的設(shè)計，二維工程圖的表達仍然要遵守傳統(tǒng)設(shè)計的要求。

Abstract：
The main research topics are based on the design of the original data reducer, reducer enough of component parts (including gears, shafts, bearings, the upper casing and lower casing) design and verification method. Of the two conical gear reducer design of functional decomposition, the establishment of three-dimensional parametric gear reducer and gear reducer design parts (the main transmission parts, standard parts, etc.) model library, the total assembly method of constructing the library. And with the inventor of virtual software and database technology, for two conical cylindrical gears three-dimensional modeling of conical reducer cylindrical body composition, the internal transmission parts, and assembly interference analysis, stress and strain analysis, spatial motion analysis, motion simulation, eventually to produce two dimensional drawings. Using inventor of virtual software products designed three-dimensional modeling, assembly, motion simulation and engineering plans and other aspects of the production study found that stress and strain analysis in the CAD is an extremely important element. Only three-dimensional design, be possible to set up the finite element analysis of raw data, and then to part geometry and the optimal shape. Otherwise, the design is the traditional method: even the prototype for many of the bench test for the high cost, cycle length, is the modern market economy can not be tolerated. Starting from the three-dimensional design, in support of existing software, this model may be expressed at least all the geometric parameters of the design concept, the whole design process can be fully discussed in the three-dimensional model, it is easy to design the supporting rapid expansion of the whole process the design of all the processes can use a unified data, starting from the three-dimensional design, the expression of two-dimensional engineering drawings still have to comply with the requirements of traditional design. This is a CAD developed today, tomorrow our computer CAD.






Key words：3D virtual design; three-dimensional modeling; reducer;
