本课题主要研究的内容是根据减速器设计的原始资料，研究减速器够组成部件（包括齿轮、轴、轴承、上箱体和下箱体）的设计及校核方法。对齿轮减速箱设计进行功能分解，确立齿轮减速器三维参数化设计方法以及齿轮减速器零件（各主要传动件，标准件等）模型库、总装配库的构建方法。并用inventor虚拟软件，进行二级圆锥圆柱齿轮机构的三维建模，对圆锥圆柱减速器的机构的组成，内部传动部件，进行装配干涉分析、应力应变分析、运动仿真，最终生成二维工程图。利用inventor虚拟软件对所设计的产品进行三维建模，装配，运动仿真和工程图的产生等方面进行研究后发现，干涉、应力分析在CAD中是极其重要的内容。从三维开始设计，在现有的软件支持下，这个模型至少有可能表达出设计构思的全部几何参数，整个设计过程可以完全在三维模型上讨论，对设计的辅助就很容易迅速扩大的全过程，设计的全部流程都能使用统一的数据，从三维开始的设计，二维工程图的表达仍然要遵守传统设计的要求。

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.
