1、齿轮减速箱设计摘要：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
2、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。关键字：三维虚拟设计；三维建模；减速器；Abstract：Themainresearchtopicsarebasedonthedesignoftheoriginaldatareduce
