基于SolidWorks的二级减速器三维造型设计

摘 要

减速器是一种重要的动力传递装置，但其内部结构复杂，不易准确表达。三维造型设计将减速器的关键部件很清晰地展现出来。本设计以SolidWorks软件为主，并结合AutoCAD、CAXA电子图板等二维绘图软件，设计了一个二级圆柱齿轮减速器，实现了减速器的三维模型，以及由此生成二维工程图的设计思想。通过SolidWorks软件特有的三维设计功能，检查、优化设计方案，实现了减速器的运动仿真，完成了减速器在计算机中的模拟设计。

关键词：减速器，结构设计，三维造型，运动仿真

Abstract

Mechanized production, the gear unit is an important power transmission device but its internal structure is complicated, difficult to accurately express. Three-dimensional design of the key components of the reducer is clearly demonstrated. The design SolidWorks software-based design, combined with AutoCAD, CAXA electronic drawing board, and two-dimensional drawing software, designed a two-stage cylindrical gear reducer, reducer three-dimensional model, and thereby generate a two-dimensional engineering drawings thought. SolidWorks software unique three-dimensional design features, check, optimize, design, motion simulation of the reducer, reducer completed in the computer simulation design. .

Key words: reducer, design of structures, three-dimensional modeling, kinematics simulation
