基于SW的精密齿轮泵的建模与分析 摘要 齿轮泵是通过一对参数和结构相同的渐开线齿轮的相互滚动啮合，将基体内的低压液体升至能做功的高压油的重要部件。是把发动机的机械能转换成液压能的动力装置。本文在调研的基础上，对齿轮泵的三维模型进行的设计与分析。旨在让大家更加了解与认识齿轮泵。 首先提出了齿轮泵的背景和意义以及国内外发展现状和最新科技，陈述了设计需求，针对本专业——计算机辅助设计做出了介绍。然后在三维设计软件solidworks的基础上进行零部件的三维建模，生成各个零部件的三维模型并进行装配和运动分析。通过此次设计，对齿轮泵的三维建模与分析，能够熟练运用solidworks进行三维建模，并对齿轮泵的结构、工作原理有了更透彻的理解。通过采用三维设计的方法验证了设计的合理性，缩短了产品设计时间，节约了开发成本，提高了产品开发的效率。 关键词：齿轮泵solidworks建模仿真 Abstract Gear pump/wheel pump is a
