摘 要本文就摆线的基本概念作了介绍，并阐述摆线齿轮泵中，外转子的加工工艺过程、工装设备以及成形拉刀的设计计算。摆线齿轮泵中以内转子为主动轮，外转子为从动轮，在设计中要求外转子精度高，同时考虑到经济成本，在设计加工工艺时，尽量采用既高精度又经济的方式。而且还介绍了在单件生产纲领下，进行摆线齿轮泵外转子曲面磨削的方法。确定了磨削参数及工艺装备。本加工方法具有传动链短，砂轮修磨简单，可稳定的保持加工精度。关键词：摆线齿轮外转子；工艺；结构设计；工装设备；成形拉刀。IAbstractThis article introduced the basic concept of cycloid and cycloid gear pump described, the outer rotor of the machining process, tooling equipment and design calculation of forming broach. Within the rotor cycloidal gear pump for the driving wheel, outer rotor to the driven wheel, the rotor in the design requirements of high precision, taking into account economic costs, in the design process, try to use the high-precision and economical way. But also introduced the program in the single production under the cycloid gear pump outer rotor surface grinding method. Determine the parameters and processes of grinding equipment. This processing method has a short transmission chain, grinding wheel simple, steady and precisionKeywords: cycloidal gear outer rotor; process; structural design; tooling equipment; forming broachII目 录摘 要.......................................................I第1 章 绪论................................................11.1 齿轮泵概述..........................................11.2 齿轮泵发展趋势......................................11.3 外转子设计的基本要求...............................3第2 章 外转子的加工工艺设计...............................42.1 零件的分析..........................................42.1.1 零件的作用.................................42.1.2 零件工艺分析...............................42.2 工艺规程设计......................................
