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。AbstractThisarticleintroducedthebasicconceptofcycloidandcycloidgearpumpdescribed,theouterrotorofthemachiningprocess,toolingequipmentanddesigncalculationofformingbroach.Withintherotorcycloidalgearpumpforthedrivingwheel,outerrotortothedrivenwheel,therotorinthedesignrequirementsofhighprecision,takingintoaccounteconomiccosts,inthedesignprocess,trytousethehigh-precisionandeconomicalway.Butalsointroducedtheprograminthesingleproductionunderthecycloidgearpumpouterrotorsurfacegrindingmethod.Determinetheparametersandprocessesofgrindingequipment.Thisprocessingmethodhasashorttransmissionchain,grindingwheelsimple,steadyandprecisionKeywords:cycloidalgearouterrotor;process;structuraldesign;toolingequipment;formingbroach目录摘要....................................................................第1章绪论.............................................................01.1齿轮泵概述......................................................01.2齿轮泵发展趋势..................................................01.3外转子设计的基本要求............................................2第2章外转子的加工工艺设计..............................................22.1零件的分析......................................................32.1.1零件的作用...............................................32.1.2零件工艺分析.............................................32.2工艺规程设计....................................................32.2.1确定毛坯的制造形式.......................................32.2.2基面的选择...............................................32.2.3制定工艺路线.............................................42.2.4机械加工余量，工序尺寸及毛坯尺寸确定.....................6第3章夹具设计.........................................................163.1拉胎...........................................................163.1.1问题的提出..............................................163.1.2定位基准的选择..........................................163.1.3定位误差分析............................................163.1.4夹紧力..................................................173.1.5胎具结构................................................173.2磨胎...........................................................173.2.1问题的提出..............................................173.2.2定位基准的选择..........................................173.2.3夹具结构................................................173.3磨头...........................................................203.4打磨砂轮工具...................................................20第4章内曲面成形拉刀设计...............................................214.1粗拉刀设计.....................................................214.1.1切削部设计..............................................214.1.2校准部设计..............................................274.1.3其它部分及拉刀总长度....................................284.1.4拉刀强度计算及拉削力的校验..............
