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.......................................................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........................................42.2.1确定毛坯的制造形式.........................42.2.2基面的选择.................................42.2.3制定工艺路线...............................52.2.4机械加工余量，工序尺寸及毛坯尺寸确定......7第3章夹具设计............................................183.1拉胎................................................183.1.1问题的提出.................................183.1.2定位基准的选择.............................183.1.3定位误差分析...............................183.1.4夹紧力......................................183.1.5胎具结构....................................183.2磨胎................................................183.2.1问题的提出.................................183.2.2定位基准的选择.............................183.2.3夹具结构....................................193.3磨头................................................213.4打磨砂轮工具........................................22第4章内曲面成形拉刀设计..................................234.1粗拉刀设计..........................................234.1.1切削部设计.................................234.1.2校准部设计.................................284.1.3其它部分及拉刀总长度.......................294.1.4拉刀强度计算及拉削力的校验................324.2精拉刀设计..........................................334.2.1参数选择....................................334.2.2校核最大拉削力...........................364.2.3拉刀强度校验...............................364.2.4拉刀总长度.................................37结束语.........................................................39致谢.........................................................40参考文献...........
