1、CB-B20液压油泵齿轮与轴的加工工艺设计摘要本设计包含了齿轮和轴的功用特点、热处理、基准的选择、尺寸精度、相互位置精度、粗糙度、齿轮齿形的加工过程及加工工艺,影响齿轮误差的一些因素等基木知识,以设计齿轮与轴的加工工艺过程为思路,通过构思、查资料对齿轮传动进一步了解,进而了解CB—B20液压油泵齿轮与轴的功用特点及特性,从而对齿轮与轴的加工工艺及过程进行研究。设计中由齿轮与轴的功用特性确定他们的材料毛坯,热处理方式,加工端面或圆柱面的先后顺序;包括齿轮与轴在加工过程前准备吋齿轮与轴定位基准的选择;齿轮齿形加工吋确定齿形加工阶段的划分,加工路线、设备,
2、以及影响齿轮误差的一些因素,通过这次设计我学会了用理性思维发现问题、处理问题和解决问题,以达到此次设计的最终目的,这不但捉高了自己的实际操作能力,也迎合了现代化生产的需要。关键词:功用特点齿形加工加工工艺CB-B20hydraulicoilpumpgearandshaftmachiningprocessdesignAbstractThedesignincludesthegearandtheaxisfunctioncharacteristic,theheattreatment,thedatumchoice,thesizeprecision,themut
