随着工业技术的发展，摆线齿轮泵的作用愈来愈明显，在一些科技先进国家已经开始广泛应用。本文对摆线齿轮泵做了基本的介绍，阐述了摆线齿轮泵的结构特点以及工作优缺点，并说明了齿轮泵的发展情况以及国内外的发展趋势。对摆线齿轮泵内转子工艺分析及工艺规程的设计做了详尽叙述，同时还设计出了粗铣齿廓工序的专用摆线成形铣刀以及数控精铣齿廓工序的专用夹具。另外，采用CATIA创成式外形设计模块对内转子进行参数化三维建模，用数字加工模块对内转子进行数控模拟加工并生成SINUMERIK 840 D数控程序。
关 键 词：摆线齿轮内转子；工艺；摆线成型铣刀；专用夹具；数控程序。
Abstract
With the development of industrial technology, cycloid gear pump effect is more and more apparent, in some advanced countries already in widespread use of science and technology. The cycloidal gear pump as a basic introduction, elaborated the cycloid gear pump structure characteristics and advantages and disadvantages, and illustrates the gear pump and the development of the domestic and international development trend. The cycloid gear pump rotor process analysis and process design done a detailed description, but also designed the rough milling tooth profile of cycloidal forming process for milling cutter and NC milling tooth profile specialized tongs in the process. In addition, using CATIA generative shape design module to the inner rotor parametric3D modeling, digital processing module to the inner rotor for NC machining simulation and generation of SINUMERIK840 D NC program.
Keywords：The inner rotor of cycloid gear；Technology；Cycloidal forming milling cutter；Special fixture；NC program。
