[5] 编委会编.齿轮便查手册.北京：机械工业出版社，,3学生 张ABSTRACTThe gear mechanism is the most important mechanism transmission of modern mechanical,wide range of applications.It relies on direct contact with the tooth profile to transmit motion and power,with constant transmission ratio,high transmission efficiency,long service life,for a wide range,and high load carrying capacity etc,but there is manufacture and installation of high precision and high cost disadvantages.In this paper, the study says:
1)According to the principle of the gear meshing,grasp the spur gear profiles forming method,and use MATLAB to be computer programming and design gear, get modulus, pressure angle etc. mean standard value involute spur gear of profile data;
2)Familiar with the structure of EDM CNC cutting machine and working principle,learned to master the basic operation of CNC EDM cutting machine, and use of EDM CNC cutting machine machining design of gear;
3)Detection of basic knowledge to understand the kind commonly used measuring instruments and their applications, understand the typical surface detection methods and measuring instruments, measuring instruments to learn the correct choice. For processing out of gear for testing tolerance group.
In this paper, the gear for the object to complete the computer-aided design、 computer-aided processing as well as the accuracy of detection gear for the integration process, combines the knowledge of the discipline, enhance the ability in practice.
Keywords: profiling, line cutting, tolerance group目
