ABSTRACT
The 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
