In order to improve the parametric design and manufacture of general cylindrical worm, a parametric design and manufacture software of general cylindrical worm is developed based on the mathematical model of general cylindrical worm, the meshing principle of gear, the structure of worm grinder and the processing technology of worm. Taking the general straight cylindrical worm (ZN-type worm) as an example, the geometric mathematical model of the general straight cylindrical worm is established, according to the spatial position and posture relationship between the worm and the grinding wheel and the gear meshing principle, the mathematical model of the profile of the formed grinding wheel for grinding worm is deduced. Based on Visual C++ 6.0, the software of worm design and manufacture is developed, which includes product management module, worm parameter input module, worm linear transition module, worm linear adjustment module, grinding wheel profile calculation module and processing code generation module. In order to verify the correctness of the developed software, SK6505 NC worm grinder is used to grind the general straight cylindrical worm. The results of measurement after grinding verify the correctness of the software. |
