Abstract
Aiming at the problem of the moving parts of the gear not to realize the dynamic simulation,according to the definition of the standard gear involute in machine design,this research established the mathematical model of the involute for the cylindrical gears profile and the gear profile of the cone.Then the involute is maded for the cylindrical gear's surface and the surface of the worm gear through the method of curve fitting by Solidworks software.And the involute is maded for the sphere surface of cone gear by AutoCAD software.And it carried on the simple comparison to the mathematical model looked for the spot with curve fitting.The results indicate that it is more direct and more accurate to use the method of curve fitting than the mathematical model.It is very practical for the actual design and processing of the 3D gear's simulation.
