Analysis of the correspondence of the obtained involving surfaces of gears designed with CAD systems with the real surfaces
Machines. Technologies. Materials., Vol. 19 (2025), Issue 10, pg(s) 377-378
The paper addresses the problem of designing 3D models of gears, how well the resulting involute profile corresponds to the real one. Very often are used 3d models of gears to produce various gears through 3d prototyping. Some of the most used CAD systems (Solid Works, Solid Edge or Autodesk Inventor) are used to design the 3D models. The comparative analysis made shows the accuracy of modelling the involute profile of the 3D models from different CAD systems compared to the real profile, what are the deviations and how suitable it is to use them for 3D prototyping of gears. Solutions are presented to obtain realistic gear tooth profiles.
