Research and Application on Reverse Engineering of Tooth Surfaces of Hypoid Gear
Reverse engineering, which is an approach for constructing a CAD model from a material solid through dimensional measurement and surface modeling, could be used to structure digitized tooth surfaces of hypoid gear. The reverse engineering of a NURBS tooth surface can be considered as specific number of curve's reverse solution, and the key is the structure of control equations and the selection of boundary conditions in each of reverse processes. According to NURBS theory, the coordinate, normal vector and various kinds of curvatures of all of points in the tooth surface can be solved. Thereupon, the engagement analysis of gear pairs can be achieved before manufacturing, and it is possible to amend manufacturing parameters in time so as to obtain tooth surfaces which meet the needs of function.
