Computerized design, generation and simulation of meshing and contact of face worm-gear drives Original Research Article

New types of face worm-gear drives are considered. The authors propose methods for localization of bearing contact and reduction of transmission errors achieved by double-crowning of the worm of the drive with respect to the hob, the tool that generates the worm-gear. A computer program for simulation of meshing and contact is provided. Numerical examples based on application of two types of hob thread surface are considered.
