Computerized Design, Generation and Simulation of Meshing of a Spiroid Worm-Gear Drive with a Ground Double Crowned Worm

The authors propose methods of computerized design and analysis of a spiroid worm gear drive with ground worm based on the following considerations: (1) The theoretical thread surface of the hob is generated by a cone surface. (2) The worm surface is crowned is profile and longitudinal directions in comparison with the hob thread surface. (3) The double crowning of the worm enables to localize the bearing contact and obtain a predisigned parabolic function of transmission errors of an assigned level. Computerized design of the worm gear drive enables to discover and avoid singularities of the generated worm face gear surface and pointing of teeth. The meshing and contact of the double crowned worm and the worm face gear is simulated to determine the influence of misalignment on the shift of bearing contact and transmission errors. Computer program of numerical solution is developed and applied. A numerical example that illustrates the developed theory is provided.
