New geometry of face worm gear drives with conical and cylindrical worms: Generation, simulation of meshing, and stress analysis. (English) Zbl 1008.74060
Summary: We propose new geometry of face worm gear drives with conical and cylindrical worms. The generation of the face worm gear is based on the application of a tilted head-cutter (grinding tool) instead of application of a hob applied at present. The generation of a conjugated worm is also based on the application of a tilted head-cutter (grinding tool). The bearing contact of the gear drive is localized and oriented longitudinally. We provide predesigned parabolic function of transmission errors for reduction of noise and vibration. The stress analysis of the gear drive is performed, the contacting model is designed automatically, and the developed theory is illustrated with numerical examples.
