Worm Face gear software.
By Dr. Stepan V. Lunin.
Developed for General Motors and for DAVALL Gear (UK) in 1998.
Development cost 500 hrs.
The Worm Face gear software has been developed to help in design and manufacturing. It generates a 3 dimensional model of the gear set that can be used for CAD modeling, rapid prototyping and CMM inspection.
The program uses Direct Digital Simulation Method. for geometry calculation of the tooth surface. The program simulated manufacturing of the gear by hobbing. The pinion geometry can be generated by cutting or grinding.

Worm Face gears are more reliable against jamming. Most of the time Worm Face gearboxes continue to operate with broken teeth and metal tooth fractions around the mesh. Unlike the planetary gears the worm is less likely get jammed with a metal particle because the worm has a tendency to squeeze the particles out of the mesh.
