Abstract
The present invention relates to a speed reduction apparatus for globoid worm gears. The speed reduction ratio of the engaged worm globoid worm gear and worm wheel is defined as the ratio of the rate of rotation of the globoid worm gear about its axis to the rate of rotation of the worm wheel about its axis. The structure of the present invention speed reduction apparatus is defined by the distance between the axes of rotation of the worm wheel and globoid worm gear and the spacial and speed relationships between the globoid worm gear and the surfaces of the cutting tool employed to generate the worm gear.
