Definitions
- Enveloping worm/worm gear transmissions having less than twenty-four teeth have not been commercially used since it was universally believed that it was not possible to build such a transmission due to undercut on the root of the worm gear tooth.
- the enveloping worm/worm gear transmission of the present invention utilizes a worm gear without undercut gear teeth because of a greater enveloping angle for one revolution of the worm thread.
- Figure 1 is a cross-sectional view of a worm/worm gear transmission with the worm gear having three teeth according to the principles of the present invention
- Figure 21 is a perspective view of a worm gear with six teeth with darkened spots illustrated on the surface of the teeth to illustrate the contact surface with the worm in mesh;
- Figure 36 is a cross-sectional view of a spider differential with the sun gear being connected to the first worm gear and the ring gear being connected to the second worm gear of a pair of worm/worm gear transmissions according to the principles of the present invention
