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

Abstract

La présente invention concerne une transmission à double vis sans fin (10,16) qui comprend une vis sans fin (16) de type enveloppant possédant moins de vingt quatre dents, et qui est générée par un filet (12)enveloppant. L'angle d'une révolution de ce filet est supérieur à 15 degrés. Différents profils de cette vis sans fin (16) sont générés par la modification du filet (12) de cette vis.
