Effects of Wear on the Meshing Contact of Worm Gearing


Worm gear contact stresses are the major contributor to worm gear wear and durability failures. In this paper, a combination of loaded tests, coordinate measurements, surface reverse engineering and a special finite element method is employed to study the effect of break-in wear on meshing contact between the mating surfaces of worm gearing parts. Three different wheel tooth geometries are investigated in this paper.
