The tooth profile which is insensitive to the center distance error, without sacrificing the advantages of the W-N gears, is developed. The authors clarified that the relationship between the change in the center distance and the operating pressure angle differs depending on the rate of change of the radius curvature of the tooth profile, and studied and indicated the tooth profile whose radius curvature is suitable for the W-N type gears. Then a formula to calculate the gap between the tooth surfaces of gears which are meshing was derived, and investigated how the gap between the tooth surfaces differs according to the different tooth profile. It is very important to take into account the affects of the expansion of the contact area caused by an elastic deformation on each tooth surface when a force is applied to the surfaces in mesh. Also a study was made to determine the tooth profile which is most ideal and suitable for the W-N gear.
