Abstract
PURPOSE:To enable to enhance the face pressure strength of the titled gear by a method wherein a driving gear of the titled gear is provided with a small diameter while a driven gear is provided with a larger diameter, and the respective top lands are equal to those of symmetric tooth form. CONSTITUTION:In the driving gear 10 and the driven gear 20, the pressure angle of coast-side tooth surfaces 12, 22 of the symmetric tooth form indicated by solid lines is made to be smaller than the pressure angle of drive-side tooth surfaces 11, 21, whereby the asymmetric tooth form is obtained wherein normal-to-axis tooth thicknesses t'S1, tS2 are not changed while normal-to-axis top lands t01, t'02 are increased, as indicated by two-dotted lines. The increment of the normal-to-axis top land of the driving gear 10 is converted into a change of the thickness on the pitch circle of the gear 10, and the converted value is added to the tooth thickness of the driven gear 20. ACcordingly, the driven gear 20 having the normal-to-axis tooth thickness tS2, an outside diameter D02 and a normal-to-axis top land t02 as indicated by broken lines and the driving gear 10 of an outside diameter D01 meshed with the gear 20 are obtained.
