  • Patent number: 12158200
    Abstract: In a gear pair in which a first gear and a second gear having a larger number of teeth than the first gear share a meshing line (L) of teeth that mesh with each other, at least a part of the meshing line (L) includes a region where a pressure angle (a) is not constant, and the pressure angle (?) weakly increases in a section of the meshing line (L) from a pitch point (Pp) to an end point (Pe1) on a tooth-root side of the first gear (G1). This allows both desired properties (for example, strength) and smooth meshing to be achieved, and also allows effective increase in strength of the tooth-root side of the gear having the small number of the teeth (that is, the first gear) subject to a large load and susceptible to damages on the tooth-root side.
