Abstract
A method for manufacturing a gear includes setting a function f(x) for forming a predetermined tooth profile in a gear, and forming a tooth root and tooth tip using function f(x). Function f(x) is defined so that: a surface shape of the tooth profile from the tooth root to tip has a vertex; a difference between a curvature radius of the surface shape at the tooth root and a radius of an arc or a radius of curvature of a parabola at the root is within a predetermined value; a difference between a curvature radius of the surface shape at the tooth tip and the arc radius or a curvature radius of the parabola at the tip is equal to or greater than a predetermined value; and the surface shape curvature radius at the tip becomes smaller than the arc radius or the parabola curvature radius at the tip.
