<P>PROBLEM TO BE SOLVED: To provide a design program by which a pinion and a tooth flank and/or a bottom of a mating gear do not interfere with each other. <P>SOLUTION: In a design program for a gear meshing with a pinion, a locus of a pinion is determined by a function f(u, θ, Φ) of a parameter u in a pinion facewidth direction, a parameter θ of a pinion pressure angle and a parameter Φ of rotational motion of the pinion, and with respect to a function f(Φ) of coordinates z of a plurality of intersections of the locus of the pinion of an optional cross section of the function f(θ, Φ) and y=y*, the design program has a first step for extracting ranges where three equinoctial points a, b and c in an optional section (a, c) satisfy a<b<c, f(b)<f(a) and f(b)<f(c), a second step for specifying an intermediate point between b and c as d and extracting the minimum value existent section of the function f(Φ) as a section (a, d) and a section (b, c), respectively, when f(b)<f(d), a<b<d, f(b)<f(a) and f(b)<f(d) are satisfied and when f(d)<f(b), b<d<c, f(d)<f(b) and f(d)<f(c) are satisfied and a third step for replacing the minimum value existent section in the second step into a section (a, c), The minimum value of the function f(Φ) is employed as a standard of the coordinate z of the tooth flank and/or bottom of the gear 2 by repeating the second and third steps. <P>COPYRIGHT: (C)2012,JPO&INPIT |
