EVALUATION DEVICE OF GEAR PAIR, EVALUATION PROGRAM, AND EVALUATION METHOD OF GEAR PAIR USING THIS

摘要

PROBLEM TO BE SOLVED: To provide an evaluation device of a gear pair capable of calculating the distribution of a load or stress acting on the gear pair in detail over the whole tooth surface. SOLUTION: An arithmetic section 6 calculates a unit distribution load Pn(I, j) as a distribution load on a contact line C-C' at each mesh progression position I when a unit load is charged on mutually meshing tooth pair of the gear pair 100 and mesh rigidity value K0(I) based on each involute tooth surface shape of the tooth pair, calculates shared load f(I) at each mesh progression position I of the tooth pair when a predetermined load Psis charged on the gear pair 100 based on relative tooth surface error S(I, j) of the tooth pair and the mesh rigidity value K0(I), and calculates the real distributed load P(I, j) as the distribution load on the contact line C-C' at each mesh progression position I of the tooth pair when the predetermined load Psis charged on the gear pair 100 based on the unit distribution load Pn(I, j) and the shared load f(I).
