Grybanova Y. Multicriterion optimization of Novikov cylindrical gearing

The work is devoted to filling of blanks in the decision of an optimality of an initial contour and accuracy of manufacturing of Novikov gearing. Criterion of optimization - qualitative parameters accepted for an estimation of bearing(carrying) abiditions of formation(education) of an oil wedge and susceptibility of transfers to errors of manufacturing and installation. The mathematical model of multicriterion optimization of Novicov gearing was constructed. The new initial contours are providing the gearing 20-25% smaller stress in a root of a tooth and in 2-3 times smaller propensity to errors, than known initial contours. The susceptibility of Novicov gearing to errors is investigated, the techniques of account are developed and the optimal tolerance to manufacturing accuracy of wheels, gearings, hob cutters with new initial contours was researched.
