К расчету на изгибную прочность цилиндрических прямозубых колес с нестандартными параметрами ИПК

Abstract

To improve the characteristics of aviation straight-toothed cylindrical gears, non-standard parameters of the initial outline are used: profile angle, radial clearance coefficient, tooth head height coefficient. With the help of these parameters, it is possible to increase the overlap factor to values greater than two. An increase in the height of the tooth head leads to a change in the stiffness and bending strength of the tooth, which requires clarification of reference data when designing the gearbox. The finite element method defines a coefficient that considers the distribution of the load between pairs of teeth and the tooth shape coefficient.
