Контактная прочность зубчатых передач с коническо-цилиндрическими колесами

Abstract

The materials on the novel toothed gearing with spatial spot gearing of the straight evolvent teeth of the bevel-cylindrical gears have been presented. In this gearing the teeth of the pinion were turned by a small angle θ relatively of the gear teeth. In connection with this and taking into account the angle θ, the pinion presents itself bevel whereas the gear remains cylindrical. By that the axex of rotation of the pinion and gear remain parallel each other. The given gearing is characterized by high load capacity on contact stresses. The proposed gearing has been created on the basis of the new theory of contact strength worked out by prof. Popov A.P. To determine the maximum values of contact stresses under consideration gearing spatial contact problem is solved, providing not only finding contact stresses, but also the size of the elliptical contact area, and the minimum values of the rotation angle θ with respect to pinion teeth of the gear teeth.
