Abstract

Inventia de fata se refera la un variator de turatie de putere constanta, de mare randament, cu corpuri intermediare sferice ale caror axe de rotatie nu sunt materializate. Variatorul de turatie, conform inventiei, foloseste pentru corpul intermediar sferic un sistem de sprijin format din doua perechi de rulmenti ale caror axe sunt montate într-o pozitie perpendiculara una pe alta si situate în planul format de trei puncte de contact dintre corpul intermediar sferic cu cele doua discuri de intrare si un disc de iesire, astfel ca viteza unghiulara de rotatie a corpurilor intermediare sferice se obtine prin compunerea vitezelor unghiulare de rotatie permise de cele doua perechi de rulmenti si de pozitia punctelor de contact, iar un set de rulmenti sunt montati pe un arbore care prezinta la mijlocul sau un alezaj eliptic în care patrunde un suport care are la un capat o forma elipsoidala în sectiune, iar la celalalt capat este tubular si ghideaza într-un canal prelucrat într-un suport fix permitând centrului corpului intermediar sferic sa se deplaseze de-a lungul unei generatoare a discului tronconic de introducere a miscarii.The present invention relates to a high-speed constant speed variator with intermediate spherical bodies whose axis of rotation is not materialized. According to the invention, the speed variator uses for the intermediate spherical body a support system consisting of two pairs of bearings whose axes are mounted in a perpendicular position one on the other and situated in the plane formed by three contact points between the intermediate spherical body the two input discs and an output disc, so that the angular rotation speed of the spherical intermediate bodies is obtained by comparing the rotational angular speeds allowed by the two pairs of bearings and the position of the contact points, and a set of bearings are mounted on a shaft that presents in the middle an elliptical bore in which a support having at one end an ellipsoidal shape in the section and at the other end is tubular and guides in a groove processed in a fixed support allowing the center of the spherical intermediate body to move along a generator of the convex drive plate.
