Abstract

Przedmiotem zgłoszenia jest rolka prostująca prostownicy rolkowej przeznaczona do prostowania zwłaszcza szyn kolejowych lub tramwajowych, charakteryzująca się tym, że powierzchnia robocza rolki prostującej jest na całej swojej długości wklęsła przy czym wielkość wklęsłości jest zmienna począwszy od skrajnych punktów opisanych promieniami stanowiących jednocześnie maksymalną szerokość powierzchni roboczej rolki prostującej, aż do środka osi symetrii rolki prostującej, gdzie zbiegają się linie pochylone względem siebie pod kątem rozwartym w zakresie od 178° do 179,5° i zapewnione jest łagodne ich połączenie za pomocą promienia, w tym obszarze rolka osiąga maksymalną różnicę średnic położonych w punktach skrajnych, najbardziej wypukłych i w osi symetrii rolki prostującej.The subject of the application is a straightening roller of a roller straightener intended for straightening especially railway or tram rails, characterized by the fact that the working surface of the straightening roller is concave along its entire length, with the size of the concavity being variable, starting from the extreme points described by the radii, which are also the maximum width of the roller's working surface. straightening roller, up to the center of the symmetry axis of the straightening roller, where the lines inclined towards each other at an obtuse angle ranging from 178° to 179.5° converge and their smooth connection by means of a radius is ensured, in this area the roller reaches the maximum difference in diameters located in the extreme, most convex points and in the symmetry axis of the straightening roller.
