  • the basis of the invention is the task of significantly simplifying the design of the rolling bearing while increasing its rigidity in the axial direction due to the fundamental change in the location of the locking elements by making appropriate structural changes in the rolling elements and locking elements.

Abstract

L'invention concerne des roulements à billes que l'on utilise dans divers domaines de l'industrie, notamment dans le génie mécanique lourd. L'invention concerne essentiellement un roulement à billes sans séparateur à galets comprenant un anneau externe, un anneau interne, des rangées de corps de roulement en forme de galets et des éléments de fermeture. Le nombre de galets dans chaque rangée est identique, et la dimension des galets dans chaque rangée diffère en termes de diamètre. La surface externe de l'anneau interne et la surface interne de l'anneau externe possèdent des surfaces cylindriques lisses. Les corps de rotation sont disposés en deux rangées et se présentent sous forme de cylindres ayant des surfaces lisses et des extrémités sphériques. Les éléments de fermeture se présentent sous forme de couvercles d'extrémité de roulements ayant une surface lisse ou comprenant deux gorges coniques radiales pour orienter chaque rangée de galets. Les extrémités des corps de rotation peuvent se présenter sous forme de cônes tronqués ou avoir une autre surface de corps de roulement. Les avantages techniques consistent en une simplification limite de la structure, en une plus grande rigidité, en une fréquence de rotation élevée, en une diminution du bruit, en une forte diminution de l'usure, en un allongement de la durée de vie opérationnelle et en une plus grande capacité de support de charges.
