  • Generic axial roller bearings are well known as axial deep groove ball bearings both in single-row and double-row design and serve to absorb only axial forces substantially.
  • single row axial deep groove ball bearings have only a low axial load capacity with a comparatively large, radial space requirement.
  • double-row axial deep groove ball bearings can be loaded significantly more axially than single-row axial deep groove ball bearings, they are even larger in size than single row axial deep groove ball bearings.
  • Axial cylindrical roller bearings are also known. Although these have a higher load capacity compared to the single-row axial deep groove ball bearings, build in comparison to this radially but also very large. Moreover, the axial cylindrical roller bearings do not permit any tilting, the cylindrical rollers tend to be used for cabinets (skew) and axial cylindrical roller bearings place high demands on the lubrication conditions at a limited speed.
  • the invention is therefore based on the object to present a generic axial rolling bearing, which has a comparatively small radial space requirement.
  • the invention is based on the finding that the use of ball rollers in bearings is possible without appreciable losses in terms of the positive properties of the bearing.

Abstract

La présente invention concerne un roulement axial (1) comprenant au moins une première bague de roulement (10) et au moins une deuxième bague de roulement (11) entre lesquelles une pluralité de corps roulants (13) disposés sur au moins une rangée (12), roulent dans des chemins de roulements (100, 110) en forme de rainures. Selon l'invention, les corps roulants (13) se présentent sous la forme de galets, les galets (13) présentant un axe de rotation (D) qui est approximativement perpendiculaire à l'axe de rotation (R) des bagues de roulement (10, 11). Cette conception permet d'obtenir un encombrement radial significativement réduit par rapport aux conceptions de roulements axiaux classiques.
