Definitions

  • the invention relates to a thrust roller bearing, consisting of a cage containing rolling elements and at least one running disk which merges at a peripheral edge into an axially directed collar which surrounds the cage with play, these components being combined into a structural unit by positive engagement.
  • Such a bearing is known, for example, from US 28 91 828.
  • Such generic bearings in which the disc and cage are held together by retaining lugs, are often only a small radial space available.
  • the cages must therefore be made with thin walls, ie with thin shelves. These ribs, which are narrow in the radial direction, in turn do not offer sufficient hold for the retaining lugs, so that the cage rims must be doubled or provided with a collar in order to prevent the structural unit from falling apart or the retaining lugs on the rolling bodies nudge. In other words, the radially available installation space cannot be optimally used. Summary of the invention
  • the invention is therefore based on the object of avoiding the disadvantages described and of simply designing such a generic bearing in such a way that the radially available installation space can be optimally utilized.
  • this object is achieved according to the characterizing part of the main claim in that the collar is enlarged in its inner diameter at least in a part of the axial extent of the cage, so that an additional free space is created in which the cage is guided.
  • part of the radial wall thickness of the running disk can be used for the installation space of the cage and, on the other hand, there is sufficient overlap between the cage and the holding device of the collar. This means that despite the increased use of the radial installation space for the load-bearing capacity of such an axial bearing, this unit cannot fall apart.
  • the procedure according to claim 2 is expediently such that the cage has on its periphery a projection which points in the radial direction and which engages in the free space.
  • a cage can be easily manufactured either from thin-walled sheet metal or from an plastic by an injection molding process.
  • FIGS 1 and 2 an axial roller bearing according to the invention in partial
  • the axial rolling bearing shown in FIGS. 1 and 2 consists of a cage 2 containing rolling elements 1 and a running disk 3, these three components 1, 2 and 3 being combined to form a structural unit by positive engagement.
  • This edge 5 or the retaining lugs 6 cover the cage 2 in the radial direction, so that a captive unit is given.
  • the axially directed collar 4 on the outer peripheral edge of the running disk 3 encompasses the cage 2 with play and, according to the invention, has an enlarged inner diameter over part of its axial extent, so that a free space 7 is created in which the cage 2 is guided with a projection 8 is.
  • the installation space of the entire axial rolling bearing is expanded by the radial width of the free space 7 without neglecting the required overlap between the cage 2 and the rim 5 or the retaining lug 6.
  • Axial roller bearings which consist of two plane-parallel running disks 3, also fall under the inventive concept, one running disk 3 having the collar 4 with the clearance 7 according to the invention on its outer peripheral edge, while the second running disk 3 has this collar 4 on its inner peripheral edge.

Abstract

Un rebord (4) orienté dans le sens axial d'une barre de roulement (3) d'un palier à roulement axial présente un espace libre (7) additionnel dans lequel est guidée une cage (2). L'espace radial nécessaire au montage d'un palier à roulement axial de ce type peut être élargi d'une largeur de cet espace libre.
