Definitions

  • Rolling bearing having at least a flexible ring.
  • the toroidal portion 13 a extends axially towards the outside of the rolling bearing with the inner axial portion 14a.
  • the two outer half-rings 2a, 2b are positioned with the radial faces 16a, 16b o f the radial portions 12a, 12b in axial contact with one another, approximately in the radial plane of symmetry o f the rolling bearing and the rolling elements 3.
  • the raceways 15 a, 15b o f the outer half-rings 2a, 2b are deformed and better envelop the rolling elements 3.
  • the rolling bearing can take up higher radial lo ads without decreasing bearing life.

Abstract

L'invention porte sur un roulement qui comprend une bague intérieure (1), une bague extérieure (2), au moins une rangée d'éléments roulants (3) disposés entre des pistes (6, 5a, 15b) formées sur les bagues, et un boîtier annulaire (5) à l'intérieur duquel se trouve au moins l'une desdites bagues, ladite bague étant en deux parties (2a, 2b). Chacune des deux parties de ladite bague délimite un espace fermé (21a, 21b) avec le boîtier. Le rapport entre l'épaisseur d'une partie de guidage (13a, 13b) de chacune des deux parties (2a, 2b) délimitant la piste et le diamètre extérieur du roulement est de 0,7 % à 3 % et de préférence de 1,1 % à 1,9 %.
