Title
(EN) BEARING ELEMENT WITH A SMOOTH CONTINUOUS PROFILE
(FR) ÉLÉMENT DE PALIER À PROFIL CONTINU LISSE
Abstract
(EN)
A bearing element includes an inner surface (54) configured to receive a cylindrical shaft (18). The inner surface (54) includes a smooth profile having a plurality of sections (502). Each section (502) having a taper portion (506) between a first arc-span point (512) and a second arc-span point (514), a constant-radius portion (508) between the second arc-span point (514) and a third arc-span point (516), and a transition portion (510) between the third arc-span point (516) and a fourth arc-span point (518). An inner-surface radius dimension (520) changes from an inner-diameter major dimension to an inner-diameter minor dimension at the taper portion (506) and back at the transition portion.

Un élément de palier comprend une surface interne (54) configurée pour recevoir un arbre cylindrique (18). La surface interne (54) comprend un profil lisse ayant une pluralité de sections (502). Chaque section (502) comporte une partie effilée (506) entre un premier point d’étendue d’arc (512) et un deuxième point d’étendue d’arc (514), une partie à rayon constant (508) entre le deuxième point d’étendue d’arc (514) et un troisième point d’étendue d’arc (516), et une partie de transition (510) entre le troisième point d’étendue d’arc (516) et un quatrième point d’étendue d’arc (518). Une dimension de rayon de surface interne (520) change d’une dimension majeure de diamètre interne à une dimension mineure de diamètre interne au niveau de la partie effilée 506 et de retour au niveau de la partie de transition.
