Definitions

  • the invention relates to a bearing set for an axially closely and accurately leading shaft or the like, such as an impeller or other machine assembly.
  • a bearing set consisting of a four-point bearing - a so-called QJ bearing - and an outboard radial bearing - a so-called NU bearing.
  • Such a bearing combination is for example from the publication WL 00 200/5 DA S.150 of Fa. FAG OEM and Handel AG. Here, this combination is used in a combined reduction and comb gear for shaft bearings.

Abstract

L'invention concerne un jeu de roulement (10) pour un arbre à guider de manière axialement restreinte et précise, une roue ou analogue pour des groupes de machines. L'objectif de cette invention est d'absorber les efforts de contre-pression axiaux relativement peu importants dans un roulement peu coûteux. Ce jeu de roulement (10) est constitué d'un roulement à billes (11) absorbant des efforts de pression axiaux liés au fonctionnement, en particulier d'un roulement à billes à contact oblique, et d'un palier lisse à rebord absorbant des efforts de contre-pression axiaux ou d'un roulement à rouleaux cylindriques (12) conçu en tant que palier d'appui et absorbant des efforts de contre-pression axiaux.
