Abstract

L'invention concerne le domaine des machines-outils. Une broche rotative pour machine à rectifier comprend un palier à roulement à billes avant Il, 12 fixement monté dans un bâti 3 et un palier à roulement à billes arrière 13, 14 monté dans un porte-roulement 18, des différences de dilatation thermique dans le sens axial nécessitant une certaine liberté de déplacement axial d'un palier par rapport au bâti. A cet effet, le porte-roulement 8 est rattaché au bâti par l'intermédiaire d'une ou plusieurs membranes 20, 21 dont la flexibilité fournit ladite la dite liberté de déplacement axial. L'invention s'applique avantageusement aux broches portant des meules de machine à rectifier les intérieurs et tournant à des vitesses très élevées.
