Abstract

L'invention concerne un procédé de fabrication d'un élément de machine comme, par exemple, un palier d'arbre (30). Selon l'invention, un procédé de fabrication supplémentaire, comme par exemple la fusion par laser ou le frittage par laser, est utilisé, ce qui permet de fabriquer avantageusement une structure d'élément très complexe en une opération. Des éléments ressort-amortisseur (22) sont fabriqués comme partie intégrante d'une bague extérieure (corps de base 11), ces éléments s'appuyant sur une surface de glissement (25) d'une bague intérieure (corps auxiliaire 31). Un arbre non représenté qui s'appuie par l'intermédiaire du corps de base (11) dans un logement non représenté peut être monté dans le corps auxiliaire. Lors d'un décalage radial de l'arbre par rapport à un axe central (33), les éléments ressort-amortisseur (22) sont déformés provoquant l'effet de ressort. L'effet d'amortissement se produit du fait que les éléments ressort-amortisseur frottent en même temps sur la surface de glissement (25) et qu'il en résulte des pertes par frottement. Sont également concernés des éléments de machine en général, en particulier des paliers d'arbre, qui présentent les propriétés décrites.
