Patent

CA 2473913

The invention comprises a shaft damper (100) having an inertial mass (30) engaged with an elastomeric member (20) within a shaft bore.(40). The elastomeric member is contained in an annular space between a shaft inner surface (11) and an outer surface (31) of the inertial mass. A profile on the outer surface of the inertial mass enhances a mechanical bond with the elastomeric member. The elastomeric member and the inertial mass are disposed in the shaft in order to damp a bending vibration of the shaft.

L'invention concerne un amortisseur d'arbre (100) présentant une masse inertielle (30) engagée dans un élément élastomère (20) à l'intérieur d'un alésage d'arbre (40). Cet élément élastomère est contenu dans un espace annulaire situé entre une surface intérieure d'arbre (11) et une surface extérieure (31) de la masse inertielle. Un profil de la surface extérieure de la masse inertielle permet d'accentuer une liaison mécanique avec l'élément élastomère. L'élément élastomère et la masse inertielle sont disposés dans l'arbre de sorte à amortir une vibration de courbure de l'arbre.
