The present patent invention application concerns a device designed to absorb radial and axial expansion variations during operation of a rotary electric machine. The bushing fits between the bearing and wheel hub to absorb impacts, while enabling a controlled degree of axial and radial movement of the rolling bearing caused by the existing clearance between the bearing and the outer ring of the rolling bearing. La présente demande de brevet d'invention concerne un dispositif conçu pour absorber les variations de dilatation radiale et axiale pendant le fonctionnement d'une machine électrique tournante. La garniture est emboîtée entre le roulement et le moyeu de la roue, de manière à amortir les chocs, et permet en outre, de manière contrôlée, le mouvement radial et axial du roulement compte tenu du jeu présent entre le palier et l'anneau extérieur du roulement. O presente pedido de patente de invenção revela um dispositivo concebido com a finalidade de absorver as variações de dilatação radial e axial, durante o funcionamento da máquina elétrica girante. A bucha é encaixada entre o rolamento e o cubo da roda, de forma a amortecer impactos, porém permitindo a nível controlado o movimento radial e axial do rolamento decorrente da folga existente entre o mancai e o anel externo do rolamento.
