Title
(EN) LUBRICANT DISCHARGE DEVICE
(FR) DISPOSITIF D'ALIMENTATION EN MATIERE LUBRIFIANTE
Abstract
(EN)
The present invention relates to a lubricant discharge device particularly for discharging lubricant from a bearing housing (1) of an electric motor. The device comprises a tubular element (3) consisting of one or more components (3a, 3b) and arranged at a lubricant discharge opening (2) in the bearing housing (1) of the electric motor, wherein a piston (4) is arranged inside the tubular element (3) and it is connected to an arm section (5). The invention is characterized in that the tubular element (3) comprises a first end (3d) placed substantially at the grease discharge opening (2) of the bearing house (1) in the electric motor, and a second end (3c) that is opposite to the first end and is situated substantially at the outer edge of an end shield of the electric motor, an opening (6) being provided in the casing of the tubular element (3) substantially close to the second end (3c) of the tubular element (3), and a closing means (7) being arranged inside the tubular element (3) at the opening (6) to open and close said opening (6).
(FR)
La présente invention concerne un dispositif d'alimentation en matière lubrifiante conçu en particulier pour libérer de la matière lubrifiante depuis un corps de palier (1) d'un moteur électrique. Ce dispositif comprend un élément tubulaire (3), constitué d'un ou plusieurs composants (3a, 3b) et agencé au niveau d'une ouverture (2) d'alimentation en matière lubrifiante formée dans le corps de palier (1) du moteur électrique. Un piston (4), agencé dans l'élément tubulaire (3), est relié à une section de bras (5). Cette invention se caractérise en ce que l'élément tubulaire (3) comprend une première extrémité (3d), sensiblement placée au niveau de l'ouverture (2) d'alimentation en graisse du corps de palier (1) dans le moteur électrique, et une seconde extrémité (3c) opposée à la première et sensiblement située sur le bord extérieur d'un flasque palier du moteur électrique. Une ouverture (6) est formée dans l'enveloppe de l'élément tubulaire (3), sensiblement près de la seconde extrémité (3c) de l'élément tubulaire (3), et un moyen de fermeture (7), agencé à l'intérieur de l'élément tubulaire (3) au niveau de l'ouverture (6), est conçu pour ouvrir et fermer ladite ouverture (6).
