Title (EN) AUTOMATIC BALANCING DEVICE
(FR) DISPOSITIF A EQUILIBRAGE AUTOMATIQUE
Abstract:
(EN) An auto-balancing device (4) for rotary units or systems, comprising an annular outer race track (11) disposed in a closed, substantially annular housing arranged substantially concentric with and attached to said rotary unit or system, for rotating with said rotary unit or system, and a number of rolling bodies (8) disposed in said housing and freely moveable along said race track (11) for dynamic and/or static contact therewith during rotation of said rotary system, whereby said outer race track is provided in a separate ring (10) of large diameter having a torus-shaped section forming a groove (11) with a curved concave profile facing the centre of the ring, said ring (10) being inserted in a portion of said housing formed as a seat (11) for a seat-surface of the ring and providing sufficient radial rigidity and axial alignment thereto for ascertaining that the circular form of the ring (10) is maintained in spite of forces acting upon it during operation, said torus-shaped groove (11) being concentric with the axis (A) of the rotary system.
(FR) L'invention concerne un dispositif à auto-équilibrage (4) pour organes ou systèmes rotatifs, qui comprend un chemin de roulement extérieur (11) placé dans un logement fermé, sensiblement annulaire et sensiblement concentrique par rapport à l'organe ou au système rotatif auquel il est fixé, et conçu pour tourner en même temps que ledit organe ou système, ainsi que plusieurs corps de roulement (8) placés dans ledit logement et se déplaçant librement le long dudit chemin (11) de sorte qu'ils viennent en contact dynamique ou statique avec celui-ci pendant la rotation dudit système rotatif. Ledit chemin de roulement extérieur se présente sous la forme d'une bague séparée (10) de grand diamètre, présentant une section de forme torique formant une rainure (11) à profil concave en regard du centre de la bague. Ladite bague est insérée dans une partie du logement formant une assise (11) pour la surface à siège de la bague et produit une rigidité radiale et un alignement radial par rapport à celle-ci permet d'assurer le maintien de la forme circulaire de la bague (10) à l'encontre des forces exercées lors du fonctionnement du système, ladite rainure torique (11) étant concentrique par rapport à l'axe (A) du système rotatif.
