Title (EN) ROTARY BRUSH
(FR) BROSSE ROTATIVE
Abstract:
(EN) A rotary radial wire brush made of an annular center disc hub having 32 holes circumferentially spaced apart two radially offset distances from a center about which the brush rotates with a brush wire formed of between 22 and 34 filaments or bristles providing increased material removal rates during a longer useful operating life. A preferred brush has a hub with radially outermost openings larger in size than radially innermost openings causing the brush wire anchored by its twist knot thereto to be more flexible and extend farther radially outwardly than a shorter stiffer more aggressive wire produced by anchoring via a longer twist knot to radially innermost openings. Such a construction produces a rotary brush of the invention with brush wires of alternating flexible and aggressive construction increasing surface finish and material removal rates while having increased brush life.
(FR) L'invention concerne une brosse métallique, radiale et rotative, qui est constituée d'un moyeu de disque central annulaire ayant 32 trous espacés de façon circonférentielle de deux distances radialement décalées par rapport à un centre autour duquel la brosse tourne, un fil métallique comprenant entre 22 et 34 filaments ou brins fournissant de plus grandes vitesses d'enlèvement de matière pendant une durée de vie utile plus longue. Une brosse préférée possède un moyeu ayant des ouvertures radialement extérieures plus grandes que des ouvertures radialement intérieures amenant le fil métallique ancré par son nœud de torsion audit moyeu à être plus flexible et à s'étendre plus loin radialement vers l'extérieur qu'un fil plus court, plus rigide et plus agressif produit par ancrage par l'intermédiaire d'un nœud de torsion plus long aux ouvertures radialement intérieures. Une telle fabrication produit la brosse rotative de l'invention ayant des fils métalliques de construction alternant les fils flexibles et agressifs, augmentant ainsi la finition de surface et les vitesses d'enlèvement de matière tout en ayant une plus longue durée de vie de brosse.
