Title (EN) EXTRACTION SLEEVE
(FR) DOUILLE D'EXTRACTION
Abstract: front page image
(EN) The subject of the invention is an extraction sleeve (10) for extracting two rotationally symmetrical parts that are joined together by hooping, said sleeve being characterized in that it comprises: a head (11) having a conical part; a cylindrical body (12), the internal part of the cylindrical body (12) having a screw thread suitable for the screwing of an extraction screw; said conical part of the head (11) of the extraction sleeve (10) forming a friction means suitable for coming into contact with one of the rotationally symmetrical parts, said friction means being designed so as to determine a limit slipping torque greater than the friction torque generated at the screw thread of the sleeve by the screwing of the extraction screw.
(FR) L'invention a pour objet une douille d'extraction (10) pour l'extraction de deux pièces de révolution assemblées par frettage, ladite douille étant caractérisée en ce qu'elle comporte : une tête (11) présentant une partie conique; un corps (12) de forme cylindrique, la partie interne du corps (12) cylindrique présentant un pas de vis adapté pour permettre le vissage d'une vis d'extraction; ladite partie conique de la tête (11) de la douille d'extraction (10) formant un moyen de frottement adapté pour venir au contact de l'une des pièces de révolution, ledit moyen de frottement étant dimensionné de manière à déterminer un couple limite de glissement supérieur au couple de frottement généré au niveau du pas de vis de la douille par le vissage de la vis d'extraction.
