EXTRACTION SLEEVE

摘要

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.
