Publication number: 20160319881Abstract: The present invention concerns a system for coupling a driving machine with a driven machine comprising a driving machine disk comprising first reliefs, and a driven machine disk comprising second reliefs. The second reliefs are arranged relative to the first reliefs to enable the coupling system to form a first configuration allowing axial separation according to the axis of rotation of the two discs and in which the two disks are in contact, the first reliefs being angularly offset relative to the second reliefs, and a second configuration in which the second reliefs engage with the first reliefs and oppose the axial movement of the two disks relative to each other. The shift from the first to the second configuration is made by a rotation of the two disks relative to each other about the axis of rotation.Type: ApplicationFiled: December 9, 2014Publication date: November 3, 2016Applicant: MOTEURS LEROY-SOMERInventor: Patrick VOHLGEMUTH
