Safety device for rotation of a friction ring axially movably retained in a component mounting arrangement of seal friction ring

Device for security against rotation of a friction ring (4) retained movably axially uncomponente assembly (1) of an arrangement of seal friction ring with a detransmision force (10) ring retentate movable axially in the mounting component and a instalacionde preventing rotation with at least one first driving element (17) which can be brought into engagement in unionpositiva the mounting component and the ring power transmission and least one segundoelemento driver (18) which can be brought into engagement with positive engagement with the ring power transmission andwith the friction ring, wherein the second driving element (18) is axially spaced ring detransmision of force (10) towards the friction ring (4) and can be housed with play in a escotaduraaxial (20) provided in the friction ring (4) and wherein the first element drag is disposed desplazadocircunferencialmente relative to the second drive element, characterized in that - the first driving element (17) is distanced axially mounting component (1) in alanillo direction of force transmission (10) and at the same time can be received in recesses (19, 21) aligned with each other in the ring power transmission (10) and the friction ring (4), and is alojadocon play in axial recesses (19) provided in the transmission ring the force.
