ROTARY JOINT FOR UNDERWATER OPERATION AND SYSTEM EQUIPPED THEREWITH FOR GENERATING ENERGY FROM WATERPOWER

摘要

The invention relates to a rotary joint (1) for underwater operation, in particular for use in a system (2) for generating energy from waterpower, comprising a first rotationally symmetrical connecting element (13) and a second likewise rotationally symmetrical connecting element (14), which is arranged concentrically with respect to the first connecting element (13) and is rotatable relative thereto. The rotary joint further comprises an annular gap (15) arranged between the two connecting elements (13, 14) and at least one row of rolling bodies (37, 38, 39) rolling along a track on each of the first and the second connecting elements (13, 14). For the sealing of the annular gap (15), a sealing device (21) is provided, which has at least one sealing ring (22) that is fixed on the first connecting element (13) and has a circumferential sealing lip (23) that runs along on a lead-in surface (30), wherein the second connecting element (14) is divided into at least one track ring (40) with at least one track and into a lead-in ring (33) with a stop face (30) for at least one sealing ring (22), wherein the stop ring (33) is removably connected to at least one track ring (40).
