Arrangement for coupling fluid supply to rotary part with bellows joint

摘要

The invention relates to a device for coupling the fluid line of a rotatably mounted rotating part through which fluid flows via an axially aligned aperture. At least one end of the rotating part is connected to a fluid supply and/or discharge duct which at one end can be connected to a fluid supply and/or discharge unit and at the other opens out in the region of the aperture of the rotating part. A compensator is provided between the supply and/or discharge region of the fluid and the aperture of the rotating part; the compensator is provided with a sealing section for sealing off the duct, and the end facing the rotating part is connected to the end region of the rotating part so as to be rotationally fixed. According to the invention, the compensator (1) including the sealing section is mounted in a cylindrical sleeve (3) so as to be rotationally fixed; the sleeve is rotatably mounted in an enclosing housing (4) with a certain axial play, and is provided on the side facing the rotating part with a section (12) capable of being connected to the rotating part, and the housing (4), provided with a torque-resisting element (11) and sealed on both sides (7), can be connected on the side facing away from the rotating part with a connection head (17, 25, 26, 32, 33, 35) through which the fluid is fed or removed.
