Compensating coupling
The invention relates to a compensating coupling for a drive connection of two shafts ( 1, 2 ) with a coupling sleeve ( 4 ) which is made of fiber-reinforced plastic and connects two face-side membranes ( 3 ) and consists of two sleeve sections ( 8 ) which are screwed together with each other via radially outwardly projecting connecting flanges ( 9 ), with the ring-disk-like membranes ( 3 ) forming in the region of their inner circumference a connecting flange ( 5 ) with pass-through holes ( 12 ) for fastening screws ( 14 ), which holes are arranged along a graduated circle, and with the membranes being integrally joined to the coupling sleeve ( 8 ) at their outside circumference. In order to provide advantageous constructional conditions it is proposed that the coupling sleeve ( 8 ) has a smaller outside diameter (d) than the graduated circle diameter (D) reduced by the diameter of the pass-through holes ( 12 ) of the connecting flange ( 5 ), that the sleeve sections ( 8 ) comprise face-side wall disks ( 10 ) which are adjacent to the associated membranes ( 3 ) through a circumferential wall ( 11 ), and that coaxial engagement openings ( 13 ) for fastening screws ( 14 ) are provided in the wall disks ( 10 ) for the pass-through openings ( 12 ) of the connecting flanges ( 5 ).
1 . A compensating coupling for a drive connection of two shafts with a coupling sleeve which is made of fiber-reinforced plastic and connects two face-side membranes and consists of two sleeve sections which are screwed together with each other via radially outwardly projecting connecting flanges, with the ring-disk-like membranes forming in the region of their inner circumference a connecting flange with pass-through holes for fastening screws, which holes are arranged along a graduated circle, and with the membranes being integrally joined to the coupling sleeve at their outside circumference, characterized in that the coupling sleeve ( 8 ) has a smaller outside diameter (d) than the graduated circle diameter (D) reduced by the diameter of the pass-through holes ( 12 ) of the connecting flange ( 5 ), that the sleeve sections ( 8 ) comprise face-side wall disks ( 10 ) which are adjacent to the associated membranes ( 3 ) through a circumferential wall ( 11 ), and that coaxial engagement openings ( 13 ) for fastening screws ( 14 ) are provided in the wall disks ( 10 ) for the pass-through openings ( 12 ) of the connecting flanges ( 5 ).
2 . A compensating coupling according to claim 1 , wherein the fastening screws ( 14 ) rest on the head side on sleeves ( 15 ) which are supported on the side of the connecting flanges ( 5 ) facing the wall disks ( 10 ).
3 . A compensating coupling according to claim 2 , wherein the fastening screws ( 14 ) form a predetermined breaking point for the connecting flange ( 5 ) of at least one membrane ( 3 ) which delimits the transmissible torque.
4 . A compensating coupling according to claim 1 , wherein the face-side wall disks ( 10 ) of the sleeve sections ( 8 ) form a stiffer membrane relative to the membranes to be connected.
