Highly elastic shaft coupling particularly for use in connection with elastically supported driving engines
Abstract
Abstract THIS APPLICATION DISCLOSES A HIGHLY ELASTIC SHAFT COUPLING WHEREIN, IN ADDITION TO AT LEAST ONE SLEEVE SPRING ELEMENT COMPRISING AN INNER RING MOUNTED ON ONE OF THE SHAFTS TO BE COUPLED AND HAVING A CONICAL OUTER SURFACE, AN OUTER RING PLACED CONCENTRICALLY OF THE INNER RING AND HAVING A CONICAL INNER SURFACE RADIALLY SPACED FROM SAID OUTER SURFACE, AND A RUBBER-ELASTIC LAYER PLACED BETWEEN SAID CONICAL SURFACES, AT LEAST ONE DISC SPRING ELEMENT IS PROVIDED, THE LATTER COMPRISING A PRIMARY DISC CONNECTED TO SAID OUTER RING, A SECONDARY DISC MOUNTED ON THE SECOND SHAFT, SAID DISCS HAVING AXIALLY OPPOSED AND SPACED SURFACES, AND A RUBBER-ELASTIC LAYER PLACED BETWEEN SAID AXIALLY OPPOSED SURFACES. THIS ARRANGEMENT PROVIDES A COMBINATION OF RADIAL INITIAL COMPRESSION EFFECTED BY THE SLEEVE SPRING ELEMENT WITH AXIAL INITIAL COMPRESSION EFFECTED BY THE DISC SPRING ELEMENT WHEN THE COUPLING IS AXIALLY COMPRESSED.
