Patent ID: 8002639

Claim:
A torsionally rigid, full steel flexible shaft coupling for torque transmission between shafts having their axes displaced from each other, comprising: a hub having an end surface; a sleeve axially aligned with said hub; a plurality of flanged sleeves and clamping rings; and lamella disks on said flanged sleeves between a ring and a shoulder on the face of said flanged sleeves, said lamella disks being peripherally clamped between said rings and shoulders by threaded nuts and bolts extending through said flanged sleeves, said flanged sleeves having fillet surfaces at their transition to said end surface of said hub, and wherein an axial distance between said shoulders on said flanged sleeves and said end surface of said the hub is related to an outer diameter of the coupling in the ratio of 1:(50 or more), and said fillet surfaces have a coefficient of friction to increase the frictionally transmissible proportion of the torque.
