Abstract:
1. A coupling for transmitting torque between two shafts approximately aligned on a shaft axis, the coupling having a center axis approximately aligned with the shaft axis, the coupling comprising: a center element formed from an elastomer material, the center element having first and second axial sides; and a clamp ring having an attachment portion adapted to be attached to a shaft, the attachment portion extending axially from each side of the center element along the coupling center axis, the clamp ring having a flange portion embedded within the center element, each clamp ring flange portion having a radially extending part extending away from the clamp ring attachment portion in a direction substantially away from the coupling center axis within the center element such that the clamp ring flange portion radially extending part is perpendicular to the attachment portion and a distal end of the clamp ring flange portion is radially displaced from the clamp ring attachment portion, an amount of the clamp ring flange portion extension in a radial direction away from the coupling center axis and clamp ring attachment portion being selected to provide the coupling with a desired torsional stiffness characteristic.
