More Information
Summary:Rotational drive coupling 1, in plastic material, is inserted on and restrained to the end of a driving shaft 2 and engages itself with the end of a driven shaft 3. It comprises a plurality of equal diameter coaxial rings 10-17 suitably spaced each from the other along the nominal rotational axis B-B. Each ring, capable of elastic deformation or bending as to its median plane (P-P), is restrained to the upper and lower one respectively through a first and a second pair of radial and stiff connection spacers. Coupling 1, presents at the same time high values of compressibility, flexibility and rotational stiffness and is particularly suitable for use in driving multicolor ink-ribbon cartridges of serial printers.
