  • Tubular shaft, particularly for ship propulsion
    Patent number: 5425675
    Abstract: A tubular shaft comprises a torque-transmitting tubular structure compris at least one torque-transmitting shell, which has elastic properties oriented along at least one helical line. To permit the tubular shaft to be used as an effective vibration damper, the shell surrounds a pumping chamber, which is adapted to contain a damping liquid and communicates through at least one constricted passage with a reservoir for damping liquid.

  • Torsionally elastic vibration-damping mechanism
    Patent number: 4262499
    Abstract: A torsionally elastic vibration-damping and/or coupling mechanism has tor-transmitting, radial leaf springs, which at one end are gripped in an outer member and at the other end engage grooves of an inner member. To impart such a damping or coupling device a particularly long life by avoiding unfavorable friction conditions, rolling elements are disposed in the grooves between the leaf springs and the sides of the grooves.
