  • Bearing with adjustable stiffness
    Patent number: 4850719
    Abstract: A variable stiffness bearing utilizing piezoelectric means for applying a variable preload force to the bearing. The preferred embodiment employs piezoelectric wafers having alternating power and ground connections to the wafers to allow the wafers to distort in direct proportion to the potentials applied. Increased potentials result in greater distortion, more preload force, and a stiffer bearing.
