Bearing assembly with multiple squeeze film damper apparatus |
摘要 |
An improved bearing assembly is provided for supporting a rotating shaft. The improvement is comprised of utilizing a resilient support means in combination with a multiple squeeze film damper apparatus. The damper apparatus provides a large damping force to suppress large vibrations and excessive radial shaft deflections in the event of operation with an abnormally high unbalanced shaft. The resilient support provides a soft spring system as a means for establishing and maintaining the critical rotor speed at a low speed condition, for centering the shaft during normal operation, and for allowing radial deflection during operation with an unbalanced shaft.
