摘要： A rotary machine 10 includes a rotor shaft 40 and a support system 63 for the shaft. The support system includes a spring 68 and viscous damper 70. Apparatus for removing oil from the damper at preselected rotor speeds is provided and in one embodiment permits operating the engine over a rotor speed range which avoids critical speeds.

摘要： The characteristics of a viscous damper for high speed bearings of a gas turbine engine are changed by providing recirculation grooves at the outer edge of the inner diameter of the damper annular wall. Reduced shaft excursions are evidenced without affecting the size, oil flow and stiffness characteristic of the damper.

摘要： A magnetic bearing assembly is disclosed which provides for correction of shaft deflection, or "bowing", during rotation of the shaft. The assembly comprises two stator rings in spaced relation to each other, and each stator ring comprises a plurality of stator sections which are independently activated. When the shaft "bows", sensors detect the deflection and independently activate the various stator sections producing a force couple which acts on the rotor to produce a bending moment in the shaft which tends to counteract the "bowing".

摘要： A friction damper is mounted in series with a viscous damper to accommodate the normal magnitude vibration and the higher magnitude vibration occasioned from a larger imbalance of a jet engine rotor manifested by a bowed rotor and including a loading spring to allow the recentering of said friction damper when the higher magnitude vibrations subside.

摘要： The critical speed of a bearing supported rotating shaft is changed or controlled by dimensioning the oil squeeze film damper so that the volumen of oil is selected to produce a spring rate that when added to the mechanical spring rate will attain the overall spring rate of the system. The spring rate of the oil becomes effective when the volume is at a predetermined value which is at a level higher than heretofore known oil squeeze film dampers.
