Title:
【発明の名称】高速回転軸の流体圧縮膜式ダンパ
Document Type and Number:
Japanese Patent JP2709735
Kind Code:
B2
Abstract:
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.
