Title:
ジャーナル軸受装置
Document Type and Number:
Japanese Patent JP4121947
Kind Code:
B2
Abstract:
A tilting pad journal bearing, an annular housing for an array of arcuate bearing pads resiliently mounted by spring means which biases the pads against heads of restraining bosses that limit radial displacement and cause the bearing pads to define a shaft space. The pads have associated therewith support pegs ( 60 ) secured to housing or pad at one end and movable relative to the pad or housing at the other, and the spring means comprises stacks of individually deflectable elements mounted between relatively moving pad, housing or peg and pre-loaded by adjusting the effective gap with the pads against the bosses. Relative movement between springs provide friction damping. The restraining bosses may be displaceable together to eliminate the shaft space clearance if the magnetic suspension fails or shows signs of failing.
