ABSTRACT:
A hydrodynamic journal bearing in which a journal rotates within and with clearance relative to a bearing bush, the clearance being filled with a mass of fluid and the load of the journal being supported by the force exerted upon it by the fluid, substantially all of that force being generated by the relative motion of the journal, the fluid, and bush, rather than by means external to the working parts of the bearing. The annular clearance is connected to an undriven fluid accumulator by way of a variable resistance, and that resistance is varied in accordance with journal speed so as to counteract bearing vibration.
