Abstract
A tilting pad journal bearing in which the bearing contributes to vibration damping of the supported rotating part without the necessity of substantially preloading the pads against the journal. In a preferred embodiment for a horizontally mounted shaft, the upper, lesser loaded pads are preloaded lightly against the journal by supplying lubricating oil at low pressure to a narrow interstitial space between each such preloaded pad and the bearing casing. In operation, the interstitial space acts as a flow restriction means to prevent a rapid outflow of oil, restricting the pad and shaft from sudden, vibratory movements.
