制振軸受。[Claims for Utility Model Registration] 1. In a vibration damping bearing that suppresses vibrations occurring in a rotating shaft of a rotating machine, a cylindrical bearing body serving as a bearing body for the rotating shaft is arranged such that a gap is formed between the inner and outer peripheries of the bearing body. Provided between the rotating shaft and the housing, on the inner circumferential surface of this bearing body, inclined surfaces are spaced along the circumferential direction to generate a wedge pressure between the inner bearing surface of the bearing body and the outer circumferential surface of the rotating shaft. and a communication hole for guiding the dynamic pressure generated by the inclined surface that generates the wedge pressure to the gap between the outer peripheral surface of the cylindrical bearing body and the inner peripheral surface of the housing. 1. A vibration-damping bearing, characterized in that the cylindrical bearing body is provided so as to open in an inclined surface portion of the bearing body, and the cylindrical bearing body is prevented from rotating within a range that does not restrict movement in the radial direction. 2. The communication hole is characterized in that it opens in the inclined surface inside the bearing body in the vicinity of the maximum fluid pressure generated between the rotating shaft and the bearing body by the inclined surface that generates wedge pressure. A vibration damping bearing according to claim 1.
