ていることを特徴とする回転機器の軸受装置。 In a bearing device for a rotating device in which a shaft hole of a bearing member and a shaft are rotatably inserted, and a fluid is interposed between the shaft hole and the shaft hole, the inner circumferential surface of the shaft hole or the shaft On one of the outer peripheral surfaces of
A bearing groove is formed in a direction twisted with respect to the axial direction, and a bearing groove in the opposite direction is formed, and a protrusion is formed in the other side, facing the bearing groove with a small gap, In addition, when rotation occurs between the bearing member and the shaft, when the bearing member is floated by a predetermined amount, there is a thrust direction pressure generated at the opposing portion of the bearing groove and the protrusion, and a different twisting direction. A bearing device for a rotating device, characterized in that the pressure in the thrust direction opposite to the above pressure generated in the opposing portion of the other type of bearing groove and the projection is balanced.
