ABSTRACT:
A tilting pad type bearing device prevents the temperature elevation of the tilting pads, and heat sticking, and generation of unstable vibration concomitant with temperature elevation, and effectively utilizes lubricant oil to ensure a stable high performance. The tilting pad type bearing device is used for supporting a shaft through a plurality of tilting pads (2a to 2e) angularly movably supported at pins (3a to 3e) fixed to an inner circumference of a housing. An outer circumferential surface of each of the tilting pads (2a to 2e) and/or an inner circumferential surface of said housing (6) confronting the outer circumferential surface has a plurality of grooves (14a, 14b) in the circumferential direction, and a plurality of small diameter orifices (11a, 11b) for jetting lubricant oil directly to the grooves or the outer circumferential surface are arranged in said housing (6) or in oil supply pieces (4a to 4c) disposed between the adjacent tilting pads (2a to 2 e) in the circumferential direction.
