Tilting pad bearing

A tilting pad bearing comprising:

• a plurality of pads including a pad surface slidably supporting an outside surface of a rotor shaft that rotates about an axis;
• a housing formed in an annular shape about the axis, covering the plurality of pads;
• a support portion disposed between the housing and the pads in a radial direction with reference to the axis and supporting the pads swingably with respect to the housing;
• and
• a fluid supply unit configured to supply a fluid from an outside of the housing to the pad surface, wherein
• the pad includes a pad outside surface facing a side opposite to the pad surface in the radial direction,
• the housing includes a housing accommodating recess in which the support portion can be accommodated,
• the support portion includes
• a pivot including a pad support surface in contact with the pad outside surface and a pivot curved surface curved facing and protruding toward a side opposite to the pad support surface in the radial direction,
• a liner disposed between the housing and the pivot and including a first liner surface formed linearly and being in contact with the pivot curved surface, when viewed from a circumferential direction about the axis, and
• a biasing member disposed between the liner and the housing, biasing the liner toward the pivot with respect to the housing, and
• the fluid supply unit includes
• a pad flow channel formed, in the pad, opening on the pad surface,
• a pivot flow channel formed, in the pivot, communicating with the pad flow channel, and
• a housing flow channel formed, in the housing, communicating with the pivot flow channel.
