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 is accommodated,
• the support portion includes:
• a pivot including a pad support surface in contact with the pad outside surface and a pivot curved surface 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, 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 and opening on the pad surface,
• a pivot flow channel formed in the pivot and communicating with the pad flow channel, and
• a housing flow channel formed in the housing and communicating with the pivot flow channel.
