Active control tilting pad bearing

The utility model discloses an active control tilting pad bearing which comprises a shell and a plurality of pads, the shell is of a hollow cylindrical structure, a plurality of mounting grooves are formed in the inner wall of the shell in the circumferential direction of the shell, the back of each pad is provided with a pad root embedded in the corresponding mounting groove, and the pads can move in the radial direction of an inner cavity of the shell; a first throttling hole communicated with the mounting groove is formed in the outer wall of the shell, so that when a high-pressure lubricating medium introduced from the outside to the first throttling hole is brought into a gap between the shell and the tile blocks, an outer-layer fluid static pressure film capable of supporting the tile blocks to float in the radial direction of the tile blocks is formed, and the displacement of floating of the tile blocks in the radial direction of the tile blocks is controlled; and through a second throttling hole and a
