Tilting pad dynamic pressure bearing

The utility model relates to the technical field of sliding bearings, in particular to a tilting pad dynamic pressure bearing for implementing pressure fluid internal feedback support on a pad back, which specifically comprises a bearing outer ring, a pad block and a mounting component, the sliding surface of the pad block is provided with an oil gathering groove, and the oil gathering groove gathers pressure lubricating fluid on the sliding surface and guides the pressure lubricating fluid into an oil cavity formed in the back of the pad block through oil hole feedback. And a supporting forceon the tile block is formed. A deformation structure is arranged in the middle of the tile block and divides the tile block into two blocks, and the installation assembly exerts radial elastic pressing force on the tile block. When the bearing works, under the action of bearing force of an oil cavity in the back face of the pad, the corresponding block of the pad overcomes the radial elastic pressing force and the main s
