Large radial bearing with efficient cooling function

The invention provides an efficient cooling large radial bearing, and relates to the technical field of sliding bearings. The efficient cooling large radial bearing comprises a bearing body, the inner wall of the bearing body is provided with a tile back pivot seat, the inner wall of the bearing body is provided with a tilting tile, the outer wall of the tilting tile is provided with a tile back pivot, the spherical surface of the tile back pivot is matched with the tile back pivot seat, and the outer wall of the bearing body is provided with an oil nozzle in a penetrating mode. And a small-end bearing cover is arranged on one side of the bearing body. The oil enters a hole in the tile back pivot seat through the bearing body ring oil groove and enters the back surface of the tilting tile through the hole in the tile back pivot; lubricating oil enters the tile back oil inlet, the transverse oil hole and the inclined oil holes, friction heat of the tile surface is absorbed by cold oil entering in the process,
