Heat dissipation structure of high-speed sliding bearing

The utility model belongs to the technical field of bearings, and particularly relates to a heat dissipation structure of a high-speed sliding bearing, which comprises a bearing seat and further comprises two groups of oil seals which are arranged on two sides of the bearing seat and are provided with oil outlet edges for leading out lubricating oil; the arc-shaped tile block is arranged in the bearing seat; the heat dissipation mechanism is used for improving the heat dissipation effect of the bearing; the number of the arc-shaped pads is multiple, and the multiple arc-shaped pads are distributed in the bearing seat in an annular array mode. Compared with the prior art, the oil nozzle has the advantages that by arranging the heat dissipation mechanism, the overall temperature of the bearing can be reduced, all the oil spraying holes are integrated on the oil nozzle body by enabling the opening directions of the oil spraying holes to face the oil inlet edges of the arc-shaped pads, the directions of cold oil
