High-speed sliding fixing tile thrust bearing

The utility model discloses a high-speed sliding fixing tile thrust bearing, which comprises a thrust bearing body and a front radical bearing, wherein the thrust bearing body and the front radical bearing are arranged in a same bearing body to form a joint bearing; the thrust bearing body is composed of a working surface thrust tile and a non-working surface thrust tile; the thrust tile is composed of ten tile blocks, an oil return groove and an annular chamber; the ten tile blocks are evenly distributed along the circumference; each tile block is in a fan shape which is formed by combining an inclined plane and a support plane; and each inclined plane inclines towards two directions. The high-speed sliding fixing tile thrust bearing disclosed by the utility model is suitable for a feed-water pump turbine, and has the characteristic of linear support; and the temperature of the thrust tiles in the bearing can meet the requirements in the normal running process of the feed-water pump turbine by optimizing the fan shape combined by the inclined planes and the support planes of the thrust tiles, adjusting the oil inflow ratio of the working surface thrust tile and the non-working surface thrust tile, changing the size of oil outlets of the thrust tiles, and the like.
