Radial limiting structure of thrust pad of water-turbine generator set

The utility model provides a radial limiting structure for thrust pads of a water-turbine generator set, which is characterized in that a tooth-shaped limiting piece positioned at the top of a spacer block is arranged between supporting pads; the tooth-shaped limiting piece comprises a limiting block arranged between the supporting pads, a plurality of limiting teeth fixedly arranged on the two sides of the limiting block, a second counter bore formed in the limiting block and corresponding to the first counter bore, and a thrust pad limiting block arranged at the tail end of the limiting block and attached to the side wall, close to the circle center, of the thrust pad. The limiting teeth are embedded into the grooves in the surface of the top of the supporting tile, and the bolt and pin assembly sequentially penetrates through the second counter bores and the first counter bores. The tooth-shaped limiting pieces are arranged between the supporting tiles, radial limiting between the thrust tiles and the supp
