Fixing structure of water-turbine generator set thrust pad

A fixing structure of a water-turbine generator set thrust pad is characterized in that both the inside and the outside of the thrust pad are provided with a groove, the groove on the inside of the thrust pad is fixed by a stop pin, the groove on the outside of the thrust pad is fixed by a limit block, the limit block is connected onto a thrust bearing block through a positioning pin and a fastening part, the groove on the outside of the thrust pad is a circular stepped groove, and the shape of the limit block is matched with that of the groove on the outside of the thrust pad. A trapezoidal spacing stopper between pads in the prior art is omitted, the groove is arranged on the lower portion of the outside of the thrust pad, the stop pin, the limit block and the positioning pin on the inside and the outside of the thrust pad are used for limiting, and oil outlet channels can be enlarged by the aid of chamfer angles on lateral surfaces of the thrust pad. The fixing structure is simple and convenient in process
