Abstract

PURPOSE: To improve the durability of a thrust bearing having a thrust runner split into a plurality of sections, by a method wherein a plurality of bolts for connecting the split sections of the thrust runner are made equal to one another in length.
CONSTITUTION: The thrust runner 2 used in a vertical shaft water turbine is fixed to a shaft 1 ao as to rotate with the latter and in this case the lower surface of the thrust runner 2 is supported by a bearing shoe 3 through an oil film. The thrust runner 2 is split into two halves through a split surface 8 and the split halves are connected to each other with bolts 9 and 10 and nuts 11. The outside bolt 9 is screwed directly into a screwed hole provided in the split sections of the thrust runner and the inside bolt 10 is screwed into a screwed hole 18 through an idle hole 13 provided between the screwed hole 18 for receiving the top end of the bolt 10 and the split surface 8. Thus, by making the bolts 9 and 10 equal to each other in length, it is possible to prevent the bolts, especially the bolt 10, from being damaged due to excessive stress applied thereon.
