Abstract

PURPOSE: To reduce a swelling of the babbit metal in a dovetail grooved part due to a temperature rise and improve a function of forming an oil film, by providing a facing groove in a location at a face-to-fate position to a dovetail groove in the rear metal of a thrust beraing pad used for a vertical shaft water turbine generator or the like.
CONSTITUTION: In a backing metal 8 in the lower part of a dovetail groove 9, a round groove 12 at a face-to-face position to the dovetail groove 9 is provided. In this way, even though thermal expansion is caused in a babbit metal 7, thrust force of an equipment during its operation is always applied to a sliding surface of the babbit metal 7, then the babbit metal 7 is deformed toward the facing groove 12 as shown by a broken line to reduce a swelling of the babbit metal 7 in the dovetail grooved part due to thermal expansion and become a state of the same thermal expansion as for the babbit metal 7 except in the dovetail grooved part 9, thus a good oil film can be formed.
