Abstract

PURPOSE: To efficiently cool the bearing metal, by providing a deep blind hole in the bearing metal, forming a groove or wick and the like in said hole for returning the flow of coolant and connecting a heat pipe to the opening end of the blind hole.
CONSTITUTION: In a bearing metal 1 for sliding a supported portion 6 of a rotary main shaft 5, is drilled a deep blind hole 7 in which a groove or wick for performing the retrun flow of coolant of a heat pipe 8 is provided. To the opening end of the blind hole 7 is air-tightly connected the heat pipe 8 the heat radiating end part of which is penetrated through the bottom part of an oil tank 3 and immersed in the leak water W in a leak water tank 9. On the heat pipe 8 between the heat radiating end part and the bottom part of the oil tank 3, a water lift tube 13 is rolled and its lower end is immersed in the leak water W to allow the heat radiating end part to be cooled by the water. While in a water separating plate 10 facing the leak water tank 9, are provided an air suction hole 14 and a blower blade 15 to perform the blowing of air to the water lift tube 13 and permit the evaporation heat absorbed when the cooling water is evaporated to remove the heat of the above described heat radiating end part.
