Abstract:
A lubricating oil passage portion that constitutes a cooling portion is exposed to the outside from a casing. Lubricating oil having absorbed heat of a thrust bearing portion and a journal bearing portion is cooled in the cooling portion, when the lubricating oil moves from an upper oil chamber to a lower oil chamber while circulating by use of gravity. Thus, the circulating lubricating oil prompts cooling of the heated thrust bearing portion and journal bearing portion. Additionally, the lubricating oil passage portion of the cooling portion is provided integrally with the casing, on the radially outer side of the casing. For this reason, the cooling portion does not require long piping.

Claim (Index 1):
A vertical bearing device comprising:\n a cylindrical thrust collar that rotates together with a rotating shaft member extending in the direction of gravitational force; a base plate that faces the lower end of the thrust collar; a thrust bearing part that is provided in a part where the thrust collar and the base plate face each other in an axial direction of the rotating shaft member, and supports the rotating shaft member in the axial direction; a casing that surrounds the outer peripheral side of the rotating shaft member, is formed into a container shape integrally forming, with the base plate, an oil chamber for storing lubricating oil, and partitions the oil chamber into an upper oil chamber provided on the upper side and a lower oil chamber provided on the lower side in the direction of gravitational force; a journal bearing part that is provided in a part where the casing and the thrust collar face each other in a radial direction of the rotating shaft member, and supports the rotating shaft member in the radial direction; and a cooling part that has a lubricating oil passage part provided integrally with the casing on the radially outer side of the casing, and exposed from the casing to allow passage of the lubricating oil moving from the upper oil chamber to the lower oil chamber, and cools the lubricating oil moving from the upper oil chamber to the lower oil chamber through the lubricating oil passage part by air on the outer peripheral side of the casing.
