Abstract:
A cooling portion has an air inlet into which cooling air flows and is positioned in a preset range. When a distance from the upper to lower ends of an oil chamber in the axial direction of a rotating shaft member is h, and the shortest distance between an outer peripheral face of a casing and an inner peripheral face of a cover is a, the preset range is set in the following manner. Specifically, the preset range is set between ¼h upward and 5/4h downward relative to the upper end of the oil chamber as a reference point, in the axial direction of the rotating shaft member. Additionally, the preset range is set between the outer peripheral face of the casing and relative to the outer peripheral face of the casing as a reference point, in the radial direction of the rotating shaft member.

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 an 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; a cooling part that is provided integrally with the casing on the radially outer side of the casing, has a lubricating oil passage part exposed from the casing and allowing 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; and a cover that is provided outside the casing in the radial direction of the rotating shaft member, and forms, with the casing, a space through which air flows, wherein: the cooling part has an air inlet into which cooling air flows, and is positioned in a preset range; and when a distance from the upper to lower ends of the oil chamber in the axial direction of the rotating shaft member is h, and the shortest distance between an outer peripheral face of the casing and an inner peripheral face of the cover is a, the preset range is\n set between \u00bch upward and 5/4h downward relative to the upper end of the oil chamber as a reference point, in the axial direction of the rotating shaft member, and \n set between the outer peripheral face of the casing and  2 a  relative to the outer peripheral face of the casing as a reference point, in the radial direction of the rotating shaft member.
