Abstract:
When an annular portion of a thrust collar rotates together with a rotating shaft member, centrifugal force and shear force, or differential pressure caused by difference in flow rate, for example, are generated in lubricating oil in a circulation oil chamber. With this, the lubricating oil in the circulation oil chamber is guided from the inner peripheral side to the outer peripheral side of the annular portion, through a circulation hole penetrating the annular portion. The flow of lubricating oil guided by the circulation hole forms a flow of lubricating oil from a lower oil chamber to an upper oil chamber through the circulation oil chamber. As a result, the lubricating oil stored in the lower oil chamber is circulated to the upper oil chamber through the circulation oil chamber, by rotation of the thrust collar.

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; an annular part that is provided in an annular shape on the lower end of the thrust collar; a base plate that faces the annular part; a thrust bearing part that is provided in a part where the annular part 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 in the direction of gravitational force, a lower oil chamber provided on the lower side in the direction of gravitational force, and a circulation oil chamber provided in a path of the lubricating oil from the lower oil chamber to the upper oil chamber and accommodating the annular part; 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 circulation system part that has a circulation hole penetrating the annular part from the inner peripheral side to the outer peripheral side of the annual part in the radial direction of the rotating shaft member, guides the lubricating oil in the circulation oil chamber from the inner peripheral side to the outer peripheral side of the annular part by rotation of the thrust collar rotating together with the rotating shaft member, and forms a flow of the lubricating oil from the lower oil chamber to the upper oil chamber.
