Claims

[Scope of utility model registration request]

In self-cooling bearing metals that lubricate and cool the bearings of rotating machinery with lubricating oil, a small gap is created between the oil box provided at the bottom of the bearing metal and the outer surface of the oil disk that is directly connected to the rotating shaft. An oil disc chamber with an inner periphery is provided, an oil supply hole is provided below the oil level in the oil box that penetrates the oil box and the oil disc chamber, and the top of the oil disc chamber is connected to the oil supply hole at the top of the bearing metal. A bearing device characterized in that a hole is provided and oil flowing into an oil disk chamber is supplied to a bearing metal by rotation of a rotating shaft.
