Claims

[Scope of utility model registration request]

A lubrication collar whose tip is immersed in lubricating oil is installed at the bottom of the bearing fitted on the rotating shaft, and the centrifugal force generated by the rotation of this lubrication collar causes the lubrication oil to be applied in the axial direction to the bearing housing that supports the outer periphery of the bearing. In a bearing device in which oil is supplied to the upper part of the bearing through one or more holes penetrated through the bearing, the lower end of the bear link housing is brought into contact with the bottom of the oil tank with a gasket in between, dividing the oil tank into an inner circumferential side and an outer circumferential side. A bearing device for a vertical rotating electrical machine, characterized in that each oil tank is communicated with each other through a cooling pipe, and oil is supplied to the bearing from the inner oil tank, flows into the outer oil tank, and returns to the inner oil tank through the cooling pipe. .
