Abstract

PURPOSE: To decrease the temperature of sliding surface of bearing and augment the munimum oil film thickness and the PV limit, by mounting a fan on a shaft and adopting a high effeiciency ventilation passage for cooling air from the fan.
CONSTITUTION: The cooling air sucked by the radial fan 9 mounted on the shaft 1 is supploed through bottom ducts 7-b, 7-a of a beariag stand 7 to a crescent rcess 2-b of the sliding bearing 2 and discharged to another crescent recess 2-b through plual cooling holes 2-c extending in the axial direction. The heat of the bearing is transferred to the cooling air in the cooling holes 2-c, thereby grealy decreasing the temperature of the sliding surface of the bearing. The air heated is discharged to the outside through other bottom ducts 7-a, 7-b of the bearing stand 7.
