Abstract
An increase in the temperature of a sliding bearing can be suppressed, and it is possible to reduce the temperature of the bearing and prevent burning and damage. The bearing is divided in two and composed of a liner and a base metal. The liner is disposed on an inner circumferential side of the bearing, and the base metal is disposed on an outer circumferential side of the bearing. A lower liner of the bearing liner, which is located on a load-receiving side, has a cooling groove formed in an outer circumferential surface thereof and extending along a circumferential direction thereof. A lubricant is cooled in the cooling groove and supplied to reduce the temperature of a shaft-sliding surface of the bearing. The lubricant is supplied to the bearing, increases in temperature due to the cooling and has low viscosity.
