Title:
BEARING STRUCTURE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2012/128097
Kind Code:
A1
Abstract:
When the temperature of lubricating oil that is at a low temperature is raised, of the outer circumferential sides of a radial slide bearing (30) in a bearing retaining part (13), heat is not supplied from the heating medium in a heating medium flow path (32) at the outer circumferential side of the halved bearing metal (31A) in the bearing retaining body main part (20), which has a large thermal capacity; instead, heat is supplied from the heating medium in the heating medium flow path (32) at the outer circumferential side of the halved bearing metal (31B) in the cap (21), which has a small thermal capacity. Thus, it is possible to suppress the dispersion of the heat supplied from the heating medium in the heating medium flow path (32) into the bearing retaining body main part (20) having a large thermal capacity, and with respect to the heat supplied from the heating medium in the heating medium flow path (32), it is possible to increase the proportion of the heat that is used to raise the temperature of the lubricating oil supplied to the gap between the radial slide bearing (30) and a crank journal (18).
