Title:
SLIDE BEARING
Document Type and Number:
WIPO Patent Application WO/2013/140977
Kind Code:
A1
Abstract:
A slide bearing (2) has a sliding surface (2a) that makes slidable contact with the external peripheral surface of a crank shaft (1) (rotating shaft), and an escape section (4) that recedes radially outward relative to the sliding surface (2a), the escape section (4) being formed in the circumferential direction at both axial end parts on the sliding surface (2a). The escape section (4) is provided with a flat section (4a) formed at an axial end part, and a tapered section (4b) formed so as to gradually descend from the flat section (4a) toward a boundary portion between the escape section (4) and the sliding surface (2a). After forming an eddy or becomes turbulent inside the tapered section (4b), a lubricant circulates along the tapered section (4b), whereby a high pressure region (W) produced by the flow of the lubricant is formed in the position of the flat section (4a). The temperature of the lubricant can be rapidly increased and leakage of the lubricant can be minimized.
