AI Technical Summary
Technical Problem
Conventional sliding bearings struggle to simultaneously hold lubricating oil and receive loads from rotating shafts effectively.
Method used
The sliding bearing features a sliding surface with a first region containing multiple groove portions for holding lubricating oil and a second region with a different sliding surface shape for receiving loads, both regions being strategically positioned along the rotation direction of the rotating shaft.
Benefits of technology
This design allows for efficient lubrication and effective load reception, ensuring smooth operation and reducing wear on the sliding bearing.

Abstract
This sliding bearing has a sliding surface on which a rotating shaft slides, and allows a lubricating oil to enter a gap between the rotating shaft and the sliding surface. The sliding bearing includes: a first region provided with a plurality of grooves that are recessed in the sliding surface and extend from an end portion in an axial direction of the rotating shaft toward a center portion in the axial direction while being inclined along a rotational direction of the rotating shaft; and a second region having a sliding surface with a shape different from that of the first region. The first region is provided at both ends of the sliding surface in the rotational direction, and the second region is provided between the first regions.
