Abstract
A sliding bearing 1 is formed into a cylindrical shape by placing abutting surfaces 11A and 12A of a pair of half-bearings 11 and 12 so as to abut against each other. Two foreign substance discharging grooves 5 and 5′ inclined with respect to an axial direction of the sliding bearing 1 are formed on a sliding surface 3 adjacent to an inner circumferential edge 4 of the abutting surfaces 11A and 12A. When a lubricant is supplied to the sliding surface 3, a foreign substance 6 mixed in the lubricant is trapped by foreign substance discharging grooves 5 and 5′ and then discharged out of the sliding bearing 1 from ends 5A and 5B (5A′ and 5B′) open to end faces 7 and 8.
Claims9
A sliding bearing formed into a cylindrical shape by placing abutting surfaces of an upper half-bearing and a lower half-bearing so as to abut against each other and rotatably support an axis of rotation by a sliding surface made of inner surfaces of both half-bearings,
- wherein a foreign substance discharging groove, an end of which is open to at least one of end faces in an axial direction, is formed on the sliding surface adjacent to an inner circumferential edge of the abutting surface of at least one of the upper and lower half-bearings by being tilted with respect to the axial direction of the sliding bearing, a crush relief made up of a notch is formed on the sliding surface adjacent to the inner circumferential edge and the foreign substance discharging groove is provided within an area in which the crush relief is formed.
A sliding bearing formed into a cylindrical shape by placing abutting surfaces of an upper half-bearing and a lower half-bearing so as to abut against each other and rotatably support an axis of rotation by a sliding surface made of inner surfaces of both half-bearings,
- wherein a foreign substance discharging groove, an end of which is open to at least one of end faces in an axial direction, is formed on the sliding surface adjacent to an inner circumferential edge of the abutting surface of at least one of the upper and lower half-bearings by being tilted with respect to the axial direction of the sliding bearing and the depth of the groove in the foreign substance discharging groove at a central part of the inner circumferential edge is greater than the depth of the groove at the ends open to both end faces.
