Abstract
The invention provides a sliding member including a plurality of holes formed on a sliding surface thereof, which sliding surface is adapted to slide on a mating member, at least one of the holes having an enlarged portion in at least a portion between an opening end and a bottom end thereof, the enlarged portion being larger than the opening end on the sliding surface.
Claims8
A sliding member comprising a plurality of holes formed on a sliding surface thereof, which sliding surface is adapted to slide on a mating member, wherein
- at least one of said holes has an enlarged portion in at least a portion between an opening end and a bottom end thereof, the enlarged portion being larger than the opening end on the sliding surface,
- the ratio of B/A is in the range between 1.2 and 4.0. in which the symbol “A” indicates the area of the opening end, and the symbol “B.” indicates the area of the enlarged portion, and
- the average diameter of the holes at the opening ends on the sliding surface is between 1 and 100 μm.
A sliding member comprising a plurality of holes formed on a sliding surface thereof, which sliding surface is adapted to slide on a mating member, wherein
- at least one of said holes has an enlarged portion in at least a portion between an opening end and a bottom end thereof, the enlarged portion being larger than the opening end on the sliding surface,
- the holes comprise at least one hole having the enlarged portion, of which the interior forms a cavity, and at least one hole accommodating a solid lubricant therein, and
- the average diameter of the holes at the opening ends on the sliding surface is between 1 and 100 μm.
A sliding member comprising a plurality of holes formed on a sliding surface thereof, which sliding surface is adapted to slide on a mating member, wherein
- at least one of said holes has an enlarged portion in at least a portion between an opening end and a bottom end thereof, the enlarged portion being larger than the opening end on the sliding surface,
- the ratio of B/A is in the range between 1.2 and 4.0, in which the symbol “A” indicates the area of the opening end, and the symbol “B”indicates the area of the enlarged portion, and
- the depths of the holes at deepest portions thereof are between 5 and 70 μm.
A sliding member comprising a plurality of holes formed on a sliding surface thereof, which sliding surface is adapted to slide on a mating member, wherein
- at least one of said holes has an enlarged portion in at least a portion between an opening end and a bottom end thereof, the enlarged portion being larger than the opening end on the sliding surface,
- the holes comprise at least one hole having an enlarged portion, of which the interior forms a cavity, and at least one hole accommodating a solid lubricant therein, and
- the depths of the holes at deepest portions thereof are between 5 and 70 μm.
A sliding member comprising a plurality of holes formed on a sliding surface thereof, which sliding surface is adapted to slide on a mating member, wherein
- at least one of said holes has an enlarged portion in at least a portion between an opening end and a bottom end thereof, the enlarged portion being larger than the opening end on the sliding surface,
- the average diameter of the holes at opening ends on the sliding surface is between 1 and 100 μm, and
- the depths of the holes at deepest portions thereof are between 5 and 70 μm.
