Abstract
A sliding component includes a pair of sliding members being slidable relative to each other on sliding surfaces of the sliding members. In the sliding component, one of the sliding surfaces includes a dimple group in which a plurality of dimples is arranged. Each of the dimple has an opening portion whose shape has a long axis and a short axis orthogonal to the long axis. In the dimple group, the dimples are arranged along a curve having a curvature different from a curvature of a circumference of the one of the sliding surfaces.
Claims10
A sliding component comprising a pair of sliding members being slidable relative to each other on sliding surfaces of the sliding members,
- wherein at least one of the sliding surfaces includes a dimple group in which a plurality of dimples is arranged, each of the plurality of dimples having an opening portion a shape of which has a long axis and a short axis orthogonal to the long axis, and
- in the dimple group, the dimples are arranged so that a curve formed by connecting end points of long axes of the dimples or a curve formed by connecting end points of short axes of the dimples has a curvature different from a curvature of a circumference of the at least one of the sliding surfaces in which the dimple group is included, and
- wherein the curve has a radius and the radius remains constant.
