    摘要： A sliding member includes a back metal layer and a sliding layer on the back metal layer. The sliding layer includes a synthetic resin matrix and graphite particles dispersed in the matrix in a volume ratio of 5-50% of that of the sliding layer. The graphite particles are composed of spheroidal and flake-like particles. The flake-like particles have a volume ratio of 10-40% of total graphite particles. The spheroidal particles have a cross-sectional structure with a plurality of AB planes of a graphite crystal laminated along a curved particle surface, from the surface toward a center direction. The flake-like graphite particles have a cross-sectional structure with the plurality of AB planes laminated in a thickness direction of the thin plate shape. The spheroidal particles have an average particle size of 3-50 μm, and the flake-like graphite particles have an average particle size of 1-25 μm.

    摘要： Bearing assemblies, bearing components and related methods are provided for heavy load applications. In one embodiment, a bearing assembly includes a first bearing apparatus having a base member and a first plurality of polycrystalline diamond compacts (PDCs) on a first surface of the base member, the first plurality of PDCs defining a first collective bearing surface. A second bearing apparatus is configured to engage and slide over the first collective bearing surface. the second bearing apparatus may include a second plurality of PDCs defining a second collective bearing surface. The collective bearing surfaces may be configured to be substantially planar or substantially arcuate. Such bearing assemblies may be implemented in, for example, bridges, roadways, buildings, railways and other structures and machines that may require heavy load bearing support.

    摘要： A seal-bearing assembly to be inserted into the seal cavity of a mechanical device to provide a seal and a bearing surface to eliminate whip in a rotating and/or reciprocal cylindrical member. The seal-bearing assembly is particularly well suited for use in a reciprocal pump or a piston-driven valve, or between the steam lance and fixed steam tube in a sootblower. The assembly includes at least a pair of outer substantially rigid cylindrical bearings having an inner bore to be positioned over the cylindrical member and at least one complimentary flexible textile packing ring substantially comprised of carbon disposed between the two outer bearing members. In assemblies including an additional bearing, the additional bearing is surrounded by at least one flexible packing on each side. The inner bore of the bearing members provides a bearing surface for eliminating whip of the moving elements in the device.

    摘要： An all-graphite interferometer bearing assembly is introduced that allows the movement of a movable mirror in a Michelson interferometer without degradation during use. The assembly includes a stationary hollow graphite tube and a movable assembly which includes a mirror and a monolithic graphite member slidably disposed within the bore of the graphite tube that is composed of the same grade of graphite material as the monolithic graphite member. The result is a robust novel moving mirror arrangement in a Michelson interferometer that enables precise mirror alignment control, a long stroke length, excellent vibration damping and reduced sensitivity to external vibrations.

    摘要： In a slide member such as a slide bearing, the invention can make a height of a bank portion around an oil keeping concave portion small, whereby it is possible to improve an initial conformability and improve an anti-seizure performance. A plurality of holes are formed on a slide surface with respect to an opposing member by a fiber laser apparatus. At this time, in the case that a height of a bank portion generated in the periphery of the concave portions in accordance with the laser processing so as to bulge from a slide surface is set to t, and a depth of the concave portions from the slide surface is set to h, an energy density of the laser beam is adjusted such that a value t is equal to or less than 3 μm, and a rate t/h is between 0.1 and 0.5.
