    Abstract: In order to improve conformability of a sliding surface of a sliding member in an early state of sliding, there is provided a sliding member in which a plurality of holes are formed on a sliding surface, and the diameters (or the opening area) of the holes on the sliding surface are arranged so as to become gradually large as it gets closer to both ends in an axial direction from the center side in the axial direction. This feature decreases the pressurized area as it gets closer to the ends of the sliding surface so that it wears at an early stage, whereby a conformed surface following the deflection of a mating member is provided.

    Abstract: The object of the present invention is to provide a lubricant which is of non-pollution and substitutable for conventional lubricants and which is excellent in lubrication characteristics, particularly low frictional characteristics. According to the present invention, the lubricant comprises an aqueous solution containing a saccharide in an amount of 0.5-30% by mass based on the total amount of the aqueous solution and the reminder of water (pure water), said saccharide comprising mainly a sucrose and a disaccharide caramel in an amount of 0.2-20% by mass based on the amount of the sucrose. As the sucrose, granulated sugar or crystal sugar is preferred, and coffee sugar containing previously a disaccharide caramel can also be used. More preferably, the lubricant contains sodium laurate and/or potassium laurate in an amount of 0.001-1% by mass. Furthermore, it is desired that the lubricant contains potassium sorbate in an amount of 0.1-3% by mass as a preservative and benzotriazole or an alkali metal salt thereof in an amount of 0.1-3% by mass as a rust inhibitor.

    Abstract: There is provided a method of forming a coat on an inner surface of a bearing, in which a jig 13 is attached to a rotor 2 while holding four bearings 12 for example, so as to form those in a cylinder shape. Then, while the rotor 2 is rotated at a circumferential speed of 0.3 m/sec, a nozzle 8 for airless spraying is inserted into the rotor 2, so that the nozzle 8 injects a coating material 30 from the inside of the bearings 12 toward an inner surfaces of the bearings 12 to apply the coating material thereon. Because the coating material 30 is injected from the nozzle 8 without using compressed air, the fly amount of the coating material is made less as compared to air spray painting.

    Abstract: There is provided a half thrust bearing having a constant bearing wall thickness between a slide surface and a back surface, and including an approximately flat center region and two end regions on both circumferential sides of the center region. Each end region extends from each circumferential end of the half thrust bearing toward a circumferential center over a circumferential angle of 5° or more and 35° or less. A reference surface is defined as an imaginary plane which is perpendicular to an axial direction of the half thrust bearing, parallel to the slide surface in the center region, and located away from the slide surface. An axial distance between the slide surface and the reference surface is minimum in the center region, and continuously increases circumferentially from a center region side toward a circumferential end side at any radial position in each end regions.

    Abstract: A sliding member includes a resin overlay layer on a sliding-surface side of a bearing alloy layer. The resin layer includes a resin binder and 20% by volume or more of solid lubricant particles with an anisotropic shape dispersed in the resin binder. The sliding surface is located at 0° and has a virtual axis perpendicular to the sliding surface at 90°. An angle θ is formed by a straight line and a major axis of the particles. The total number of the particles in a observation region is N. A rate R1=N1/N of the number N1 of first particles at the angle θ of 70°≤θ≤90° from among the particles is 3%≤R1≤20%, and a rate R2=N2/N of the number N2 of second particles with the angle θ being θ≤20° is 35%≤R2≤65%.

    Abstract: A sliding member includes a base material and an alloy layer that includes Cu as a main component and Bi and having a sliding surface formed on a side opposite to the base material. The alloy layer has a first region and a second region. The first region is set to a region taking up 30% of the thickness of the alloy layer which is from an interface in contact with the base material toward the sliding surface. The second region is set to a region taking up 10% of the thickness of the alloy layer which is from the sliding surface toward the base material. A larger number of Bi phases having larger cross-sectional areas are distributed in an arbitrary observation cross section as Bi phases included in the second region compared to Bi phases included in the first region.
