    摘要: The invention relates to a big end bearing shell (4, 6) for a connecting rod (2), consisting of titanium or a titanium alloy. The shell comprises a support layer (8, 20) consisting of steel and an anti-friction layer (16, 26) for the crankshaft. According to the invention, the back of the support layer (8, 20) is clad with a layer (10, 22) of tin bronze material, with a thickness of 10-50 nullm to prevent fretting corrosion and frictional abrasion.

    摘要: There is provided a fluid dynamic pressure bearing apparatus including a shaft, a bearing sleeve rotatably supporting the shaft, and a lubricating oil filled between the shaft and the bearing sleeve, wherein at least one of the shaft and the bearing sleeve is formed of a copper alloy containing 0.8 wt % to 5 wt % of lead, and a base oil of the lubricating is a member selected from the group consisting of monoester, dibasic acid diester, diol ester and mixtures thereof, and the lubricating oil contains 0.1 wt % to 1 wt % of condensed phosphate ester. The fluid dynamic pressure bearing apparatus is capable of suppressing the hydrolysis of the lubricating oil, and the wear of the shaft and the bearing sleeve.

    摘要: A component made from a preform made of a first material and having a bearing seat defining a bearing seat surface, and a method of producing the component. The component includes a bearing cap portion, and a remainder portion split from the bearing cap portion and adapted to mate therewith. The method comprises the step of coating the bearing seat surface of the preform with a second material different from the first material for providing a bearing layer made of the second material on the bearing seat surface, the bearing layer having a running face. The step of coating includes the step of thermal spraying the second material on the bearing seat surface. The preform is separated into the bearing cap portion and the remainder portion. The bearing layer is split by fracture separation at a separation region of the bearing layer into a bearing cap bearing layer portion corresponding to the bearing cap portion, and a remainder bearing layer portion corresponding to the remainder portion.
