摘要： PROBLEM TO BE SOLVED: To provide a hard carbon coating sliding member capable of providing very excellent wear resistance and low friction characteristics under the presence of lubricating oil in, for example, an internal combustion engine by remarkably improving the friction characteristics on the uppermost surface of the sliding member while making use of the characteristics of a resin material with high elasticity.
SOLUTION: In a base material formed of a steel material and an aluminum material, an elastic layer formed of rubber or resin or formed by adding additive particles such as solid lubricant to the rubber or resin is formed, as an intermediate layer, on a portion slid on a mating material through lubricating oil. Also, a hard carbon coating such as DLC is formed on the surface of the intermediate layer.

摘要： PROBLEM TO BE SOLVED: To provide a cam lobe for an assembled camshaft with competitive manufacturing costs capable of preventing breaks caused by extending works of a tube.
SOLUTION: The cam lobe 30 comprises a base circle portion 31 arranged on a through-hole 32, and a nose 34 extending outward to a radial direction rather than the base circle portion 31. The cam lobe 30 is fastened on an outer periphery of a shaft material by radially extending the shaft material after inserting the circle-shaped shaft material into the through-hole 32. A material of the cam lobe is composed of case hardening steel, and surface hardening treatment is applied to the cam lobe after it is formed to a cam shape. The relationship of a radial thickness T (mm) between an inner periphery of the through-hole 32 and an outer periphery of the base circle 31 with a radial depth D (mm) within a range having hardness of 550HV or more around the inner periphery of the through-hole 32 satisfies an expression of D≤0.4167T-1.0 (however, T≥2.4).

摘要： PROBLEM TO BE SOLVED: To improve a surface property of a cast iron member containing graphite, and improve the frictional condition, by making the surface of a cast iron member containing graphite corrode, or further by combining grinding and lapping before and after the corrosion of the surface. SOLUTION: In parts of an engine, in the environment the cast iron containing graphite is used in the portion where the frictional condition is severe, the surface is corroded, or grinding and lapping is applied before and after this process. As a corrosion method, a chemical corrosion method due to acid, and an electrolytic polishing method for corroding the surface by adding electrolysis are defined. Since the projections in the interface of graphite produced by this working are removed, in the case where the object is hard material, the effect due to the removal of the projections is significantly produced. Especially, in the case of the surface hardness of HRC 55 or more, the effect is remarkably produced. The surface roughness Ra before the corrosion treatment is to be 0.20 or more, and the lower limit of the surface roughness Ra before the corrosion treatment is to be 0.01.

摘要： PURPOSE: To provide a rolling body of less temperature dependency and excellent traction characteristic with regard to a metal made power transmission rolling body for transmitting power by means of interposing traction oil between the rolling bodies by specifying the initial surface roughness of the rolling body with respect to the average surface roughness. CONSTITUTION: Regarding a metal made power transmission rolling body used for a continuously variable transmission and the like for transmitting power by means of interposing traction oil between the rolling bodies, the initial surface roughness of the rolling body is formed so that it may be within the range of 0.1 to 0.5m by an average surface roughness Ra. By setting the average surface roughness within a specific range, traction coefficient improves in the domain of high oil temperature and temperature dependency of the traction characteristic can be drastically reduced. Such high bearing rolling body is constituted of combination of favorably a driving side rolling body and a driven side rolling body, which have recessed shape cone rolling body surfaces, and a protruded shape power roller, which rolls as being sandwiched between both cone rolling bodies.
