摘要:
A low-friction sliding member in a transmission is at least one of sliding members which are in slidable contact with each other in presence of a transmission oil composition. The low-friction sliding member includes a base material having a sliding section. A hard carbon thin film is coated at a sliding surface of the sliding section of the base material. The hard carbon thin film contains hydrogen in an amount not more than 20 atomic %. The transmission oil composition contains at least one of organic oxygen-containing compound and aliphatic amine compound.

The invention provides a low-friction sliding mechanism, a low-friction agent composition, a friction reduction method, a manual transmission and a final reduction gear unit that can exert very excellent low friction characteristics to sliding surfaces present under various applications, and, in particular, that have more excellent low friction characteristics than that of a combination of an existing steel material and an organic Mo compound. The low-friction sliding mechanism has an oxygen-containing organic compound or an aliphatic amine compound interposed between sliding surfaces that a DLC coated sliding member and a sliding member form. The low-friction agent composition contains an oxygen-containing organic compound or an aliphatic amine compound. The friction reduction method includes supplying the low-friction agent composition between sliding surfaces that a DLC coated sliding member and a sliding member form. The manual transmission includes, as at least one of sliding members, a DLC coated sliding section. The final reduction gear unit includes, as at least one of sliding members, a DLC coated sliding section.

摘要:
The present invention relates to a system wherein a pair of relatively movable, facing DLC contact surfaces at least one of which is coated with a DLC film, are further lowered in friction, and the low friction property is stably maintained. The present invention also relates to a lubricant for the system, and a lubricating method. The lubricant for the system having the DLC contact surfaces contains lubricant base oil (A) mainly composed of base oil (X), and sulfur-containing molybdenum complex (B). The base oil (X) is at least one of hydrocracked mineral oils, wax-isomerized mineral oils, and poly-α-olefin base oils, and has a kinematic viscosity of 2 to 20 mm2/s at 100° C., a total aromatic content of not higher than 5 mass %, and a total sulfur content of not higher than 0.005 mass %.

摘要:
A sliding mechanism includes a contact area between at least two sliding members. A low friction coating is applied on at least a portion of one of the at least two sliding members at the contact area. The low friction coating is a hard carbon including a diamond like carbon material selected from the group consisting of diamond, amorphous a-C diamond like carbon (DLC), and amorphous a-C:H DLC. A grease is applied on the low friction coating, wherein the grease comprises a base oil selected from the group consisting of ester oils, ether oils and combinations thereof.
