Title:
LOW-FRICTION SLIDING MECHANISM, LOW-FRICTION AGENT COMPOSITION AND METHOD OF FRICTION REDUCTION
Document Type and Number:
WIPO Patent Application WO/2005/014761
Kind Code:
A2
Abstract:
A low-friction sliding mechanism, low-friction agent composition, method of friction reduction, manual transmission and final reduction gear, which realize exhibition of strikingly excellent low-friction characteristics on sliding surfaces existing in various uses, especially exhibition of low-friction characteristics superior to those of conventional steel material/organic Mo compound combinations. In particular, there is provided a low-friction sliding mechanism comprising an oxygenous organic compound, an aliphatic amine compound, etc. interposed between sliding surfaces made by DLC coated sliding member and sliding member. There is further provided a low-friction agent composition comprising an oxygenous organic compound and an aliphatic amine compound. There is still further provided a method of friction reduction, comprising feeding a low-friction agent composition onto sliding surfaces made by DLC coated sliding member and sliding member to thereby attain lubrication. Still further, there are provided a manual transmission having at least one of sliding members provided with a DLC coated sliding zone, and provided a final reduction gear having at least one of sliding members provided with a DLC coated sliding zone.
