Patent ID: 8901049

Claim:
A sliding mechanism, comprising: a plurality of sliding members made of a steel material, wherein at least one sliding surface of at least one sliding member of the plurality of sliding members is coated by a titanium nitride-based material, wherein a diesel engine oil to which molybdenum dithiocarbamate has been added with molybdenum in an amount of at least 600 ppm and at most 1000 ppm is interposed between the plurality of sliding members as a lubricant, wherein an arithmetic mean roughness of the plurality of sliding members is of at least 2 nm and at most 10 nm, and wherein lubricating conditions are such that a Sommerfeld number is at least 2.12365×10 −19 and at most 5.94509×10 −19 , upon converting a viscosity thereof to Pa·s, a speed to s −1 , and a load to mean Hertzian stress (Pa).
