Title:
LUBRICATING OIL COMPOSITION
Document Type and Number:
Japanese Patent JP2005320486
Kind Code:
A
Abstract:
To provide a lubricating oil composition for lubricating a sliding part wherein a contact pressure of about 800-2,000 MPa works as in the case of a gear and a bearing, which composition produces excellent antiwear characteristics and fatigue resistance characteristics.
The lubricating oil composition contains 5-20 vol% of a compound which has a 100°C viscosity of ≤1,000 Pa s under pressures of ≤700 MPa and gives one of ≥40,000 Pa s, due to becoming a glassy state, under pressures of ≥800 MPa.
