Title:
LUBRICATING OIL COMPOSITION, LUBRICATION METHOD, AND TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2023/058440
Kind Code:
A1
Abstract:
Provided is a lubricating oil composition containing, as component (A), a base oil having a kinematic viscosity at 40 °C of 3,000 mm2/s to 20,000 mm2/s, and containing, as component (B), a base oil having a kinematic viscosity at 40 °C of 100,000 mm2/s to 2000,000 mm2/s, wherein the flash point of the component (A) is at least 180 °C, the content of the component (B) is 0.01 mass% to 2.00 mass% with respect to the total amount of the lubricating oil composition, and the lubricating oil composition satisfies high levels of: fuel-efficiency due to a low viscosity and a low transition coefficient; wear resistance; usability due to a high flash point; and low-temperature fluidity. Also provided are: a lubrication method using the same; and a transmission comprising the same.
