く、不純物も少ない。 In addition to a turbocharger, a turbo compound engine has a power recovery turbine and a gear train that transmits the power to the engine output shaft. Engine lubricating oil can also be used to lubricate the bearings of power recovery turbines, gears, and the bearings of the gear mounting shafts, but engine lubricating oil
Because it lubricates the high-temperature parts of the engine, it deteriorates rapidly and may contain impurities from the combustion part, so it cannot be said to be suitable for lubricating gears for high-speed turbo compound engines. On the other hand, in engines for construction machinery, there is a gear train called a power take-off (PTO) for extracting working power, and this gear and the bearing for the gear attachment shaft are lubricated with oil for transmission lubrication. ing. Unlike engine lubricating oil, transmission lubricating oil does not lubricate high-temperature parts, so there is less deterioration and less impurities.

ことにある。 The present invention was developed in view of the above circumstances, and its purpose is to always lubricate the lubricating parts on the power transmission mechanism side with transmission lubricating oil so that the high-speed gears, etc. of the power transmission mechanism can be lubricated with transmission lubricating oil. The purpose is to improve the life of gears by lubricating them with clean oil that causes less deterioration.
