table 4 table of physicochemical properties of running-in oil in examples
As can be seen from the data in the table, the viscosity indexes of the running-in oils in the above examples 1-3 are all greater than 110, which indicates that the running-in oils in the examples 1-3 all have good viscosity-temperature properties; apparent viscosity at-40 ℃ is smaller than 150000 mPa.s, pour point is smaller than-40 ℃, and the low-temperature fluidity is good, so that the starting at the ambient temperature of-40 ℃ or even lower can be ensured; the maximum seizure-free load is greater than 785N and FZG is greater than 12, which indicates that the embodiment has very good extreme pressure abrasion resistance and can provide good extreme pressure friction abrasion protection for running-in of a gearbox and a drive axle.
2. Running-in bench test
The viscosity index and pour point performance of example 1 above were excellent, and a small run-in bench test was performed using example 1 and a conventional run-in oil, which was purchased from fowls, no. 15 machine oil, as follows:
table 5 results of run-in bench test of example 1 and conventional run-in oil
As is clear from the above table, after the running-in oil in example 1 is run-in for the drive axle and the gearbox, the key indexes such as the kinematic viscosity at 40 ℃ and 100 ℃, the acid value and the additive element are changed normally, and the running-in oil in example 1 has the universality of the running-in for the drive train such as the gearbox and the drive axle by the small running-in bench test in the table.
From the aspects of pollutant grade codes and iron element analysis, after the running-in oil in the embodiment 1 is run in, the pollutant grade is normal, the iron element content is stable, and the running-in oil in the embodiment 1 can provide a better cleaning and protecting function for a transmission running-in device; from the analysis of silicon element, compared with the traditional running-in oil, the running-in oil in the embodiment 1 has stable silicon element content after running-in, which indicates that the silicon sealant is less precipitated and has better compatibility with the silicon sealant.
From the data of the circulation period after running-in, the pollution degree exceeds the standard after the traditional running-in oil circulates for 30 days, and meanwhile, the pollution elements of iron, silicon, sodium and calcium are enriched, so that the running-in test running requirement cannot be met after the traditional running-in oil circulates for 30 days. In the embodiment 1, after the running-in oil is recycled for 1 year, various analysis data still meet the running-in application requirement of a drive train, the service life is greatly prolonged by more than 24 times, and the running-in oil meets the running-in test running requirement and prolongs the service life on the premise of ensuring the universality of a gearbox and a drive axle.
