V. Wikstrom et B. Jacobson, LOSS OF LUBRICANT FROM OIL-LUBRICATED NEAR-STARVED SPHERICAL ROLLER-BEARINGS, Proceedings of the Institution of Mechanical Engineers, Part J, Journal of engineering tribology, 211(J1), 1997, pp. 51-66
The time to lubricant film breakthrough in an oil-lubricated spherical
roller bearing has been measured using SKF Lubcheck for various setti
ngs of bearing load, outer ring temperature, shaft speed and oil type
and viscosity. The bearings were lubricated once and then run to film
breakthrough with the aim of estimating the lubricant losses under dif
ferent conditions. The result of the experiments supports the theory o
f lubricant replenishment, and it is shown that high speed combined wi
th high lubricant viscosity will shorten the time to film breakthrough
.
