Effect of air bubbles in lubricating oil for gearbox
Effect of air bubbles in lubricating oil for gearbox
(OP)
I'm loking after technical data about the oil emulsion (air bubbles) when used for gears lubricating and journal bearing.
Is there any risk for scuffing or surface effect like piting
Thank's

Come back with a little more details of your system.
RE: Effect of air bubbles in lubricating oil for gearbox
the main pump is a mechanically driven pump based one three screw witch induce foaming. We usually use another pump (based one two screw)
second one (for safety and low speed) is an electric one and is very well known
My experience shows that a (very)little quantity of air bubbles is not to dangerous my question is what will happen with 5%, 10% ?
Are they some experimental results on the evolution of viscosity and thermal efficiency of the lubricating oil

Also check with the oil pump manufacturer concerning your problem with air bubbles, he may have a fix.
I have never seen a paper on the permissible amount of air in oil. One has too many variables in each system to say the a certain percentage of air is acceptable or not.
We usually got concerned if we could see any air bubbles in a system.

I know also that one of the car manufacturers does the same testing, possibly BMW.
