Nope - common misconception!
When you're engineering a gear set, you need to select the correct film
strength so that the clearances BETWEEN the epicyclic surfaces do not
come in contact. A gear set typically is an unpressurized application.
The more power being transmitted the higher the film strengh needed -
and there is a correlation of (kinematic) viscosity (viscous shear) and
what it will support in load without "squeezing out" and permitting
metal to metal contact. ...... totally unlike a pressurized
application like a hydrodynamic bearing journal, although the
mathematics is the same.
