← ScienceWhich outcome occurs when industrial gearboxes use low-viscosity lubricants?
A)Increased wear due to boundary lubrication✓
B)Reduced heat transfer from gears
C)Decreased lubricant oxidation rate
D)Enhanced elastohydrodynamic film thickness
💡 Explanation
Increased wear arises because boundary lubrication occurs due to reduced oil film leading to increased contact between the gear teeth and inadequate surface protection; therefore wear increases rather than decreases in heat or oxidation.
