Occurrence of micropitting in gear teeth contacts is often studied using component level tests FZG back-to-back rig being perhaps the most common example. Although such rigs may be useful in ranking different lubricants in terms of their resistance to micropitting in gears, they do not allow for a systematic study of the influence of various contact parameters on the occurrence of micropitting because they do not provide independent control of the relevant contact variables, in particular coefficient of friction, speSee more on gearsolutions pdf a review on micropitting studies of steel gearsGearbox Typical Failure Modes, Detection and Mitigation pdf a review on micropitting studies of steel gearsMake pinion 2 HRC points harder than gear Use oil with high micropitting resistance Keep lubricant cool, clean, and dry Use high-viscosity lubricant pdf a review on micropitting studies of steel gears Optimize gear geometry/accuracy Use nitrided steel Grind/hone/superfinish gear teeth Coat gear teeth with phosphate, Cu, AgGear micropitting initiation of ground and superfinished pdf a review on micropitting studies of steel gearsApr 22, 2021 · This paper investigates the resistance of micropitting on two materials, using an FZG back-to-back test rig with C-PT gears.
