Three causes of gearbox failure MRO Magazine

May 17, 2018· Even a small amount of misalignment can cause premature gear wear and failure. The gear teeth will not mesh the way they were designed to, resulting in excessive loads in the weaker parts of the teeth. Bearings rotating in their bores can also cause wear in the bores, in turn causing misalignment and gear damage.

12 Reasons Why Bearings Fail Reliable Plant

High temperatures can cause grease to bleed (purge the oil), which reduces the lubricant’s efficiency. In elevated temperature conditions, oxidation can lead to the loss of lubricating oils from the grease, leaving a dry, crusty soap that can seize the bearing. Higher temperatures also reduce the hardness of the metal, causing early failure.
