Industriële laers verminder wrywingskragte tussen twee bewegende dele deur 'n oppervlak iets te gee om op te rol eerder as om oor te gly– hulle is deurslaggewend vir bewegingstoepassings.
Ideaal gesproke, jy wil die meeste lewe uit jou laers haal, maar daar is verskeie redes waarom laers misluk. Wat is sommige van daardie redes?
Nie genoeg of te veel smering nie
Meeste van die tyd, laers misluk omdat hulle nie behoorlik gesmeer is nie. Daar is ook nie genoeg smeermiddel nie, die verkeerde smeermiddel, of oormatige temperature het die smeermiddel afgebreek. 8 tye uit 10, laers misluk as gevolg van smeerprobleme, so dit is die eerste ding om na te gaan wanneer jy ondersoek wanneer/waarom laers misluk.
Laers kan ook misluk wanneer vreemde stowwe soos vuil of staalskyfies in laersmeermiddels of skoonmaakoplossings beland. The lubricant might need to be filtered. Work areas might need to be cleaned.
Mounting Issues
What about mounting? Bearings should be mounted with a press fit on the rotating ring. Sometimes the rings crack, dent or wear out. Inspect the mounting to see if your bearings are properly or improperly mounted.
Sometimes things get out-of-square, including shaft shoulders, spacers or clamping nuts. Loose fits can cause misalignment, leading to overheating and separator failure.
Miscellaneous Issues
If you see linear wear marks in the axial direction at the rolling-element pitch, there could be false brinelling.
If you notice red or brown stains on rolling elements, raceways, etc., moisture, acid or grease could cause corrosion, and this corrosion is abrasive to the surfaces of ball and roller bea63rings.
Electrical damage could be the cause of bad bearings. Ook, fatigue due to overloading can cause bearings to not function properly when there’s an excessive preload and/or tight inner-ring fits. Excessive loads and/or overheating can also cause failure.
