Cov kabmob muaj peev xwm txo qis kev sib txhuam ntawm ob qhov chaw txav los ntawm kev muab ib yam dab tsi los yob rau es tsis txhob swb– lawv yog ib qho tseem ceeb rau kev siv zog.
Qhov zoo, koj xav tau lub neej tshaj plaws ntawm koj cov kabmob, tab sis muaj ntau yam vim li cas bearings poob. Ib txhia ntawm cov laj thawj yog dab tsi?
Tsis txaus los yog Lubrication ntau dhau
Feem ntau ntawm lub sijhawm, bearings poob vim lawv tsis zoo lubricated. Tsis muaj roj nplua nyeem txaus, lubricant tsis ncaj ncees lawm, los yog kub dhau heev lawm degraded lub lubricant. 8 lub sij hawm tawm ntawm 10, bearings poob vim muaj teeb meem lubrication, yog li ntawd yog thawj qhov yuav tsum tau tshawb xyuas thaum tshawb xyuas thaum twg / vim li cas cov kabmob tsis ua haujlwm.
Cov kabmob kuj tuaj yeem ua tsis tau thaum cov khoom txawv teb chaws xws li av lossis steel chips nkag mus rau hauv cov kabmob lubricants lossis cov tshuaj ntxuav.. Lub lubricant yuav tsum tau lim. Tej chaw ua hauj lwm tej zaum yuav tau muab ntxuav.
Teeb meem Mounting
Yuav ua li cas rau mounting? Bearings yuav tsum tau mounted nrog ib tug xovxwm haum rau lub rotating nplhaib. Qee zaum cov nplhaib tawg, dent los yog hnav tawm. Tshawb xyuas lub mounting kom pom tias koj cov bearings puas raug lossis tsis raug.
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, lwm., 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. Kuj, 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.
