The core of installation and maintenance of
Tapered Roller Bearings is to ensure assembly accuracy, avoid pollution and damage, and regularly inspect and lubricate them in order to extend their service life.
一、 Installation precautions
1.Clean the bearings, shaft necks, and bearing seat holes before installation, remove oil stains, iron filings, and other impurities to avoid wear on the raceway after assembly.
2.Use appropriate installation tools, prioritize press fitting or hot fitting (temperature not exceeding 120 ℃), and prohibit direct tapping of the outer or inner ring of the bearing to prevent damage to the rollers and raceways.
3.Control installation clearance, tapered roller bearings are often installed in pairs (face-to-face or back-to-back), and the pre tightening force needs to be adjusted according to the working conditions. Over tightening can easily generate heat, while over loosening can cause vibration.
4.Ensure coaxiality, and the roundness and cylindricity of the shaft neck and bearing seat holes must meet the requirements. After installation, check the flexibility of operation and ensure there is no jamming or abnormal noise.
二、 Maintenance precautions
1.Regularly check the lubrication status, select appropriate lubricating grease or oil according to the working conditions, avoid grease aging and drying, and generally replenish or replace it every 1000-2000 hours of operation.
2.Keep the working environment clean, prevent dust and moisture from entering the bearings, replace seals in a timely manner when damaged, and avoid lubrication failure and corrosion.
3.Regularly monitor the operating status, pay attention to bearing temperature (normally below 80 ℃), vibration, and noise. In case of abnormal increase or noise, stop the machine for inspection in a timely manner.
4.When the machine is shut down for a long time, the bearings need to be treated with rust prevention. Anti rust grease can be applied or sealed for storage to avoid corrosion caused by humid environments.
