INA integral eccentric bearings may have noise problems during operation, usually due to installation, lubrication or other external factors. The following are common methods to eliminate and solve eccentric bearing noise:
1. Check installation problems
Alignment check: Make sure the bearing is well aligned with the shaft and seat hole. If the bearing is not installed correctly or the force is uneven, it will cause running noise.
Installation tightness: Check whether the bearing is installed too tight or too loose, adjust the installation clearance, and avoid noise caused by assembly problems.
Tool use: Use special tools for installation to avoid damage to the bearing due to knocking or improper installation.
2. Lubrication problems
Grease check: Determine whether the grease or lubricant used is suitable for the bearing, whether it is sufficient and uniform.
Clean lubrication channels: Clean the lubrication channels of the bearing and related components to prevent foreign matter from causing poor lubrication.
Replace lubricant: If the lubricant is deteriorated or contains impurities, it needs to be replaced in time.
3. External environment inspection
Foreign matter contamination: Check whether there are pollutants such as dust and particles entering the bearing operating environment, and install dust seals if necessary.
Temperature is too high: Check whether the bearing operating temperature is within the allowable range to avoid lubricant failure or noise due to overheating.
Vibration source investigation: Check whether the vibration of other mechanical equipment is transmitted to the bearing, causing abnormal noise.
4. Bearing inspection
Damage inspection: Check whether the bearing rolling elements, inner and outer rings and retainers are worn, cracked or deformed.
Replace bearings: If the bearing is severely worn or damaged, it is recommended to replace new bearings.
5. Operation adjustment
Operation speed: Check whether the equipment operation speed exceeds the bearing design range.
Load balance: Ensure that the load on the bearing is evenly distributed to avoid unilateral overload.
6. Professional maintenance
If the above methods cannot solve the problem, it is recommended to contact professional bearing technicians for comprehensive inspection and maintenance. INA manufacturers can also provide professional technical support and solutions.
Most noise problems can be effectively solved by checking one by one and taking appropriate measures.
