Bearing failure refers to serious failure or Irreversible process damage of the bearing during use. Bearing failure may be caused by a variety of reasons. The following are some common Failure cause of bearings:
1. Fatigue failure: During long-term use or high-speed rotation, bearing failure caused by fatigue loading is a common situation. Frequent load changes lead to material fatigue cracking and peeling inside the bearing, leading to failure.
2. Overload failure: When the bearing is subjected to a load that exceeds its load-bearing capacity, it can lead to bearing failure. Overload may be caused by improper design, abnormal operating conditions, or external factors such as collisions and vibrations.
3. Poor lubrication: Bearings require good lubrication to reduce friction and wear. If the quality of the lubricating oil or grease is poor, the oil supply is insufficient, or there are pollutants, the friction of the bearings increases, which may lead to poor lubrication and bearing failure.
4. Spectral resonance: When the working frequency is close to the natural frequency of the bearing, it will cause spectral resonance, causing excessive bearing vibration and ultimately failure.
5. Environmental factors: Pollutants, humidity, corrosive media, etc. in the environment may also cause damage to bearings and may lead to failure. For example, acidic gases, moisture, and chemicals can cause bearing corrosion, rust, and damage.
6. Installation and maintenance issues: Improper installation and maintenance may also lead to bearing failure. For example, incorrect disassembly, assembly that is too tight or loose, and the use of incorrect tools or methods can all damage bearings.
7. Material or manufacturing deficiencies: Material quality or manufacturing process issues in bearings may lead to inherent structural deficiencies, which may gradually expand and cause failure during use.
To prevent bearing failure, it is necessary to choose the appropriate bearing type, install and maintain it correctly, and regularly inspect and replace it according to actual working conditions. In case of bearing failure, failure analysis can help determine the Failure cause and take corresponding measures to avoid the recurrence of similar problems.
