The causes of motor bearing damage:
In the process of operation of industrial equipment, the damage of motor bearings is a common problem. In order to further explore this phenomenon, this paper will conduct a detailed analysis from three aspects: the specific manifestations of injury, possible causes and preventive measures.
First, the specific manifestation of motor bearing damage:
Through the observation and analysis of the actual state of the motor bearing, it can be found that the damage is usually manifested in the following forms:
- 1. Spalling of the surface of the rolling body: this is one of the most typical characteristics of bearing damage, which is manifested as obvious spalling or pits on the surface of the rolling body, seriously affecting the normal operation performance of the bearing.
- 2. Cage deformation or fracture: due to long-term excessive load or poor lubrication, the cage may be deformed or even broken, resulting in the failure of the entire bearing system.
- 3. Raceway wear intensifies: Abnormal wear occurs on the raceway surface due to excessive friction or foreign body intrusion, which further affects the accuracy and life of the bearing.
- 4. Abnormal temperature rise: When the motor bearing internal failure, may be accompanied by a significant rise in temperature, which is also one of the important indicators to judge the health of the bearing.
Second, the main causes of motor bearing damage
The occurrence of bearing damage is often the result of a combination of factors, the following are several key reasons:
- 1. Improper installation: If the bearing is not strictly in accordance with the specifications during installation, such as applying too much axial or radial force, it may lead to uneven distribution of initial stress, which lays a hidden danger for subsequent damage.
- 2. Insufficient lubrication or wrong lubricant selection: lubrication is the core link to ensure the normal operation of bearings. If the lubrication dose is insufficient, the grease deteriorates or the selected lubricant does not match the working condition, it will accelerate the wear process of the bearing.
- 3. External environmental impact: dust, moisture or other pollutants enter the bearing inside, easy to cause corrosion or increase friction resistance, thereby shortening the service life of the bearing.
- 4. Overload operation: When the electric length is in the working state beyond the design load range for a long time, the pressure on the bearing will increase correspondingly, and eventually lead to fatigue damage.
Preventive measures and improvement suggestions
To solve the above problems, effective preventive measures can be taken from the following aspects:
- 1. Optimize the installation process: ensure that the bearing installation process meets the relevant technical standards to avoid potential risks caused by human error. At the same time, special tools are used to reduce the damage to the bearing assembly.
- 2. Strengthen lubrication management: regularly check the effectiveness of the lubrication system, and adjust the lubrication cycle according to the actual situation. In addition, high-quality lubricants suitable for specific working conditions should be selected to ensure the safety of the lubrication process.
- 3. Improve the working environment: prevent external impurities from invading the bearing through the sealing device, and control the ambient temperature and humidity level to reduce the impact of adverse factors on the bearing.
- 4. Implementation of condition monitoring: the use of vibration analysis, temperature detection and other means to real-time monitoring of bearing operating status, timely detection and processing of early signs of failure, so as to extend the service life of bearings.
To sum up, motor bearing damage is a complex and multifaceted problem, which needs to be comprehensively analyzed and effectively prevented from the root. Only through scientific and reasonable maintenance strategies can we maximize the reliability of bearings and the overall performance of equipment.
