What Are Some Of The Things To Pay Special Attention To When Running Bearings?

Do you know the matters needing attention when bearing is running? So let's see

Core tips: Machine operators and equipment maintenance engineers must maintain a high degree of vigilance in bearing fault signals, such as bearing noise, temperature rise and vibration. Machine operators and equipment maintenance engineers who detect bearings in operation must maintain a high degree of vigilance in the bearing "fault signals", such as bearing noise, temperature rise and vibration. The methods of detecting bearings in operation are: observation, listening and touch.

Observation: The bearing box should be opened periodically to visually inspect the bearing and oil seal, and check the condition of the oil seal near the bearing to ensure that they are sufficient to prevent hot liquid or corrosive liquid or gas from penetrating the bearing along the shaft.

Listen: Listening is a common way to identify irregularities. If the bearing is in good running condition, it will emit a low purring sound. If a sharp hiss, squeak and other irregular sound is emitted, it often means that the bearing is in poor operation. The sharp squeak may be caused by improper lubrication; Improper bearing clearance will also cause metal sound; Dents on the raceway of bearing outer ring will cause vibration, and cause smooth and crisp sound; If the percussion scars caused by installation will also produce noise, the noise will be different with the height of the bearing speed; If there is intermittent noise, it means that the rolling parts may be damaged; If there are pollutants in the bearing often cause hiss; Serious bearing damage will produce irregular and huge abnormal sound.

Touch: high temperature often indicates that the bearing has been in abnormal working condition, high temperature is also harmful to the lubricant of the bearing. If the bearing runs at a temperature above 120℃ for a long time, the bearing life will be greatly reduced. Causes of bearing operating temperature rise are: insufficient or excessive lubrication, lubricants contain impurities, excessive load, bearing damage, insufficient clearance and oil seal high friction and so on. Therefore, continuous monitoring of bearing temperature is necessary.
