Bearings are one of the most loaded engine components, and they are the ones that most often make themselves known by noise and hum. The ability to recognize a problematic sound in time allows you to replace the bearing before a serious accident.
What sounds are there?
- Smooth hum, increasing with speed - initial wear, drying out of the lubricant.
- Periodical knocking or clicking - cavities and chips on the raceways.
- Howling or whistling - a disadvantage lubrication, misalignment.
- Grinding - destruction of the separator, critical wear.
How to check
The simplest way is to listen to the bearing shield housing. Attach a screwdriver or stethoscope to the shield and evaluate the nature of the sound. Additionally check:
| Symptom | Conclusion |
|---|---|
| Shaft play when rocking | Excessive wear |
| Heating of the bearing shield | Lack of lubrication or misalignment |
| Vibration | Destruction of tracks |
When to change
Any extraneous sound from the bearing is a reason to replace the bearings. Grinding and play mean that it needs to be changed immediately: a damaged bearing allows the rotor to touch the stator, and this is already rewinding the winding and repairing the iron.
Sometimes at an early stage it is enough to replace the dried grease, but it will help to accurately assess the condition vibration diagnostics. Did you hear the hum of the bearings? Elektromotors engineers in Tashkent will quickly replace the bearings and prevent an accident - leave a request.
