Measure speaker size and sound quality of the rolling sound of FAG bearings in operation to be checked, FAG bearings, even a slight peeling and other damage, will send out abnormal tone and irregular sound, able to distinguish between measured sound device.
Listen
Hearing to identify irregular operation is a very common method. For example: With the electronic stethoscope to check the feel of certain parts is not normal noise is often the method used by the experienced operator.
FAG bearings in a good state even turn will issue a muffled hum sound. If issued a sharp hissing sound, squeaky sound, and other irregular sounds, often FAG bearings in bad situation even turn.
Sharp squeaking noise may be caused due to improper lubrication. Inappropriate FAG bearing clearance can also cause a metallic sound. FAG Bearings on the outer orbit of the concave track dent can cause vibration, and cause a smooth and crisp sound. As the installation percussion scars will produce noise, this noise will vary with the speed of the level of FAG bearings.
If intermittent noise, said rolling elements may be damaged. This sound occurs when damage to the surface is rolling out of date, if FAG bearing pollutants often cause a hissing sound. Serious with the Order of damage to the irregular and huge noise.
FAG bearing damage of course, by listening to perceived, but usually have to FAG bearings must be replaced immediately can not be. Therefore, a better way such as the use of condition monitoring, such as electronic instruments. More accurate than the old method using a stick Estimated FAG Bearings situation.
