The sounder is used to check the size and sound quality of the rolling sound of the running bearing.
Even if the bearing has slight peeling and other damage, it will emit abnormal sounds and irregular sounds, which can be distinguished by the sounder.
Using hearing to identify irregular movements is a common method. For example, using an electronic stethoscope to detect abnormal noise in a part is a method used by experienced operators.
If the bearing is in a good continuous state, it will make a low hum.
If a sharp voice is heard, the voice and other irregular sounds often indicate that the bearing is in a bad transition condition. A sharp voice may be caused by improper lubrication.
Bearing damage can be detected by hearing, but usually the bearing must be replaced at this time. Therefore, a better method is to use the skf electronic condition monitoring instrument. Compared to the old method, a wooden stick or a screwdriver is used to abut the bearing housing, and the other end is attached to the ear. The new invention ensures a safer and more accurate estimation of the bearing condition.
