The sound detector is used to check the size and sound quality of the
rolling noise of the bearing in the operation. Even if the bearing has a
delicate peeling and other hazards, abnormal sounds and irregular

A sound measuring device is used to check the size and sound quality
of the rolling noise of the bearing in the operation. Sliding
self-lubricating bearings are used. Even if the bearing has a delicate
peeling and other hazards, abnormal sounds and irregular sounds will be
declared, which can be distinguished with the sounding instrument.
Using hearing to identify irregular assignments is a very common method. For example, the use of an electronic stethoscope to detect abnormal
noise in a part is often experienced by experienced operators.
If the bearing is in a good state of continuous rotation, it will declare a low level of restlessness. If you declare a sharp voice, arpeggios and other irregular movements, often indicate that the bearing is in a bad state.
Sharp noise can be caused by improper lubrication. Oil-free bearing bushes Improper bearing clearance can also constitute a metallic sound. The
dents in the concave track on the outer ring of the bearing will cause
vibrations and will create a smooth and smooth movement. If noise is generated due to knocking on the equipment, the noise will be different from the bearing speed.
If there is intermittent noise, indicate that the roll can be damaged. This movement occurs when the damaged surface is pressed and expired. Contaminants in the bearing often cause squeaking. Severe corollary damage can occur with irregular and unrelenting noise.
