The secondary cause of the bearing's presence in the process
is that the bearing is in place and the inner ring and the outer ring
are tilted when assembled, or that the load is present in the process of
assembly and assembly, and the bearing is finally formed.
When
the bearing is installed in accordance with the work norms to stop, or
will not form a lot of results, such as the form of the device or the
way did not, will form a bearing raceway surface and the formation of
bearings on the backbone of the emergence of linear marks. Deep groove ball bearing device indirectly reflects the use of bearings when the precision, the number of life and function.
Bearing
quality and other aspects are better, but the rolling bearing is a
precision component, its use must also be carefully carried out
accordingly. No matter how high the performance of the bearings, if used improperly, will not get the expected high performance. Even if the eyes can not see the small dust, will give the bearing a bad influence. Therefore, to keep the surrounding clean, so that dust will not penetrate the bearing. In the use of bearing a strong impact, will produce scars and indentation, as the cause of the accident. Severe cases, will crack, break, so must pay attention. Avoid using existing tools instead, and you must use the right tools. Pay attention to the corrosion of the bearing.
Operation of the bearing, the hands of the sweat will become the cause of rust. Pay attention to the use of clean hands, it is best to bring gloves as much as possible.
In
general, to control the bearing noise effects, must be based on the
root causes of these noise to take countermeasures in order to receive
the effect of the root causes. The main ways are:
Selection of low noise cylindrical roller bearings;
To avoid resonance with the host, to avoid the resonance sensitive speed;
From the application of cylindrical roller bearings to try to eliminate noise;
Additional measures for noise and muffler when other methods are invalid.
When the bearing temperature rises, first determine whether the malfunction, such as indeed increased, should do the following:
Check whether the cooling water pressure, water flow and piping system are normal. If the water pressure is low, the filter may be blocked, can not be
dealt with in time, can be shut down, when confirmed to work, and then
put into use.
The oil pressure of the governor should be checked and if the oil
pressure is low, the cooling water hydraulic valve may be closed.
Check whether the bearing has a different sound, and check the cylindrical roller bearing swing is abnormal.
Take the oil sample to see if there is any change in oil color and check for deterioration. If you confirm the deterioration, you should stop replacing the new oil.
Check the oil level is normal, if not normal, check the oil tank drain valve is tight. If it has been closed, should fill the oil, if it is sealed gasket oily, should be shut down.
