Best time to determine bearing repair
What state to transfer to better repair of rolling bearings, NSK bearings damage patterns and characteristics to judge. With the greatest amount of medium and small bearing damage, usually by rings or rolling fatigue and excessive wear. When bearings are rolling entering the third stage of wear on the surface, or pitting and spalling have emerged, the bearings will quickly tend to fail, the Raceway surface damage has been very severe, repairs are difficult, or repair value has been lost.
Before but bearing in the stage, wearing relatively minor, fatigue only in rolling surface under surface layer may occur within a few microns to dozens of Micron depth, thus bearing repair at this point, you can use a small price to pay for better repair effect. In General, with particular emphasis on rolling bearing repair when the bearings have worked for quite some time, has been fully utilized, and before damage occurs into repairing the most appropriate.
Bearing repair method of timing of
To the specific judgment method for repair of NSK bearings, approaching that bearings are already fully used to undermine the specific judgment as follows:
1) using the bearing working status monitoring instrument
Such as ferrograph type or SPM or I-ID-1 working status monitoring instrument to determine the bearing bearing bearing when you should be working and decisions to be repaired, this is the most convenient and reliable way.
For example when the HD-1 instrument is used, and when the pointer by the warning zone close to the danger zone, and after taking measures such as improved lubrication does not return a pointer, you can identify is the problem of NSK bearings, you can take advantage of when had not yet reached the danger zone, bearing repair. Exactly how far away from the danger zone begins to be repaired, can be adjusted by experience.
Using this equipment, you can take full advantage of potential bearing, bearing to be repaired in a timely manner, and avoids the failure occurred are safe and economical.
2) using a simple tool monitoring
In the absence of the above devices, the operator can be armed with rods or tools such as wrenches machine shell parts of the subject closest to the bearing, listening ears ashamed of tools by NSK bearing operation from the tool, use modified medical stethoscope or you can, of course.
Normal of NSK bearing running sound should is uniform, smooth does not harsh of sound, and does not normal of bearing running sound is has variety of intermittent, impact sexual or harsh of sound. first to habits Yu normal of bearing running sound, then on can grasp judgment does not normal of bearing running sound, then through practice experience of cumulative, and further can analysis out what of does not normal sound corresponds to Yu what of bearing does not normal phenomenon. Many categories of abnormal sound of bearings, difficult to indescribable, primarily based on the experience accumulated.
