First, the use of roller component bearing note the following:
(1) To keep the bearing and its turnover clean
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.
(2)Be careful to use
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.
(3)Use the appropriate operating tools
Avoid the use of existing tools to replace the tools, you must use the appropriate tools. We often emphasize the importance of tools, because there are too many customers in the installation of the wrong tools used to cause damage to the bearing.
(4)Pay attention to the corrosion of the roller 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 try to bring gloves.
Steel printing is clear: the bearing body will be printed on the brand words, labels and so on. The font is very small, but most of the products are produced by the use of stamping technology, and before the heat treatment before the pressure word, so the font is small, but concave – deep, very clear.The counterfeit product font is very vague, because the printing technology is rough, the font floating on the surface, and some even easily can be wiped out by hand.
Whether there is a noise: the left hand holding the bearing sleeve, right hand toss the jacket to rotate, listen to whether there is a noise.As most of the counterfeit products production conditions behind, completely hand-workshop operation, in the production process will inevitably be mixed into the sand – a class of impurities, hidden in the bearing body, so when the rotation will be issued a noise.This is the biggest difference between the strict implementation of the production standards and the operation of the machine.
Does the surface have turbid oil traces: This should pay special attention when buying bearings. As the current domestic anti-rust technology is not particularly home, so the rust-proof body when the bearing body is easy to leave a thick oil traces, in the hand sticky – thick sticky,While the original foreign bearings almost do not see the traces of anti-rust oil, it touches on a particularly careful expert said the bearings smell a taste, certainly under the anti-rust oil, just do not see it.
Chamfering is uniform: the so-called bearing chamfer, that is, the intersection of the horizontal and vertical, counterfeit bearings due to the limitations of production technology, in these corners of the disposal of unsatisfactory.
Second, roller bearing bearing maintenance.
In order to maintain the bearing’s performance in good condition for as long as possible, it is necessary to maintain and repair it in order to ensure the reliability of the operation, to ensure the reliability of operation, and to improve the productivity and economy.Maintenance of the best operating conditions of the corresponding mechanical operating conditions, regular. Contents include, monitoring the operating status, replenishing or replacing the lubricant, and checking for periodic disassembly.As the maintenance of the operation, there are bearings of the rotating sound, vibration, temperature, the state of the lubricant and so on.
Third, the bearing damage and countermeasures
In general, if the bearing is used correctly, it can be used until the fatigue life is reached.But there will be accidental premature injury, not resistant to the use of the situation. This early damage, relative to fatigue life, is limited to the quality of use known as a malfunction or accident.More due to the installation, use, lubrication on the attention, from the external invasion of foreign body, for the shaft, the shell of the thermal impact of the study is not enough and so on.
On the bearing damage, such as: roller bearing rings of the ribs of the card injury, as a reason can be considered, lack of lubricant, not suitable for the drainage structure defects, foreign body intrusion, bearing installation error, shaft deflection Too big, there will be these reasons coincide.
Therefore, only to investigate the roller bearing bearing damage, it is difficult to know the real cause of damage. However, if you know the use of machinery bearings, the use of conditions, the structure around the bearing to understand the situation before and after the accident, combined with the bearing damage and several reasons to study, you can prevent the recurrence of similar incidents.
