During the inspection, mainly Maintenance And observe whether the rivet head of the bearing is skewed, loose and whether the welding position is correct.
The welding of cage is good or bad. Whether the welding point is too small, the welding is not firm, or the ball clamping caused by excessive welding. These are the places that need special attention in the process of testing fag Maintenance And bearings. There are also some problems that need attention.
Now let’s share with you the local inspection of bearing in many years of work experience. First of all, in the environment, the inspection of fag bearing should be carried out in the environment with light, which is astigmatism, so as to better observe the outside of fag bearing and see that there are no cracks
and other abnormalities on its surface. For example, the wear, scratch and collision in the Maintenance And process of mechanical cloud will lead to the deviation of fag bearing device, resulting in poor device position, flat load and stress concentration, and the reduction of precision and service life of modeling fag bearing.
1. Maintenance, overhaul and abnormal handling of fag bearing
In order to maintain the original performance of the bearing in Maintenance And good condition for as long as possible, it is necessary to maintain and repair in order to prevent accidents, ensure the reliability of operation and improve productivity and economy.
Maintain the operation standard of corresponding mechanical Maintenance And operation conditions and carry out it regularly. The contents include monitoring the operation status, replenishing or changing lubricants, and regular disassembly inspection.
As maintenance items in operation, there are bearing rotation sound, vibration, temperature, lubricant state, etc.
Generally, if the bearing is used correctly, it can be used until the Maintenance And fatigue life is reached. However, there will be accidental and premature damage, which is not resistant to use.
This early damage, as opposed to fatigue life, limits the use of quality known as failure or accident. Most of them are caused by careless installation, use and lubrication, foreign matters invading from the outside, and insufficient research on the thermal effects of shafts and shells.
As for the damage state of fag Maintenance And bearing, for example, the clamping damage of the ring retaining edge of roller bearing can be considered as the reason.
These reasons can also coincide with insufficient lubricant, unsuitable, defects of oil supply and drainage structure, intrusion of foreign matters, bearing installation error and excessive deflection of shaft.
Therefore, only investigating fag bearing damage, it is difficult to know the real cause of the damage.
However, if we know the use Maintenance And machinery, service conditions, the structure around the bearing, understand the situation before and after the accident, and investigate the damage state of the bearing and several causes, we can prevent the recurrence of similar accidents.
Precautions for the use of fag bearings are as follows:
Keep fag bearings and their turnover clean
Even small dust that cannot be seen by the eyes will have a bad impact on fag bearings. Therefore, keep the surroundings clean so that dust will not invade fag bearings.
Use with care
Strong impact on fag bearing in use will produce scars and indentation, which will become the cause of the accident. In serious cases, it will crack and fracture, so we must pay attention to it.
Use appropriate fag operating tools
Avoid replacing with existing tools and bearing tools, and appropriate tools must be used. We often emphasize the importance of tools because too many customers use the wrong tools in installation, resulting in the damage of fag bearings.
Pay attention to the corrosion of fag bearing
Sweat on your hands can be a cause of rust when operating fag bearings. Pay attention to operate with clean hands and wear gloves as much as possible.
