Maintenance, overhaul and abnormal Countermeasures handling of fag bearing
In order to maintain the original performance of the bearing in good condition for as long as possible, it is necessary to maintain and repair in Countermeasures order to prevent accidents, ensure the reliability of operation and improve productivity and economy.
Maintain the operation standard of corresponding mechanical operation conditions and carry out it regularly. The contents include monitoring the Countermeasures operation status, replenishing or changing the lubricant, and regular disassembly inspection.
Damage and Countermeasures of fag bearing
Generally, if the bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidental and premature Countermeasures damage, which can not be 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, Countermeasures foreign matters invading from the outside, and insufficient research on the thermal effects of shafts and shells.
the clamping damage of the ring retaining edge of roller bearing can be considered as the reason. These reasons also coincide with insufficient lubricant, unsuitable, defects of oil supply and drainage structure, invasion of foreign matters, bearing installation error and excessive deflection of shaft.
Therefore, only investigating the bearing damage, it is difficult to know the real cause of the damage. However, if we know the use Countermeasures 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 Countermeasures several causes, we can prevent the recurrence of similar accidents.
Basic principle: use the resin with low surface energy to immerse the above nano materials into the cracks and surface phosphating film pores or gaps on the shallow surface of the bearing due to pure fire and stamping, and fully fill them.
Only under the microscope can you see the vertical and horizontal “gullies” on the bearing surface, so as to achieve the purpose of rust prevention and wear resistance.
In the surface treatment process of the bearing, it is generally used to immerse the bearing into the working surface instead of functional nano materials, so that its comprehensive properties such as rust prevention / corrosion prevention / wear resistance (prolonging service life) /
low friction coefficient / high temperature resistance / thermal expansion, contradiction balance between precision and gap, etc. are greatly improved, and the contradictory quality indexes are well balanced. This process is one of the key technologies for bearing quality.
Use lm-1198a super concentrated cleaning solution to remove the lubricating oil immersed in the microporous depth of the bearing phosphating layer, so as to make room for the resin replaced with molybdenum disulfide Press 0 for specific usage.
The proportion of 5% is mixed with water and the cleaning agent is heated to 85 ℃ to 99 ℃ (the dripping cleaning agent can be connected and reused after removing the oil beads floating on the surface after cooling).
The bearing workpiece is soaked in the cleaning agent and washed with a brush once, and then rinsed with clean water at a temperature of more than 70 ℃.
