1. Maintenance and overhaul of imported bearings
In order to maintain the original performance of the bearing in a good condition for as long as possible, it is necessary to maintain, repair, and prevent accidents, ensure the reliability of operation, and improve productivity and economy. Maintenance is best carried out on a regular basis in accordance with the operating standards for the mechanical operating conditions. The contents include monitoring of operating conditions, replenishment or replacement of lubricants, and inspections for periodic disassembly.
As a maintenance item during operation, there are bearing rotation sound, vibration, temperature, lubricant state, and the like.
2. Damage and countermeasures of imported bearings
In general, if the bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidents that are prematurely damaged and are not resistant to use. This early damage, as opposed to fatigue life, limits the quality of what is known as a fault or accident. Many of them are caused by inadvertent installation, use, and lubrication, and foreign objects intruding from the outside are insufficiently studied for the thermal effects of the shaft and the outer casing.
Regarding the damage state of the imported bearing, for example, the jam of the ferrule of the roller bearing, as a cause, the lubricant is insufficient, unsuitable, the defect of the oil supply structure, the foreign matter intrusion, the bearing installation error, the shaft deflection If the song is too big, there will be coincidences of these reasons.
Therefore, it is difficult to know the true cause of the damage by only investigating the damage of the imported bearings. However, if you know the mechanical use of the bearing, the conditions of use, the structure around the bearing, and the situation before and after the accident, combined with the damage state of the bearing and several reasons, it can prevent similar accidents from happening again.
3. The precautions regarding the use of imported bearings are as follows:
(1) Keep imported bearings and their turnover clean
Even small dust that is invisible to the eyes can have a bad effect on imported bearings. Therefore, keep the area clean so that the dust does not intrude into the imported bearings.
(2) Use with care
In the use of the imported bearings, strong impact, will produce scars and indentations, which is the cause of the accident. In severe cases, cracks and breaks occur, so care must be taken.
