During the use of IKO bearing, due to its own quality and external conditions, its bearing capacity, rotation accuracy and antifriction performance will change.
In fact, anything in use will reduce its service life.Problems and Judgment Skills of IKO Plastic Bearing in use
Problems and Judgment Skills of IKO Plastic Bearing in use
When the performance of the bearing is lower than that required by the normal operation, it is often called that the bearing will be damaged by accident, but when it stops working, it will not be damaged. Therefore, it is necessary to investigate and deal with the causes in a short time and take corresponding measures.
Of course, the damage of rolling bearing is much more complex than that of general mechanical parts. The damage of plastic bearing is characterized by many manifestations and complex causes.
In addition to the internal factors of bearing design and manufacturing, most of the damage of IKO bearing is due to improper use, unreasonable support design, improper installation and poor lubrication, Poor sealing and other external factors.Problems and Judgment Skills of IKO Plastic Bearing in use
1. Observation: if the bearing is well lubricated and free of sundries and moisture, it indicates that the oil seal of IKO bearing is not worn. If the original bearing box is opened, visually check the plastic bearing and regularly check the oil seal.
Check the condition of the oil seal near the bearing to ensure that they are sufficient to prevent hot liquid, corrosive liquid and gas from penetrating into the bearing along the axis. If the oil seal is damaged, replace it as soon as possible.
Check the automatic lubrication system to ensure that the oil or grease enters the combined bearing, and ensure the correct addition amount.
At the same time, check whether the lubricant is discolored or black. If so, it usually indicates that the lubricant contains impurities, which is also harmful to the use of IKO bearing.Problems and Judgment Skills of IKO Plastic Bearing in use
2. Listening: using hearing to identify irregular operation is a very common method. For example, using a screwdriver or electronic stethoscope to detect a simple abnormal noise is a method often used by experienced operators and maintenance personnel.
If the IKO bearing is in good running condition, it will make a low whine sound. For example, when the plastic bearing makes a sharp hiss, squeak and other irregular sounds, it may indicate that the bearing is in bad running condition.Problems and Judgment Skills of IKO Plastic Bearing in use
3. Touch: high temperature often indicates that IKO bearing has been in abnormal condition, and high temperature is also harmful to the lubricant in the bearing. However, the high temperature of the bearing is caused by the lubricant in the combined bearing at some times.
If the bearing operates for a long time at a temperature exceeding 120 ℃, the service life of the bearing will be reduced. The causes of high temperature of plastic bearing include insufficient or excessive lubrication of lubricant, impurities in lubricant, excessive load, damage of IKO bearing, insufficient clearance and friction caused by oil seal.
Under normal circumstances, the bearing will have a natural temperature rise just after lubrication or after lubrication, and it will last for one to two days.Problems and Judgment Skills of IKO Plastic Bearing in use
Seeing here, we should know some factors of IKO bearing damage, so it is of great significance to study the formation and causes of plastic bearing damage.
On the one hand, we can improve the use method, use the bearing correctly, give full play to the due efficiency of the bearing, and on the other hand, it is helpful to develop new products with better performance.Problems and Judgment Skills of IKO Plastic Bearing in use
