In order to make the IKO bearing can maintain the performance and long-term use in good condition. We must check and maintenance on the bearings, inspection and maintenance is very important to the prevention of fault, in the operation to focus on examination of the rolling bearing noise, vibration, temperature and lubricant.
Using the factor of spherical bearings mainly refers to the installation and adjustment, maintenance, maintenance repair and other compliance with technical requirements. According to the requirement of bearing installation, use, maintenance, maintenance technology, which acted on the bearing in operation, speed, load, temperature, vibration, noise and lubrication condition monitoring and inspection, found abnormal immediately find reasons, adjustment, restore normal. Installation conditions is one of the leading factors in the use factor, the bearing is often caused by the installation of inappropriate stress state between the various parts of the complete bearing change, bearing an abnormal state operation and early ending life of internal factors mainly refers to the three major factors for structure design, manufacturing process and material quality determine the bearing the quality of the.
1 bearing in use process because of their quality and external conditions, the bearing capacity, the rotating precision and wear-resistant properties will change. When the performance index of spherical roller bearings is lower than the requirements and can not work normally, bearing failed or even failure, bearing failure and other unforeseen circumstances, machine, the device will stop there, loss of function and other abnormal phenomenon, therefore need to find out the causes in the short term, and take corresponding measures.
2 bearing vibration
Vibration of IKO imported bearings of bearing failure effect is obvious. For example: peeling, indentation, rust, crack, wear will be reflected in the bearing vibration detection, so the bearing vibration measuring device special (frequency analyzer and vibration meter) can measure the magnitude of vibration, the frequency distribution to infer the situation of abnormal vibration, the measured values, and different bearing conditions of use or the sensor installation location, therefore require prior to each machine measurement are analyzed and compared to determine the criterion.
3 bearing temperature
Usually the temperature of the bearing with the operation began to slowly rise, 1 to 2 hours later to reach a steady state at normal temperature of IKO bearing due to the heat capacity, the quantity of heat, the machine speed and load and different. If the lubrication, improper installation, bearing temperature will rise rapidly, there will be abnormal high temperature, then we must stop and take the necessary preventive measures.
The metallurgical quality of bearing materials are the main factors affecting the early failure of rolling bearings once. With the metallurgical technology (such as vacuum degassing of steel bearing) progress, improved quality of raw materials. Raw materials quality factors has been a marked decline in the proportion of bearing failure analysis, but it is still one of the main factors of bearing failure. Proper selection is still bearing failure analysis must be considered.
