In order to make the IKO bearing adhere to its proper function and long-term use under excellent conditions; it is necessary to view and protect the bearing; it is very important to check and protect against the problem; in the operation, it is necessary to check the rolling sound of the bearing. Oscillation, temperature and smoothing agent. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The application elements of the outer spherical bearing mainly refer to whether the equipment adjustment, application protection, protection repair, etc. can meet the skill requirements. According to the bearing equipment, application, protection, protection skills requirements; the load, speed, operating temperature accepted by the bearing in the operation Monitoring, oscillating, noise, and smooth conditions; finding abnormal causes to find the cause; making adjustments; making them recover normally. Equipment conditions are one of the primary elements in the application of the elements; bearings often incur the entire set of bearing parts due to improper equipment The change of the force situation between the two; the bearing is operating under abnormal conditions and completed in advance. The life connotation element mainly refers to the three major factors of structural quality, such as structural design, manufacturing process and data quality.
1. Bearings in the application process because of their own quality and external conditions; its bearing capacity, rotation accuracy and wear resistance will change. When the function index of the outer spherical bearing is lower than the application demand and cannot work normally; the bearing will suffer from defects or even failure; after the accident occurs, such as the failure of the bearing, the machine and equipment will stop; and various abnormal phenomena such as utility loss will be presented. Therefore, the demand for bearing people to find out the cause of the attack in a short period of time; and adopt the corresponding approach.
2. The temperature of the bearing generally increases the temperature of the bearing with the start of the operation, and reaches a stable condition after 1 to 2 hours. The normal temperature of IKO bearings is different due to the heat capacity, heat dissipation, speed and load of the machine. If it is smooth and the equipment is not suitable, the bearing temperature will rise sharply and it will show abnormal high temperature. At this time, it is necessary to stop and adopt the necessary precautions.
3. Oscillation of the bearings The oscillation of the IKO bearings has a significant effect on the failure of the bearings. For example, shedding, indentation, rust, cracks, wear, etc. will be reflected in the bearing oscillation detection. Therefore, after selecting a special bearing oscillation measuring device (frequency analyzer and oscillator, etc.), the amplitude of the oscillation can be measured, and the frequency is dispersed. The specific condition of the abnormal oscillation can be inferred. The measured value is different due to the operating conditions of the bearing or the orientation of the sensor equipment. Therefore, it is necessary to analyze and compare the measured values ​​of each machine beforehand and determine the specification.
The metallurgical quality of the outer spherical bearing data used to be the primary factor affecting the early failure of the rolling bearing. Following the advancement of metallurgical skills (such as vacuum degassing of bearing steel); the quality of the original data was improved. The original data quality factor was analyzed in the bearing failure analysis. The proportion has been significantly reduced; but it is still one of the primary influencing factors of bearing failure. It is still necessary to consider whether the selection of bearings is suitable for the bearing failure.
