In the process of using the Entien bearing, there are often customers who reflect the abnormal temperature of the bearing vibration. According to the technical interpretation of the bearing group, the following factors are caused: the temperature of the general bearing rises as the speed of the bearing increases. And the temperature reached a stable level after 1-2 hours of stable operation. There are many main factors determining the temperature of the bearing, such as speed, lubricating oil, load, foreign matter intrusion and the like. If the above situation must be stopped, take the necessary inspection measures.
Customers are advised to monitor the operating temperature of the Endian bearing at any time using a thermal sensor. Long-term continuous rotation of the bearing at temperatures above 125 °C will reduce bearing life. Causes of high temperature bearings include: insufficient lubrication or excessive lubrication, lubricants. It contains impurities, the load is too large, the K bearing is damaged, the gap is insufficient, and so on. If it is not discovered and processed in time, the bearing will be scrapped. Therefore, it is necessary to continuously monitor the bearing temperature, whether it is measuring the bearing itself or other important parts. If the operating conditions are the same, any temperature change can indicate that a fault has occurred.
If the bearing produces abnormal vibration during operation, it is easy to cause damage. Specifically, it includes damage such as peeling damage, indentation damage, crack damage, and abnormal wear. Therefore, the vibration can be measured by the bearing vibration measuring device. The measured value is different depending on the operating conditions of the Entalion bearing or the mounting position of the sensor. We recommend that the customer record the value of the normal operation of the machine in advance to facilitate comparison. analysis.
The first type: observation method
If the bearing is well lubricated and properly blocks debris and moisture, it means that the oil seal should be free of wear. However, it is best to visually inspect the bearing and periodically check the oil seal when opening the bearing housing. Check the condition of the oil seal near the bearing. To ensure that they are sufficient to prevent hot liquids or corrosive liquids or gases from penetrating into the bearing along the shaft. The protective ring and the labyrinth oil seal should be greased to ensure maximum protection. The oil seal should be replaced as soon as possible if it is worn.
Second: Listening
It is best to use the sense of hearing to identify if the Entien bearing is working correctly. If the bearing is in good working condition, it will make a low humming sound. If it is a sharp hum, arpeggio and other irregular sounds, it usually indicates that the bearing is in poor working condition.
