Although the bearing of the jaw crusher is not large, it plays an important role in the machine. The protection of bearings is also an important task, so this article summarizes several points that need to be paid attention to. Customers and manufacturers who are willing to use them to strengthen the prevention, the following are the precautions for jaw crusher bearings.
1. Pay attention to the cleaning of bearings. Pay attention to cleaning the bearings during daily use. Different types of bearings have different cleaning methods. For example, ball bearings are generally cleaned with gasoline and then dried; sliding bearings are generally cleaned with diesel. During the cleaning process, a brush can be used to remove the dirt on the bearing surface, then the oil is appropriately heated, and then the balls and holes inside the bearing are carefully cleaned.
2.Pay attention to the temperature of the bearing. Pay attention to the temperature of the bearing during operation, and keep the bearing in a good lubricating state. If the shaft temperature is too high, check the bearing lubricating oil to see if the oil hole is blocked, the oil cannot be added, the lubricating oil does not meet, or because of the bearing The wear is severe and the bearing temperature is too high. After that, you should also pay attention to whether the sound and vibration are abnormal (this article called Failures analysis of jaw crusher bearing details the cause and solution of the bearing temperature is too high).
3. Pay attention to the inspection of bearings. After the jaw crusher is working for a period of time, periodic inspections are required. Remove the bearing, if the bearing wear is less, it can be turned on the lathe to reach the correct geometry. At the same time, we must pay attention to the gap between the eccentric shaft and the bearing bush and the mandrel and the bearing bush. If it exceeds 1.5 times, it should be replaced or cushioned.
4.Pay attention to bearing lubrication. Lubrication is not only the key to the bearing, it is very important for the entire jaw crusher. The volume of lubricating oil filled in the bearing seat is 40-70% and must be clean and free of any impurities; when applying oil lubrication, cover all roller surfaces, After the coating is completed, the position of the outer ring is restored, and it is necessary to cover the dust with plastic film. (For details, please check this article called Precautions for bearing lubrication of jaw crusher)
After the jaw crusher is shut down, the bearing and related components should be fully inspected, such as tightening bolts or replacing failed bolts, to ensure that there are no obstacles when the machine is used next time.
