Bearing manufacturer: Slewing bearing fault identification method and maintenance precautions

Bearing manufacturer: The slewing bearing is one of the indispensable parts in mechanical equipment. However, once the slewing bearing fails, it is likely to cause poor operation of the entire mechanical equipment and affect production efficiency and quality. The slewing bearing failure must be discovered and handled in time. So, what are the methods for identifying slewing bearing failures? What are the precautions during maintenance?　　

Bearing manufacturer: Slewing bearing failure identification method

1. Lubricant identification method

　　Bearing manufacturer: The fault of the slewing bearing can be identified by the state of the lubricating oil. The specific method is to take samples of the lubricant for analysis, observe its degree of contamination, and determine whether foreign matter or metal powder is mixed in. This method is particularly effective for judging slewing bearings or large slewing bearings that cannot be observed at close range.

　2. Temperature identification method

　　Bearing manufacturer: The identification by the working temperature of the slewing bearing is a comparative identification method and is used in situations where the operating status of the slewing bearing does not change much. Therefore, it is necessary to record the temperature continuously. When the slewing bearing fails, the temperature will not only rise but also change irregularly. It is recommended to combine the working temperature identification with the sound identification.

　3. Voice recognition method

　　Bearing manufacturer: The failure of the slewing bearing can be identified by sound, but this method requires rich experience and sufficient training to identify the sound of the slewing bearing and the sound of non-slewing bearing. For this reason, we should try our best to assign someone to do this job. By sticking a listening device or listening rod on the outer casing, the sound of the slewing bearing can be clearly heard, thereby judging the failure and cause of the slewing bearing.

Bearing manufacturer: slewing bearing maintenance precautions

　　1. Record the appearance of the slewing bearing

　　Bearing manufacturer: When the slewing bearing fails during the use of mechanical equipment, the appearance of the slewing bearing should be recorded and the remaining amount of lubricating oil in the slewing bearing should be checked when the slewing bearing is disassembled for maintenance. After the lubricating oil is sampled and stored, kerosene or gasoline should be used to simply clean the slewing bearing.

　2. Rough wash first and then fine wash

After rough cleaning, clean the disassembled slewing bearing, place the slewing bearing on the container, and place a metal mesh as the bottom to prevent the slewing bearing from directly removing dirt from the bottom of the container. During rough cleaning, avoid the slewing bearing rotating with the dirt to damage the rolling surface of the slewing bearing. After cleaning the adhesive and grease with a brush, proceed to the fine cleaning step, put the slewing bearing in the cleaning oil, and clean it while rotating. If the cleaning oil is dirty, replace it in time to ensure a good cleaning effect.

　3. Check the slewing bearing

Bearing manufacturer: In order to ensure that the disassembled slewing bearing can continue to be used, it must be inspected after cleaning. The inspection items of the slewing bearing include: foreign matter, clearance, dimensional accuracy, slewing bearing frame Wear, mating surface condition, rolling surface condition, raceway surface condition, ball or roller running condition, etc.
