Roller bearing parts of the maintenance of the technical problems related to the maintenance of the two major technical problems are: 1. 2, how much oil should be changed. If the oil is too small, the bearing will be scrapped in advance; if the oil is too much, roller bearing parts will be in trouble or long-term damage to the power coil and coil. Make a baseline, make an observation plan, and monitor when filling.
Set up the roller bearing parts bearing observation schedule such as the total output, environmental results, operating results related to the key equipment is to select and set the main factors to evaluate the mechanical system. Once the basic observation line is developed, it is necessary to test once a month. For the high decibel bearings to be lubricated, the frequency should be detected more frequently, so that it can be observed that it may change. If a bearing is about to be destroyed, the oil can only temporarily mask the error. However, the decibel level will rise quickly to show that the error exists.
The development of a base line idler roller bearing base line is reflected in the normal operation, with no visual errors, and sufficient lubrication under the condition of DB strength.
1) comparison method: if you have the same type of bearings, these bearings can be put together to compare. Observe each bearing with the same test method or from the same angle. Analysis of decibel intensity and sound quality. If there is no essential difference (less than 8 dB), we can set it up to the base decibel of each bearing. In some cases, this phenomenon will appear in a few minutes, while others will take a few days. Check if a bearing is more than 8 dB below the base line, we believe that the roller bearing is lubricated. When we realize that the bearing is in need of lubrication, it is important to know when to stop it.
2) when adding lubricating oil to set the base line: when adding lubricating oil, listen to the intensity of the sound, when the sound intensity decreased and then increased. At this point, do not add too much oil, and set it as the base line.
3) historical records: observed bearing decibel intensity, daily records, and then compare the results of 30 days of recording. If the change in the intensity of the DB is small or not (less than 8 dB), we can set it up as a base line and compare it to the results observed in the future. |
