First, the problems of the maintenance technology of KOYO imported bearings:
The two major problems related to KOYO's imported bearing maintenance technology are: 1. When to change the oil. 2. How much oil should be changed? If the oil change is too small, the bearing will be scrapped in advance; if the oil change is too much, KOYO bearings will be in trouble or long-term damage to the power coil and coil.
Second, KOYO imported bearing maintenance technology:
The way to determine when to lubricate and when to stop oiling is simple: monitor when developing a baseline, setting up an observation schedule, and filling the oil.
1. Develop a basic line
The KOYO imported bearing base line reflects the decibel strength under normal operating conditions, no visible errors, and sufficient lubrication.
Three ways to develop a baseline:
1), comparison method: If there are multiple KOYO bearings of the same type, these bearings can be put together for comparison. Use the same test method or observe each bearing from the same angle. Analyze the decibel intensity and sound quality. If there is no essential difference (less than 8 dB), we can set it as the base decibel strength of each KOYO bearing.
2) Set the basic line when adding lubricating oil: When adding lubricating oil, listen to the intensity of the sound, when the sound intensity drops and then rises. At this time, do not add too much oil, and set it as the basic line.
3) History: Observe the decibel strength of KOYO bearings, record them daily, and then compare the results of 30 days. If the decibel intensity changes little or no (less than 8 decibels), we can set this as the baseline and use it for later comparisons.
2, set the observation timetable
Equipment criticality associated with total production, environmental results, and operational results is a major factor in selecting and setting up an evaluation mechanical system. It is very necessary to test once a month after the basic observation line is established. For high-decibel KOYO bearings that are to be lubricated, the frequency should be detected more frequently so that changes that may occur are observed. If a KOYO bearing is in a state of destruction, the lubricant can only temporarily cover up the error. However, the decibel intensity will rise quickly to show the existence of the error. In some cases, this phenomenon will appear in a few minutes, while others will take several days.
