Check the oil pressure of the governor.), the magnitude of the vibration can be measured, and the specific abnormality can be inferred from the frequency distribution. Long-term continuous rotation of bearings at temperatures exceeding 125°C will reduce bearing life.
Each collision has a different intensity, and the vibration amplitude changes periodically, showing an amplitude modulation phenomenon. Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants. If it does rise, you should do the following: The time-domain vibration waveform of a normal bearing is shown in Figure 1 below.
Under normal circumstances, when the bearing is in motion, four situations will be displayed, namely, normal bearing vibration, fixed outer ring vibration with damage point, rotating inner ring vibration with damage point, and rolling element vibration with damage point. This situation is similar to the damage points on the inner ring, and the vibration amplitude changes periodically, depending on the period.
Based on their knowledge of bearings, they can share the impact of vibration and temperature on the work of bearings. The influence of temperature on the bearing High temperature often indicates that the bearing is in an abnormal condition
