The swivel rod ends is sensitive to the damage of the rod end joint bearing during operation. For example, its peeling, indentation, rust, crack, wear, etc. are reflected in the vibration measurement of the rod end joint bearing, so The special rod end joint bearing vibration measuring device (frequency analyzer, etc.) can measure the magnitude of the vibration, and the specific situation of the abnormality cannot be inferred by the frequency division. The measured value differs depending on the conditions of use of the rod end joint bearing or the position at which the sensor is mounted. Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.
The temperature at the end of the swivel rod can be inferred from the temperature outside the product when it is used. It is more suitable to directly measure the temperature of the outer ring of the rod end joint bearing by using the oil hole during the operation. Usually, the temperature of the rod end joint bearing starts to rise slowly as the rod end joint bearing starts, and reaches a steady state after 1-2 hours. The normal temperature of the rod end joint bearing varies depending on the heat capacity, heat dissipation, speed and load of the machine.
If the lubrication and installation parts are suitable, the temperature of the rod end joint bearing will rise sharply, and abnormal high temperature will occur. At this time, it is necessary to stop the operation and take necessary precautions. The thermal sensor can be used to monitor the working temperature of the rod end joint bearing at any time, and automatically alarm or stop the occurrence of the burning shaft accident when the temperature exceeds the specified value. www.wxjwbearing.com
