In actual work, the vibration degree of the internally threaded rod end bearing has obvious influence on its damage and performance. For example, peeling, indentation, corrosion, crack, wear, etc. will be reflected in the vibration measurement of the internal thread rod end bearing. come out. Therefore, the special rod end joint bearing vibration measuring instrument can measure the magnitude of the vibration, and distinguish the abnormal situation of the outlet by the frequency.
However, the vibration measurement of the internally threaded rod end bearing may vary depending on the conditions of use and the sensor mounting position. In view of this situation, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.
In addition, the temperature of the internally threaded rod end bearing will change to varying degrees. Normally, the temperature of the internally threaded rod end bearing rises slowly as the rod end joint bearing starts, and reaches a steady state after 1-2 hours. And its normal temperature will also vary depending on the heat capacity, heat dissipation, speed and load of the machine.
