For the rod end joint bearing, if there is vibration problem during the operation, it will certainly bring a series of effects, such as flaking, indentation, rust, crack, wear, etc., which will be on the rod end. The measurement of the vibration of the joint bearing is reflected in the measurement. Therefore, the vibration measurement can be measured by using a special bearing vibration measurer, so that the abnormal condition cannot be inferred by means of the frequency division.
At the same time, the measured data will also be affected by factors such as the use conditions of the rod end joint bearing. Therefore, it is necessary to analyze and compare the measured values of each machine beforehand to determine the judgment criteria. For its temperature, it can generally be inferred from the temperature of its outdoor surface, if the use of oil hole can directly measure the bearing outer ring temperature, it is more appropriate.
In practical applications, the temperature of the rod end joint bearing gradually increases with the operating time, and usually reaches a stable state after one or two hours. In addition, the normal temperature of the rod end joint bearing will also change due to the machine's heat capacity, heat dissipation, speed, and load.
