Heat-sensing and operating skills for internally threaded rod ends

- Jun 01, 2018-

During the operation of internal-rod rod ends, the vibration of the rod-end joints is very sensitive to the damage of the rod-end joint bearings. To a certain extent, such as corrosion, crack, peeling, and indentation wear, etc., will be measured at the rod-end joint bearing vibration. This is reflected in the measurement. Therefore, the vibration measurement can be measured by using a special rod-end joint bearing vibration measurer, and the abnormal condition cannot be inferred from the frequency division.

When the internal thread rod end joint bearing is in operation, its measured value will be different because of the use condition of the rod end joint bearing or the sensor installation position. Therefore, when performing the operation, it is necessary to analyze and compare the measured value of each machine in advance. Determine the judgment criteria.

The temperature of the rod end of the internally threaded rod end can be inferred from the temperature of the outer surface of the rod end of the rod end during operation. If the temperature of the outer ring of the rod end can be directly measured by using the oil hole, then the temperature On the right. In general, the temperature of the rod end joint bearing gradually rises with the operation of the rod end joint bearing and reaches a stable state after 1-2 hours.

When the internal thread rod end joint bearing is used in the process of the thermal sensor, the working temperature of the rod end joint bearing can be monitored to a certain extent at any time, and the automatic alarm can be effectively realized when the temperature exceeds the specified value to a certain degree. And stop the accident to prevent the occurrence of a shaft accident.

The internal thread rod end joint bearing requires skilled operation skills in operation. To a certain extent, when the joint bearing is taken out from the heating oil tank or the heater, in this case, the oil on the surface of the joint bearing needs to be immediately wiped off with a clean cloth. Traces and attachments (be careful not to use cotton yarn), and then placed in front of the mating surface, in one operation to push the bearing to the shoulder. Always tighten during cooling, or use a small hammer to lightly press the joint bearing against the tight fitting sleeve. When installing the rod end joint bearing, the joint bearing should be slightly rotated to prevent the installation from being dumped or jammed.
