Lubrication requirements and temperature conditions of stainless steel rod end bearings

- Sep 03, 2018 -

The temperature of the stainless steel rod end bearings can be estimated from the outside of the rod end joint bearing. If the oil hole can directly measure the outer ring temperature of the rod end joint bearing, it is more suitable. 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 with the heat capacity, heat dissipation, speed and load of the machine.

If the stainless steel rod end bearing is lubricated and the mounting part is suitable, the temperature of the rod end joint bearing will rise sharply and abnormal temperature will occur. At this time, it must stop running 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.

The stainless steel rod end bearings can be assembled with the assembly sleeve and the small hammer to install the end rod joint bearing, and the hammering force should be uniformly transmitted to the entire circumference of the end surface of the rod end rod joint bearing ring, so the end face of the assembly sleeve subjected to the hammering should be Made into a sphere. The force required to install the end rod joint bearing is related to the size of the joint bearing and the amount of interference. For medium or large joint bearings with large interference, the method of hot charging is commonly used. Before hot loading, put the end rod joint bearing or the separable joint bearing ring into the fuel tank or special heater and heat evenly to 80-100 °C, not more than 100 °C.
