Rod end joint bearings are installed in the same way as ordinary bearings. The inner ring or outer ring is fixed, and the circlip or shaft clamp is used. The bearing capacity of the joint bearing is very high and it is not sensitive to concentricity. However, because it belongs to the bearing steel contact surface sliding bearing, it is not good in heat resistance, wear resistance and lubrication, and is suitable for low-speed transmission.
When installing rod end joint bearings, a press is generally used, but if there is a lack of equipment, the same can be done, as long as the assembly sleeve and a small hammer are used, and the hammer is used to increase the hammering force. Evenly spread to the entire circumference of the end face of the device ferrule. At this time, the assembly sleeve will become spherical due to the hammering.
The amount of force to be applied during installation depends on the size of the joint bearing and the size of the matching interference. If it is a medium or large joint bearing with a large interference, it should be hot-mounted, as long as it is hot-mounted Put the rod end joint bearing into the fuel tank and heat it evenly with a dedicated heater, and try to keep it between 80 to 100 percent .
Then take out the bearing, wipe off the oil stains and attachments on the surface with a clean cloth, and then push the joint bearing to the place where it is against the shaft shoulder. The bearing will gradually cool down, and the medicine will always be kept tight during this process. , Or use a small hammer to tap the joint bearing through the assembly sleeve to make it tight. Another point to remember is that the rod end joint bearing needs to be rotated a little bit to install, which can mainly avoid some failures.
Because the outer ring of the rod end joint bearing and the housing hole can be fitted into the joint bearing after being heated when the housing is tightly fitted, it is easy to damage the mating surface in this case. Therefore, it is necessary to heat the rod end joint bearing to prevent the performance of the component from being affected.
