Operation of rod end bearings

Operation of rod end bearings:

1. Where the press is missing or cannot be used, the end rod joint bearing can be installed with an assembly sleeve and a hammer. The hammering force should be evenly transmitted to the entire circumference of the end face of the end rod articulated bearing ring, so the end face of the mounting sleeve should be made spherical.

2. The force required to install the end rod articulated bearing is related to the size of the articulated bearing and the amount of interference with the fit. For medium or large articulated bearings with a large amount of interference, hot-fitting is commonly used. Put the end rod articulated bearing or detachable articulated bearing ring into the fuel tank or special heater before heating, and evenly heat it to 80-100 ℃, not more than 100 ℃.

3. Hot-rolled spherical plain bearings require skilled operating skills. When the joint bearing is removed from the heating oil tank or heater, immediately wipe the oil stains and attachments on the surface of the joint bearing with a clean cloth (note that cotton yarn cannot be used), and then place it in front of the mating surface. The joint bearing is pushed against the shoulder of the shaft. During the cooling process, always push tightly, or tap the joint bearing tightly with a small hammer through the assembly sleeve. When installing the end rod joint bearing, the joint bearing should be rotated slightly to avoid the installation from falling or getting stuck.

4. When the outer ring of the end rod joint bearing and the housing hole are tightly fitted, the housing can be heated and installed into the joint bearing. Especially for light metal joint bearings, during the tight fitting process, the mating surface may be damaged due to the pressing of the outer ring. In this case, the end rod joint bearing should be heated first.
