Whether it is installing a rod end joint bearing or disassembling a rod end joint bearing, the staff is required not only to possess skillful operation and energy saving, but also to pay attention to some details to ensure that the rod end joint bearing can be smoothly loaded and unloaded, and to ensure that the bearing itself is intact. Sex.
Under normal circumstances, the staff is using a press to install the rod end, but if the lack of or can not use the equipment, you can use the assembly sleeve and hammer to install rod end bearing, hammering force should be uniform It is transmitted to the entire circumference of the end face of the rod-end joint bearing ring, so that the hammered end face of the assembly sleeve should be made spherical.
The force required to install the rod end joint bearing is related to the size of the joint bearing and the size of the fitting interference. For the medium or large rod end joint bearing with large interference, the hot loading method is commonly used. It should be noted that, before hot loading, put the rod end joint bearing into a fuel tank or a dedicated heater and heat evenly to 80-100 °C. Do not exceed 100 °C.
Hot rod end joint bearings require skilled operation skills. Immediately after the bearing is removed from the heating tank or heater, clean the oil and traces of the joint bearing surface with a clean cloth. Then place it in front of the mating surface and in one operation push the rod end bearing up against the shaft shoulder.
During the cooling process of the rod end joint bearing should always be tightened, or with a small hammer to tap the bearing through the assembly sleeve to make it close; not only that, when installing the rod end joint bearing should be slightly rotated joint bearing to avoid the installation dumping or Card stuck.
When the outer ring of the rod end joint bearing and the housing hole are tightly fit, the shell can be heated and then loaded into the joint bearing, especially the joint bearing of light metal material. In the tight fitting process, the rod end joint bearing should be heated firstly. To avoid damage to the mating surface by pressing in the outer ring.
