Working and Disassembly Process of Spherical Oil Bearing in Powder Metallurgy Process

Before using the bearing bush device, the bearing bush material is wetted with lubricating oil, and the bearing can work without lubricating oil or without lubricating oil for a long time. This kind of bearing is called oil bearing. The ball bearing is made of metal powder and other antifriction material powder by binding, sintering, molding and oil immersion, and has a porous structure.

After soaking in hot oil, the pores are filled with smooth oil. During the operation, due to the suction effect of journal rolling and conflict heating, the metal and oil expand and push the oil out of the pores, so the conflict surface has a smooth effect. When the bearing cools, the oil is drawn back into the bore.

When the spherical oil bearing is working, the shaft is heated due to conflict and reverse rotation, the thermal expansion of the bearing pad reduces the porosity, and the lubricating oil overflows into the bearing clearance. After the important official stops rotating, the bearing bush cools, the air hole recovers, and the lubricating oil is sucked back to the air hole.

In order to assemble and disassemble the oil bearing more conveniently, tools should be selected first. When assembling and disassembling bearings, the applied force shall be stable and uniform without collision. This requires the use of oil pressure or tools capable of exerting a steady tension or pressure. When hammering is really needed, soft and debris free metal should also be used for buffering, such as copper sleeve, and the hammering force may be light.

Secondly, when installing the bearing, when the bearing has just been installed in the correct position, stop applying force to ensure that the end face of the ring is close to the end face or shoulder of the seat hole, so that it will not be squeezed too tightly or not installed in place. The bearing will wear more or less under accumulated use. In this case, we can adopt repair welding, casing insertion, pitting and other methods.
