Background
Sliding bearings, bearings that operate under sliding friction. The sliding bearing works stably and reliably without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, the friction loss and the surface abrasion can be greatly reduced, and the oil film also has certain vibration absorption capacity. But the starting frictional resistance is large. The portion of the shaft supported by the bearing is called the journal, and the part that mates with the journal is called the bearing shell. A layer of friction reducing material cast on the inner surface of a bearing shell to improve the friction properties of the surface is called a bearing lining. The materials of the bearing shell and the bearing liner are collectively referred to as sliding bearing materials. The sliding bearing is generally applied under the working condition of high speed and light load.
Although the friction resistance is small due to the action of the lubricating oil when the sliding bearing is used, the friction force is relatively large because the lubricating oil does not reach the outer surface of the bearing pad immediately after the sliding bearing is started.
