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. The bearing bush is the part of the sliding bearing contacted with the shaft neck, is in the shape of a tile-shaped semi-cylindrical surface, is very smooth, is generally made of wear-resistant materials such as bronze, antifriction alloy and the like, and can be made of wood, engineering plastics or rubber under special conditions.

The bearing shell is divided into a single-piece type and a split type, and the single-piece type bearing shell is generally called a shaft sleeve (Bushing). The integral bearing bush has two types of oil grooves and oil grooves. The bearing bush and the shaft neck adopt clearance fit and generally do not rotate along with the shaft.

When the sliding bearing works, direct friction exists between the bearing bush and the rotating shaft, the friction can generate high temperature, and the phenomenon of bush burning can be caused due to overhigh temperature, so that the service life of the sliding bearing is shortened.
