How does a sliding bearing move at work?
When sliding bearings work, sliding friction occurs; the magnitude of rolling friction depends mainly on the manufacturing accuracy; and the size of the sliding bearing friction depends mainly on the material of the sliding surface of the bearing. Plain bearings generally work with self lubrication functions; plain bearings are divided into non-metallic sliding bearings and metal sliding bearings in accordance with material.Sliding bearings (sliding, bearing) bearings that work under sliding friction.
Plain bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricant without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has a certain vibration absorption capacity. But the starting friction resistance is larger. The shaft supported by the bearing is called the journal, and the part that matches the journal is called the bush.
In order to improve the friction properties of the bearing surface, the antifriction material layer, which is cast on its inner surface, is called the bearing lining. Bearing and bearing lining materials are collectively referred to as journal bearing materials. The application of sliding bearings is usually under the condition of high speed and light load.
