What are the problems we should pay attention to when setting oil holes and oil grooves on plain bearings?
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.
When the oil and oil grooves are set on the sliding bearings, it should be noted that the oil holes and oil grooves can only be opened in the non bearing areas; the axial oil grooves can not be opened along the bearing width to prevent leakage.Sliding bearings (sliding, bearing) bearings that work under sliding friction.
