How is the oil groove of the plain bearing processed?Boring, milling, or other methods of processing?What's the difference between oil grooves with different inner diameters?
1, with the processing of internal thread processing. 2. Pull out with a broach. 3. Pull out with special machine tools.
NC milling. Small rotary knife, bearing indexing and feeding numerical control.
Copper bushing lubrication groove processing methods are as follows: the pitch should be hung two times the length of the workpiece, the minimum speed, positive and negative threads of each car, the screw thread is fully optimized. Copper sleeve is divided into many kinds, including machine copper roller, copper bearing and so on. Oil lubricated bearings, used in various large and heavy machinery, is an important component of machinery. The copper sheath is of high hardness, excellent wear resistance, difficult to produce dead phenomenon, good casting performance and cutting performance, and good corrosion resistance in atmosphere and fresh water. 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. 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.
