The oil injected from the upper part of the SKF bearing seat and the outer side of the bearing seat (toward the roll head) in Taizhou can not enter the rolling mill bearings well and is easy to be lost, resulting in poor oil conditi*** in the rolling process of the bearing working face, leading to early failure.
Therefore, the oil circuit of the bearing seat is improved, and the oil injection nozzle is added to the inner side of the bearing seat (towa*** the roller body) to improve the oil injection effect. The bearings are well lubricated. Most rolling mills now use grease lubrication. Because of the structure of vertical mill, the service life of SKF bearing in Taizhou is prolonged when the roll rotates.
Inject the specified grease or lubricant according to the requirements of the main parts of the engine.
When large bearings with large surplus products are assembled between bearings, shafts and seat holes, bearings must be heated in an oil bath at oil temperature of about 80 degrees Celsius.
When disassembling bearings, special tools must be used for drawing. It is strictly forbidden to tap bearings directly with iron tools.
During the assembly and disassembly of SKF bearings in Taizhou, the force or deformation of rollers and cages should be ***oided.
Black oxidation is a surface treatment method of bearing steel surface chemical treatment. Black oxide layer is formed when the components concerned are immersed in alkaline brine at the operating temperature of about 150 C.
The benefits of black oxide must be judged by individual applicati***, but the haza*** of such treatment remain unclear. It has been successfully applied to bearings which are difficult to operate in paper rolls, machine tools, industrial ventilators and other industries. Black oxidation process involves many parameters. The whole process c***ists of about 15 different impregnation steps. In many steps, the chemical composition, concentration, temperature, impregnation time and fluid characteristics of Taizhou SKF bearing can be adjusted.
In order to achieve good performance, black oxidation treatment is recommended for inner and outer rings. Black oxidation can be applied to major wind turbine systems of all bearing types. In recent years, cylindrical roller bearings and tapered roller bearings h***e been successfully treated and put into use.
