Improper disassembly of SKF bearings in vibrating screens can easily lead to internal damage of the medium and coarse parts, and in severe cases, directly result in bearing scrap. Therefore, extra caution should be taken when disassembling SKF imported bearings in vibrating screens. The shaft must be supported during disassembly, otherwise the consequences can be serious for practitioners Good to learn some professional knowledge about dismantling vibrating screens.

Dismantling of SKF Bearing Peripheral for Vibration Screen

Disassemble the outer ring of the interference fit, and set several outer ring compression screws on the circumference of the shell in advance, tightening the screws evenly on one side. Dismantle on one side. These screw holes are usually covered with blind plugs, and separated bearings such as vibrating screen tapered roller bearings are used. Several notches are set on the housing shoulder. At this time, gaskets should be used, and then disassembled with a press or gently tapped to slowly disassemble.

Secondly, disassembly of cylindrical hole bearings for vibrating screens

When disassembling the inner ring, a press can actually be used to remove and pull it out It's simple. At this point, it is important to ensure that the inner ring bears its pulling force. The inner ring of the large vibrating screen bearing is disassembled using hydraulic pressure method. Oil pressure is applied through oil holes set on the shaft to facilitate pulling. SKF bearings with large widths are disassembled using both hydraulic pressure and drawing fixtures. The inner ring of the NU and NJ ring column roller vibrating screen bearings can be disassembled using induction heating method. The method of heating the local area in a short period of time to expand the inner ring and then pulling it out.

Thirdly, disassembly of tapered hole bearings

When disassembling small SKF imported bearings with fastening sleeves, it is necessary to tighten the supporting inner ring on the bearing, then turn the nut back several times and use a cushion block or hammer to knock and disassemble.

As is well known, SKF bearings have high sales, quality, and excellence Qianlie has its professional assembly line, which undergoes strict factory inspections through each process and is sold to Everywhere, for Provide support for industrial development. The quality of SKF imported bearings has won market recognition What are the important criteria for determining the quality of SKF imported bearings?

Firstly, the industrial design of bearings is reasonable have.... Level, strong quality Over its lifespan. SKF bearing forging requires strict processes such as forging, bearing heat treatment, turning, grinding, and bearing equipment, all of which can affect the service life of the bearing. The impact on the quality of imported SKF bearings is directly related to bearing failure. With the continuous progress of technology testing, it has been found that the grinding process of the deteriorated layer is closely related to the quality of the SKF bearing surface.

Secondly, the metal lottery used in SKF bearing manufacturing was once a major factor affecting bearing failure. With the continuous advancement of metallurgical technology, the extraction of raw materials has been greatly improved, and the quality of materials has also been greatly improved. The quality factor of raw materials has significantly decreased in bearing failure, and this problem still exists at this stage.

Thirdly, whether the material selection for bearing manufacturing is qualified is also a factor that must be considered for bearing failure. In the usual detection of SKF bearing failure, it is mainly based on a large amount of Beijing materials, data analysis, failure environment, forging process, to identify the main factors of bearing failure and solve them, which facilitates the continuous optimization, service life, and efficiency improvement of SKF bearings. Extend the service life of SKF bearings to avoid sudden early failure of bearings. Installation conditions are one of the primary factors in the use of SKF bearings. Improper installation often leads to changes in the stress state between the various parts of the entire bearing system, causing SKF bearings to operate abnormally and fail prematurely. According to the technical requirements for SKF bearing installation, use, maintenance, and upkeep, monitor and inspect the load, speed, working temperature, vibration, noise, and lubrication conditions of the bearings during operation. If any abnormalities are found, immediately identify the cause and make adjustments to restore them to normal.
