KOYO Bearing Application

wallpapers Industry 2020-12-23

There are many types of metallurgical equipment, not only the equipment required by the raw material factory, but also the equipment required from the upstream process to the downstream process (such as steelmaking process, rolling process and straightening process).
These devices are equipped with various bearings. These bearings are used under the unique "iron powder", "water" and "hot" conditions of metallurgical equipment, and must also meet the conditions of "heavy load + vibration and shock", "from ultra-low speed to high speed + rapid acceleration and deceleration". It is used under very harsh conditions. "
"Stable operation and improved production efficiency" can be said to be the proposition of the representative industry in the field of metallurgical equipment. KOYO aims at this proposition. It not only promotes the development of bearing design technology, but also starts from the development of bearing material technology, lubrication technology, analysis technology and other inherent perspectives, and promotes corresponding measures and research and development work every day.
According to the main criteria of the bearing capacity, the material used to make the bearing should have a certain load-bearing capacity, embeddedness, thermal conductivity, low friction coefficient, smooth surface, anti-wear, anti-fatigue and anti-corrosion. No single material can fully meet all requirements, which is why compromise is often used in most designs.
Bronze bearings are suitable for low-speed and heavy-duty applications with good shaft and bearing alignment. They can be made of various alloy components to obtain various physical properties.
Lead copper
The bearing capacity of this kind of bearing is higher than that of the bearing alloy, and its adaptability is poor, so it is used in occasions with good shaft rigidity and good centering.
Cast iron
Cast iron bearing materials are widely used in occasions with less stringent requirements. The hardness of the journal must be higher than the hardness of the bearing bush. The work surface should be carefully run-in with a mixture of graphite and oil. It is required that the journal and the bearing must be well aligned.
