Do you know the characteristics and applications of spherical bearings?

Jul 24, 2024

Spherical bearings, as a kind of spherical sliding bearing, play a vital role in many industries because of their unique structure and performance characteristics. Its structure mainly includes an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. It can rotate and swing at any angle and adapt to complex and changeable working conditions.

1. Characteristics of spherical bearings

Spherical bearings have a number of distinctive characteristics that give them unique advantages in a variety of applications. First of all, spherical bearings can withstand large loads, including radial load, axial load, or combined radial and axial loads at the same time. Secondly, spherical plain bearings have excellent impact resistance, corrosion resistance, and wear resistance, thanks to their special processing methods and structural design. In addition, spherical plain bearings also have the characteristics of self-aligning and good lubrication and can automatically adjust axis deviation during work to reduce friction and wear.

2. Application of spherical plain bearings in engineering machinery

Telescopic arms and turntables

In construction machinery, telescopic arms and turntables are key components that bear compound loads. Spherical bearings play an important role in these components, being able to withstand large radial loads and tilting moments and allowing free end rotation. For example, on excavators, spherical bearings are used on the tipping bucket to bear compound loads and achieve 360-degree unlimited rotation. This design enables the excavator to operate flexibly in complex working environments and improve work efficiency.

Buckets and breakers

Buckets and breakers are commonly used working devices in construction machinery. They need to withstand huge impact and vibration during work. The application of spherical bearings in these components can reduce friction and losses in the transmission system and extend the service life of the machinery. At the same time, the self-aligning characteristics of the spherical bearings enable these components to automatically adjust their axis deviation when impacted and maintain stable working conditions.

3. Application of spherical bearings in automation equipment

Robots and production lines

In the automation industry, spherical bearings are mainly used for rotational support of equipment that requires adjustable angles, such as robots and production lines. For example, on a production line, goods need to be frequently transferred from one location to another. In this case, spherical bearings are needed to support the rotation to complete the transfer of goods conveniently and quickly. The high precision and stability of spherical plain bearings enable automated equipment to achieve efficient and accurate motion control.

Robots and conveyor belts

In automated production lines and equipment, robots and conveyor belts are common actuators. The application of spherical bearings in these components can ensure their stable operation under high-speed and high-precision movement requirements. At the same time, the good lubrication characteristics of spherical bearings enable these components to maintain good performance during long-term operation.

4. Application of spherical bearings in automobile shock absorbers

Shock absorbers are an important part of the automobile suspension system. They can absorb and disperse vibrations caused by uneven road surfaces and improve driving comfort and stability. As one of the main components of the shock absorber, the spherical bearing can balance the weight of the vehicle's body and reduce the danger caused by an unstable center of gravity when the vehicle is driving. Especially when driving at high speed or turning, the role of spherical bearings is more obvious. In addition, the self-lubricating characteristics of the spherical bearing enable the shock absorber to maintain good performance during long-term operation.

5. Application of spherical plain bearings in other industries

In addition to the above fields, spherical plain bearings are also widely used in engineering hydraulic cylinders, forging machine tools, water conservancy machinery, and other industries. In these industries, spherical plain bearings play an irreplaceable role with their unique performance characteristics. For example, in engineering hydraulic cylinders, spherical bearings can withstand the huge force generated by the cylinder under high pressure, ensuring the stable operation of the cylinder; in forging machine tools, spherical bearings are used to support and guide large workpieces to ensure their accuracy during processing. Location and stability.

To sum up, spherical plain bearings play an important role in many industry fields. Its unique structure and performance characteristics enable it to adapt to complex and changing working conditions and demonstrate superior performance in various applications. With the continuous development of science, technology, and industry, the application fields of spherical bearings will become more extensive, and their position in industrial production will become more important.
