Understand the structural design and principle of shock absorber bearings?

Shock absorber bearing is a device used to reduce mechanical vibration and noise, which is usually composed of a jacket, an inner core, a shock absorber medium and a variety of sealing structures, with good shock absorption effect and long-term stability. Let's take a closer look at the structural design and working principle of shock absorber bearings.

First, structural design

1. Jacket: The shell of the shock absorber bearing is usually made of metal or rubber and other materials, and the design of the shell should take into account the ability to withstand external loads and environmental impacts, while also having a certain degree of tightness and corrosion resistance.

2. Inner core: The inner core is the core part of the shock absorber bearing, usually made of metal, rubber or spring materials, the design of the inner core should take into account the shock absorption effect, carrying capacity and stability, but also be able to adapt to different working conditions and environments.

3. Shock absorbing medium: The shock absorbing medium of the shock absorber bearing is usually made of gas, liquid or solid materials, and the design of the shock absorbing medium should take into account its compressibility, elastic modulus and wear resistance characteristics to ensure good shock absorbing effect and reliable service life.

4. Sealing structure: The sealing structure of the shock absorber bearing usually uses rubber rings, sealing rings or dust jackets and other components to prevent dust, water vapor and other impurities from entering the shock absorber, thereby affecting its normal work.

Second, the working principle

The working principle of the shock absorber bearing is mainly based on the elastic deformation and energy absorption characteristics of its internal shock absorber medium. Under the action of mechanical shock and shock load, the shock absorber bearing can effectively absorb and disperse energy through the deformation and flow of its internal medium, thus reducing the vibration transmission and noise generation, and protecting the normal operation of mechanical equipment and systems.

Specifically, when the mechanical system is shaken or impacted, the internal medium of the shock absorber bearing will be compressed or shear by the force, resulting in strain deformation, converting energy into internal deformation energy and heat energy, and gradually released. Under the action of shock absorbing medium, the vibration energy will be absorbed and transmitted through the shock absorber bearing, and finally lead to the reduction of the vibration amplitude and frequency, so as to achieve the purpose of shock absorbing and protecting the mechanical system.

In general, the structural design and working principle of shock absorber bearings is to improve the operating stability of mechanical equipment, reduce noise and vibration, and extend the service life of equipment, which is an indispensable part of modern engineering technology. Through continuous optimization and innovation, shock absorber bearings will play an increasingly important role in various engineering applications.
