How it works
The best shock absorber should be the air spring. The rubber air spring has the advantages of high frequency isolation, sound insulation and low self-vibration frequency, which can better achieve vibration isolation and ensure the safety and stability of the base of the vibration equipment and the control system. . Therefore, the rubber air springs introduced by Gaomaat air spring manufacturers are widely used in equipment shock absorption equipment.
After the rubber air spring is assembled into an assembly, the compressed air is filled into the air spring, and the compressibility of the air is used to realize the elastic effect. The air spring has nonlinear characteristics, and its characteristic line can be designed into an ideal curve according to the needs; the stiffness of the rubber air spring changes with the load, so that the spring device has ideal characteristics: the rubber air spring can withstand the axial and radial direction at the same time. It can also transmit torque to the load.
The rubber air spring can obtain different bearing capacities by adjusting the internal pressure, so it can meet the needs of various loads: the rubber air spring is light in weight and has a long service life; the rubber air spring has good high-frequency vibration isolation and sound insulation performance. The rubber air spring requires little installation space and is easy to replace.
