Cylinder Rubber Air Bellow

1.The Air Bellow Description

It is a precision-designed rubber fiber corrugated tube. It does not provide force or support load by itself, but uses compressed air to fill the inside of the air compressor to achieve force. Transfer and elastic effect.

According to the requirements of the stroke, the air spring is generally designed to be 1-3, and it can also be designed and manufactured to be 4 or more than 5 when needed. Under certain conditions, the air spring can also be superimposed.

Air springs have non-linear characteristics, and their stiffness changes with load, so their natural vibration frequency is almost unchanged under any load, so that the spring device has almost constant characteristics, and it has a good ability to absorb high frequency vibration and sound insulation.

It can bear axial load and radial load at the same time. Through internal pressure adjustment, it can also get different bearing capacity. Therefore, it can be applied to various load requirements.

During the effective stroke of the air spring, the stiffness, height, cavity volume, and bearing capacity of the air spring are adjusted by increasing or decreasing the inflation pressure.

At the same time, its stiffness, height, cavity internal volume, and bearing capacity will change smoothly and periodically with the increase and decrease of the load, thereby achieving flexible transmission of bearing capacity, effective adjustment of stroke, and vibration amplitude and vibration load. Efficient control. An air chamber can also be added for automatic adjustment.

3.The Air Bellow Characteristics

(1) the stiffness of the rubber air spring changes with the load, which makes the spring device have an ideal characteristic.
(2) the rubber air spring has nonlinear characteristics, and its characteristic curve can be designed to be ideal shape and can bear axial and radial loads simultaneously, and it can also transfer torque.
(3) the rubber air spring can get different bearing capacity by adjusting the internal pressure, so it adapts to the demand of various loads.
(4) the weight of the rubber air spring is light and the service life is long.
(5) the high frequency vibration isolation and sound insulation performance of the rubber air spring is good. The installation space of rubber air spring is small and the replacement is convenient.

4.The Air Bellow Working Principle

When the rubber air spring works, the inner cavity is filled with compressed air to form a compressed air column.With the increase of vibration load, the height of the spring decreases, the volume of the inner cavity decreases, the stiffness of the spring increases, the effective bearing area of the inner air column increases, and the bearing capacity of the spring increases.When the vibration load decreases, the height of the spring increases, the volume of the inner cavity increases, the stiffness of the spring decreases, the effective bearing area of the inner air column decreases, and the bearing capacity of the spring decreases.In this way, during the effective stroke of the air spring, the height of the air spring, the volume of the inner cavity and the carrying capacity increase with the increase and decrease of the vibration load.In addition, the stiffness and bearing capacity of the spring can be adjusted by the method of increasing and reducing the amount of gas, and the auxiliary gas chamber can be attached to realize self control and adjustment.
