Why is rubber spring an indispensable part of vibration equipment?

The internal friction resistance of the rubber spring is much larger than that of the wire spring. Therefore, when the vibrating screen machine using rubber spring starts to pass through the resonance zone, the amplitude is much smaller than that of the spiral spring vibrating screen machine. , Its amplitude is relatively stable, but the energy consumption is greater than that of a wire spring.

The resistance of the rubber spring to transmit sound is much greater than that of the wire spring, so the sound insulation is better, and the noise is relatively small when working.

Since rubber springs are made of polymer materials, they are less able to adapt to high and low temperatures than steel wire springs, and their stiffness is more affected by temperature. For resonant rubber spring vibrators, temperature changes can easily cause deviations in the work site; in addition, rubber The spring has poor oil resistance and light resistance, and is prone to aging.

The rubber springs to be used in the vibrating screen can be made into products of various shapes and sizes. This can make the structure more compact and more efficient use of space.

Because the coefficient of elasticity of rubber is much smaller than that of metal, and changes in a larger range with the change of hardness, changing the hardness of rubber can make springs have different stiffness, that is, rubber springs of the same shape can have a certain stiffness. Select within the range. There are also changes in the internal structure of the spring (such as changing the size of the center hole, etc.), and the stiffness of the spring can also be changed.

The stiffness of the vibrating screen rubber spring in three directions can be designed according to actual needs. In addition, the rubber spring can also withstand shear deformation and compression deformation at the same time.
