Selection of Springs for Vibrating Sieve

The spring used on the vibrating sieve can buffer vibration and reduce the working noise, thus prolonging the service life of the vibrating sieve, so how to choose a suitable spring for the vibrating sieve?

1. Choose according to the shape

Springs can be made into products of various shapes and sizes. Its compact layout allows for useful use of space.

2. Choose according to flexibility

The elastic coefficient of rubber is much smaller than that of metal, and it changes within a large range with the change of hardness. Therefore, changing the hardness of rubber can make the spring obtain different stiffness, that is, the stiffness of the rubber spring of the same shape can also be within a certain range. selection within the range. Therefore, changing the internal layout of the spring (changing the size of the middle hole, etc.) can also change the stiffness of the spring.

3. Choose according to stiffness

 The stiffness of the vibrating sieve spring in three directions can be described according to actual needs. In addition, the rubber spring can also accept shear deformation and compression deformation together.

4.Chooseaccording to friction

The internal friction damping of the rubber spring is much larger than that of the metal spring. Therefore, when the rubber spring vibrating sieve engine passes through the resonance area, the amplitude is much smaller than that of the coil spring vibrating sieve machine. Therefore, the rubber spring near resonance vibration machine is selected. , its amplitude is relatively stable, but the energy consumption is larger than that of metal springs.

5. Choose according to resistance

The resistance of the rubber spring to transmit sound is much larger than that of the metal spring, so the sound insulation is better, and the noise during working hours is small. Because the rubber spring is made of polymer material, its ability to adapt to high and low temperature is poorer than that of the metal spring, and its stiffness is greatly affected by temperature. For the resonant rubber spring vibrating machine, the temperature change can easily lead to the deviation of the work site; in addition Rubber springs have poor oil resistance and light resistance, and are easy to age. Despite the above-mentioned shortcomings, its characteristics are outstanding, so it is still very widely used in vibrating sieve.
