Rubber springs

Rubber spring is a kind of high elastomer, made of ordinary rubber, using rubber elasticity to cushion, shock absorption spring. Rubber springs have much greater internal friction resistance than steel wire springs, so when a vibrating screen machine using a rubber spring starts through the resonance zone, the amplitude is much smaller than that of a coil spring vibrating screen machine. The resonance vibrating machine using rubber spring has a relatively stable amplitude, but the energy consumption is greater than that of steel wire spring. Therefore, rubber springs are indispensable in vibration equipment for the following reasons:

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

2. The 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 make better use of space.

3. Because the elastic coefficient of rubber is far smaller than that of metal, and changes in a larger range with the change of hardness, changing the hardness of rubber can make the spring obtain different stiffness, that is, the same shape of rubber spring, its stiffness can also be selected within the *** range. It is also possible to change the stiffness of the spring by changing the internal structure of the spring (such as changing the size of its center hole, etc.).

4. The stiffness of the vibrating screen rubber spring in three directions can be designed according to the actual required size. In addition, rubber springs can withstand both shear and compression set

Comparison of the advantages and disadvantages of rubber springs

First, the advantages of rubber springs

1. The rubber spring has a relatively high internal resistance, which has a good function for sudden impact or high-frequency vibration absorption and sound insulation;

2. The shape of the rubber spring is uncontrolled, and the stiffness of all directions can be selected according to the actual situation, and there is no unified standard;

3. The rubber spring can bear the load in multiple directions at the same time, and the same rubber spring can also bear it, which simplifies the structure of the system;

4. The elastic modulus of the rubber spring is relatively small, but the elastic deformation obtained is relatively large, and it is easy to achieve nonlinear characteristics and achieve the ideal state;

5. The installation and disassembly of rubber springs are more convenient and easy to maintain;

6. During use, the rubber spring does not need lubrication, which is convenient and fast.

Second, the disadvantages of rubber springs

1. Because the rubber spring is not a pure elastomer, but a relatively viscous elastic material, its mechanical properties **** are more complicated;

2. Compared with steel springs, rubber springs have poor high temperature resistance, low temperature resistance and oil resistance, so they should be selected according to the actual situation;

3. The shape of the rubber springs used in the production process is simpler than that of bellows, but it is more difficult to calculate their elastic characteristics.
