Rubber spring is a kind of high elastic body, which is made of ordinary rubber, which uses rubber elasticity to cushion and shock. The friction resistance of rubber spring is much larger than that of steel wire spring. Therefore, when the vibrating screen machine with rubber spring is used to start through the resonance zone, the amplitude appears much smaller than that of spiral spring vibrating screen. The vibration amplitude of the resonant vibration machine with rubber spring is stable, but the energy consumption is larger than that of the steel wire spring. Therefore, the rubber spring is an indispensable reason in vibration equipment, which includes the following points:

1. Rubber spring has more resistance to transmit sound than steel wire spring, so sound insulation is better and relatively noise is small when working.

2. The spring to be used in the shaker can be made into various shapes and sizes of products. This makes the structure more compact and more space available.

3. Because the elastic coefficient of rubber is much smaller than that of metal and changes in a large range with the change of hardness, changing the rubber hardness can make the spring obtain different rigidity, that is, the same shape of rubber spring, its rigidity can also be selected within * * * range. The internal structure of the spring (such as changing the size of the core hole) can also change the stiffness of the spring.

4. The stiffness of the rubber spring in three directions of the shaker can be designed according to the actual size. In addition, rubber spring can bear both shear and compression deformation

Comparison of advantages and disadvantages of rubber spring

1、 Advantages of rubber spring

1. rubber spring has relatively high internal resistance, which has good function for absorption and sound insulation of sudden shock or high frequency vibration;

2. the shape of rubber spring is uncontrolled, and the stiffness of each direction can be selected according to the actual situation, and there is no uniform standard;

3. rubber spring can bear multi-directional load at the same time, and the same rubber spring can bear it, thus simplifying the structure of the system;

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

5. the installation and disassembly of rubber spring is convenient and convenient for maintenance;

6. during the use, the rubber spring does not need lubrication, which is convenient and quick.

2、 The shortcomings of rubber spring

1. because rubber spring is not a pure elastic body, but belongs to a kind of viscoelastic material, its mechanical properties * * * are more complex;

2. compared with steel spring, rubber spring has poor resistance to high temperature, low temperature and oil resistance, so it is necessary to choose according to the actual situation;

3. the shape of rubber spring used in the production process is simpler than that of bellows, but it is difficult to calculate their elastic properties.
