    The elastic elements used in the vibration screening equipment can be divided into three categories according to their purposes: 1 Main vibration spring: its function is to make the vibration machinery work in the specified working state (entering the resonance state) For example, the vibration motor and some other resonance machinery usually use the working state of near sub resonance with the forced frequency slightly lower than the natural frequency, At this time, the main vibration spring must be used 2 Vibration isolation spring: its function is to realize elastic support for the vibration machine body, to generate elastic vibration of the machine body, and to reduce the dynamic load transmitted to the foundation or the structural frame 3 Other special purpose springs, such as guide plate spring and connecting rod spring, etc currently, there are many structural forms of spring used in the vibration machine, In many vibrating machines, the plate spring is used as the guide rod, and as the main vibration spring in the plate spring electric vibration feeder and vibration conveyor In some vibrating screens, the plate spring bent into a circular arc is used as the vibration isolation spring The advantages of the plate spring are: the total stiffness of the spring can be adjusted by increasing or decreasing the number of springs, It can make the machine body realize directional vibration The disadvantages are large processing amount, strict manufacturing process requirements and large space occupied 2 Spiral spring: circular section cylindrical spiral spring is one of the elastic elements widely used in vibration machinery at present Its advantages are convenient manufacturing, small internal friction, economic energy consumption and strong life under the correct design; The disadvantages are large volume, easy to produce noise, inconvenient to adjust its stiffness, small lateral stiffness, easy to make the body sway laterally 3 Rubber spring: in vibration machinery, rubber spring has been widely used, it can be used as the main vibration spring, as well as the vibration isolation spring and transmission spring, which can work under air pressure, You can also work in shear
