Screening machine mining industry in recent years has become a star

        In the screening machine and feeder for use on rubber springs, often due to equipment vibration trajectory is a circle or a straight line, so the rubber springs

generally subject to two kinds of compression and shear deformation state. Rubber spring design is based on job requirements, need to identify various dimensions, calculate the

stiffness and strength check. So you can use gravel production line equipment from. The viscoelastic properties of the rubber, to absorb the vibration of the selected frequency

band, therefore, the spring is relatively small noise.
   
        When calculating the rubber spring stiffness, the first to determine the elastic modulus, calculated spring form factor, and then calculate the spring stiffness. When

the stone screening machine work, rubber spring work in dynamic compression deformation state, then said that the relationship between load and strain, called compression dynamic

stiffness. Rubber spring such as working at different temperature conditions, but also the rigidity value by the range of the temperature coefficient m7.
   
         Screening machine used in making rubber springs calculations, shaped to calculate the stiffness of the spring. To more accurately calculate the spring stiffness of the

vibration system, according to the vibration Circular vibrating screen direction angle to calculate the compressive deformation and shear deformation, and then calculate the

corresponding stiffness. The compressed combination of stiffness and shear stiffness vibration system to calculate the stiffness. Rubber springs still need to calculate the

compressive stress and shear stress, the compressive stress is less than the allowable stress of rubber, rubber shear stress is less than the allowable shear stress. The

composite spring is a metal coil springs and rubber spring combination, that is, the surface-treated metal coil spring outside, including a viscoelastic rubber, the composite

spring has a metal coil springs and rubber springs the advantages of both.
