Damping spring is common elastic component, and
it is widely applied in varies of vibration equipment. Damping spring has many
advantages, such as good stability, low noise, good damping effect, long
lifespan. Usually, the isolation spring has three types, wire spring, rubber
spring and complex-spring.
Vibrating screens major components include screen
box, vibrating motor, isolation spring. The isolation spring plays an important
role in the design of vibrating screen. The isolation can be customized by
different material according to different vibrating screen. The specific data
needs to be defined by the screening material. The isolation spring main
material includes: rubber, metal, cork, felt, etc.
1. The spring design should choice the proper
material of spring according to screening materials, environment condition and
the proportion of material itself.
2. Must need to notice the bonding degree between
the rubber and metal, to avoid bonding surface stress concentration.
3. In order to improve the lifespan of isolation
machine, we advice to provide some appropriate pre-compression in the vertical
shear direction, compression direction rigidity harden and direction of shear rigidity
becomes soft;
4. The rubber is bad conductor, in order to
prevent the temperature rise over-top thus impact the performance of rubber
damper, the rubber damper is not suitable for producing too large, and it
is suitable for easy to heat dissipation device, or choose the natural rubber.
Just because the rubber damper can change the energy into heat energy, it
reduce the vibrating energy, reached the purpose of reducing vibration, so we
usually take the rubber damper as the vibration damper.
5. Scheduled
maintain and replace the isolation spring, the damper should avoid working in
the tensile state.
