 Damping Spring for kelly bar

      Damping spring is for kelly bar accessories,it assumes spiral-shaped,the elasticity is strong ,each different specification of spring is suitable for different type of kelly bar.

    A spring is a mechanical part that works with elasticity. Generally made of spring steel. It is used to control the movement of mechanical parts, mitigate impact or vibration, store energy, measure the force, etc. it is widely used in machines and meters.

   The spring is only an energy accumulator. It has the function of storing energy, but it cannot release the energy slowly. To realize the function of slowly releasing, it should be realized by "Spring + large transmission ratio mechanism", which is common in mechanical watches.

    Spring is an elastic element widely used in the mechanical and electronic industries. When loaded, the spring can produce large elastic deformation and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to the original state, and the deformation energy is converted into mechanical work or kinetic energy.
