Composite spring used in practice: the generally used as vibration damping device screen, also known as steel rubber damping spring, played a very good shock absorption, cushioning effect. Here is the actual application diagram: composite spring composite spring is made of metal coil springs and rubber composite with cylindrical elastomer. The product has good corrosion resistance, long life and other advantages, compared with other metal springs, damping ability, good cushioning effect, noise. Note: 1, according to a single piece of stiffness KL (kg / cm) as a basis for acceptance of production, which allows 15% deviation. 2, to indicate the selection of models, stiffness, and indicate the number of each, easy to use experimental groups, in order to facilitate the installation. ◆ composite spring Technical Data Sheet Model Specifications D × H × d (mm) outer diameter D (mm) inner diameter d (mm) Free height H (mm) Working deformation of FV (cm) stiffness KL (kg / cm) to allow load Pa (kg) JHF-90 × 150 Φ90 × 150 × Φ40 90 40 150 2 150 700 JHF-150 × 265 Φ150 × 265 × Φ80 150 80 265 3 180 1000 JHF-150 × 265 Φ150 × 265 × Φ80 150 80 265 3 200 1200 JHF-150 × 265 Φ150 × 265 × Φ80 150 80 265 3 250 1500 JHF-150 × 265 Φ150 × 265 × Φ80 150 80 265 3 350 2000 JHF-155 × 290 Φ155 × 290 × Φ60 155 60 290 3 240 1500 JHF-155 × 290 Φ155 × 290 × Φ60 155 60 290 3 270 1700 spring rubber spring rubber is a polymer elastomer, using pure natural rubber, the damping effect of the product is good, small resonance field, long life, low cost, and good cold resistance, excellent air tightness, water resistance, electrical insulation, is the best choice for damping. Rubber springs used in practice: the generally used as vibration damping device screen, also known as rubber damping spring, can also be used for feeder hanging device, play a very good shock absorption, cushioning effect.
