Rubber shock pad
Rubber shock pad used in punch, ball mill, cutting plate machine, printing machinery, and instrument table passive vibration isolation.
Product number | Load capacity | The corresponding vertical unit under the rated load deformation（mm） | The corresponding vertical unit under the stable load of the natural frequency（HZ) | Vertical unit limit static load（kg/cm2) | Operating temperature range（℃） | Damping ratio （C/Cc） |

1, the standard cushion pad area of 24 * 46 c ㎡, connecting the four central area of 1c㎡
2, according to the weight of the equipment and work to determine the cushion pad area, in the standard pad on the cut
Cushioning area = equipment weight ÷ selected cushioning capacity of the cushion
On the impact and increase the equipment, but also consider the overweight factor
Example: a device weight 3500 kg, the fulcrum shape Φ12 six round panels, because the equipment on the level of higher requirements, the choice of WJ-85
Taking into account the vibration of the equipment and work, the calculation of the appropriate increase in the weight of about 30% of the equipment.
Bearing area = (3500 * 1.3) /7 kg c ㎡ = 650 c ㎡
Unit support area = 650 c ㎡ / 6
Cushion pad in the support below to reveal 1 cm margin, so the pad cut into
12 * 12 c ㎡
