For the industrial applications involving heavy CNC machines and power presses, there is a requirement of anti-vibration mounting pads that can take large loads and also provide leveling adjustment. The most suitable vibration pads for machinesare the wedge mounts. The three-piece wedge mount comprises of a center wedge that can slide between the top and bottom wedge. The movement of the center wedge is controlled by an adjustable bolt which is mounted parallel to the ground or base. Depending on the weight and size of the machine it is possible to select the suitable wedge mount.
Wedge mount as a suitable anti-vibration isolation pad: At the bottom of the wedge mount is the typical insulation plate which is made from elastomers. The vibration damping capabilities of the wedge type anti-vibration isolation pads come from these elastomeric insulation plates. It is possible to customize them according to the damping frequency requirement. The leveling of the CNC machine or the power press can be obtained by the movement of the center wedge through the adjustable bolt. The sliding wedge ensures precision height adjustment. The supporting surfaces of the wedge type vibration damper pads are so large that they are not only rigid but provide solidity as well. The typical application of the wedge mounts are suited for the machines that require:
- Free placement
- Bolting to the anti-vibration isolation pads
- Grouting to the floor in addition to bolting
- Precision leveling
- More than normal height adjustment
Rubber anti-vibration pads: The machines that generate high-frequency vibrations require the use of anti-vibration sheets and rubber anti-vibration pads. The examples of high frequency generating machines are compressors, conveyors, diesel generators, fans, motors, and pumps. The wide range of vibration absorbing pads is suitable for reducing and damping the vibrations caused by air-conditioning and refrigeration plants and many other similar applications. Besides the industrial applications, the vibration absorbing pad is suitable for domestic applications also.
When the prime consideration is the damping of vibration the anti-vibration pads provide the ideal solution. They are very stable under the compressive load and are suited for applications like HVAC systems, heavy compressors, computer systems, laboratory and inspection equipment, movie halls and theaters etc. The anti-vibration pads have a sandwich construction, where a fluted elastomer element is set between two rubber cork pads. While the cork layer is responsible for providing a high-friction surface, the fluted elastomer takes care of vibration damping. The selection of the anti-vibration pads can be made based on the load conditions.
Neoprene isolation pads: The Neoprene elastomer is oil and water resistant and the neoprene padsare designed to operate within the strain limits of the isolator. This gives the neoprene pads a long life expectancy. The construction available is single and double ribbed type and also alternate high and low ribs for maximum deflection.
