The compact wire rope isolator unleashed!

The electronic components fitted in machines and panels are very precise and sensitive in nature. When the electronic equipment runs, there are parts that produce the hum and vibrations which can cause serious damage to the surrounding components. The first

requirement of the vibration damping needs was met with the elastomer pads. However, the rubber vibration mounts were unable to perform due to temperature variations. Despite having heat dissipation devices installed the electronic components get heated to high temperatures.  The vibration pad was ineffective in the concurrent shock and vibration application. The fans used for cooling the electronic devices were also producing vibrations. The anti-vibration mount wire rope isolators were too big for the electronic applications and hence an alternative was worked out. That is when the circular cable isolators were born. The characteristics: The circular cable isolators have a homogenous design and a single point installation. Thus, they provide multi-axis isolation which is quite consistent. Given the small size, the compact wire rope isolator is well suited for the separation of key fundamental components rather than the complete system. Not only are the compact

isolators economical but also are suitable for high-performance design systems. As far as the maximum dynamic displacement is concerned, it utilises 70 per cent of the space taken up by the circular cable isolators. The dynamic stiffness decreases with the increase in displacement. The resilience is shown by the cable isolator in the case of a shock loading. Due to the impact loading the shock isolator does buckle but does not get permanently deformed. It is able to spring back into position once the shock load is removed. The construction: The cable isolators are made up of stainless steel 304 grade wire rope and suitable aluminium alloy retaining bars with T6 heat treatment. The strands of high tensile steel wire are interwoven to construct the vibration isolation wire rope. The

construction gives the circular cable isolators the desired strength to withstand the shock load and depict resilience. The metallic constituents are unaffected by ozone, chemicals and oils. This is because of the basic inert nature of the raw material used in the construction. In fact, the circular cable isolators can withstand environmentally unfriendly and harsh requirement also.  They also withstand extreme temperatures from -100oC and going up to 250oC. The temperature range covers the majority of applications in the industry today. The load capacity is from 5 to 35 KGs and well suited to the electronic industry. The products also conform to a number of military standards and industry specifications. Additional features: The circular cable isolators depict non-linear attributes in the stiffness characteristics. As compared to the larger shock deflections, the smaller deviations are normally linked with vibration damping which has a different spring rate. The cable isolator’s vibration damping is to the tune of 5 to 15% depending on the size and input level. Since, the compact wire rope isolator is capable of operating on more than one axis; it can withstand compression load, 45o compression load as well as the shear load very easily. The versatility of the design allows the compact wire rope isolators to be used in a number of applications. In the electronic industry, they used for CD-ROM drives and disk drives. These devices have rotating parts which generate vibrations and humming noise. The equipment like centrifuges and medical ventilators make use of the compact design. The varying load and speeds of rotation are well absorbed by the anti-vibration mount wire rope isolators. Then, there are a variety of applications like avionics, sound systems, video displays, audio-visual combinations, small motors and pumps, sensitive lab equipment and electronic devices where the circular wire isolators are deployed. People buy wire rope isolators as they are a versatile piece of equipment offering vibration and shock mitigation solutions.
