Isolation system for vibratory equipment

A vibration isolation component for connecting a vibrating structure to a relatively non-vibrating structure comprising:

• a spring having a first end and a second end, said spring being compressible and expandable along an axis between said first and second ends, said spring arranged to support the vibrating structure from the non-vibrating structure;
• a damper element;
• wherein said damper element comprises an elastomer ring;
• a housing surrounding said spring and said damper element and including a first wall adjacent to said second end of said spring, and said damper element is arranged adjacent said first end, and said housing comprises a second wall opposite said first wall, said damper element braced against said second wall, expansion of said spring being opposed by compression of said damper element;
• a connector which is connected to said first end of said spring and extending past said first wall, said connector moving in a direction from said first end toward said second end to compress said spring under load;
• and
• wherein said first wall comprises a weight sized to lower the natural frequency of the horizontal bending mode of the component such that said natural frequency is substantially unequal to the operating frequency of the vibratory equipment held by the component.

• a spring having a first end and a second end, said spring being compressible and expandable along an axis between said first and second ends, said spring arranged to support the vibrating structure from the non-vibrating structure;
• a damper element having a cylindrical configuration and arranged surrounding said spring with a radial clearance therebetween and arranged to impart a resilient force against contraction of said spring;
• and
• wherein said damper element and said spring are supported from said non-vibrating structure on bottom ends thereof, and comprising an elongate member connectable to the vibrating structure, and a compression washer, said elongate member connected to said compression washer, said compression washer located above and against top ends of said spring and said damper element, downward force on said elongate member acting to compress said spring and said damper element.

A vibration isolation component for supporting a vibrating structure comprising:

• an isolation spring having a bottom end and a top end adapted to support a vibrating structure, and having a spring resiliency between said bottom end and said top end;
• a damper element arranged between said external support structure and the vibrating structure to impart a resilient force against movement between said bottom end and said top end;
• and
• wherein said isolation spring comprises a coil spring and said damper element comprises a cylindrical elastomeric element surrounding said coil spring with an annular gap between an outside of said coil spring and an inside of said elastomeric element;
• and said component comprises an elongate member and a compression washer, said elongate member connected to said compression washer at a first end and connectable to the vibrating structure at a second end thereof, said compression washer overlying said coil spring on said top end of said coil spring, and a frame supportable from external support structure;
• and said coil spring arranged to be supported by said frame on said bottom end of said coil spring, said coil spring and said elastomeric element compressed by a downward load on said elongate member via said compression washer, said elastomeric element arranged between said top end of said coil spring and said frame to inhibit movement of said top end of said coil spring.
