Abstract
A vibratory device operating as a two mass vibrating system having an exciter mass and a work member mass spring coupled and supported by isolator springs and operating at a frequency less than the natural frequency of the system. Two or more cylindrical elastomer springs are mounted on a center beam of the work member having a spring rate in the shear direction for setting the required natural frequency and also provide a spring rate in the compression direction that will have a natural frequency substantially above the natural frequency in the shear direction. The cylindrical elastomer springs mounted to a single rigid center beam provides flexibility of design for a specific work member application.

A two mass spring coupled vibrating system coupled to a work member comprising:
- a first mass comprising an exciter to produce vibratory work energy;
- a second mass having a work member including a single center beam with cylindrical elastomer springs mounted thereto, and
- wherein said cylindrical elastomer springs comprise first and second concentric cylinders encapsulating a tubular elastomer element.
A two mass spring coupled vibrating system coupled to a work member comprising:
- a first mass comprising an exciter device to produce vibratory work energy,
- a plurality of cylindrical elastomer springs, each comprising:
- a pair of concentric cylinders encapsulating a tubular elastomer element therebetween;
- said tubular elastomer element having a precompressed wall thickness greater than the radial distance between said concentric cylinders;
- each of said tubular elastomer elements being bonded to its respective concentric cylinder, and
- a second mass having a work member including a single center beam with mounting means for said cylindrical elastomer springs.
