Claims
- 1. A vibration damping roll having an axle assembly disposed on a longitudinal axis for said roll, an outer shell coupled to said axle assembly for rolling contact with a vibrating structure and a mechanical wave guide fixed to at least one of said shell and said axle assembly the wave guide consisting of radially alternating rigid and flexible material having at least one rigid element disposed adjacent to flexible material, the wave guide being designed to operate over a range of vibration frequencies.
- 2. A vibration damping roll according to claim 1 in which the outer shell is made of metal.
- 3. A vibration damping roll according to claim 1 in which the flexible material is made of synthetic plastic.
- 4. A vibration damping roll according to claim 1 in which said at least one rigid element is made of metal.
- 5. A vibration damping roll according to claim 1 in which the wave guide consists of several alternating layers of rigid material and flexible material.
- 6. A vibration damping roll according to claim 1 in which the alternating layers are concentric with said axle assembly.
- 7. A vibration damping roll according to claim 1 in which the wave guide extends along substantially the entire length of the roll.
- 8. A vibration damping roll according to claim 1 having at least two wave guides longitudinally spaced from each other on said axle assembly.
- 9. A vibration damping roll according to claim 1 having two wave guides disposed at respective opposite ends of the damping roll.
- 10. A vibration damping roll according to claim 1 having a plurality of wave guides angularly spaced about said axle assembly.
- 11. A vibration damping roll according to claim 1 having four wave guides which are orthogonal to each other about said axle assembly.
- 12. A vibration damping roll according to claim 1 in which the wave guide consists of a plurality of metal spheres dispersed in a matrix of synthetic plastic material.
- 13. A vibration damping roll according to claim 1 in which the wave guide consists of a spiral shaped rigid element disposed in a matrix of flexible material.
- 14. A vibration damping roll according to claim 1 in which the wave guide consists of at least two layers of rigid material interspaced with flexible material.
- 15. A vibration damping roll according to claim 14 in which the mass of radially outer rigid elements is greater than the mass of radially inner rigid elements.
- 16. A vibration damping roll according to claim 1 in which the rigid elements are selected from a material having a low stiffness to mass ratio.
- 18. A vibration damping roll having an outer shell for rolling contact with a vibrating structure and a mechanical wave guide fixed to said shell and the wave guide consisting of radially alternating rigid and flexible material having at least one rigid element disposed adjacent to flexible material, the wave guide being designed to operate over a range of vibration frequencies.
- 19. A vibration damping roll having an axle assembly disposed on a longitudinal axle for said roll coupled to said axle assembly for rolling contact with a vibrating structure and a mechanical wave guide fixed to said axle assembly, the wave guide consisting of radially alternating rigid and flexible material having at least one rigid element disposed adjacent to flexible material, the wave guide being designed to operate over a range of vibration frequencies.
