Definitions

  • the plies are aligned such that the intermediate ply, which in the preferred embodiment is elastomeric core, is installed between the first ply and the second ply.
  • the sandwich arrangement is created.
  • a conventional bellows forming machinery is used to simultaneously form convolutions in the three aligned members .
  • a further step in the method of forming the sandwich bellows construction is to join the ends of the first and second ply as discussed above. While joining the ends of the first and second plies, the intermediate ply is aligned therebetween such that a gap is formed between the ends of the intermediate ply and the ends of the first and second plies.
  • the sandwich bellows construction of the present invention can be formed with diameters ranging from 1 inch to 200 inches.
  • the first and second plies are preferably metallic in structure. These metallic plies have a thickness in the range of 10 to 100 millionths of an inch.
  • the intermediate ply is an elastomeric member. This elastomeric member is usually provided with a thickness in the range of 10 to 250 millionths of an inch.

Abstract

Cette invention concerne une construction de soufflet en sandwich constituée d'éléments présentant trois épaisseurs. Dans une réalisation préférée de l'invention, les épaisseurs externes sont en métal, tandis que l'épaisseur interne est composée d'un élastomère. Dans une réalisation préférée de l'invention, les extrémités des épaisseurs externes et interne sont rassemblées de manière à ce que l'élément de couche intermédiaire soit enfermé hermétiquement entre les deux autres. Dans une autre réalisation de l'invention, la construction de soufflet en sandwich comporte une pluralité de circonvolutions. Cette dernière réalisation de la construction de soufflet en sandwich permet de disposer d'un soufflet continu, étanche, à circonvolutions qui constitue un agencement de soufflet faisant office d'amortisseur efficace des vibrations.
