METHOD OF MANUFACTURE OF ELASTOFRICTIONAL MEMBERS OF CABLE VIBRATION ISOLATORS Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used in manufacture of cable vibration isolators designed for protection of equipment and instruments from shocks and vibration in any sphere of application. According to proposed method, elastic member is made of multicore outer strand of standard preliminarily untwisted cable with screw elastic line. Strand is curved to form ring with mean diameter equal to required length of elastic member. Then strand is wound onto said ring in multiple layers so that coils of free ring of screw strand are equidistant to first and subsequent layers until screw space of closed contour in form of Moebius torus is filled up completely. Elastic member in form of closed contour or Moebius torus is made with mean diameter D to formulas or where t is pitch of screw line of outer strand of used cable; n is number of periods of strand screw line. Invention makes it possible to manufacture shock absorbers featuring stable elastodamping characteristics in operation. EFFECT: simplified technology of manufacture, provision of minimum wear of shock absorbers. 3 cl, 10 dwg
