VIBRATION ISOLATION SUPPORT FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: vibration isolation support for internal combustion engine has flexible member made in form of closed toroidal spiral, two pairs of metal disks mounted on coils of spiral at diametrically opposite points of circle of spiral turns. Sleeve embraces spiral at radial clearance whose amount ranges from 0.5 to 0.7 of preset magnitude of vertical static deformation of spiral at nominal load. Distance from end of sleeve to transverse plane of symmetry of torus spiral is selected from ratio h ≅ 0,5R where R is radius of spiral turn. Inner surface of each outer disk is profiled and its cross section is hyperbola. EFFECT: enhanced reliability. 2 dwg
