FIELD: vibration protection means for building industry, particularly vibroinulated foundations for machines, engines, or ordnance. ^ SUBSTANCE: vibroinsulated foundation comprises bath and foundation block arranged in the bath so that the foundation block is spaced from bath walls and bottom. The foundation block is higedly connected with bumpers, which in turn are attached to foundation block by means of hinged lever. The lever connects foundation block with support member of bumper. The bumper has pendulum suspension means made as threaded rod with spherical profile on one rod end and threaded bush also having spherical profile. Both spherical profiles cooperate with conical surfaces of upper and lower plates correspondingly. Resilient member is made as serially connected resilient disc means formed as disc springs connected with each other along outer diameters by means of ring having T-shaped profile and along inner diameters by means of ring having inner surface cooperating with outer bush surface. One bush end is fixedly secured to the base, another bush end is slidably installed in guiding bush. ^ EFFECT: increased efficiency of three-dimensional vibration protection and simplified foundation structure. ^ 2 dwg |
