CASSETTE LOW-FREQUENCY VIBRATION ISOLATOR OF HIGH LOAD CAPACITY (CLVIHL) Russian patent published in 2013 - IPC F16F3/08 F16F1/362 

FIELD: machine building.

SUBSTANCE: vibration isolator includes housing with flange for its attachment to support, elastic bushings made from wire material of metal rubber, central bushing and attachment parts. Central bushing is made in the form of hollow cylinder-buffer consisting of cylindrical and conical parts. Inside cylinder-buffer there located is one or two compression springs that, in non-loaded state of vibration isolator, press the buffer with low force to upper shock-proof pad built in the cover. Cover is fixed on housing with screws and nuts. Damping cassettes are installed on each other in housing. Each cassette consists of housing, cover put on housing, elastic hysteresis element made in the form of bushing and composed of individual sectors-pushers of ring with central conical hole. Cover and bottom of cassette housing serve as guides at radial working offsets of pushers. The second shock-proof pad is fixed at vibration isolator housing bottom. Spacer plate that presses cassettes to each other is installed between upper cassette and upper pad.

EFFECT: improving vibration isolating properties and durability, and simplifying vibration isolator maintenance.
