DISK-TYPE ELASTIC ELEMENT Russian patent published in 2018 - IPC F16F3/10 F16F1/32 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, instrument making and can be used for vibration isolation of process equipment, machine tools, instruments and other objects. Disk-type elastic element comprises disc-shaped elastic surfaces in the form of a truncated cone, with through grooves therein, connected by ribs directed along the lines forming a conical surface, with respect to the separating disk there are two elastic disk elements opposite and axisymmetric to it. Each of the disc-shaped elements comprises a disc-shaped resilient surface in the form of a truncated cone on which is made in a plane parallel to the bases of the truncated cone, three through grooves, with the formation of two truncated conical surfaces connected by three ribs directed along the lines forming the conical surface. In the central part of the separating disc, coaxially elastic elements are fixed damping cylinders made of injection polyurethane and entering with gaps in the holes at the tops of truncated conical surfaces. Damping cylinders are interconnected by an elastic insert consisting of an axis passing through coaxial holes in the separation disc and damping cylinders, and thrust disks connecting respectively the upper and lower damping cylinders with a separating disc. Resistant disks of the elastic insert fix the elastic disk elements with respect to the separating disc in three through grooves of the elastic disk elements. Perpendicularly to the separation disk, there are reinforced vibration protection elements fixed, respectively, in the three holes formed in the peripheral part of the partition disk, and made, for example, in the form of compression springs. Resistant disks of the elastic insert with an axis connecting the upper and lower damping cylinders with a separating disc are made of a rigid vibration damping material. Axis of the elastic insert is made of a combined, consisting of a rigid core with a polyurethane sheath surrounding it.

EFFECT: increase in the vibration isolation efficiency in resonance mode.
