DISH VIBRATION ABSORBER FOR PROCESSING EQUIPMENT Russian patent published in 2014 - IPC F16F3/10 F16F15/08 

FIELD: machine building.

SUBSTANCE: vibration absorber consists of a casing and a resilient element interacting with a unit. Two guide bushes joined by a common ring bottom turned to a base are secured at the casing base by a layer of cast polyurethane. A pack of dish-like resilient elements is installed axisymmetric and coaxial to the guide bushes, the elements rest by the bottom backing surfaces against the ring bottom made of an antifriction material and by the top backing surfaces against the cover embracing the cast polyurethane layer with a gap. By means of a fastening element the cover is connected to a load bearing threaded element, for example, a bolt with its head being covered by the cast polyurethane layer. The bushes on the open part side are fitted with ring flanged edges, coaxial to the axes of the bushes on which resilient rings are fixed with a gap in respect to the inner cover surface and serve as resilient limiters of moving elements of the vibration absorber. Resilient damping mesh elements are set inside and outside the dish-like resilient elements; they are made as pieces of an off-grade rope of different diameter mixed up with the scraps of polyurethane products.

EFFECT: increased efficiency of space vibration absorption and simplified design and installation.
