RESILIENT DISH-SHAPED ELEMENT Russian patent published in 2017 - IPC F16F3/02 F16F1/32 

FIELD: machine engineering.

SUBSTANCE: dish-shaped element comprises two resilient elements set oppositely in respect to the vertical axis of a separating element. Each resilient element comprises dished resilient surface in the form of a truncated cone, three through grooves forming two truncated conical surfaces connected by three fins are provided on the above surface in the plane parallel to the bases of the truncated cone. Damping cylinders made from cast polyurethane are fixed in the central part of the separating element coaxially to the resilient elements and enter the holes at the truncated conical surfaces' vertices with a gap. Damping elements of bush type with clearance enter the dampening cylinders, they are secured by means of the resilient rings. The resilient rings are secured in holes at tops of the truncated cone surfaces of the resilient element. The separating element is made of three layers: the central layer is made of a rigid vibration damping material, for example of the "Agat" type, and the symmetrically arranged upper and lower layers are made of a mesh frame filled with sponge rubber.

EFFECT: increased efficiency of vibration isolation in resonance mode.
