FIELD: machine building.
SUBSTANCE: vibration absorber consists of a casing and a resilient element from elastomer interacting with a unit. The housing is made as a sleeve resting on the upper end of resilient element, and the collars connecting by means of peripheral recess the housing with the base. The profile of lateral surfaces of elastomer is formed hyperbolic as a bar of equal resistance with a constant stiffness in axial and transversal directions. The gauze damper base is composed by the plate with mounting holes. Lower plate is connected with the base. Upper pressure plate is connected with central ring clamped by coaxial ring connected with the base. Between the lower end of the piston and bottom of the bush the polyurethane elastomer is located.
EFFECT: more efficient damping in resonance mode, simplified design and assembly.
