Ring damper // 2259504
FIELD: mechanical engineering.SUBSTANCE: ring damper comprises flexible cylindrical rings secured to the housing. The housing is made of panel whose face grooves receive cylindrical rings fitted with interference so that the projecting parts of the flexible cylindrical rings from both sides of the panel define flexible bearing arcs of the damper which are in a contact with the surfaces of the object to be damped and bearing surfaces of the vehicle or construction structure, or foundation.
