SPRING ANTIVIBRATION UNIT OF KOCHETOV WITH COMBINED DAMPER Russian patent published in 2017 - IPC F16F15/04 F16F7/08 F16F1/362 

FIELD: machine engineering.

SUBSTANCE: The damper consists of compression spring interacting with base of case and the pendulum suspension. The pendulum suspension is designed as a threaded rod, connected at one end to support arm, and the other - with the thrust washer and a nut. The nut is connected with the hub interacting with the upper end of the spring. The lower end of the spring rests on the ground. The base consists of an upper and lower plates connected by vertical plates. The upper plate is fixed bushing composite friction material. Spring is in two parts, between which the combined damper. The damper is designed as a mesh washer package, in the central part of the rod which is elastic-damping material. Net package includes interacting with the base of the elastic elements of the mesh frame, the cast elastomer - polyurethane. In its middle part of the stem is rigidly fixed to the central plate, on which the support rings are fixed. Upper and lower resilient mesh elements are connected respectively to the upper and lower lid of the mesh pack and the central plate. The central opening includes a coaxial rod to lock the rod vibro-isolated object.

EFFECT: efficiency of vibration isolation in resonance mode increase.
