SPRING VIBRATION ISOLATOR Russian patent published in 2016 - IPC F16F3/10 F16F15/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator includes a housing, a base, cylindrical equifrequent spring with damper made from elastomer inside, lower and upper spring stroke limiters made of elastomer and threaded sleeve. Housing is rigidly coupled with base composed by round centre plate rests on lower cylindrical spring stroke limiter. Said spring interacts with top and bottom limiters via bottom support barrel and spring top external cover rigidly jointed with threaded sleeve. Top spring stroke limiter made in form of a cylindrical sleeve is attached on cover. On end surface of cover is fixed elastic dynamic object stroke limiter made of elastomer. In cover there is a hole for viscous material injection in lubrication system, for example, solid oil. In axial cylinder-taper hole lower stroke limiter there are two additional damping elements, one of which has shape of cylinder-conic bushing and is made from polyurethane, and other is located inside first and is made in form of a cylindrical coil spring, inside which there is a resilient mesh element.

EFFECT: improved efficiency in resonant mode of vibration isolation.
