Three-directional friction adjustable strong-impact-resisting vibration isolator

Abstract

The invention provides a three-directional friction adjustable strong-impact-resisting vibration isolator comprising a base, an upper cover, a vibration isolation spring component, a damping buffering component and a shock insulation component, wherein the damping buffering component comprises a friction sheet and a friction ring and the inner surface of the friction ring contacts with the outer surface of the friction sheet. The shock insulation component comprises a rubber block, a metal ring and a gasket, wherein the friction ring is arranged on the metal ring in a sleeved mode. The rubber block is clamped between the metal ring and the gasket, wherein the gasket contacts with the base or the upper cover. The three-directional friction adjustable strong-impact-resisting vibration isolator is strong in shock insulation performance and particularly suitable for a vibration isolation system in military electronic equipment. Besides, the three-directional friction adjustable strong-impact-resisting vibration isolator further has the advantages of bringing convenience to the spacial three-directional friction damping regulation, being anti-abrasive, being corrosion resisting and the like.

Description

Technical field [0001] The invention relates to a vibration isolating and buffering device, in particular to a vibration isolator which can resist strong impact and has adjustable three-way friction damping force. Background technique [0002] Anti-shock isolators can effectively alleviate and avoid damage to electronic equipment or electromechanical equipment under high-impact environments. Its effect is obvious especially in military equipment, such as laser bombs or anti-ship missiles. The mechanical equipment and electronic instruments on the ship caused damage, and the ship lost its combat effectiveness. [0003] At present, the commonly used anti-shock vibration isolation components mainly include: metal spring vibration isolators, rubber shock absorbers, steel wire rope shock absorbers and oil pressure buffers, etc. Among them, rubber shock absorbers and steel wire rope shock absorbers can be well used in electronics. Equipment vibration isolation and small shock isolation,...
