Problems solved by technology

Therefore, it is difficult for conventional shock absorbers using a single-turn steel wire rope to meet the requirements of greater damping and stiffness at the same time.
In addition, this kind of shock absorber is generally characterized by soft spring stiffness, and it is difficult to ensure a relatively stable state under unexpected large loads.

Embodiment Construction

[0021] The following will be specifically described in conjunction with the accompanying drawings of the embodiments.

[0022] Such as figure 1 with figure 2 :

[0023] In the figure: 1-steel wire rope of the outer ring, 2-steel wire rope of the inner ring, 3-upper splint of the inner ring, 4-upper splint of the outer ring, 5-lower splint, 6-Butterfly spring group, 7-pre-top clearance.

[0024] The inner ring wire rope 1 and the outer ring wire rope 2 are composed of two parts, the left side and the right side. The inner ring wire rope 1 and the outer ring wire rope 2 rotate in opposite directions, and each forms a left-right symmetrical structure; the inner ring wire rope 1 on the left or right side The winding direction of the wire rope located at the same position as the outer ring wire rope 2 is opposite. In the unloaded free state of the shock absorber, there is a pre-top gap 7 between the upper clamping plate 3 of the inner ring and the upper clamping plate 4 of the ...

Abstract

The invention discloses a double-circle steel wire rope shock absorber, consisting of an outer-circle steel wire rope, an inner-circle steel wire rope, inner-circle upper clamping plates, outer-circle upper clamping plates, a lower clamping plate and a plurality of belleville spring assemblies. The double-circle steel wire rope shock absorber provided by the invention can guarantee the normal exertion of shock absorption performance in the case of large predeformation and guarantee no conquassation under quite great loads; therefore, the safety coefficient and the capability of coping with an accident are improved; the broadband high-attenuation of shock by the shock absorber under the working conditions of precompression and small amplitude (several millimeters) can be realized; in addition, the double-circle steel wire rope shock absorber has the characteristics of long service life, good shock absorption effect and the like.

Description

technical field [0001] The invention relates to a double-circle steel wire rope shock absorber, which can be widely used in vibration isolation, noise reduction and shock absorption of equipment such as ship propulsion systems, diesel generator sets and large engine rotor systems. Background technique [0002] The main vibration isolation element of the wire rope shock absorber is the steel wire rope. When the bending deformation of the steel wire rope is small, the internal strands and strands, wires and wires will not slide relative to each other due to the action of static friction, and have large rigidity and small damping. When the bending deformation of the steel wire rope increases to a certain extent, the internal strands and strands, wires and wires will overcome the friction force and produce relative slip, and overcome the sliding friction force to do work, consume energy, and have greater damping. and less rigidity. Therefore, it is difficult for the convention...
