Abstract

The utility model discloses an inherent steel wire vibration absorber in the mechanical field, wherein a through-hole is positioned in the middle of the upper clamping plate and the lower claming plate, and a limit screw rod through the through-hole is connected with at least a limit mechanism capable of limiting the maximum displacement of the circular steel wire. The limit mechanism is equipped between the upper clamp plate and the lower clamp plate, or/and on the surface of the equipment frame connected with the upper clamp plate, and/or on the surface of the base connected with the lower clamp plate. The elastic element is the butterfly spring or the spiral spring. The limit element is the limit sleeve, limit nut, the upper and lower clamp plate of the vibration absorber, and the equipment frame and base. One end of the limit screw rod is connected with the vibration isolator frame through the upper clamp plate, and the other end is connected with the base through the lower clamp plate. The utility model is reasonable in design, simple in structure, easy in operation, with the steel wire vibration absorber integrated with the limiter for simplification of the vibration absorbing system, satisfying the requirement under various conditions and widening the usage of the steel wire vibration absorber.

Description

Carry the wire rope damper of snubber

Technical field

The utility model belongs to field of mechanical technique, especially a kind of wire rope damper that carries snubber that is used for various dynamic power machines and work mechanism vibration damping, noise reduction, shock isolation.

Background technique

The kind of wire rope damper in the prior art, form are a lot, but are not with snubber, when system is necessarily required having by the maximum displacement of vibration isolation object, often have to install additional in addition independent snubber, and the snubber that installs additional makes the vibration insulating system complexity.In the narrow occasion in some space, Chang Wufa installs independent snubber additional, thereby makes the application of vibration damper be subjected to certain restriction.

The model utility content

Above-mentioned deficiency at prior art, the technical problems to be solved in the utility model provides a kind of wire rope damper that carries snubber, and it is installed in snubber in the vibration damper, and both are united two into one, both simplify the layout of vibration insulating system, and can be applied to the narrow occasion in space again.

The technical solution of the utility model is: the wire rope damper that originally carries snubber is the same with vibration damper of the prior art, and wire rope twines and is fixed between punch holder, the die holder with helical.Specialization is: the middle part at punch holder and die holder has through hole, is through and is socketed with the limit structure of being made up of elastic element and limit element that at least one can limit the annular wire rope maximum displacement on the spacing screw rod in the through hole.The equipment rack surface that described limit structure is arranged between the upper and lower clamping plate and links together with punch holder, or the surface of the pedestal that links together with die holder.Elastic element in the described limit structure is butterfly spring or helical spring.The limit element that cooperates with elastic element in the described limit structure is die holder, equipment rack or a pedestal on spacing collar, limit screw cap, the vibration damper.Described spacing screw rod one end passes punch holder and is linked to each other by the device for vibration insutation frame, and the other end passes die holder and links to each other with pedestal.

The utility model is reasonable in design, and is simple in structure, implements easily wire rope damper and snubber to be integrated, and simplified the structure of vibration insulating system, adapted to the needs of various different conditions, widened the purposes of wire rope damper.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.Shown in accompanying

drawing

1,2,3,4, described wire rope damper is simple in structure, and it is made up of punch holder 3 and die holder 2 fixing spirally-wound wire rope 5.With regard to vibration damper itself, it does not comprise equipment rack 4 and the pedestal 1 in the diagram.When being to use, the characteristics of vibration damper must be fixed on pedestal 1 and by between the device for vibration insutation frame 4, so the utility model also utilizes these characteristics to finish limit function, in all being presented in the diagram with pedestal 1 with by device for vibration insutation frame 4.Among Fig. 1 on spacing screw rod 6 socket two spacing elastic element butterfly springs 8, one of them is arranged on by between device for vibration insutation frame 4 and the nut 7, another is between punch holder 3 and die holder 2, they and sleeve or nut 12 are formed position-limit mechanism together.When by of the displacement of vibration isolation (or every dash) equipment in the equipment proper functioning that exerts an influence under the external force excitation, just contact with the punch holder 3 that is tightened together by vibration isolation (or every dashing) equipment with spacing screw rod 6, thereby limited the displacement of punch holder, reached spacing purpose (together remaining, as not give unnecessary details).Be provided with three 8, one of spacing elastic element butterfly springs in the accompanying drawing 2 and be arranged between equipment rack 4 and the nut 7, in addition two are arranged between die holder 2 and sleeve or nut 12, the punch holder 3, and they form position-limit mechanism together.Be provided with 8, one of two butterfly springs among Fig. 3 and be arranged between equipment rack 4 and the nut 7, another is arranged on the die holder 2.Fig. 4 has shown two butterfly springs 8 and a helical spring 14, a spiral spring 8 is arranged between equipment rack 4 and the nut 7, another is arranged between pedestal 1 and the nut 7, and helical spring 14 is arranged between the upper and

lower clamping plate

3,2, and they form limit structure together.Among Fig. 1-3, spacing screw rod 6 upper ends are fixing with nut 7, and adopting two nuts 7 is in order to lock; Spacing screw rod 6 lower ends and pedestal are connected to a fixed with screw thread.And spacing screw rod 6 upper and lower ends all adopt nut 7 fixing among Fig. 4.Diagram is explanation for example just, is not to be whole protection content of the present utility model.Limit structure of the present utility model can carry out spacing in three mutually perpendicular directions of XYZ axle, and is on-the-spot adjustable in the spacing amount of Vertical direction.
