The lossless absorber comprises a magnetism isolating cylinder body (6), a soleplate (8), an upper magnet (3), a magnet piston (5), a lower magnet (7), a nonmagnetic piston rod (4) and a bracket splint (1). The soleplate (8) is arranged at the bottom of the magnetism isolating cylinder body (6); the upper magnet (3), the magnet piston (5) and the lower magnet (7) are arranged in the magnetism isolating cylinder body (6) from up to down, wherein, the upper magnet (3) uses the stiffness to adjust a bolt (2) for lifting the bolt on the top of the magnetism isolating cylinder body (6); the magnet piston (5) is connected with one end of the nonmagnetic cylinder rod (4); the other end of the nonmagnetic cylinder rod (4) passes through a throughhole at the center of the upper magnet (3) and the magnetism isolating cylinder body (6) for extending out of magnetism isolating cylinder body (6), and is connected with the bracket splint (1); the lower magnet (7) is arranged on the bottom of the magnetism isolating cylinder body (6); the lower magnetism of the magnet piston (5) is same with that of the lower magnet (7). The utility model has the advantages of long service life, no noise, compact and simple structure, high reliability, low manufacturing cost, good vibration effect and saving raw material consumption.
Description
Technical field
The utility model relates to a kind of vibration damper, is mainly used in the damping shock absorption of industrial machinery equipment vibrations, to reduce the damage of mechanized equipment vibrations to environment and adjacent facility.Belong to industrial machinery manufacturing industry and applied technical field.
Background technique
What at present, be used for that industrial vibration damper adopts is elastic element (as spring, rubber etc.) or the bellows vibration damper as damping member.Such vibration damper is the to-and-fro motion by elastic element or bellows, by Hooke's law F=Kx, in the to-and-fro motion of vibration, produces a power opposite with moving direction, and this mechanical resistance hinders shock motion, plays the effect of damping.This vibration frequency is very high, makes damper element be easy to generate fatigue ruption, and vibration damper can very fast forfeiture shock-absorbing function.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of non-contact type to can't harm vibration damper.
The purpose of this utility model is achieved in that a kind of harmless vibration damper, it is characterized in that described vibration damper is a cylinder shape facility, comprise every magnetic cylinder body, base plate, upper magnet, magnet piston, lower magnet, no magnetic piston rod and stent bearing plank,
Described base plate is fixedly set in every the magnetic cylinder base, described upper magnet, magnet piston and lower magnet all place from top to bottom in the magnetic cylinder body, wherein, upper magnet is regulated bolt with rigidity and is lifted on every magnetic cylinder body top, the magnet piston links to each other with no magnetic piston rod one end, the no magnetic piston rod the other end passes upper magnet and the through hole every magnetic cylinder body center stretches out outside the magnetic cylinder body, and be connected with stent bearing plank outside the magnetic cylinder body, lower magnet places on the base plate of magnetic cylinder base, described magnet piston bottom magnetic is identical with lower magnet magnetic, and magnet piston upper magnetic is identical with upper magnet magnetic.
Working principle: the magnet same sex is repelled each other, and very in the small distance scope, the generation that the vibrations variable in distance can be brought the huge same sex mutual expelling force of magnet realizes damping shock absorption near magnet surface.
The utility model has the advantages that: the utility model is a kind of contactless electromagnetic levitation type vibration damper, because magnetic suspension is contactless, does not have fatigue life, so the life-span is long, noise free, and compact structure is simple, reliability is high, low cost of manufacture, good damping effect, but conservation consumption.
Description of drawings
Fig. 1 is the general structure schematic representation of the harmless vibration damper of the utility model.
Among the figure: stent bearing plank 1, rigidity regulate bolt 2, upper magnet 3, no magnetic piston rod 4, magnet piston 5, in magnetic cylinder body 6, lower magnet 7, base plate 8.
Embodiment
Referring to Fig. 1, the harmless vibration damper that the utility model relates to is a cylinder shape facility, mainly by forming every magnetic cylinder body 6, base plate 8, upper magnet 3, magnet piston 5, lower magnet 7, no magnetic piston rod 4 and stent bearing plank 1.Described base plate 8 is fixedly set in every magnetic cylinder body 6 bottoms, described upper magnet 3, magnet piston 5 and lower magnet 7 all place from top to bottom in magnetic cylinder body 6, wherein, upper magnet 3 usefulness rigidity are regulated bolt 2 and are lifted on every magnetic cylinder body 6 tops, magnet piston 5 links to each other with no magnetic piston rod 4 one ends, no magnetic piston rod 4 the other ends pass upper magnet 3 and the through hole every magnetic cylinder body 6 centers stretches out outside magnetic cylinder body 6, and be connected with stent bearing plank 1 outside magnetic cylinder body 6, lower magnet 7 places on the base plate 8 of magnetic cylinder body 6 bottoms, described magnet piston 5 bottom magnetic are identical with lower magnet 7 magnetic, and magnet piston 5 upper magnetic are identical with upper magnet 3 magnetic.
Stent bearing plank 1 with need the facility of damping to link, rigidity is regulated bolt 2 can regulate the vibration damper rigidity.The vibrations of the vibrations facility that connects when stent bearing plank 1 repel each other and produce damping owing to the same sex when no magnetic piston rod 4 is passed to magnet piston 5, play shock-absorbing function.Because damping process magnet piston 5 and upper magnet 3, lower magnet 7 are contactless, so noise free.
