Description
Technical field
The utility model relates to a kind of vibration damper, particularly a kind of magnetic vibration damper.
Background technique
Traditional vibration damper has spring and fluid damping formula.Spring utilizes its elastic recovery properties to realize vibration damping, and still, spring damping is easy to generate exciting and fatigue, and the high frequency damping property is poor, also produces noise during work; The fluid damping formula is made up of the cylinder barrel of piston that has flowing hole and cooperation with it, piston by a rod member with connected by damping body, fluid (oil, gas or other flowing medium) is housed in cylinder barrel, during piston motion, fluid produces damping force to piston and realizes vibration damping by flowing hole, but this vibration damper, damping force changes limited, and also difficulty is applicable to dither, and fluid easily leaks.In recent years, multiple magneto vibration damper has appearred, improved traditional vibration damper performance to some extent, but following defective is arranged: 1. utilize two repulsion between the permanent magnet same polarity to realize vibration damping, this vibration damper requires permanent magnet that high coercivity is arranged in order to avoid demagnetization, but the rare earth permanent magnet Curie temperature of high-coercive force is low at present, can't adapt to hot environment; 2. the magnetic line of force in the magnetic repulsion type vibration damper is laterally extruded from axial running clearance because of repelling each other, and can't form the closed-loop path, and leakage field is very big, befouling environment.
Summary of the invention
The utility model designs a kind of magnetic vibration damper, can overcome the defective of above-mentioned traditional vibration damper and existing magneto vibration damper, vibrational energy can be converted to useful electric energy, and cost is low, non-maintaining, the life-span is long.
The utility model is realized by following technological scheme.
The utility model is made up of stator and mover, gappedly between stator and the mover does not contact.The annular permanent magnet of axial charging all is set in stator and mover, and two annular permanent magnets radially opposite pole is parallel relatively; Perhaps any one party is provided with the annular permanent magnet of axial charging in stator and mover, and the opposing party is provided with and the radially parallel relative magnetic guiding loop of annular permanent magnet.At the two ends of annular permanent magnet the magnetic conduction annulus is set, the magnetic conduction annulus of stator and mover radially protrudes permanent-magnetic clamp separately, the magnetic conduction annulus septal space of stator and mover is parallel relatively, and the magnetic conduction annulus of stator and mover is because the magnetic line of force of permanent-magnetic clamp imports attracts each other.Between the magnetic conduction annulus of stator and mover inductor coil is set, inductor coil and stator magnetic conduction annulus are fixed.During the utility model work, relative displacement takes place in stator and mover vertically, because magnetoresistive effect, the cylindrical of the interior circle of the magnetic conduction annulus of stator and the magnetic conduction annulus of mover produces oblique pulling mutually, oblique pulling is decomposed into radial and axial power, radial force offsets and is zero, and axial force is the damping force that vibration damping needs; Stator and mover take place vertically relative displacement the time, produce induction current at inductor coil, this electric current charges a battery or directly use through rectifying and pressure-regulating, simultaneously, the magnetic field of being known this electric current by Lenz's law hinders stator and mover relative displacement, and obstruction power also is the damping force that vibration damping needs.Described stator and mover can be changed mutually according to practical application, and promptly stator is as mover, and mover is as stator.During use mover with connected by damping body, stator connects with fixed base.
The utlity model has existing all advantages of magneto vibration damper, and also have following advantage:
1. the utility model utilizes stator and mover permanent magnetic gravitation to realize vibration damping, and it is not very high that the coercivity of permanent magnet is required, and has enlarged the scope of choosing permanent magnet; And because stator and mover attract magnetic flux to pass formation closed-loop path, gap, so leakage field is very little, environmental pollution is little.
2. utilize inductor coil that vibrational energy is converted to available electric energy, rather than resemble spring piston formula vibration damper or some magneto vibration damper and with friction mode vibrational energy is converted to thermal waste and falls.
3. the utility model utilizes permanent magnetism power and magnetic force induced electricity to form damping power simultaneously, and effectiveness in vibration suppression is better.
4. not necessarily very high to the coercivity requirement of permanent magnet, under guaranteeing that remanent magnetism requires, can select the permanent magnet of high-curie temperature; Any one party is provided with the annular permanent magnet of axial charging in stator and mover, and the opposing party is provided with and the parallel vertically relative magnetic guiding loop of annular permanent magnet, and a side that will be in high temperature in actual applications is provided with magnetic guiding loop, and the opposing party is provided with annular permanent magnet.Owing to these two reasons, the utility model can the higher environment of adaptive temperature.
