Abstract
The utility model relates to a magnetic vibration isolator for a kinematic scheme, which comprises a barrel. A plurality of magnet yokes and permanent magnets are connected on a main shaft in the barrel, the permanent magnets are disposed orderly in between the two magnet yokes and the permanent magnets has the same polarity with the adjacent permanent magnets; fitted guide sleeves are positioned on the barrel and the main shaft. If the vibration happens, the main shaft moves relatively to the barrel. A magnetic flux passing through the barrel can be changed by a magnetic field produced by the permanent magnets connected with the main shaft. The action on an eddy flow by the magnetic field can block the displacement of the main shaft, so that the vibration reduction can be realized.
Description
Affiliated technical field
The utility model relates to a kind of magnetic vibration damper that is used for moving system.
Background technique
Existing dydraulic shock absorber is by cylinder body, at the built-in piston that matches of cylinder body, the damping hole that cylinder body two cavity oil liquid is communicated with is set on piston to be formed, when piston rod moves under the vibration force effect, can realize vibration damping by the pressure reduction that the damping hole on the piston is regulated cylinder body two cavity oil liquid automatically, still, because the accuracy of manufacturing height of this vibration damping equipment, therefore, cost height; Deficiencies such as the Sealing on cylinder body, the piston is fragile, exists the oil leaking pollution environment, reduces effectiveness in vibration suppression, and working life is short.
Summary of the invention
The purpose of this utility model provides that a kind of manufacturing simple in structure, easy, cost are low, the magnetic vibration damper of long service life, good damping result.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of magnetic vibration damper, it is characterized in that: be provided with cylindrical shell, be connected with several magnetic strategic points, permanent magnet on the main shaft that is provided with in cylindrical shell, permanent magnet places between the two magnetic strategic points successively, and permanent magnet is identical with the polarity of adjacent permanent magnet; The guide sleeve that matches is set on cylindrical shell, main shaft; The technical program is to adopt magnetic field theory in the physics, utilize vortex principle design, between this device main shaft and cylindrical shell, has a stable magnetic field, when producing vibration, relative movement is just arranged between main shaft and the cylindrical shell, and the magnetic field that the permanent magnet that is connected with main shaft produces changes the magnetic flux by cylindrical shell, produces eddy current on cylindrical shell, magnetic field hinders the displacement of main shaft to the effect of this eddy current, thereby has realized vibration damping.
The utility model is compared with existing dydraulic shock absorber, because the utility model is built-in with the axle of permanent magnet at cylindrical shell, damping force by magnetic medium realizes vibration damping, has advantages such as simple in structure, easy manufacturing, cost are low, long service life, good damping result.
