Problems solved by technology

[0003] 1. Purpose of the invention: In order to solve the problem that the volume of the existing shock absorber changes with the change of the bearing capacity, the flexibility and the shock resistance cannot be unified and coordinated, the present invention provides a composite magnetic suspension damping shock absorber. The device combines the main spring, The combination of the damping structure and the magnetic levitation structure not only can carry a large load, but also is much smaller than the existing shock absorber, and its flexibility and impact resistance are better than the existing shock absorber

Abstract

The invention provides a composite magnetic floating damping vibration reducer, comprising a bottom plate and an upper cover above. The sides of the bottom plate and the upper cover are arranged with guide side plates between them to guide each other. The bottom plate and the upper cover are arranged with a main spring between to support the upper cover. The bottom plate is mounted with a cylinder which contains an upper and a lower permanent magnets with same polarity. The upper permanent magnet is arranged with a piston above, while the piston is connected to the upper cover via the piston rod. The upper permanent magnet and the piston are arranged with an auxiliary spring between. The invention has the advantage in the combination between main spring, damping structure, magnetic floating structure, and air spring, to improve the bearing function, improve the flexibility of main spring, and reduce the size of invention, with adjustable mounting height.

Description

1. Technical field [0001] The invention relates to a shock absorber, in particular to a composite magnetic suspension damping shock absorber applied to electromechanical equipment such as large centrifuges and motors. 2. Background technology [0002] With the rapid development of modern industry, various industries have higher and higher requirements for various electromechanical equipment, so the volume of powerful equipment is also increasing, such as centrifuges, large water pumps, large motors, etc. The larger the electromechanical equipment, the greater the vibration due to resonance or passing through the critical speed when it is working. The greater the vibration, it will not only produce annoying noise, but also affect the normal operation of the machine. Existing shock absorber mainly divides into two classes in order to reduce this vibration: one kind is the maglev shock absorber that main spring and maglev structure work in series. This type of shock absorber i...
