Description
Technical field
This utility model belongs to engineering machinery field, and the phase place relating to ungraded amplitude device keeps, specifically
Relate to a kind of phase place keeper being applied to vibrated roller ungraded amplitude device.
Background technology
Spring in 1820, the oersted of Denmark found that electric magnet principle among once accidentally.
Electric magnet principle refers to the outside conductive winding matched with its power that is wound around at iron core, this is connected with
The coil of electric current has magnetic as Magnet.1822, French physician Arago and Gay-Lussac
Just finding, when electric current passes through the coiling wherein having iron block, it can make the iron block in coiling magnetize.This
It is actually being originally found of electric magnet principle.
The electric magnet of sturgeon (unit of reluctance) invention, makes it is seen that electric energy is converted into the bright outlook of magnetic energy,
This invention quickly spreads some coastal states of Britain, the U.S. and West Europe.1829, beautiful
State Electrician Henry has carried out some innovations to sturgeon (unit of reluctance) electromagnet apparatus, replaces with magnetoelectricity insulated conductor
Naked copper wire, therefore there is no concern that by copper conductor too close to and short-circuit.Owing to wire has had insulation
Layer, it is possible to they one are enclosed the land tightly around together, owing to coil is the most intensive, the magnetic of generation
Field is the strongest, thus substantially increases ability electric energy being converted into magnetic energy.By 1831, prosperous
Profit has manufactured experimently out one block of electric magnet updated, although its volume is the most little, but it can pick up 1 ton heavy
Iron block.
Now, we generally make bar shaped or ungulate shape it, so that iron core is more prone to magnetization.Separately
Outward, in order to make electric magnet power-off demagnetization immediately, we often use demagnetization soft iron faster or silicon steel
Material is manufactured.Such electric magnet is magnetic when energising, and after power-off, magnetic disappears the most therewith.Electromagnetism
Ferrum has in our daily life and is extremely widely applied, especially at crane, phone, automatically
Change the aspects such as control equipment, electromagnetic relay, magnetic suspension train and achieve the achievement of brilliance.Due to it
Invention also make the power of electromotor be greatly improved.
Electromagnetic brake is a kind of adapter that master end torsion conveys to passive side, can be according to needs
Combine freely, cut off or brake.Because using electromagnetic force to brake, referred to as electromagnetic clutch, braking
Device.Electromagnetic clutch, brake is the machine components making the movement parts in machinery stop or slowing down.System
Dynamic device is mainly made up of brake bracket, brake component and manipulation device etc..Some brake is also equipped with brake component
The automatic regulating apparatus in gap, electromagnetic brake has been widely used in various engineering machinery.But
In the vibrating machine of some stepless frequency modulation amplitude modulation, particularly in ungraded amplitude frequency modulation vibrated roller, nothing
The ungraded amplitude device of level amplitude modulationfrequency modulation vibrated roller is the relative phase by changing two parallel eccentric axes
Position, changes the exciting force being perpendicular to ground, regulates the device in relative rotation of two eccentric shafts.Typically
In the case of, the amplitude modulation mechanism of vibrated roller is all installed in compacting steel wheel, and steel wheel internal structure is complicated,
And installing space is little, for existing electric-liquid type brake and electromagnetic brake, structure is excessive, it is difficult to
Install.
