Description
Technical field
The technology of the present invention relates generally to a kind of magnetic brake, especially a kind of for the automatically controlled of large inertia equipment braking
Wound-rotor type magnetic brake, belongs to technical field of magnetic transmission.
Background technique
Because magnetic drives be it is non-contacting, one of biggest advantage be exactly can with overload protection, in addition because
Magnetic drives do not need lubricating oil, therefore magnetic means is more cleaned without pollution and leakage.
Eddy-current brake is a kind of device that retarding braking is carried out using electromagnetic principle.Mainly by with axis with identical revolving speed
The braking copper dish of rotation and be fixed on cabinet by conductor loop around iron core form.When conducting wire is powered according to the right-hand rule, iron
Core just has magnetism, and the copper dish of movement can cutting magnetic induction line.According to left hand rule, electric current is in magnetic field by the effect of power, resistance
The only movement of conductor.In addition, the electric current in conductor generates thermal power.Will not both be generated without foundation according to energy to disappear without foundation
Principle, electric current generate heat be by axis rotation energy it is converted come, sending heat more multi-axis turning energy it is fewer, in
It is that axle speed will slowly lower until being zero.
Magnetic coupling transmission device be by magnetic coupling and mechanical gear Integrated design in a compact cabinet,
As a kind of flexible apparatus, it is connected to motor and load, stepless speed regulation can be carried out to input speed and Ding Bi slows down.For
Many has the work mechanism of large inertia, and rotary inertia is big, and downtime is too long, it is often necessary to quick shutdown is braked, using existing
Some friction type brakes not only waste mass energy, but also are easily damaged mechanical equipment, cause personal safety accident, because
This design it is a set of can energy saving and safe and efficient magnetic braking apparatus become market in urgent need.
Summary of the invention
It is proposed of the invention, it is therefore an objective to develop a kind of vehicle magnetic brake by relay control, make control for brake
Quickly, convenient, sensitive.
The technical solution of the invention is as follows is achieved:
A kind of automatically controlled Wound-rotor type large inertia equipment magnetic brake, including cabinet, stepless speed regulation type magnetic coupling, revolving speed
Adjuster, magnetic coupling output shaft, deceleration gear are to pinion gear, gear wheel, bearing I, brake axle, bearing II, Wound-rotor type system
Dynamic device, copper dish seat, cooling fin, copper dish, upper fixed disk, roll, copper wire, lower fixed disk, electric-controlled box, the stepless speed regulation type
Magnetic coupling is mounted on cabinet) in, the revolving speed of magnetic coupling output shaft can be with stepless speed regulation by adjusting speed regulator；
The pinion gear of deceleration gear pair is mounted on magnetic coupling output shaft, and gear wheel is mounted on brake axle, and pinion gear, gear wheel are nibbled
Reduction of speed is compared in conjunction surely；It is characterized in that the brake axle is supported on cabinet by bearing I and bearing II, brake axle inner face spiral shell
Nail is fixed with copper dish seat, and copper dish seat is equipped with cooling fin and copper dish, and copper wire is wound on roll composition iron-core coil；6 groups of iron core lines
Circle is positioned by seam allowance, is confined on upper fixed disk and lower lower fixed disk by screw respectively and is formed coil group, the lower fixation of coil group
Disk is confined on cabinet with screw, and electric-controlled box is fixed outside the enclosure, built-in coil group supplying cell and power control relay,
Closing coil group power supply, coil group generate magnetic field, and the copper dish cutting magnetic line of rotation, which generates magnetic induction force, brakes brake axle.
Compared with prior art, it is an advantage of the invention that it will be apparent that being mainly manifested in:
1, not braking or on-position is controlled by the disconnected or logical of power source for relay control, keeps control for brake quick, convenient, clever
It is quick.
2, it is powered with wound core coil and generates magnetic field, it is at low cost convenient for manufacture.
