Description

Non-contact magnetic brake mechanism
Technical field
The present invention relates to a kind of braking brake mechanism in rotating mechanism, particularly a kind of non-contact magnetic brake mechanism.
Background technology
Traditional rotating mechanism brake mainly contains two kinds of forms: the first adopts hydraulic braking and air-pressure brake, in use often leakage phenomenon can occur, makes the brake efficiency of brake bad; It two is electromagnetic brakes, it is the drum brake that is produced braking force by electromagnetic attraction, electromagnet and brake drum end contact during braking, adopt the mode of electric current to control the braking force size, the common ground of above-mentioned two kinds of forms are revolving parts with stationary parts between with mechanical force or electromagnetic force it is contacted after, frictional force by its contact-making surface reduces rotating speed until stop, its drawback is that dynamic response is slow, the parts frictional heating is fragile, increase maintenance frequency, when braking, also can produce noise, complicated integral structure.
Summary of the invention
The purpose of this invention is to provide a kind of compact conformation, rapidly and efficiently, noncontact, without wearing and tearing, do not produce the non-contact magnetic brake mechanism of noise, overcome the deficiencies in the prior art.
Non-contact magnetic brake mechanism of the present invention includes stator, in the medial support of stator rotor is arranged; Described rotor comprises rotating shaft, and inner chamber one end that is positioned at stator in rotating shaft is provided with permanent magnet, and the other end is provided with rotor coil; Described stator inboard is provided with the first stator coil and the second stator coil, and the first stator coil is positioned at the outside of described permanent magnet, and the second stator coil is positioned at the outside of rotor coil; External end head at rotor is equipped with drive; Described the first stator coil is connected by wire with switch, resistance, rotor coil; Be connected for wire between described the first stator coil and the second stator coil.
Non-contact magnetic brake mechanism of the present invention, wherein said stator comprises shell, is fixedly connected with left end cap at the left end of shell, the right-hand member of shell is fixedly connected with right end cap, described rotating shaft by bearings on left end cap and right end cap.
Non-contact magnetic brake mechanism of the present invention, rotor portion is by the permanent magnet that is located at the permanent magnetic material in the rotating shaft and excitation rotor coil arranged in co-axial alignment, and two groups of excitation stator coils with fixing are radially corresponding respectively, consist of magnetic-electricity conversion and electricity-magnetic conversion two parts, the magnetic field rotating direction that electricity-the magnetic conversion forms is opposite with the rotating shaft direction of rotation of magnetic-electricity conversion.This mechanism is driven by rotating mechanism by drive at the running shaft and rotates, and permanent magnet and rotor coil rotate with rotating shaft, produce induced potential in the first stator coil, and switch is in off-state; When the needs braking brake, turn on-switch is connected the induced potential in the first stator coil respectively in stator coil and the rotor coil, by the direction of winding, make the magnetic field that forms counter-rotating in stator coil and the rotor coil, reach the effect of rotor braking brake.Have advantages of compact conformation, rapidly and efficiently, noncontact, without wearing and tearing, do not produce noise.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is the wiring schematic diagram of each coil and permanent magnet among the present invention.
Embodiment
As shown in Figure 1, 2: 4 is shell, the left end of shell 4 is fixedly connected with left end cap 3 by screw, the right-hand member of shell is fixedly connected with right end cap 9 by screw, an end is fixed with the first stator coil 5 on the madial wall of shell 4, the other end is fixed with the second stator coil 7, and above-mentioned parts have formed stationary part.
There is rotating shaft 1 center at left end cap 3 and right end cap 9 by bearings, the inner chamber that is positioned at shell 4 in rotating shaft 1 is fixed with permanent magnet 6 and rotor coil 8, permanent magnet 6 is located at the inboard and coaxial setting of the first stator coil 5, and rotor coil 8 is located at the 7 inboard and coaxial settings of the second stator coil.
Rotating shaft 1 external end head at rotor is equipped with drive 2, and drive 2 is gear.
The first stator coil 5 and switch 10, resistance 11, rotor coil 8 are connected by wire.Be connected for wire between the first stator coil 5 and the second stator coil 7.
During installation, size according to required braking moment, the gear graduation ratio of selection from rotating shaft 1 to rotating mechanism, when rotating shaft 1 is rotated with rotating mechanism, the rotor driven rotation produces induced potential in the first stator coil 5, this moment, switch 10 was in off-state, because coil is not closed, so electromotive force is only arranged, no current is to rotor brakeless braking action, when the needs braking brake, turn on-switch 10 forms the loop, generation current, induced current in the first stator coil 5 is connected respectively the second stator coil 7 and rotor coil 8, by the direction of winding, make the magnetic field that forms counter-rotating in the second stator coil 7 and the rotor coil 8, reach the effect of rotor braking brake, this moment will be because the excitation winding that the second stator coil 7 and rotor coil 8 consist of will produce induced current, with the electric current that strengthens in the closed-loop path, for avoiding burning winding, externally the loop installs resistance 11 additional to reduce the electric current of home loop, in concrete the application, also can electric energy input storage battery will be produced again.
