Embodiment
The utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
Refer to Fig. 1, Fig. 2, a kind of micro ultrathin Quick-speed braking arrangement, including stator 1, rotor 2, coil 3, housing 4, brake
Car piece 5, spring 6, screw 7, rotor 2 coordinate the center for being installed on stator 1 using gap；The bottom of stator 1 is provided with
Annular groove 8, several stepped holes 9 connected with annular groove 8；The coil 3, which is fitted into housing 4, forms overall magnetic coil, should
Overall magnetic coil surround and is fixed in one entirety of formation on the axle of rotor 2；The brake block 5 is provided with tapped through hole, stops
Car piece 5 is positioned in annular groove 8 and positioned at the underface of overall magnetic coil；Spring 6 is set on screw 7, the external diameter of spring 6
More than the hole diameter of stepped hole 9；The end of screw 7 upward through spring 6, stepped hole 9 aperture after with foregoing brake block 5
Tapped through hole is threadedly coupled, and now the one end of spring 6 pushes against the nut of screw 7, the other end pushes against the step surface of stepped hole 9 and is in
Between free state and compressive state.
Further, the axle of the overall magnetic coil and rotor 2 being made up of coil 3, housing 4 is connected using tight fit
Connect.
Further, coordinated at the cooperation of the brake block 5, screw 7 and stator 1 using gap, and brake block 5 can be
Slided up and down in annular groove 8, screw 7 can slide up and down in stepped hole 9.
Referring to Fig. 1, a kind of operation principle of micro ultrathin Quick-speed braking arrangement of the utility model is as follows：
Electric current is produced after the energization of coil 3, and then produces magnetic field, housing 4 is magnetized, and produces magnetic force, and then by brake block 5
(now spring 6 is in compressive state) is sucted, brake block 5 is linked together with housing 4 as an entirety, i.e. rotor 2
Being linked together with stator 1, the rotating speed for making rotor 2 by the frictional force between brake block 5 and housing 4 reduces, until 0 is reduced to,
So as to complete braking procedure, while can be entered by adjusting the size of the electric current in coil 3 come the magnetic force size of adjustment housings 4
And the frictional force between brake block 5 and housing 4 is adjusted to control the rotating speed of rotor 2.
Current vanishes after coil 3 powers off, the magnetic force of housing 4 also disappear.By the pulling force of spring 6 by brake block 5 and shell
Body 4 separates, i.e., rotor 2 separates with stator 1, and rotor 2 recovers to run well.
The utility model is simple in construction, easy to process, and brake force is adjustable, and rotating speed is adjustable, and size can be very small, thickness
Up to 6mm, so that the braking of micromachine is possibly realized.
Technical principle of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the limitation to scope of protection of the utility model can not be construed in any way.Those skilled in the art
Various modifications or supplement are made on the basis of the utility model or is substituted using similar mode, without departing from this reality
With new structure or surmount scope defined in the claims, protection category of the present utility model all should be belonged to.
