Description
Technical field
The utility model belongs to the motor brake field, a kind of motor dead electricity brake structure particularly.
Background technology
Motor is commonly called as motor, it is a kind of device of realizing electric energy is changed torque according to the law of electromagnetic induction, its work critical piece comprises fixed part stator and rotating parts rotor, electric energy rotates rotor by electromagnetic induction principle generation torque in stator when work, and rotor drives the purpose that other workpiece rotates to reach power stage again.Motor has startup soon as a kind of power easy to use, and the reaction time is short, and the multiple advantage such as powerful is used very extensive in daily life and industrial production.Motor can reach rated speed fast after the energising, and certainly suddenly after the outage, motor is under effect of inertia, and motor reel still can continue to rotate a period of time and just can stop fully.This situation in most of the cases can't have a negative impact, but needs to tend to cause conduction eror on the implement of accurate transmission at some, production operation is affected adversely, even also personnel's injury accident may occur.Therefore all be equipped with brake gear on these motor, but all there is complex structure in existing most of brake gear, retro-speed is excessively slow, reacts insensitive, the shortcoming that the dead electricity braking effect is relatively poor.
The utility model content
The purpose of this utility model provides a kind of motor dead electricity brake structure, and it has, and brake structure is simple, and retro-speed is fast, the advantage of good braking effect.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of motor dead electricity brake structure, the casing and the end cap that comprise motor, rotor between casing and end cap is positioned at the stator that casing inner wall cooperates with rotor, and lays respectively at the brake block group on armature spindle and the end cap, it is characterized in that, described rotor has male cone (strobilus masculinus), and described stator has inner conical surface, and described male cone (strobilus masculinus) and described inner conical surface tapering are complementary; Also be provided with spring on the described armature spindle, described spring is between rotor and end cap.
Preferably, described spring is positioned at the tip of the male cone (strobilus masculinus) of described rotor.
Preferably, be connected by radial-thrust bearing between described armature spindle and the described end cap.
Preferably, described spring is between rotor and bearing.
Preferably, also be provided with support ring on the described armature spindle.
Preferably, also be fixed with the fan blade that is positioned at the end cap outside on the described armature spindle, the relevant position is separately installed with the brake block group on described fan blade and the end cap.
Compared with prior art, motor dead electricity brake structure of the present utility model by becoming male cone (strobilus masculinus) to match with inner conical surface rotor and stator design, can produce electromagnetic force between rotor after the energising and stator, makes to produce between rotor and the stator to relatively move; Also be provided with spring on the described armature spindle, described spring is between rotor and end cap, and opposite rotor and the stator of stoping with electromagnetic force of the elastic force of spring relatively moves; Certainly after electromagnetic force enough overcomes greatly the elastic force of spring, the rotor relative stator moves, the brake block component that lays respectively on armature spindle and the electric motor end cap is left, therefore motor can normally rotate, and certainly after the suddenly outage of motor, just no longer production electromagnetic force between rotor and the stator, this moment, rotor resetted under the spring force effect, make that the brake block group is bonding brakes, so rotor can stop operating fast under braking force just.This brake apparatus is not only simple in structure, and retro-speed is fast, good braking effect.

Embodiment
Below in conjunction with accompanying drawing and embodiment the technical solution of the utility model is described.
As shown in Figure 1, the utility model is a kind of motor dead electricity brake structure, the casing 10 and end cap 11 that comprise motor, rotor 20 between casing 10 and end cap 11, be positioned at the stator 30 that casing 10 inwalls cooperate with rotor 20, and lay respectively at the brake block group 40 on rotor 20 axles and the end cap 11, described rotor 20 has male cone (strobilus masculinus) 21, described stator 30 has inner conical surface 31, and described male cone (strobilus masculinus) 21 is complementary with described inner conical surface 31 taperings; Also be provided with spring 50 on described rotor 20 axles, described spring 50 is between rotor 20 and end cap 11.Compared with prior art, motor dead electricity brake structure of the present utility model, match with inner conical surface 31 by rotor 20 and stator 30 are designed to male cone (strobilus masculinus) 21, between rotor after the energising 20 and stator 30, can produce electromagnetic force, make to produce between rotor 20 and the stator 30 to relatively move; Also be provided with spring 50 on described rotor 20 axles, described spring 50 is between rotor 20 and end cap 11, and opposite rotor 20 and the stator 30 of stoping with electromagnetic force of the elastic force of spring 50 relatively moves; Certainly after electromagnetic force enough overcomes greatly the elastic force of spring 50, rotor 20 relative stator 30 move, the brake block group 40 that lays respectively on rotor 20 axles and the electric motor end cap 11 is separated, therefore motor can normally rotate, and certainly after the suddenly outage of motor, just no longer production electromagnetic force between rotor 20 and the stator 30, rotor 20 resets under spring 50 elastic force effects at this moment, make brake block group 40 bonding brakings, so rotor 20 can stop operating fast under braking force just.This brake apparatus is not only simple in structure, and retro-speed is fast, good braking effect.
For the same electromagnetic force opposite direction that reaches between rotor 20 and the stator 30 of the bullet that guarantees spring 50, described spring 50 is positioned at the tip of the male cone (strobilus masculinus) 21 of described rotor 20; Simultaneously when rotor 20 relative stator 30 are moved radially, rotor 20 keeps radially that the axle center does not deflect, and guarantees the stable of motor rotor 20 rotations, is connected by radial-thrust bearing 60 between described rotor 20 axles and the described end cap 11; In order to promote the sensitivity of spring 50, described spring 50 can be in motor power failure state moment between rotor 20 and bearing 60, and spring 50 can reset rotor 20 in time and brake; In addition, also be provided with support ring 70 on described rotor 20 axles, can further guarantee the stationarity of rotor 20 rotations.In addition, in order to make things convenient for the installation of brake block group 40, also be fixed with the fan blade 12 that is positioned at end cap 11 outsides on described rotor 20 axles, the relevant position is separately installed with brake block group 40 on described fan blade 12 and the end cap 11.
Motor dead electricity brake structure of the present utility model, not only simple in structure, and also retro-speed is fast, good braking effect.
