Abstract
The utility model discloses a kind of brake motor, not locking while mainly having solved the brake holding that the brake motor of prior art may have, even if power-off rotor can not be braked, or brake unstable, when load is large, drag the drawback that rotor rotates, its technical scheme is mainly that inflatable thing is set in brake motor, when brake motor power-off brake but rotor while still rotating, to the heating of switching on of inflatable thing, dilatant expanded by heating promotes the braking of armature to brake motor rotor, arrange like this, simple in structure, in the time of can effectively avoiding this braking of brake motor load can also dragging motor rotation etc. phenomenon, convenient and reliable, safety and stability.
Description
Technical field
The utility model belongs to mechanical fitting technical field, relates to a kind of motor, is mainly a kind of brake motor.
Background technology
Brake motor is for controlling motor inertia, make it meet the requirements of accurate location, realize mechanical auto-action, be suitable for rising in all kinds of mechanical rotation systems clutch, adjusting microinching, speed change and commutation etc., its groundwork principle is that motor afterbody has electromagnetism brake holding, its adhesive of also switching on of motor when energising, and at this moment it is not braked motor, its also power-off when motor power-off, brake holding is checked motor under the effect of spring.
The motor of prior art design, has simple in structurely, easy for installation, and volume is little, the advantage such as lightweight, but have some identical shortcomings, i.e. the brake holding of brake motor can not locking, even power-off, rotor can not be braked, or brakes unstablely, when load is large, also can drag rotor rotation etc.
Utility model content
The deficiency existing for prior art, it is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, the higher brake motor of fail safe that can effectively avoid not locking of brake holding that brake motor power-off is braked.
For achieving the above object, the utility model provides following technical scheme: a kind of brake motor, comprise housing, bonnet, rotor and armature, on described armature, be provided with temperature-sensitive dilatant, described temperature-sensitive dilatant is positioned on the end face that armature contacts with magnet towards rotor axial, described temperature-sensitive dilatant is fixedly connected with armature, on described temperature-sensitive dilatant, be fixedly connected with heating member, in described bonnet, be provided with electric brush slip ring, on described armature and bonnet, be equipped with threading hole, in threading hole, be provided with electric wire, electric wire one end in described armature threading hole is connected with temperature-sensitive dilatant heating member, one end is connected with electric brush slip ring, electric wire one end in described bonnet threading hole is connected with electric brush slip ring, the other end is drawn bonnet outside.
By adopting technique scheme, armature is provided with temperature-sensitive dilatant, when brake motor is in power-off but rotor can not brake time, utilization is positioned at outside connecting line to inner heating member heating, described heating member conducts heat on temperature-sensitive dilatant, temperature-sensitive dilatant expands and promotes armature to bonnet motion until contact friction is braked rotor, design like this, can effectively avoid brake motor when this braking load can also dragging motor rotation etc. phenomenon, simultaneously, temperature-sensitive dilatant is located on armature, while making magnet hold armature, directly do not contact armature, avoided armature self sense magnetic, convenient and reliable, safety and stability, electric brush slip ring is set in bonnet, temperature-sensitive dilatant heating member line used is received on electric brush slip ring, while having avoided the temperature-sensitive dilatant on armature to rotate along with armature, thereby the line that heating member is used also rotates the phenomenon of knotting thereupon.
The utility model is further set to: described temperature-sensitive dilatant selects expansible graphite material to make.
By adopting technique scheme, temperature-sensitive dilatant adopts expansible graphite to make, expansible graphite have meet high temperature can moment volumetric expansion 150-300 doubly, good adsorptivity, resistance to pressure and self-lubricating property, when playing expanded by heating promotion armature and bonnet contact friction braking action, also can play effect lubricated, water suction.
The utility model is further set to: on described armature, include high performance friction pad, described friction pad is fixedly connected with and is located at armature on the surface that armature is used for contacting with bonnet.
By adopting technique scheme, on armature, be fixedly connected with the friction pad that high-quality friction material is made, make the friction between armature and bonnet larger, thus more stable to the braking of rotor.
The utility model is further set to: described brake motor housing and bonnet adopt casting aluminium material to make.
By adopting technique scheme, brake motor housing and bonnet adopt casting aluminium material to make, and compare with cast iron, and material is light, perfect heat-dissipating, and have good water proofing property.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of new brake motor of the utility model.
Structure chart when Fig. 2 is brake motor braking.
In accompanying drawing, 1. rotor; 2. spring; 3. magnet; 4. temperature-sensitive dilatant; 5. armature; 5a. armature threading hole; 6. friction pad; 7. bonnet; 7a. bonnet threading hole; 8. electric brush slip ring; 9. shell; 10. heating member.
Embodiment
A kind of new brake motor, comprise rotor 1, spring 2, magnet 3, temperature-sensitive dilatant 4, armature 5, friction pad 6, bonnet 7, electric brush slip ring 8, shell 9 and temperature-sensitive dilatant heating member 10, magnet 3 is adhesively fixed on rotor 1, when brake motor is worked, energising, magnet 3 holds armature 5 and leaves bonnet 7, spring 2 is compressed, not friction between armature 5 and bonnet 7, now rotor 1 rotates, when needs carry out skidding to brake motor, power-off, armature 5 is not held by magnet 3, under the effect of spring 2 elastic force, contact with bonnet 7, rub between the two rotor 1 is braked.
On armature 5, be adhesively fixed with temperature-sensitive dilatant 4, when brake motor needs power-off brake, because armature 5 sense magnetic, itself have that magnetic is inhaled mutually with magnet 3 or spring 2 elastic force diminish etc.
When reason armature 5 is not braked rotor 1 with bonnet 7 contact frictions, on the electric wire that is positioned at outside, be connected with plug, by plug, power, these are the prior art of electricity field, no longer describe in detail, temperature-sensitive dilatant heating member 10 heating powers, heating member 10 is thermistor, during energising, thermistor heating, heat is delivered on temperature-sensitive dilatant 4, temperature-sensitive dilatant 4 expands, now, the temperature-sensitive dilatant 4 expanding promotes armature 5 and leaves magnet 3 to bonnet 7 direction motions until contact with bonnet 7, now between armature 5 and bonnet 7, producing friction brakes rotor 1, on armature 5, be fixedly connected with the friction pad 6 that has or not the wear-resistant friction material of asbestos to make, make the friction between armature 5 and bonnet 7 larger, thereby the braking to rotor 1 is more stable.
In described bonnet 7, there is electric brush slip ring 8, on armature 5 and bonnet 7, there is threading hole, temperature-sensitive dilatant heating member 10 line used is received on electric brush slip ring 8 by the threading hole 5a on armature 5, the lead-in wire of electric brush slip ring 8 is drawn with power supply and is joined by the threading hole 7a on bonnet 7, design like this, make temperature-sensitive dilatant heating member 10 when rotating along with armature 5, electric wire can be because do not rotate and tie a knot thereupon.
