Abstract
The utility model discloses a novel double structure electromagnetic brake which adds a heat insulation dish between the two electromagnetic brakes; a heat insulation dish slot and a heat insulation gap are opened on the heat insulation dish. Thus the electromagnet of the brake does not burn out because of the heat energy generated from the friction of the brake when a motor shaft braking, and the service life of the brake is prolonged.
Description
Technical field: the utility model relates to a kind of electromagnetic brake and particularly relates to a kind of Noval double-structural electromagnetic brake.
Background technique: the general existing double structure electromagnetic brake that uses is directly to be cascaded by two electromagnetic brakes, brake disc in the one break respectively with its on armature and the electromagnet on another break friction produce braking moment, be attached thereto the motor shaft braking thereby make, because brake disc and electromagnet directly rub, produce a large amount of heat energy, make the break temperature rise very high, greatly shorten the working life of break, even burn out coil in the electromagnet, cause whole break braking failure.
The model utility content: the purpose of this utility model will provide a kind of exactly, and break is when braking, and the break temperature rise is constant, the break long service life, and electromagnet coil can not burn out in the break, the Noval double-structural break of good braking effect.
Content of the present utility model is achieved like this: it comprises: break I, break II, and the bolt, packing ring, hub splines, break I, the II that connect the two contain armature respectively, brake disc, electromagnet, spring, bolt sleeve etc., break I and break II are serially connected, brake disc on break when braking break II respectively with its on armature and break I friction, it is characterized in that: between break I and break II, be provided with thermal insulating disc.
Thermal insulating disc is connected in the side of the break I between break I and the break II by bolt.
On thermal insulating disc, be provided with thermal insulating disc groove and insulation voids.
The form structure of thermal insulating disc is consistent with the break form structure.
The thermal insulating disc form structure is designed to circle, a kind of in the polygonal.
Thermal insulating disc adopts metallic material to make.
The utility model is owing to adopt the said structure use to have simple in structure; the double structure brake rubs with armature and thermal insulating disc respectively and makes it braking; the heat that braking produces is difficult for being delivered on the electromagnet; thereby effectively protected electromagnet working life, thereby the working life of also having improved break greatly.
Description of drawings: Fig. 1 is the utility model double structure electromagnetic brake structural profile schematic representation.
Fig. 2 be Fig. 1 along B-B to sectional view.
Among the figure: 1. thermal insulating disc groove, 2. thermal insulating disc, 3. armature, 4. brake disc, 5. electromagnet, 6. spring, 7. bolt, 8. hub splines, 9. through hole, 10. packing ring, 11. bolt sleeves, 12. insulation voids, break I, II.
Embodiment: as Fig. 1, the I of break shown in 2, II is sleeved on the motor reel by hub splines 8 with mating, at break I, be provided with through hole 9 around II and the thermal insulating disc 2 accordingly, general and the break I of the form structure of thermal insulating disc 2, the II form structure is consistent, with thermal insulating disc 2 usefulness bolts 7 via through holes 9 be loaded between break I and the break II by the side of break I, around thermal insulating disc 2, have thermal insulating disc groove 1, when break is braked, brake disc 4 on the break II respectively with its on armature 3 and thermal insulating disc 2 friction, produce braking moment, thereby make the axle braking that is connected with break.Because of on thermal insulating disc 2, being provided with insulation voids 12 and having thermal insulating disc groove 1; and certain air clearance is arranged between the electromagnet on the break I 5; make thermal insulating disc 2 can not pass on the electromagnet 5 because of the heat that the braking friction produces; and the heat energy that produces during electromagnet 5 work can distribute by the heat dam on the thermal insulating disc 21; thereby electromagnet 5 unlikely burning out have been protected effectively; thermal insulating disc 2 also is designed to circular or polygonal; the employing wear-resistant metal material is made, and has improved the working life of break greatly.
