Abstract
The utility model discloses an electromagnetic brake with the function of noise reduction, which comprises a magnetic conductor, an armature, a friction disk and a friction plate which are mounted by matching, a notch is provided on an end surface of the magnetic conductor contacted with the armature, elastic materials are contained in the notch, the end surfaces of the elastic materials project from the end surface of the magnetic conductor; a circular arc groove is machined on the excircle surface of a brake disc, and a spring is arranged in the groove. The electromagnetic brake provided by the utility model can effectively eliminate the noise generated when the armature attracting, can eliminate the vibration sound generated when the friction disk works to rotate, and can reduce the friction noise of the coupling part generated by the friction disk when the brake is braking.
Description
Technical field
The utility model relates to a kind of electromagnetic brake, relates in particular to a kind of electromagnetic brake with noise reduction noise reduction function.
Background technique
Electromagnetic brake is contained in the equipment as executive component commonly used, the action that it produces braking or discharges.During braking, the friction plate that armature moves axially rotation produces surface friction drag, and the running shaft of equipment is stopped fast; During release, armature disappears to the surface friction drag of friction plate, and transmission shaft drives friction plate and rotates freely under the motivational drive of motive force equipment.
As Fig. 1, the field coil of traditional electromagnetic brake gets the electromagnetic force that produces when electric, and the armature quick traction is come, and the end face of armature and magnet case bumps, because armature and magnet case all are firm parts, can send when their collide clear and melodious " " sound; Have, the working gas gap of electromagnetic brake all requires very little again, even in break releasing state (armature is by adhesive), its friction plate that discharges owing to there is little vibration, still can send noise because of vibration when high speed rotating; The friction noise that friction plate and its mating plate can send when braking.
Though the common electrical magnetic brake can keep its braking and release function, the action of its braking and release can produce noise, just because of the existence of these noises, under the higher environment of a few thing conditional request, this electromagnetic brake can not use.The detector of some in medical equipment for example, when patient was checked, if there is higher noise to exist, this not only made patient that manic sense is arranged, and also can doctor's attention be exerted an influence, and very influences the doctor patient is accurately judged.
The model utility content
The purpose of this utility model is in order to overcome technological deficiency recited above, a kind of electromagnetic brake with noise reduction noise abatement to be provided.
In order to solve technical problem recited above, the utility model is taked following technological scheme:
The utility model provides a kind of electromagnetic brake with noise reduction noise reduction function, include and cooperate magnet case, armature, friction plate and the friction plate of installing, with offer notch on the contacted magnet case end face of armature, be equipped with elastic material in the described notch, the end face of described elastic material protrudes the magnet case end face.
As a kind of preferred version, on the magnet case end face, offer several notches, and in each notch ccontaining elastic material.
Described elastic material is an O type rubber ring.
Imbed wherein by processing notch on the magnet case end face and with elastic material, make the end face of elastic material expose the magnet case end face, quick armature when the field coil energising of break, the armature end face bumps with the elastic material end face earlier, plays sound deadening when reaching the break adhesive.
As a kind of more excellent scheme, process arc groove on the periphery of described friction plate, in groove, be mounted with spring.
Described groove is around whole circumference, and described spring is wrapped in the groove.Described arc groove is band R type arc groove.Spring is wrapped on the R type arc groove of friction plate, and is engaged with the round hook of both ends of the spring.
By the mode of processing arc groove and settling spring on the periphery of friction plate, the chatter that makes friction plate produce when high speed rotating can be eliminated, and break is when braking, and the frictional noise that friction plate and its mating plate produced can be lowered.
The electromagnetic brake that the utility model provides, the noise that produces in the time of can eliminating the armature adhesive effectively, the chatter that produces when eliminating friction plate adjustment rotation and the frictional noise that reduces break friction plate and generation of its mating plate when braking.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the structural drawing of traditional electromagnetic brake.
Fig. 2 is the structural drawing of electromagnetic brake of the present utility model.
Fig. 3 is the structural drawing of friction plate of the present utility model.
Fig. 4 is the structural drawing of magnet case of the present utility model.
Among the figure: 1. magnet case, 2. armature, 3. friction plate, 4. friction plate, 5.O type rubber ring, 6. spring.
Embodiment
See also Fig. 2 to Fig. 4, as shown in the figure, electromagnetic brake includes and cooperates the magnet case of installing 1, armature 2, friction plate 3 and friction plate 4, with offer several notches on the contacted magnet case end face of armature, in notch, be equipped with elastic material, this elastic material is an O type rubber ring 5, this O type rubber ring 5 is imbedded respectively in each notch, and make the end face of O type rubber ring 5 protrude magnet case 1 end face, when the field coil of magnet case 1 is switched on, the electromagnetic traction power that produces spurs armature 2 fast and draws close to magnet case 1 end face, because magnet case 1 end face is equipped with the O type rubber ring 5 of protrusion, before being contacted with magnet case 1, armature 2 contacts earlier with O type rubber ring 5, so armature 2 can be subjected to the elastic buffer of O type rubber ring 5, and the noise that has produced when so just having eliminated armature 2 by adhesive.A band of processing R type arc groove on the periphery of friction plate 3, this grooved ring is around whole friction plate cylindrical circumference, spring 6 is wrapped on this R type arc groove, the round hook at spring 6 two ends is engaged, by this structure, can eliminate friction plate 3 under the break releasing state during high speed rotating, the noise that produces owing to vibration; Also can reduce break effectively when braking, the frictional noise that friction plate 3 and its mating plate (friction plate 4) are produced.
