The movable armature is further connected with a motor seat through a connection bolt and a nut. The connection bolt is also fixedly connected with the static magnet yoke which is composed of a static magnet yoke body, a compressed spring and a magnet exciting coil. A stainless steel gasket is arranged between the static magnet yoke and the movable armature, and is sleeved on the connection bolt. The double air gap high-low voltage low noise block type electromagnetic brake can effectively reduce working noise of a brake, and reduce power consumption of the brake.
Description
Technical field
The utility model relates to a kind of break technical field, is specifically related to a kind of pair of high low voltage low noise block of air gap formula electromagnetic brake.
Background technique
Existing block type electromagnetic brake generally all mainly is comprised of yoke and armature (containing the sassafras sheet that rubs) two large divisions, in yoke, be provided with excitation winding pole coil and brake compression spring, after the field coil energising, produce magnetic field, this magnetic field suction armature, armature is to the yoke moving linearly, and brake spring is compressed, be fixed on brake block on the armature along with armature moves together, brake block and brake disc break away from, and brake disc is free to rotate, and this moment, break was attracting state.After the field coil outage, magnetic field disappears to the attraction force of armature, and the brake compression spring automatically replies, promote armature and move to brake disc, spring force is close on the brake disc brake block, produces thus the sassafras braking moment of rubbing, force the brake disc stop motion, this moment, break was releasing state.This block type electromagnetic brake is installed on the outer rotor motor, and its braking response time, break temperature rise and brake noise are difficult to satisfy the needs of fast braking and low-noise outer rotor motor.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, a kind of a kind of block type electromagnetic brake that uses on the outer rotor motor that is useful in is provided, the utility model has reduced the operational noise of break effectively, and has reduced the power consumption of break.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of pair of high low voltage low noise block of air gap formula electromagnetic brake, by static yoke, moving armature and control terminal box form, described moving armature is by the moving armature body, brake block, brake mount connects to form successively, and be fixed on the moving armature body by the brake mount attachment screw, described moving armature also is connected with electric machine stand with nut by connecting bolt, described connecting bolt also is fixedly connected with static yoke, described static yoke is by static yoke body, Compress Spring, field coil forms, described Compress Spring is arranged in the described static yoke body, and be connected with described moving armature body, described static yoke body opposite side is provided with hand release, described field coil is arranged at described static yoke body interior central position, described control set of terminal box is provided with the Thin Stainless Steel packing ring in the top of described static yoke body in the gap between described static yoke and the described moving armature, and described Thin Stainless Steel packing ring is placed on the described connecting bolt.
Further, described field coil is coated with insulating resin.
The beneficial effects of the utility model are:
The utility model has reduced the impact sound of moving armature and static yoke when the break adhesive puts in place and motor and has been braked the moment brake block to the Strike note of brake disc, has effectively reduced the operational noise of break; Operating current when the break adhesive is kept is little, has both reduced the power consumption of break, the temperature rise when having reduced again the break operation, thus break can be worked in natural cooling situation; The air gaps that break has is so that the install and adjust of break is more convenient.This pair of low noise block type electromagnetic brake of the high low voltage of air gap.Be applicable to require fast braking and low noise workplace.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings

Number in the figure explanation: 1, brake disc, 2, brake block, 3, brake mount, 4, brake mount attachment screw, 5, static yoke, 6, moving armature, 7, connecting bolt, 8, nut, 10, the moving armature body, 11, Thin Stainless Steel packing ring, 12, static yoke body, 13, Compress Spring, 14, insulating resin, 15, field coil, 16, the manual release dress, 17, control terminal box, 18, electric machine stand, 19, the moving armature body.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to Fig. 1 and shown in Figure 2, a kind of pair of high low voltage low noise block of air gap formula electromagnetic brake, by static yoke 5, moving armature 6 and control terminal box 17 form, described moving armature 6 is by moving armature body 19, brake block 2, brake mount 3 connects to form successively, and be fixed on the moving armature body 10 by brake mount attachment screw 4, described moving armature 6 also is connected with nut and is connected with electric machine stand 18 by connecting bolt 7, described connecting bolt 7 also is fixedly connected with static yoke 5, described static yoke 5 is by static yoke body 12, Compress Spring 13, field coil 15 forms, described Compress Spring 13 is arranged in the described static yoke body 12, and be connected with described moving armature body 10, described static yoke body 12 opposite sides are provided with hand release 16, described field coil 15 is arranged at described static yoke body 12 inside center positions, described control terminal box 17 is arranged at the top of described static yoke body 11, be provided with Thin Stainless Steel packing ring 11 in the gap between described static yoke 5 and the described moving armature 6, described Thin Stainless Steel packing ring 11 is placed on the described connecting bolt 7.
Further, described field coil 15 is coated with insulating resin 13, and described insulating resin 13 has been strengthened the radiating effect of described field coil 15, and has eliminated the harmful effect that break produces when vibration.
The working principle of present embodiment is as follows:
When the break adhesive, the high low pressure modular converter at first provides the high voltage of magnet excitation, field coil 15 produces magnetic field, electromagnetic attracting force moving armature 6 is to static yoke 5 motions, and Compress Spring 13 is compressed under 19 effects of moving armature body, after moving armature body 19 is pressed onto Thin Stainless Steel packing ring 11, position limit switch sends the signal that armature puts in place, modular converter is changed immediately provides low voltage, and to keep the attracting state of break, motor can freely rotate.
When break discharges, field coil 15 outages, magnetic field disappears, the non-electromagnetic-force effect, Compress Spring 13 resets, and promotes fast moving armature 6 to brake disc 1 motion, and brake block 2 is pressed on the brake disc 1, frictional force produces braking moment, and motor is stopped operating, and reaches the purpose of braking.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
