Abstract
The utility model relates to a brake electromagnet with a single shell and double magnetic circuits, which structurally comprises a shell, a gag bit, an electromagnetic coil and a brake spring, wherein the gas bit comprises two semicircular piece sheets, and a magnetic isolation layer is arranged on the symmetrical center line of the shell. In the brake electromagnet, the shell is divided into two bodies in a magnetic isolation state, thereby forming the structure that the electromagnet has the single shell and the double magnetic circuits, which belongs to a double brake body structure in the complete significance, so that magnetic lines of force generated by two electromagnetic brake bodies after being electrified can not influence each other by the conduction function of the shell, thereby avoiding the mutual influence of the magnetic lines of force in the magnetic circuits of the shell, and ensuring the stability of the magnetic action of the two electromagnetic brake bodies and the stability of the braking function of a brake.
Description
Technical field
The utility model relates to the used electromagnet of a kind of break, and specifically a kind of disk type braker is with mono-hull double magnetic circuit Breake Electromagnet.
Background technique
The Breake Electromagnet that disk type braker is used comprises parts such as housing, armature, electromagnetic coil and brake spring, through with the combining of brake disc, constitute complete disk type braker, be used in the braking of rotating machinerys such as lift machine.Because the standard code of elevator industry takes place for preventing fortuitous event, must dispose dual brake and brake.And manufacturer just designs the disk type braker of on a break, realizing two brake body braking functions for reducing the number of configured and the cost of break, so just can under the situation that does not increase configuration, satisfy the requirement of industry specified standard.Its concrete structure is exactly on the Breake Electromagnet of a disk type braker; Armature is processed two independently semicircular lamellar bodies; In housing, divide pack into two or four symmetrically arranged electromagnetic coils; To control the action of two armature respectively, can in a break, form two independently electromagnetic system kinetoplasts thus.
Although this structure can form the structural type of two electromagnetic system kinetoplasts, because two electromagnetic system kinetoplasts are that shared same housing forms magnetic loop, promptly have the shared problem of magnetic circuit.And the shared structural type of this magnetic circuit will inevitably produce harmful effect to the magnetic force that two electromagnetic system kinetoplasts are produced, and then has influence on the braking action effect of break.
The model utility content
The purpose of the utility model just provides a kind of disk type braker with mono-hull double magnetic circuit Breake Electromagnet, to solve two shared housings of electromagnetic system kinetoplast to harmful effect that magnetic force was produced.
The utility model is achieved in that a kind of mono-hull double magnetic circuit Breake Electromagnet, comprises housing, armature, electromagnetic coil and brake spring, and said armature is two semicircular lamellar bodies, on the symmetrical center line of said housing, is shaped at a distance from magnetosphere.
Slotted on the symmetrical center line of said housing, said is to be welded on formed interlayer body in the said slit with NULL at a distance from magnetosphere.
On the said gross section in the middle of magnetosphere is arranged on said housing.
One group of electromagnetic coil is housed in said housing.
Symmetrically arranged two groups or four groups of electromagnetic coils are housed in said housing.
The utility model makes the housing of Breake Electromagnet form two body structures at a distance from magnetic state, thereby has constituted the electromagnet structure of mono-hull double magnetic circuit through the setting at a distance from magnetosphere.The electromagnet structure of this mono-hull double magnetic circuit belongs to the two brake body structures on a kind of complete meaning; Promptly the magnetic line of force that after energising, produced of two electromagnetic system kinetoplasts can not have influence on the other side through the magnetic conduction effect of housing; Just can avoid the magnetic line of force influencing each other in housing magnetic circuit section thus, guarantee magneto motive stable and break braking action stable of two electromagnetic system kinetoplasts.

Embodiment
As shown in Figure 2, the armature 2 in the utility model is two semicircular soft iron magnetic conducting plate body structures, has the jack hole that joins with housing on the armature surface.Like Fig. 3, shown in Figure 4, on the symmetrical center line of the housing 1 of discoid band center hole, saw out one and slip gap, form a slit, bottom land can be concordant with the bottom land of coil groove on the housing 1; And then with full welds such as NULL such as copper material or stainless steels in this slit, form at a distance from magnetosphere 5.Also can housing 1 be broken off from centre symmetry line is whole, integral solder NULL on the cross section of breaking off makes the housing 1 welding assembly of two halves form a complete housing, and this is the separated magnetosphere 5 on the housing 1 at a distance from the magnetic face of weld.
As shown in Figure 1, in above-mentioned housing 1, be respectively charged into electromagnetic coil 3 and brake spring 4 etc., on buckle closure, after two symmetrically arranged armature 2,, penetrate hollow bolt 6 in a side of armature 2, hollow bolt 6 is threaded in the jack hole of housing 1; Side at housing 1 penetrates construction bolt 8, and construction bolt 8 can be locked on the casing of lift machine after from the core hole of hollow bolt 6, passing.
The brake disc 7 that is connected with the spindle nose key of lift machine is positioned at the outer side surface of armature 2, and the axle sleeve on the brake disc 7 is inserted in the core hole of this Breake Electromagnet.Form the disk type braker of mono-hull double magnetic circuit thus.
The one group of electromagnetic coil 3 of in housing 1, both can having packed into is to carry out the adhesive effect to two armature 2; Also can be by usual manner, in housing 1, pack into symmetrically arranged two groups or four groups of electromagnetic coils 3 are with the adhesive of respectively two armature 2 being carried out separately.
