Abstract
The utility model discloses a guide device of an electromagnetic brake comprising a guide plate. A guide column which is integrated with the guide plate is arranged on the guide plate and is of a square lug boss; the guide plate further comprises an extension part which can wrap armature iron and a work air gap end surface of a guide magnet and a brake plate end surface. The guide device of the electromagnetic brake can well reduce accumulated error, decrease dust entering the brake, improve brake effect, and extend the service life of the brake.
Description
Technical field
The utility model relates to a kind of electromagnetic brake element, especially a kind of guiding device of electromagnetic brake.
Background technique
Along with present science and technology development, society, the automation in each field that produces, lives, intelligent degree are more and more higher, every field such as society all require various products to have very high automation and intelligentized function, at present, electromagnetic brake is as desirable automation executive component, with micro motor in conjunction with deriving from into brake motor, be widely used in the automation mechanical driving systems such as a machine driving, electric wheelchair, storage control automatically, stage and theater machinery, automatic door, medical apparatus, stepper motor, play effects such as parking fast, safety brake.
Electromagnetic brake is as automation, the requisite element of intelligent industry, and it also will equally with other products will have stable performance except having its specific function.The armature of electromagnetic brake is iron, and the magnetic force that produces when field coil is switched on is with the armature adhesive, and the spring of this moment is compressed, the friction plate wheel is released and rotates freely with motor shaft, during the field coil outage, armature moves axially and finishes brake under the effect of spring force.Traditional electromagnetic brake, the carrier of its slip are by four hollow guide pillars, and four grooves of armature are enclosed within on these guide pillars, along the guide pillar over glaze to slip.
As shown in Figure 1 to Figure 3, the electromagnetic brake of the hollow guide pillar of existing employing exists following defective:
What (1) existing electromagnetic brake adopted is hollow guide pillar 5 guiding, because their relative position is unfixing, the cumulative error that is produced is big, will cause armature 2 planes and magnet case 1 end face not parallel, in the process of armature 2 actions, because the axial magnetic part that armature 2 is subjected to is disappeared at the resistance that hollow guide pillar 5 surfaces produce by armature, is actually the effective magnetic force that has reduced magnetic field, and braking moment is descended.
(2) because existing electromagnetic brake, there is most of part to be exposed in the circle, place, can cause dust to enter in the air gap between electromagnetic brake magnet case 1, armature 2 and the brake disc 3, thereby change relative permeability, influence the braking effect of electromagnetic brake.
(3) technology is made break now, because hollow guide pillar all is the many independent smallclothes of quantity, cumbersome during actual assembled, time-consuming, especially more difficult adjustment is even when adjusting the working gas gap of break.
The model utility content
The purpose of this utility model is in order to overcome technological deficiency recited above, a kind of guiding device of electromagnetic brake to be provided.
In order to solve technical problem recited above, the utility model is taked following technological scheme:
A kind of guiding device of electromagnetic brake is provided, includes positioning disk, described positioning disk is provided with the directional post that is designed to one with positioning disk.
Described positioning disk is provided with four directional posts.Described directional post is a square boss.
Described positioning disk also includes the extension component that can wrap up armature and magnet case working gas gap end face and brake disc end face.
The guiding device of the electromagnetic brake that the utility model provides, the design of positioning disk and directional post one, and also positioning disk also includes the extension component that can wrap up armature and magnet case working gas gap end face and brake disc end face, has the following advantages:
(1) a plurality of directional posts and the positioning disk of guiding device are designed to one, reduced machining error, thereby can guarantee that more armature is parallel with yoke body end face, thereby the action parallel to an axis of armature is moved, the side pressure of part side generation is on every side become very little, and it is parallel mobile can not hinder armature.
(2) the electromagnetic brake guiding device can wrap up armature and magnet case working gas gap end face and brake disc end face part, has reduced the air gap that enters of dust.Improve the break braking ability and increased the service life, reduced the rate of fault of break.
(3) because the guiding device of break is position and big or small point-device single unit system, so not only make break easy for installation, the more important thing is to need not the working gas gap adjustment, just can proper functioning.
The utility model guiding device can well reduce cumulative error, reduces dust and enters break, improves the braking effect and the working life of break.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.

Fig. 4 is the structural drawing of the electromagnetic brake of employing the utility model guiding device.
Fig. 5 is the structure drawing of device of the utility model and armature.
Fig. 6 is the device schematic representation of the utility model and armature.
Among the figure: 1. magnet case, 2. armature, 3. brake disc, 4. keep plate, 5. hollow guide pillar, 6. guiding device, 61. positioning disks, 62. directional posts, 63. extension components.
Embodiment
See also Fig. 4 to Fig. 6, as shown in the figure, electromagnetic brake includes and cooperates magnet case 1, armature 2, brake disc 3, keep plate 4 and the guiding device of installing 6, this guiding device includes positioning disk 61, positioning disk 61 is provided with four and is designed to the directional post 62 of one with positioning disk 61, and this directional post 62 is a square boss; Positioning disk 61 also includes the extension component 63 that can wrap up armature 2 and magnet case 1 working gas gap end face and brake disc 3 end faces.
Armature is provided with the square aperture that is complementary with square boss, after the guiding device assembling, the extension component parcel armature of positioning disk and the working gas gap end face and the brake disc end face of magnet case, armature moves on the square boss side, thereby can reduce the resistance of adhesive and release well, improve the performance of electromagnetic brake.
Described positioning disk and extension component thereof, directional post can use the plastic monoblock die-casting and molding technology to produce a plastics die sleeve, and the square boss that has four identical sizes on the die sleeve is made.
The New Guide Device that is applied to electromagnetic brake that the utility model provides can better partly lead to the armature of electromagnetic brake, makes break can better transmit braking force, and then improves the performance of break.
