Description
Technical field
The invention belongs to electromagnetic power-off brake technical fields, and in particular to a kind of arbitrarily to adjust rubbing surface gap
Electromagnetic power-off brake.
Background technology
Electromagnetic power-off brake be it is a kind of be powered separation, power-off brake electromagnetic brake, it is commonly utilized in general
On logical Y-series motor and in other transmission systems, the object for rotating and moving can be carried out being accurately positioned and anti-danger is made
Dynamic, which is widely used in the occasions such as oil, chemical industry, printing, packaging.Common electromagnetic power-off brake includes mainly magnetic
Several parts such as yoke, coil, spring, armature, brake disc and geared sleeve, operation principle are when the logical upper DC excitation electricity of coil
Stream, magnetic yoke body generate the pressure adhesive armature that D.C. magnetic field overcomes spring, so that armature is moved to yoke direction, displacement distance δ
The left and right (about 0.5~1mm), the Friction Disk Surface in brake disc and fastness also relieve pressure at this time, are moved up in geared sleeve
It is dynamic, it is in quick condition, the axis of motor is in rotation status；If giving coil blackout, the magnetic field of coil disappears, and armature is in bullet
It is moved to the direction of brake disc under the action of spring force, the rubbing surface for compressing brake disc surface generates moment of friction, reaches braking rotation
The effect of the motor shaft turned.This electromagnetic power-off brake mounting means is the horizontal installation of requirement motor, that is, require motor shaft with
Ground is parallel because installation is mobile very convenient on geared sleeve for brake disc in this way, all the time electromagnetic brake be all with
What this mode was installed.
But some occasions need the vertical installation of motor, what is come into being is the electromagnetism mistake of vertical installation in the prior art
Electric brake.But the electromagnetic power-off brake of vertical installation in the prior art, when electromagnetic brake is in non-brake situation
Under, armature is relieved to brake disc pressure, and brake disc is in the state floated, and brake disc at this time is under the effect of gravity
It is moved toward armature direction.In the state of in this way, brake disc can and then motor shaft rotates together when brake is not braked, and
Non-load friction is generated with armature, and since friction work can generate heat, can also accelerate the abrasion of friction plate in this way, shortens braking
The service life of device.In addition, the profit for the effect of electromagnetic power-off brake of vertical installation generates magnetic field to coil in the prior art
It is also not high enough with efficiency, lack the preparation configuration adjusted manually.Accordingly, it is desirable to provide a kind of new technical solution is given and is solved.
Invention content
Technical problem to be solved by the present invention lies in provide a kind of electromagnetism dead electricity that can arbitrarily adjust rubbing surface gap
Brake, the electromagnetic power-off brake is simple in structure, easy to operate, avoids brake disc in non-braking state due to itself weight
Force effect and with motor shaft rotation and and armature generate non-load friction, avoid the abrasion of friction plate, to improve brake
Device uses effect and the service life for extending brake.
To achieve the above object, the present invention provides the following technical solutions：A kind of electricity that can arbitrarily adjust rubbing surface gap

In being also installed on brake disc on the motor shaft of the secondary lower section of the friction, rank is installed on the motor shaft below the brake disc
Iron is installed on yoke on the motor shaft below the armature, and coil is installed in the yoke, and the yoke is rubbed with described
It is fixedly connected by mounting ring between wiping is secondary, and is also installed on the fastening for fixing yoke and friction pair in the mounting ring
Bolt has gap between the brake disc lower section and the motor shaft, air gap adjusting sleeve, and institute is installed in the gap
It states and is also installed on screw in air gap adjusting sleeve, end cap is also installed on the motor shaft below the air gap adjusting sleeve,
The end cap is fixed by fastening bolt and the yoke.
As optimal technical scheme, annular groove is machined in the yoke, the coil is installed in the annular groove
, and the coil is redundancy coil.
As optimal technical scheme, magnetoconstriction bar is also installed in the coil, magnetoconstriction bar one end is solid
It is scheduled in the coil, the other end is flexibly connected with the armature.
As optimal technical scheme, it is also installed on connector sleeve in the yoke, compression nut, institute are equipped in the connector sleeve
It states and is installed on rotary shaft on compression nut, the rotary shaft other end extends to outside the yoke, and is located at the rotary shaft
It is installed on rotary sleeve with the yoke junction, handle is also installed in the rotary shaft.
As optimal technical scheme, compressed spring, the compression are also installed in the rotary shaft in the connector sleeve
Spring is located at below the compression nut.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is used installs a gas additional in the lower section of brake disc
Gap adjusting sleeve and mounting ring, when assembly, is determined the working gas gap size of brake by the length of mounting ring, with air gap adjusting sleeve
Up and down adjustment brake disc up and down, (the secondary contact of discord friction above, armature of getting along well below connect when disk to be braked does not rub up and down
Touch), the screw in air gap adjusting sleeve is locked, even if air gap adjustment is completed, is then loaded on mounting ring and yoke, it is entire to pacify
Dress is accused and is completed, and when such brake, brake disc, air gap adjusting sleeve and brake disc are pushed down upwards under the action of armature spring
It does not contact, when brake guaranties (not braking state), armature moves under the action of electromagnetic force to the direction of yoke, braking
Disk held under gravity by it after the spline tooth slide downward of geared sleeve and the contact of air gap adjusting sleeve do not allow it after
Continuous slide downward, replys in pre-adjusted air gap, avoids the non-load friction of brake disc and armature, avoid friction plate
Abrasion, to improve brake using effect and the service life for extending brake；Annular groove is matched and redundancy coil
The effect of coordinating magnetoconstriction bar that can electromagnetic power-off brake be generated magnetic field to coil using using abundant, braking and
When；The compression nut being arranged in connector sleeve cooperation rotary shaft under compressed spring effect plays the effect of hand brake, thus into
One step improves the braking effect of electromagnetic power-off brake.
