Description
Technical field
The present invention relates to a kind of electromagnetic mechanism for being used to brake.It is more particularly related to a kind of electromagnetism card slot type
Brake.
Background technology
The brake of in the market is that have to make moving component or movable machinery slow down, stop or keep the functions such as halted state
Device, be the machine components for making movement parts in machinery stop or slow down, be commonly called as brake, lock.Brake is main by frame processed, system
Moving part and manipulation device etc. are constituted.Some brakes are also equipped with the automatic regulating apparatus in brake component gap.In order to reduce brake force
Square and physical dimension, brake are commonly mounted on the high speed shaft of equipment, but the higher large scale equipment of security requirement should then be filled
On the slow-speed shaft close to equipment working portion.
Such a motor has the disadvantage that：First, moment of torsion is small, and conventional electromagnetic brake structural is friction catch structural principle,
By adding friction plate and realizing friction catch being provided between the iron core end face of winding and movable iron plate, this structure braking is turned round
The magnetic field intensity that square is depended primarily on produced by winding, magnetic field intensity is bigger, and braking torque is bigger, and magnitude of field intensity is depended on
The number of turns of winding enamel-covered wire, because spatial volume is limited in motor, therefore this structure produce magnetic field intensity it is smaller enter
And braking torque is smaller；2nd,
Volume is big, weight is heavy, cost is high, and to meet motor braking torque demand, electromagnetic brake is needed by increasing magnetic
Field intensity increases braking torque, therefore corresponding electromagnetic brake volume more than winding number of turns is larger, weight weight, cost are high；
3rd, short life, conventional electromagnetic brake relies on friction plate friction catch, the longevity for the electromagnetic brake that the abrasion of friction plate makes
Life is shorter, and the continuous effect of attrition braking torque of friction plate and sensitivity；4th, energy consumption is more, temperature rise is big, electromagnetic braking
Device is under normal released state, and the electric energy that heating in winding is consumed is more, and temperature rise is big.

It is characterised by, including iron core, the wound around coil on the outside of the iron core, the interior rotational installation lead ring of iron core, lead ring periphery opens up groove, groove
Rotational installation moving block in brake block, the lead ring is inside slidably inserted into, the periphery of moving block is provided with recess, the periphery of the lead ring
Provided with extension spring, extension spring inner ring props up brake block and stretched into recess, the iron core end face mounting flange, and the axis of cone is fixed on ring flange
And screw, the axis of cone and screw both pass through and be cased with spring on stretching ring flange, the screw extension, and the ring flange passes through spiral shell
Silk is separated on iron core end face, is opened up on the brake block in hole, the axis of cone patchhole, brake block detaches recess.
Preferably, the iron core is to set square groove, the braking on the trisection posistion on annular shape, its end face
Block is located in square groove, and its periphery also opens up a circle groove, and the coil is wrapped in the groove of iron core.
Preferably, the lead ring is annular shape, and its periphery opens up and three grooves are opened up in a circle groove, groove, three grooves
Position it is corresponding with the square groove on iron core.
Preferably, the moving block is toroidal, and its outer Monday circle, which is opened up, angularly opens up six recesses, the center
Open up square through hole.
Preferably, the brake block is made up of the square and anterior rectangle at rear portion, and its rear portion is obtained on square
Hole is opened up, anterior rectangle width is less than the square length of side at rear portion.
Preferably, three axis of cone and three spiral shells are angularly fixed on the same radial distance in the edge of the ring flange
Silk, and the axis of cone and screw are spaced from each other installation.
The present invention at least includes following beneficial effect：The present invention by electromagnetic action due to controlling brake block to brake, therefore
The magnetic field intensity needed is smaller, greatly reduces coil turn, so as to reduce brake volume, weight and cost；Due to utilizing system
The motion block strength of materials itself is braked, therefore braking torque is big, and sensitivity is high；Because brake block and moving block are from high intensity rigidity
Material, therefore material deformation is few, long lifespan；Because the number of turn of coil is few, therefore electric energy loss and all few, the brake temperature that generates heat
It is low.
Further advantage, target and the feature of the present invention embodies part by following explanation, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
