Description
Technical field
A kind of electromagnetic power-off brake is the utility model is related to, more particularly, to a kind of electromagnetism dead electricity system for being applicable braking door
Dynamic device.
Background technology
Electromagnetic power-off brake：It is the external half-wave rectifier of brake, single-phase alternating current is rectified into direct current.After power-up around
Group produces magnetic field, and armature is sucked back, while armature compression is fixed on the spring in iron core.During dead electricity, winding charge, spring will be held in the mouth
Iron ejects, and armature will produce braking moment on the disc brake rotor, motor is stopped.
At present, door is being braked in use, setting position usually occur reaches the problem of not accurate.The reason for this problem one
Aspect is that braking door equipment configuration is uncoordinated, is on the other hand that the electromagnetic power-off brake loss of excitation linkage used is poor.Due to existing
Linkage between the armature and brake disc of some electromagnetic power-off brakes is poor, the electromagnetism dead electricity braking of braking door brakes
Device, make just on braking door to slow down or in most short distance stop；Retaining element and the friction on rotate element surface
And usually occurs the problem of setting position braking difference in the case of caused braking moment linkage difference.
Utility model content
The purpose of this utility model is to provide a kind of electromagnetic power-off brake for being applicable braking door, solves what braking door was equipped with
The problem of electromagnetic power-off brake optimization uses.
Technical scheme is used by the utility model solves its technical problem：
A kind of electromagnetic power-off brake for being applicable braking door, including installation bolt, armature, yoke assembly, brake disc, installation
Plate, geared sleeve, it is characterised in that：Magnet coil group is provided with yoke assembly, the side gap setting of magnet coil group has
Armature, the side of armature are provided with the brake disc for being equipped with friction plate group, and the side of brake disc is provided with installing plate, in yoke assembly
The top of installing plate is provided with installation bolt, the lower left side of armature is provided with back-moving spring, in back-moving spring and geared sleeve
Between be provided with gap, described geared sleeve, which is provided with, resets jacking block, what described resets jacking block and geared sleeve were integrated.
It is smooth in order to link, and reduce the abrasion of yoke assembly and geared sleeve.Positioned at the yoke for resetting jacking block top
Components are provided with a reset movable chamber.
For stable connection, involute outer spline set is connected with described brake disc.
Beneficial effect：Jacking block is resetted by being provided with back-moving spring and geared sleeve, so as to ensure that the dead electricity of electromagnetic brake
Closure obtains the electric braking opened and realize braking door precise positioning.Meanwhile connection involute outer spline set can in brake disc
Ensure and motor shaft is concentric installs.Rotation produces the motor shaft caused by radial displacement error when can avoid the armature from installing at a high speed
Winding degree and beat, reduce the operation of the repetition point position control of operation, reduce working strength.
Below with reference to drawings and examples, the utility model is described in detail.

It is smooth in order to link, and reduce the abrasion of yoke assembly and geared sleeve.Positioned at the yoke assembly 3 for resetting the top of jacking block 10
A reset movable chamber 11 is provided with point.Involute outer spline set 12 is connected for stable connection, in described brake disc 4.
Jacking block is resetted by being provided with back-moving spring and geared sleeve, so as to ensure that the dead electricity of electromagnetic brake closure or obtain electric
Opening realizes the braking of braking door precise positioning.Involute outer spline set is connected in brake disc simultaneously can ensure and motor shaft
Installation with one heart.The motor shaft caused by radial displacement error when can avoid the armature from installing winding degree caused by rotation and partially at a high speed
Pendulum, reduces the operation of the repetition point position control of operation, reduces working strength.
Embodiment above is only that preferred embodiment of the present utility model is described, not to the utility model
Scope be defined, on the premise of the utility model design spirit is not departed from, this area ordinary skill technical staff to this
The various modifications and improvement that the technical scheme of utility model is made, the guarantor that claims of the present utility model determine all should be fallen into
In the range of shield.
The utility model is not directed to partly same as the prior art or can realized using prior art.
