The threaded hole that the positioning screw matches, since the often circle tooth of screw thread is away from constant, user only needs to stir armature peripheral edge
Ratchet so that armature is rotated, can be to armature and excitation according to positioning screw by the through hole number on the outside of armature
Main gap between iron core carries out accurate adjustment and control, in friction plate, brake disc when being worn thickness change, also can
Enough adjustment that adaptability is flexibly carried out to the main gap in the utility model carry out essence so as to fulfill to the main gap of brake
The purpose really regulated and controled.The utility model keeps the energization of field core under normal conditions, and armature is drawn to the absorption of field core direction,
Armature drives spring block to be moved, so that tripping spring is in compressive state, while armature drives frictional disk combination
It is moved on main shaft so that frictional disk, which combines to be separated between brake disc, to be come.When needing braking, cut off to field core
The energization of core, adsorption capacity between field core and armature disappear, under the elastic reset power effect of tripping spring by armature with
It is separated between field core while pushes frictional disk combination to brake disc direction so that frictional disk combination is close to braking dish cart
Braking rapidly and efficiently is realized in face.
Preferably, the spring housing and sealing sheath thread fitting.Ensure protective capability of the sealing sheath to main shaft one end,
Improve sealing performance.
Preferably, the protective cover being fixed on outside the spring housing is further included, the protective cover is located at sealing sheath and shell
Between.This brake inside equipment is protected by protective cover, protective cover concrete structure is unlimited, can play protection physics
The effect of damage.
Preferably, several locating parts are set between the protective cover and shell, several locating parts are circumferentially equal along main shaft
Even distribution.Enclosure location is determined by locating part, the shell of field core easily can be supported locating part and carried out by when installation
Setting improves comfort level during the utility model dismounting.
Preferably, the locating part is nut.
Preferably, the skeleton of the frictional disk combination is made by aluminum alloy materials.Frictional disk bone of the prior art
Frame is all using casting structure, and weight weight, inertia are big, inconvenient when being easy to cause low speed operation during being mounted directly use
It effectively disengages, causes brake disc wear serious, also result in a large amount of fevers.And preferred aluminum alloy materials are as friction in this programme
The skeleton of disk combination can substantially reduce the abrasion to brake disc, reduce abrasion fever.It can be in the vertical installation of brake
Free floating when low speed is run.
Preferably, O-ring seal is set on the contact surface of the brake disc and spline housing.Spline gaps can cause operation to make an uproar
Sound, this is the problem of being difficult to avoid that in conventional spline fit structure, therefore this programme is being made by the setting of O-ring seal
After Moving plate is prepared with spline package, O-ring seal is compressed, and eliminates the loosening that spline gaps are brought, it is suppressed that rotating operation
When spline gaps generate noise.
The utility model compared with prior art, has the following advantages and advantages:
A kind of power-off brake electromagnetic brake of the utility model can carry out the main gap between armature and field core
Accurate adjustment and control in friction plate, brake disc when being worn thickness change, also can flexibly carry out main gap
