It is mounted on an axle by axle sleeve, stator or installing plate are fixed on wall.In the state of not being powered to magnet coil, armature leads to
Torsion spring after overcompression pushes down rotor, and rotor is sandwiched in armature and installing plate, and axle is entered by produced frictional force
Row braking and holding.In this case, certain space is kept between stator and armature.When the magnet coil of stator interior leads to
When electric, magnetic field will be produced, magnetic circuit is formed between stator and armature, stator overcomes the compression stress of torsion spring and attracts armature, is held in the mouth
Iron is in fairlead top offset, and space disappears between stator.Meanwhile, space is produced between rotor and armature turns into free state, and
Rotary shaft is released.
It is existing to be had the disadvantages that without excitation brake：
One：Usually need to adjust rotary shaft position under power failure state in commissioning device, it is necessary to temporarily open brake, pass
System is without excitation brake without this function.
Two：When running into urgent special circumstances, it is necessary to temporarily open brake, tradition is without excitation brake without this function.
Utility model content
The utility model purpose be to provide it is a kind of with release lever structure without excitation brake, solve prior art and deposit

It is preferred that, the flexible member is spring.
It is preferred that, the spring is torsion spring.
Further, at least one ball recess is respectively processed in the release lever position relative with the armature,
Steel ball is set in the ball recess.
It is preferred that, 2 ball recess are respectively processed on the release lever position relative with the armature.
Further, increase deformable rubber sleeve on the fairlead and push down the release lever.
The beneficial effects of the utility model are：
Be provided with the plant equipment or device of no excitation brake due to debugging and it is other it is urgent in particular cases, it is necessary to
Temporarily open without excitation brake, the utility model increases a release lever, and the release lever is simple in construction, former using lever
Manual releasing is managed without excitation brake, flexible movements, and with low cost, economic benefit protrusion, functional requirement has been fully met.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the utility model sectional view.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
As shown in figure 1, the utility model disclose it is a kind of with release lever structure without excitation brake, including stator 1,
Armature 3, fairlead 4, rotor 5, axle sleeve 6, release lever 7 and installing plate 8, the installing plate 8 are arranged on back end cover for motor 10, institute
State axle sleeve 6 to be fixed on motor shaft 11, the rotor 5 is arranged on the axle sleeve 6, and the rotor 5 is arranged on the installing plate 8
Between the armature 3, the stator 1 is arranged on the other end of the armature 3, the stator 1 and the back end cover for motor 10
Between be provided with multiple fairleads 4, the stator 1 is provided with groove, and flexible member 2 is provided with the groove, the flexible member 2
One end is contacted with the armature 3, is provided between the armature 3 and the installing plate 8 on release lever 7, the release lever 7
Mounting groove (being not drawn into figure) is set, and the mounting groove is stuck on two fairleads 4, and the release lever 7 can freely be put
It is dynamic not fall out again.
In the state of not being powered to the internal electro-solenoid of stator 1, armature 3 is pushed down by the flexible member 2 after compression to be turned
Son 5, rotor 5 is sandwiched in armature 3 and installing plate 8, by produced frictional force axle sleeve 6 and motor shaft 11 are carried out braking and
