Description
Technical field：
The utility model is related to brake technical fields, specifically, being related to a kind of double mute electricity loss brakes.
Background technology：
Electromagnetic brake is a kind of connector that master end torsion is communicated to passive side, can be according to the free knot of needs
It closes, cuts off or brake.Winding generates magnetic field after power-up, and armature is sucked back, while armature compression is fixed on the spring in iron core.It loses
When electric, winding charge, spring pops up armature, and armature will generate braking moment on frictional disk, and motor is made to stop.Electromagnetism dead electricity
Brake is a kind of when electromagnetism is detached from or is discharged, and so that friction system is generated frictional force by what spring pressed, and then generate system
A kind of dynamic brake.It can be used for machine driven system, realize fast with electric drilling match at a kind of novel braking motor
Speed parking and accurate positionin, can safety arrestment when power is off.Electromagnetic power-off brake is widely used in metallurgy, building, chemical industry, food
In the machinery such as product, lathe, printing, packaging, and the occasions such as (anti-danger) braking when power is off.This brake have it is compact-sized,
Easy for installation, wide adaptability, working frequency are high, are active in one's movements, brake the advantages that reliable, are a kind of ideal automated execution members
Part.
In the prior art, electromagnetic power-off brake still has some shortcomings, when powerless magnetic brake is braked, hollow spiral shell
Bolt generates friction with peripheral part, is also easy to produce noise so that existing electromagnetic brake does not adapt to some and required to noise
High occasion.
Utility model content：
The utility model overcomes the deficiencies of existing technologies, and provides a kind of double mute electromagnetic power-off brakes.
Technical problem to be solved in the utility model is just realized with following technical scheme：A kind of double mute electromagnetic dead electricity systems
Dynamic device includes the brake ontology formed via upper machine body and lower body, and the upper machine body and lower body are via hollow bolt
Flexible connection；The lower body inner cavity is equipped with the groove for placing rubber ring, and the groove is embedded in rubber ring and rubber
Cushion rubber and hollow bolt interference fit.
Preferably, the rubber ring is internally provided with several bloops for reducing noise, and the bloop is transversal
Face includes rectangle, circle, triangle.
Preferably, the outer diameter of the hollow bolt is 48~52mm.
Preferably, the groove internal diameter is 62~67mm, and the rubber ring thickness is 8~10mm.
Compared with prior art, the beneficial effects of the utility model are：
1, upper machine body and lower body are flexibly connected using hollow bolt, compared with prior art, reduce connecting component
Weight, to reduce effect of inertia of the electromagnetic power-off brake in braking process, to reduce upper machine body and lower body
The noise generated when dead electricity is braked；
2, it is interference fitted by being equipped with rubber ring and rubber ring and hollow bolt in lower body so that rubber ring and hollow
It is very close to each other between bolt, to which the hollow bolt generation that will not collide with electricity loss brake ontology is made an uproar in braking process
Sound.

Fig. 2 is location A structural schematic diagram in Fig. 1；
In figure：1~upper machine body；2~lower body；3~hollow bolt；4~groove；5~rubber ring；6~bloop.
Specific implementation mode：
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face combination is specifically illustrating and embodiment, furthers elucidate the utility model.
Embodiment 1：
As depicted in figs. 1 and 2, a kind of double mute electromagnetic power-off brakes, including formed via upper machine body 1 and lower body 2
Brake ontology, upper machine body 1 and lower body 2 are flexibly connected via hollow bolt 3；2 inner cavity of lower body is equipped with for placing rubber
The groove 4 of cushion rubber 5, groove 4 is embedded in rubber ring 5 and rubber ring 5 and hollow bolt 3 are interference fitted.
In the prior art, electromagnetic power-off brake still has some shortcomings, when powerless magnetic brake is braked, hollow spiral shell
Bolt generates friction with peripheral part, is also easy to produce noise so that existing electromagnetic brake does not adapt to some and required to noise
High occasion, the utility model provide a kind of double mute electromagnetic power-off brakes, using hollow bolt 3 by upper machine body 1 and lower machine
Body 2 is flexibly connected, and compared with prior art, is reduced the weight of connecting component, is being braked to reduce electromagnetic power-off brake
Effect of inertia in the process, to reduce the noise that upper machine body 1 and lower body 2 are generated when dead electricity is braked；By in lower machine
It is equipped with rubber ring 5 in body 2 and rubber ring 5 and hollow bolt 3 are interference fitted so that between rubber ring 5 and hollow bolt 3 without between
Gap, in braking process hollow bolt 3 will not collide with electricity loss brake ontology generate noise.
Specifically, the outer diameter of hollow bolt 3 be 50mm, 4 internal diameter of groove be 65mm, 5 thickness of rubber ring be 9mm, by
It is equipped with rubber ring 5 in lower body 2 and rubber ring 5 and hollow bolt 3 are interference fitted so that does not have between rubber ring 5 and hollow bolt 3
Have gap, in braking process hollow bolt 3 will not collide with electricity loss brake ontology generate noise.
Embodiment 2：
