Abstract
The invention discloses an ultrathin power-off brake. The ultrathin power-off brake comprises an electromagnet, a spring, a friction plate, a rotor plate, a stator plate and a coil, wherein when the rotor plate correlated to the electromagnet is not electrified, the friction plate is tightly pressed by means of the force of the spring and the rotor plate correlated to the electromagnet, so as to ensure that the friction plate generates certain friction force to provide brake effect; and when the radiation type coil is electrified, a magnetic field is generated to magnetize the rotor plate of the electromagnet, the magnetizing force is greater than the force applied on the rotor plate of the electromagnet by the spring, and the rotor plate of the electromagnet is attracted to the electromagnet end, so that the friction force between the friction plate connected with the rotor end of an external motor and the stator plate disappears, and the motor starts to rotate. According to the ultrathin power-off brake, the electromagnetic radiation principle is thoroughly understood and applied; and through starting from the materials and through winding the electromagnetic coil and enlarging the area of the rotor plate, the thickness of the existing power-off brake is decreased exponentially and then the application range of the power-off brake in multiple fields is enlarged.
Description
Technical field
The present invention relates to a kind of dead electricity brake. Especially be applied to dead electricity the brake field, particularly industrial robot in little space.
Background technology
Existing dead electricity brake, because the reason volume ratios such as its material, design principle are larger, is restricted in the occasion that much needs small size. The present invention is directed to above shortcoming and start with from the aspect such as material and electromagnetic radiation principle, development and Design again, has accomplished dead electricity brake small size, has widened its range of application.
Summary of the invention
The present invention institute, for the deficiencies in the prior art, providesOnePlant ultra-thin dead electricity brake, comprise: electromagnet, spring, friction plate, moving plate, stator, coil, the associated moving plate of electromagnet relies on spring strength and the associated stator of electromagnet that friction plate is compressed in cold situation, makes it produce certain frictional force, plays braking effect. When radial pattern coil electricity, produce magnetic field by the magnetization of electromagnet moving plate, and be greater than spring action in the power of electromagnet moving plate, electromagnet moving plate attracted to electromagnet end, between the friction plate that external motor rotor-end connects like this and stator, lost frictional force, motor starts to rotate.
Preferably, a kind of ultra-thin its coil of dead electricity brake and electromagnet are radially multi-turn winding, and electromagnetic radiation area strengthens 4 times, and by this principle winding, electromagnetic radiation area can continue to strengthen.
Due to described a kind of ultra-thin dead electricity brake coil and the change of electromagnet winding, the area of moving plate can at least strengthen 2 times, thereby realizes small size work.
Preferably, its moving plate of a kind of ultra-thin dead electricity brake adopts magnetic soft NiFe alloy material, and nickel content 30%～60%, by alloy element proportioning and corresponding technique, can control magnetic property, obtains the soft magnetic materials such as high magnetic conduction, permanent magnetic conduction, square magnetic. Its plasticity is high, and counter stress is more responsive.
The present invention, by deep understanding and utilization to electromagnetic radiation principle, starts with from material, is changed and is increased moving plate area by the winding to solenoid, makes existing dead electricity brake accomplish that thickness reduces at double, thereby has increased it in multi-field application.

Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail: a kind of ultra-thin dead electricity brake, by the winding to solenoid and increase moving plate area, thickness is reduced at double, increase its object in the multi-field scope of application thereby reach.
To achieve these goals, we disclose a kind of ultra-thin dead electricity brake, comprise: electromagnet (1), spring (2), friction plate (3), moving plate (4), stator (5), coil (6), it is characterized in that: the associated moving plate of electromagnet (1) (4) relies on the strength of spring (2) and the associated stator of electromagnet (1) (5) that friction plate (3) is compressed in cold situation, make it produce certain frictional force, play braking effect. When radial pattern coil (6) energising, producing magnetic field magnetizes the associated moving plate of electromagnet (1) (4), and be greater than spring (2) and act on the power of the associated moving plate of electromagnet (4), electromagnet closes linkage piece (4) and attracted to electromagnet (1) end, between the friction plate (3) that external motor rotor-end connects like this and stator (5), lost frictional force, motor starts to rotate.
In the winding of described coil (6), adopt along electromagnet (1) radial multi-ring and be wound around, electromagnetic radiation area strengthens 4 times, and by this principle winding, electromagnetic radiation area can continue to strengthen. Due to coil (6) and the change of electromagnet (1) winding, the area of moving plate (4) can at least strengthen 2 times, thereby realizes small size work.
Described moving plate (4) adopts magnetic soft NiFe alloy material, and nickel content 30%～60%, by alloy element proportioning and corresponding technique, can control magnetic property, obtains the soft magnetic materials such as high magnetic conduction, permanent magnetic conduction, square magnetic. Its plasticity is high, and counter stress is more responsive.
In use, the small and exquisite of the volume of described dead electricity brake own also optimized machine shape from image, and this point is significant in the manufacture of nowadays equipment high-intelligentization.
