Description
Technical field
The present invention relates to mechanical damper, more specifically to a kind of mechanical damping of radial direction braking
Device.
Background technology
Damper, is divided into vibration damping energy dissipating and antivibration supports two major classes.
It is used for vibration damping energy dissipating in space flight, aviation, military project, firearms, automobile and other industries.Vibration damping energy dissipating
Damper is a kind of velocity-dependent damper without rigidity, installed in places such as engineering structures, quite
In " air bag " is mounted with, come interim in outside stimulus, damper absorbs and consumes to greatest extent
The energy of external drive input reaches the purpose of energy-eliminating shock-absorbing.From after nineteen seventies,
People start step by step to be converted in the Structural Engineerings such as building, bridge, railway these technologies, its hair
Exhibition is very rapid.
In nuclear power station, for damping supporting.Core level damper is a kind of to speed or acceleration response
Sensitive antivibration supporting arrangement, for protecting the key equipment or pipeline that are supported by.Damper is to equipment
Or the slow motion that the normal thermal expansion of pipeline causes does not work.Be subjected to sudden applied load (earthquake or
Pressure jump) when, damper has reformed into one and has been rigidly connected and carried out limiting displacement, and antivibration is reached with this
The purpose of support.Applied in large quantities in nuclear power station.
Damper can be divided into again according to a variety of applications：Spring-damper, hydraulic damper,
Pulse damper, rotary damper, wind damper, viscous damper and mechanical damper etc..
The mechanical damper for producing in the market, is, using ball screw structure, linear motion to be turned
Chemical conversion rotary motion, drives the rotation of inertial flywheel structure, and the mode taken flywheel braking is axially
Braking, causes that brake disc presses to Brake Block come real when Speed of Reaction Wheels increases using steel ball brake disc structure
Now brake, this mode of braking structure is more complicated, it is necessary to use steel ball, steel ball seat, flywheel, system
The more parts such as Moving plate cylinder, requirement on machining accuracy is higher, and most of part is required for IT6-IT7
Level machining accuracy, and part fitness is high, and assembly difficulty is big, high cost, and such damping
Device entire length is more long, and the length of chocking construction at least needs 100mm, is not easy to install.
The content of the invention
For disadvantages mentioned above present in prior art, radially braked it is an object of the invention to provide a kind of
Mechanical damper, mechanical damper simple structure of the invention, assembly precision requirement it is low, also reduce
The overall length of damper.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of mechanical damper of radial direction braking, including damper outer sleeve, outer sleeve includes inertia
Wheel cylinder and screw mandrel cylinder, flying wheel cylinder one end connection wire rod cylinder one end, flying wheel cylinder with diameter greater than screw mandrel
The diameter of cylinder, the flying wheel cylinder other end is provided with left end cap, also including right carrier head, connecting tube, ball
Nut, ball screw, flying wheel mechanism and drag ring, connecting tube are located at the inside of screw mandrel cylinder,
Its one end connects right carrier head, and right carrier head is located at the screw mandrel cylinder other end, the connection rolling of the connecting tube other end
Pearl nut, inside connecting tube, its another section is located at inertia to one section of ball screw through ball nut
Inside wheel cylinder, and flying wheel mechanism is met by being bonded, on the corresponding flying wheel cylinder inwall of flying wheel mechanism
It is provided with drag ring.
Described flying wheel mechanism includes flying wheel, spring, brake pad and guide post, and guide post is erect
In on flying wheel, brake pad is placed on guide post, and connects flying wheel by spring.
It is internal that described ball screw is fixed on flying wheel cylinder by bearing.
Described guide post has four pairs, averagely on flying wheel.
Described brake pad level is on every a pair of guide posts.
Described spring is in the middle of every a pair of guide posts.
In summary technical scheme, it is an advantage of the current invention that simple structure, eliminates brake disc
The parts such as cylinder, steel ball, steel ball seat, machining accuracy only needs IT8 or so, assembly precision to require also phase
Should reduce, it is cost-saved, and shorten damper entire length about 1/3, it is easily installed.
Brief description of the drawings
Fig. 1 is integrally-built main sectional view of the invention；
Fig. 2 is left sectional views of the Fig. 1 along A-A.
Specific embodiment
Technical scheme is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1, a kind of mechanical damper of radial direction braking provided by the present invention is and existing
Having technology identical is, equally also includes the outer sleeve 1 of damper, and outer sleeve includes flying wheel overcoat
101 and screw mandrel outer sleeve 102, one end connection wire rod outer sleeve 102 1 of flying wheel outer sleeve 101
End, the diameter with diameter greater than screw mandrel outer sleeve 102 of flying wheel outer sleeve 101, flying wheel outer sleeve
101 other ends are provided with left end cap 2, are not repeating herein.Unlike the prior art, the present invention
Also include right carrier head 3, connecting tube 4, ball nut 5, ball screw 6, flying wheel mechanism and rub
Ring 7 is wiped, connecting tube 4 connects right carrier head located at the inside of the screw mandrel outer sleeve 102, its one end
3, right carrier head 3 is located at the other end of screw mandrel outer sleeve 102, the other end of connecting tube 4 connection ball spiral shell
Female 5, inside connecting tube 4, its another section is located at 6 one sections of ball screw through ball nut 5
Inside flying wheel outer sleeve 101, and flying wheel mechanism is connected by key 12, ball screw 6 passes through
Two bearings 13 are fixed on inside flying wheel outer sleeve 101, outside the corresponding flying wheel of flying wheel mechanism
The inwall of sleeve 101 is provided with drag ring 7.
Incorporated by reference to shown in Fig. 2, described flying wheel mechanism includes flying wheel 8, spring 9, brake pad
10 and guide post 11, guide post 11 is erected on flying wheel 8, and brake pad 10 is placed on guide post 11
On, and flying wheel 8 is connected by spring 9, guide post 11 has four pairs, is averagely located at flying wheel 8
On, on every a pair of guide posts 11, spring 9 is located at every a pair of guide posts 11 to the level of brake pad 10
It is middle.
Operation principle of the invention is that right carrier head 3 pulls the side-to-side movement of ball nut 5, drives rolling
Ballscrew 6 rotates, and ball screw 6 drives flying wheel 8 to rotate by key 12, mounted in flying wheel 8
On spring 9, guide post 11, the concomitant rotation of brake pad 10, when the movement velocity of ball nut 5 increase
When big, ball screw 6 and the rotating speed of flying wheel 8 increase, and the centrifugal force of brake pad 10 gradually increases,
Spring 9 is pulled, is moved to drag ring 7 along the direction of guide post 11, produced when drag ring 7 is touched
Raw frictional force reduces rotating speed, so that the rotating speed of flying wheel 8 cannot continue increase, reaches braking
Effect.
