Description
Technical field
The present invention relates to mineral electromechanical equipment field, and in particular to one kind is long-acting to use temperature control friction coupling device.
Background technology
At present, the electromechanical equipment such as existing most of mining scraper machines, ribbon conveyer, to protect motor, motor is with subtracting
Fast machine engages automatically on startup, automatically terminates connection in overload, mainly uses fluid clutch or centrifugal friction clutch
Device.
Fluid clutch is locally to be filled with liquid medium in clutch inner chamber, when motor drives clutch to rotate, liquid
The turbine impeller blade of body medium impact clutch under the influence of centrifugal force, so as to drive output shaft rotation.Fluid clutch by
Cause oil or water expansion, boosting in typically using oil or water as the Transfer Medium of power, being also easy to produce high temperature in operation, cause to be arranged on
Fusible plug fusing on clutch outer member, oil, water leakage, ultimately results in shutdown, influences normal work, thus service life compared with
It is short.
Centrifugal friction clutch is to rely on the frictional engagement of centrifugal-block and clutch disk or separate and realize clutch, is made
With the clutch of the structure due to this body weight, brake pad and clutch disk instantaneous touch, therefore output shaft is easily caused because of impulsive force
It is excessive and be broken；In addition, because gas explosion burning-point is 305 DEG C, country's peace mark does regulation, the clutch surface that underground coal mine uses
Temperature must not exceed 200 ± 2 DEG C, and when existing centrifugal friction clutch overloads, surface temperature will be more than 400 DEG C, to prevent
Temperature exceeding standard, using disposable measure, once i.e. clutch surface temperature more than 200 DEG C, brake pad efflorescence immediately
After come off, cause clutch disposable.For these reasons, centrifugal friction clutch service life is also shorter.
First, the Chinese invention patent specification of the bulletin on the 18th of August in 2004 discloses one kind that the applicant applies and " rubbed
Erasing clutch " (application number 02241064.3, notification number CN2634180Y), the slip clutch, including final drive shaft, company
Connect disk, clutch hoop, output shaft, the internal spline of the terminal pad coordinates with the helical gear of final drive shaft one end, terminal pad it is cylindrical
All inclined-planes and the drag ring surface profiles being fixed on clutch hoop medial surface；Terminal pad passes through two external block plates of its both sides, interior
Compression spring positioning between block plate and outer block plate and interior block plate.When electric motor starting is run, the helical gear on final drive shaft
The spring force of compression spring between interior block plate and outer block plate is overcome to the axial thrust load of terminal pad internal spline effect, promotes terminal pad
Axial movement, the inclined-plane of terminal pad excircle is contacted friction with the drag ring of clutch hoop medial surface, drive clutch hoop and fixation
The output shaft rotation being connected on clutch hoop, realize power transmission.The slip clutch and above-mentioned existing centrifugal friction from
Clutch is compared, because being Mohs friction between rubbing surface, and with it is in light weight, frictional contact surface is big, contact impact is small, service life
The advantages that long.To make the helical gear on final drive shaft more quickly apply axial force to terminal pad, the slip clutch
Fan blade is uniformly arranged in the outer circumferential periphery of terminal pad, when being rotated so as to final drive shaft, the rotational resistance of fan blade turns terminal pad
It is dynamic to lag behind final drive shaft.But found in use, the rotational resistance of fan blade is insufficient to allow terminal pad to rotate and significantly lags behind main biography
Moving axis, terminal pad and final drive shaft cause the inclined-plane and clutch hoop medial surface of terminal pad excircle close to synchronous idle during startup
Drag ring contact friction force deficiency, and power transmit it is not sensitive enough.In addition, the slip clutch, to prevent temperature exceeding standard,
Measure use and disposable.
Secondly, on 07 06th, 2011, I carried out technology upgrading, the patent of invention of bulletin, frictional coupling once more
Device, application number 201110197843.1, open (publication No.) CN 102252047A, the friction coupler, including main transmission
Axle, frictional disk, clutch shell, internal spline adapter sleeve, make frictional disk axially position and by the device of axle spring pressure；During startup,
Friction, control frictional disk and clutch shell medial surface are contacted with clutch shell inner radial surface by brake pad under the influence of centrifugal force
Drag ring friction, realize power transmission；During overload, frictional disk and drag ring temperature arrising caused by friction, the liquid in frictional disk closed cavity
Body heating expansion, forces frictional disk to be separated with drag ring, realizes motor and the separation of load.This friction coupler, there is weight
The spies such as amount is light, smooth engagement, power transmit sensitive, big, the controllable coupling device surface temperature of contact friction force, long-acting can use
Point, overtemperature potential safety hazard is completely eliminated, require that high place uses especially suitable for temperature safety.But inside this coupling device
Interior helical teeth, single-contact, complex manufacturing technology, installation trouble, Master Cost cost is high, and caused coefficient of friction is small, to skill
Art requires very rigorous.
Therefore, the present invention develops on the basis of mainly solving more than currently available technology presence deficiency.
The content of the invention
Technical problem solved by the invention is to provide a kind of wedge type block double contact, and coefficient of friction is big, temperature-controlling system
Reliable, manufacture craft is simple, long-acting use temperature control friction coupling device easy for installation.
Based on above-mentioned purpose, technical problem solved by the invention is realized using following technical scheme：
A kind of long-acting temperature control friction coupling device, including half a coupler, splined shaft, drag ring, positioning spline, fixing bolt,
Inner spline housing, spline frictional disk, blowdown radiating valve, under the influence of centrifugal force, axial slip overcomes drawing to the operating mode wedge type block
The resistance of spring, left clutch, right clutch is set to be contacted with drag ring, spline frictional disk heating, temperature is transmitted to operating mode wedge type block, made
Liquid expansion in into operating mode wedge type block body, promotes piston to stretch out, and is moved after making operating mode wedge type block under being acted on extension spring, drag ring and a left side
Clutch, right clutch separation.
Further, the spline frictional disk contacts with drag ring for double-ring surface.
The invention has the advantages that frictional disk and drag ring double contact inside this patent, coefficient of friction is big, temperature control
Systematic comparison is reliable, and manufacture craft is simple, easy for installation, and manufacturing technology need not be especially rigorous, reduces material cost, thoroughly
High temperature safe hidden danger is relieved, reaches long-term use of purpose.
