Abstract
The utility model is related to drive shaft couples driving, power drive technology field, specifically a kind of soft start permanent magnetic coupling.Inactive state, is located at position L1 between permanent magnetic disk and inductor.During electric motor starting, the induced field formed between big rotating speed official post permanent magnetic disk and inductor is maximum.Induced magnetic field force is mutually exclusive.Mutually exclusive power is more than the power that permanent magnetism backboard attracts each other with driving magnet.So as to promote inductor to move axially to L2.Inductor rotating speed is gradually increasing, and speed discrepancy reduces, and magnetic induction force reduces, and permanent magnetic enhancing, permanent magnetic pulls gap between the two to taper into, and the moment of torsion increase of transmission, permanent magnet faster rotational speed finally reaches rated speed.Beneficial effect is that inductor makes full use of the magnetic line of force relative to permanent magnetic disk symmetric configuration, transmits the efficiency high of moment of torsion；Using the change between permanent magnetic and induced magnetism with speed discrepancy, the purpose of soft start is realized, soft start effect good advantage high with transmission efficiency.
Description
Technical field
The present invention relates to drive shaft couples driving, power drive technology field, specifically a kind of soft start permanent magnetism coupling
Clutch.
Background technology
Existing motor is typically using directly initiating, and electric motor starting causes electric current excessive, influences the normal operation of miscellaneous equipment,
The serious safety for possibly even jeopardizing motor and transformer.
Traditional permanent magnetic coupling, drive disk and be relatively-stationary by the position of drive disk.
The purpose of soft start can not be played.
CN205178839U is pointed out：All it is the double magnet disk knots of two-conductor disk in existing known delaying type magnetic coupling
Structure, the regulation of magnetic coupling intensity is the axial magnetic moving magnet disk produced in magnetic coupling, and displacement is short (logical
Often only 3-5 millimeters, coupling strength regulation also non-progressive, and time delay is short, carryover effects are very limited, for big used
Amount heavy load equipment can not produce soft start effect, and the one side of magnet has only been used in the coupling of magnet disk and conductor disc in its structure,
And another side is closed the magnetic line of force with magnetic conductive steel plate, the magnetic coupling performance of permanent magnet only make use of half.Carryover effects are not obvious,
Delay cushioning effect is played in startup stage to load equipment so as to not reach.
The content of the invention
For the technical problem mentioned in the prior art, the present invention provides a kind of soft start permanent magnetic coupling.
The present invention is achieved in the following ways：
A kind of soft start permanent magnetic coupling, mainly by load shaft flange (1), inductor (17), driving magnet (7), permanent magnetism

Between slide；Two groups of inductors (17) are relative to permanent magnetic disk (9) symmetric configuration；One of which inductor (17) is wrapped in described half
In closed area.
The present invention utilizes electromagnetic induction action principle：
In the inactive state of the present invention, it is located between permanent magnetic disk (9) and inductor (17) in initial position L1, both skies
Gas gap is minimum spacing L1.
After electric motor starting, the rated speed of motor, now, inductor are quickly reached with the permanent magnetic disk (9) of motor connection
(17) firm starting state is in, huge speed discrepancy causes the induced field formed between permanent magnetic disk (9) and inductor (17) most
Greatly.Induced magnetic field force is mutually exclusive.
The magnetic force attracted each other has been produced between permanent magnetism backboard (4) and driving magnet (7) on inductor (17).
At the beginning of electric motor starting, the mutually exclusive power of induced field is more than permanent magnetism backboard (4) and mutually inhaled with driving magnet (7)
The power drawn.So as to promote inductor (17) to move axially outward, position L2 is reached, now torque-transfer capability reduces；Work as sensing
Body (17) rotating speed is gradually increasing, and speed discrepancy is less and less, and the magnetic induction force produced between permanent magnetic disk (9) and inductor (17) subtracts
Small, the magnetic force between permanent magnetic disk (9) and permanent magnetism backboard (4) strengthens gradually, so that between showing as permanent magnetic pulling between the two
Gap is tapered into.As gap reduces, the moment of torsion increase of transmission is gradually accelerated, most with loading the permanent magnet rotating speed being connected
After reach a normal speed speed of service.
The beneficial effects of the invention are as follows：
Inductor (17) makes full use of the magnetic line of force relative to (9) permanent magnetic disk (9) symmetric configuration, transmits the efficiency high of moment of torsion；
Using the change between permanent magnetic and induced magnetism with speed discrepancy, the purpose of soft start is realized, soft start high with transmission efficiency
The good advantage of effect.
