Description
Technical field
The present invention relates to a kind of drive unit, relate to specifically a kind of dish type rotating disk permanent magnetic coupling that adopts permanent-magnet eddy current principle of induction.
Background technology
Existing electric system, substantially all there is the phenomenon of low load with strong power, waste of energy is serious, and traditional machenical coupling is inevitably delivered to the other end by shaft coupling from one end vibration, obviously do not possess separating vibration and energy-conservation performance, in " energy-saving and emission-reduction " 12 " planning ", clearly propose to use the energy-conservation technical optimization system operation and controls such as permanent-magnet eddy current Flexible Transmission, improve entire system operational efficiency.
In this case, permanent magnetic coupling is a novel ideal chose in electrical machine energy-saving field.
Summary of the invention
The present invention aims to provide the large dish type rotating disk of a kind of moment of torsion permanent magnetic coupling.
For achieving the above object, the present invention has adopted following technical scheme:
Dish type rotating disk permanent magnetic coupling of the present invention, comprise split and coaxial the first axle and the second axle, the first axle is provided with axle sleeve and permanent magnetic rotation disc, one circle permanent magnet is installed on permanent magnetic rotation disc, permanent magnet magnetic extreme direction is consistent with rotating disk axis, adjacent magnets magnetic pole heteropole is installed, and adopts little matched in clearance to add expansion connecting sleeve mode and connect fastening or connect with key between axle sleeve and the first axle;
The second axle is provided with axle sleeve, axle sleeve one end is socketed in outside the second axle, the axle sleeve other end is connected with conductor rotating disk, outrigger shaft and the second axle coaxially arrange, and outrigger shaft is through conductor rotating disk, and its one end is connected with axle sleeve, the other end is connected with adjustment disk, adjustment disk is that cross section is trapezoidal disk, between conductor block, is connected and is arranged on adjustment disk periphery with spring, and conductor block has the inclined-plane coordinating with adjustment disk periphery.
That described permanent magnet shape can be is fan-shaped, rectangle, ellipse or circular; On described permanent magnetic rotation disc, have a circle installing hole, permanent magnet is located in installing hole.
Between described axle and axle sleeve, being provided with expansion sleeve or key connects.
Described conductor rotating disk has groove, and conductor block is arranged in groove.
Compared with prior art, the invention has the beneficial effects as follows:
Magnet on permanent magnetic rotation disc divides extremely adjacent arranging of N, S, the magnetic line of force is through corresponding conductor block 7, in the time of relative motion between the two, conductor block cutting magnetic line, in conductor block, produce vortex flow, vortex flow and then generation dislike magnetic field, stop relative motion between the two, thereby realize moment of torsion transmission between the two.The magnetic field intensity of passing is between the two larger, and the moment of torsion of transmission is larger; Relative motion is faster, and the moment of torsion of transmission is larger.
In the contactless transmission that realizes power, avoid axial thrust, increase coupling area, in the time of starting, can realize the complete starting under no load of motor, realized the non contact transmission of torque, thereby mechanical friction and wearing and tearing are reduced, avoid the interference of vibration, reduced the loss of drive disk assembly, isolated vibration and also reduced noise, Installation and Debugging are simultaneously fairly simple, allow certain axial endplay.
