In the shaft connectors in magnetic coupling, a copper rotor is fixed at the power rotary shaft end through a bolt, a permanent magnet rotor is fixed at a load rotary shaft end through a bolt, and the copper rotor corresponds to the permanent magnet rotor and has a gap with the permanent magnet rotor. The shaft connectors are used for flexible connection through the magnetic field force, between a power rotary shaft and a load rotary shaft which are indirectly connected, overcome the defect of traditional rigid connection, are convenient to realize regulation of load rotational speed and torque, avoids vibration transfer and noise superposition and ensures stable running of a system.
Description
Technical field
The utility model relates to a kind of mandrel connector of magnetic couplings.
Background technology
In plant equipment, the connection of all kinds of rotating shafts realizes being connected as adopting connecting axle or shaft coupling between machine shaft and load rotating shaft usually.This class connection generally all is rigidly connected, and it directly passes to load with the kinetic energy of power end.Be rigidly connected the centering of equipment room is had relatively high expectations, the vibrations of power end and load end are transmitted mutually, the noise stack, and system start-up moment is big, no overload protection.And rigidly connected installation, dismounting, debugging, maintenance are all comparatively complicated, the maintenance cost height.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of mandrel connector of magnetic couplings, this mandrel connector is used for flexibly connecting between power and load rotating shaft, it has overcome the defective that conventional rigid connects, the convenient adjustment that realizes load speed, moment of torsion, avoid shock transfer, noise stack, guarantee system's even running.
For solving the problems of the technologies described above, the mandrel connector of the utility model magnetic couplings comprises copper rotor and p-m rotor, described copper rotor by bolt in the power shaft end, in load rotating shaft end, described copper rotor is corresponding with p-m rotor and have a certain clearance by bolt for described p-m rotor.
For reaching desirable magnetic couplings effect, above-mentioned p-m rotor comprises aluminum rotor and ferro-boron neodymium permanent magnet, in described aluminum rotor surface, described aluminum rotor is connected by bolt with the load rotating shaft described ferro-boron neodymium permanent magnet along described aluminum rotor circumference uniform distribution.
Above-mentioned copper rotor comprises a copper coin dish and steel rotor, and described copper coin dish is connected with power shaft by bolt, and described steel rotor is connected with described copper coin dish outer ring by bolt.
Because the mandrel connector of the utility model magnetic couplings has adopted technique scheme, be about to copper rotor by bolt in the power shaft end, in load rotating shaft end, copper rotor is corresponding with p-m rotor and have a gap by bolt for p-m rotor; The magnetic field force that this mandrel connector is used between power and load rotating shaft flexibly connects, and it has overcome the defective that conventional rigid connects, and shock transfer, noise stack are avoided in the convenient adjustment that realizes load speed, moment of torsion, guarantee system's even running.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the mandrel connector of the utility model magnetic couplings,
Fig. 2 is the structural representation of p-m rotor in this mandrel connector,
Fig. 3 is the end view of Fig. 2.
Embodiment
As shown in Figure 1, the mandrel connector of the utility model magnetic couplings comprises copper rotor 1 and p-m rotor 2, described copper rotor 1 is fixed in power shaft 3 ends by bolt 5, and described p-m rotor 2 is fixed in load rotating shaft 4 ends by bolt 6, and described copper rotor 1 and p-m rotor 2 are corresponding and have a gap.
As shown in Figures 2 and 3, for reaching desirable magnetic couplings effect, above-mentioned p-m rotor 2 comprises aluminum rotor 21 and ferro-boron neodymium permanent magnet 7, in described aluminum rotor 21 surfaces, described aluminum rotor 21 is connected by bolt with the load rotating shaft described ferro-boron neodymium permanent magnet 7 along described aluminum rotor 21 circumference uniform distributions.
Above-mentioned copper rotor 1 comprises a copper coin dish 11 and steel rotor 12, and described copper coin dish 11 is connected with power shaft 3 by bolt 5, and described steel rotor 12 is connected with described copper coin dish 11 outer rings by bolt 8.
This mandrel connector is to realize by the torque transfer of power shaft to the load rotating shaft no direct mechanical attachment between power shaft and load rotating shaft by the air gap between magnetic conductor and the permanent magnet.Its operation principle is to be interacted by an end rare metal oxide ferro-boron neodymium permanent magnet and other end induced field to produce torsional forces, load rotating shaft and power shaft are rotated synchronously, just can controlling magnetic field power come the transfer torque size by the air gap of regulating between permanent magnet and the magnetic conductor, thereby realize the process of loading speed, torque adjustment.
Do not do the time spent when there being external force, the mutual adhesive of opposed polarity that the copper rotor of magnetic conductor is relative with the p-m rotor both sides, if when power shaft produces rotation under external force, the load rotating shaft is then owing to the effect both sides magnetic pole of inertia and load misplaces, the magnetic pole of both sides also has the mutual repulsive force effect of homopolarity except the power that attracts each other of heteropole at this moment.Attraction and repulsive force have formed " push-and-pull " active force, thereby drive load rotating shaft rotation, realize magnetic drives.Power shaft and load rotating shaft are changed into the connection of magnetic field force by original mechanical attachment like this.Just can realize that by the gap of adjusting between p-m rotor and the copper rotor output torque in the load rotating shaft changes, thereby realize that load speed changes.The moment of torsion of its output can be according to following formula:
M＝9550*P/N
M wherein---output torque (newton. rice)
P---transmission power (kilowatt)
N---rotating speed (rev/min)
Adopt this mandrel connector, power shaft only produces the needed moment of torsion of load rotating shaft, the ability of transmission of power and control rate is not subjected between power shaft and the load rotating shaft because not former thereby the low-angle of generation or the influence of little skew of centering is installed, the vibration problem of having got rid of centering not and having produced, owing to there is not the rigid attachment of machinery, even the vibration of power shaft itself also can not cause the vibration of load rotating shaft, make the operation of whole system more stable, noise-decreasing.
