Description
Technical field
The present invention relates to technical field of power transmission, more particularly to a kind of magnetic coupling.
Background technology
Magnetic coupling is to realize that motor transmits to the torque of load by the air gap between conductor disc and permanent magnetic disk, by
High in its reliability, device structure is simple, the advantages such as fault rate is low, is widely used in mine and factory.It is higher in order to ensure
Efficiency of transmission, the air gap between the conductor disc and permanent magnetic disk should accomplish in theory it is smaller, actually due to processing and filling
The reason for technical elements, typically must also be ensured that certain air gap, to avoid producing mechanical friction in operation.For power
Larger coupler, such as it is used for the 400KW fans loads in mine, because the displacement in consideration at a high speed rotation, this air gap are general
Retain 5~8 millimeters.But in actual motion, the axial float from motor side be it is inevitable, especially after powering
Several seconds in the axle play of motor can reach maximum, and due to the speed discrepancy between startup stage conductor disc and permanent magnetic disk away from
Maximum, if mechanical friction occurs in both, permanent magnetic disk will be immediately resulted in and damage or reduce transmission performance because of frictional heating.
Device damage is more frequent caused by therefrom, and field maintenance is very inconvenient, and stopping production may be caused to result in greater loss,
And such big equipment beams back factory's maintenance, then more delay use.If for this by the gas between conductor disc and permanent magnetic disk
Gap setting is too big, although can avoid rubbing, caused by energy transmission loss can be very big, and very worthless scheme.
The content of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, there is provided one kind can keep air gap between conductor disc and permanent magnetic disk permanent
Fixed magnetic coupling.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of magnetic coupling, including conductor rotor disk and
P-m rotor disk, the conductor rotor disk include the master end conductor disc and slave end conductor disc being bolted to connection, institute
P-m rotor disk is stated between two conductor discs, fixation is maintained between the p-m rotor disk and the conductor disc
Air gap, load flange is fixed with the p-m rotor disk, it is characterised in that load the cylindrical of flange is set with axle
Hold, the bearing includes inner ring and outer ring, the cylindrical interference fit of the inner ring of the bearing and the load flange, the bearing
Outer ring be connected by connector with the outside of the slave end conductor disc.
The operation principle of the present invention is such：Due to conductor rotor disk and p-m rotor disk being carried out using connector
It is fixedly connected, when axial float occurs in motor side, axial force can be passed on bearing axle, so or prevents motor shaft
Play, or bearing axle synchronization play is driven, but total energy ensures that air gap is constant between conductor disc and permanent magnetic disk.Due to conductor disc and
Permanent magnetic disk is little in normal operation medium velocity gap, only exists one tens turns of slippage, therefore bearing used will have for a long time
Service life.
The beneficial effects of the invention are as follows：One to be to maintain air gap between conductor disc and permanent magnetic disk constant, it is entirely avoided by
In load or axial movement of motor and caused by coupler failure, greatly improve the service life of coupler；Two be due to not
Consider it is above-mentioned alter axle factor, so as to so that air gap keeps optimal between conductor disc and permanent magnetic disk, improve efficiency of transmission.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, the cylindrical of load flange is provided with the shoulder for being used for installing bearing.
Beneficial effect using above-mentioned further scheme is to set shoulder to be easy to the installation of bearing to position.
Further, the bearing is radial thrust bearing.
Beneficial effect using above-mentioned further scheme is that the class bearing can effectively bear axial force.
Further, the connector include vertical connection while and during horizontal connection, the horizontal connection side is provided with screw
Groove, is additionally provided with bearing holder (housing, cover) between the bearing outer ring and the connector, the bearing holder (housing, cover) is fixedly set in the bearing outer ring
On, the bearing holder (housing, cover) is provided with multiple fixing holes.The connector and the slave end conductor disc screw connection.
Multiple pads are additionally provided between the connector and the slave end conductor disc.
Beneficial effect using above-mentioned further scheme is, using flight, in that context it may be convenient to the fixed air gap of regulation.May be used also
To adjust fixed range by pad according to different air gap requirements.
Further, the slave end conductor disc is provided with radial direction dovetail groove, the connector and the slave end conductor disc
Joint face be provided with the coattail board that is adapted with the dovetail groove, the coattail board is slidably inserted into the dovetail groove
In.
It is using the above-mentioned further beneficial effect of scheme, because an advantage of magnetic coupling is driving shaft and driven
Axle allows for several millimeters of coaxial error, therefore this connector is connected with radially sliding for slave end conductor disc, you can
Eliminating this not coaxial caused additional stress influences.
