Description
Technical field
This utility model relates to a kind of bonder, particularly a kind of adjustable speed umbrella-type magnetic coupling.
Background technology
The operation principle of magnetic coupling follows the Coulomb's law of magnetic, i.e. two magnets separated by a distance, by
In magnetic field induction effect, they need not any traditional mechanical means, by the bonding force of magnet, and just can be merit
Rate is delivered to another one magnet from a magnet, constitutes the mechanism of a noncontact transmission torque.
Permanent magnetic vortex drive device is mainly made up of conductor rotor, p-m rotor and three parts of controller, and copper turns
There is the air gap (referred to as air gap) between son and p-m rotor, do not transmit the mechanical connection of moment of torsion.So,
Define soft (magnetic) between motor and working machine to connect, realize working crankshaft moment of torsion by regulation air gap, turn
The change of speed.
Above-mentioned magnetic coupling also exists following defect: 1) when after magnetic coupling long-term work, rotor due to
A variety of causes can be damaged, and during existing magnetic coupling more exchanging rotor, need to be moved by pedestal, thus needs weight
New centering, substantially prolongs the repair time of equipment；2) existing disc type magnetic coupler because of shared by it radially
Space is relatively big, limits its application on a few thing space-constrained occasion (such as automotive interior)；3)
In work process, axial force produced by conductor rotor and magnet rotor can produce impact to the work of motor；4)
In work process, existing magnetic coupling can make conductor rotor produce relative with magnet rotor due to factors such as vibrations
Axial jump, thus change size of gaps, cause the instability that equipment runs.
Utility model content
This utility model overcomes deficiency of the prior art, it is provided that one can make coupler performance, service life
Greatly improving, application occasion is more extensive, overhauls convenient and simple magnetic coupling.
The technical scheme is that this utility model of this utility model include actuator, regulating sleeve,
Linking arm, conductor rotor, umbrella-type p-m rotor assembly, umbrella-type p-m rotor assembly is by even-even permanent magnet and forever
Magnet matrix and a rotating disk composition.Permanent magnet matrix is connected with rotating disk by hinged；Described permanent magnet matrix
It is hinged with linking arm respectively with adjustable sleeve；Output shaft the inner is provided with and connects diagonally with power shaft
Contact ball bearing；Adjustable sleeve is connected with actuator by bidirectional angular contact thrust ball bearing；Umbrella-type permanent magnetism
Permanent magnet matrix in rotor assembly can be rotated relative to rotating disk by hinged, thus changes permanent magnet and conductor
Between size of gaps.
Permanent magnet outer surface of the present utility model is cambered outwards arc surface；The angular contact ball bearing that output shaft is inner
Inner ring and power shaft interference fit, outer ring is positioned by the shaft shoulder and snap ring；Regulating sleeve by actuator drive into
Row moves axially.
The utility model has the advantages that: 1) conductor rotor of the present utility model and PM rotor use umbrella structure,
Relative to traditional disc type magnetic coupler, save its radially work space, increased bonder working environment
Range of application；2) this utility model and traditional disc type magnetic coupler are under identical radial dimension, by
In using umbrella-type structure, work area is relatively big, can transmit bigger operation torque；3) this utility model uses
Umbrella-type structure make between conductor rotor and PM rotor produced axial force make a concerted effort the least, axial force
Born by angular contact ball bearing, reduce the work load of power shaft, output shaft, improve its service life；
4) output shaft the inner of the present utility model be provided with and power shaft connect diagonally contact ball bearing, can reduce by
The impact that the equipment fluctuation of service making air gap change in factors such as vibrations and to cause is brought；5) this practicality is new
Type simple in construction, convenient disassembly during maintenance, decrease downtime, improve service efficiency.

9 are arranged on output shaft 12, and output shaft 12 the inner is provided with the angular contact ball bearing 10 connected with power shaft 1,
Angular contact ball bearing 10 inner ring and power shaft 1 interference fit, outer ring is positioned by the shaft shoulder and snap ring 11.
Permanent magnet 8 by N level, S level even number is alternate is tightly fixed on permanent magnet matrix 6, permanent magnet matrix 6
It is hinged with linking arm 5 respectively with adjustable sleeve 4.
The material of permanent magnet 8 is based on the rubidium ferrum boron in high performance rare earth alloy, the material of permanent magnet matrix 6
With aluminum, copper, the non-magnetizable material such as austenitic stainless steel is main, conductor rotor 9 with the metallic aluminium of non-magnetizable material,
Copper is main.
On described adjustable sleeve 4, bidirectional angular contact thrust ball bearing 3 is installed, by abutment sleeve 14 He
Screw 13 positions.Bidirectional angular contact thrust ball bearing 3 is connected with actuator 2, passes through actuator
2 drive moving axially of adjustable sleeve 4, make permanent magnet matrix 6 rotate relative to rotating disk 7, so that
Size of gaps between permanent magnet and conductor rotor produces change.
