Together, realize the non-contact magnetic coupling of the power rotor 14 and the driven rotor 13, thus complete the vertical machine with
The connection of the load end.
Since stop sleeve 20 uses split structure, i.e., connected and formed by the first sleeve 21 and second sleeve 22, pacified
During dress, first, the first axle sleeve 11,14 and first sleeve 21 of power rotor are installed on vertical machine 30, the second axle sleeve 12, driven
Rotor 13 and second sleeve 22 are installed on load end 40, are then connected the first sleeve 21 and second sleeve 22 of partial installation
The problem of completing installation together, being inconvenient to twist bolt when avoiding integral sleeve installation, and the vertical mounting structure solution
Determine the vertical installation problem of permanent magnet clutch, easily connection and separation, and can realize faulty motor in multi-machine interaction system
ON-LINE SEPARATION maintenance and reset.
As shown in Figure 1, the connection between vertical machine 30, the first sleeve 21, second sleeve 22 and load end for convenience,
Alternatively, first sleeve 21 and 30 flanged joint of vertical machine, the second sleeve 22 and 40 method of load end
Orchid connection, first sleeve 21 and 22 flanged joint of second sleeve so that easy disassembling between any two, accurate positioning.
As shown in Figure 1, the connection of the first sleeve 21 and second sleeve 22 for convenience, alternatively, first sleeve 21
Outer circumferential surface on there is the first upper flange plate 21a and the first lower flange 21b, have the on the outer circumferential surface of the second sleeve 22
Two upper flange plate 22a and the second lower flange 22b.In the first sleeve installation steps, the first upper flange plate 21a with
The ring flange 32 of the vertical machine is located through bolt 23 and connects by end face and seam allowance so that the first sleeve 21 and vertical machine
30 connection lock out operation is easy, and both accurate positionings.In the second sleeve installation steps, second lower flange
Disk 22b is located through bolt 23 and is connected with the input terminal ring flange 42 of the load end by end face and seam allowance so that second sleeve
22 and load end 40 connection lock out operation it is easy, and both accurate positionings.The first lower flange 21b and described second
Upper flange plate 22a is connected by end face and excircle orientation by bolt 23 so that the first sleeve 21 and second sleeve 22 are easy to align with
Positioning, and easily the first sleeve 21 and second sleeve 22 can be linked together by bolt 23, both are connected firmly.
As shown in Figure 1 to Figure 3, in order to make the first sleeve 21 and second sleeve 22 be easy to be aligned, alternatively, the first set
First upper flange plate 21a of cylinder 21 is formed thereon end, and the first lower flange 21b of first sleeve 21 is formed under it
End, the second upper flange plate 22a portions formed therein of the second sleeve 22, the second lower flange of the second sleeve 22
22b is formed in its lower end, the second sleeve 22 include targeting part 22d above the second upper flange plate 22a and
Main part 22c below the second upper flange plate 22a, first sleeve 21 are set in the targeting part 22d
On.
In the sleeve connection step, the vertical machine 30 is lifted by crane, first sleeve 21 is directed at described
The targeting part 22d of two sleeves 22, then transfers the vertical machine 30 vertically, is set in first sleeve 21 described
On targeting part 22d, until the first lower flange 21b is fallen on the second upper flange plate 22a, realize that the active turns
The non-contact magnetic coupling of son 14 and the driven rotor 13, by the first lower flange 21b and the second upper flange plate 22a
Connected by bolt 23.
During sleeve connection, targeting part 22d plays guiding role to the first sleeve 21, prevent the first sleeve 21 with
Second sleeve 22 is not coaxial, avoids the power rotor 14 of shaft coupling and driven rotor 13 eccentric and be attached together.In addition, second
Upper flange plate 22a plays position-limiting action to the first sleeve 21, is installed in place it.
As shown in Fig. 2, in order to be preferably oriented to the first sleeve 21, alternatively, the inner circumferential of first sleeve 21
Face formed with internal keyway or internal spline 21c, on the outer circumferential surface of the targeting part 22d of the second sleeve 22 formed with it is described interior
Keyway or the matched outside keyways of internal spline 21c or external splines 22e.When mounted, the first sleeve 21 is formed with second sleeve 22
Spline fitted and be clearance fit, so that the first sleeve 21 can be more easily aligned with second sleeve 22, further prevents from joining
The power rotor 14 of axis device and driven rotor 13 are eccentric and be attached together, and ensure the coaxial of the first sleeve 21 and second sleeve 22
Degree.
As shown in Figure 1, in order to be further oriented to the first sleeve 21, alternatively, the axial direction of the targeting part 22d
Length is L0, and the axial length of the permanent magnet of the power rotor 14 or the permanent magnet of the driven rotor 13 is L1, L0 ＞ L1.
Therefore, when mounted, the first sleeve 21 is first contacted with targeting part 22d, and vertical machine 30 is axially further to moving down
After dynamic, power rotor 14 and driven rotor 13 just can be relative to each other, and attraction can be just produced between both magnets, avoids master
Turn 14 and driven rotor 13 are eccentric and be attached together, and cause between power rotor 14 and the magnet of driven rotor 13
Air gap is uniform.
In addition, in more motor linkage systems, when being overhauled to one of failure vertical machine, load end 40
Input shaft 41 continues to rotate, and due to the connection function of permanent magnet clutch, while drives 31 turns of the output shaft of vertical machine 30
It is dynamic, vertical machine 30 may be caused to rotate therewith.In this embodiment, due to being between the first sleeve 21 and second sleeve 22
Spline fitted, and L0 ＞ L1, i.e., after power rotor 14 and driven rotor 13 stagger completely vertically, the first sleeve 21 and
Two sleeves 22 are still within the state of part cooperation, limit the passive rotation of vertical machine 30.
As shown in Figure 1, in order to adjust the moment of torsion of permanent magnet clutch transmission, alternatively, the vertical mounting structure further includes
Adjust pad 24, the adjust pad 24 are arranged between the first lower flange 21b and the second upper flange plate 22a, with
The axial direction that the permanent magnet of permanent magnet and the driven rotor 13 for adjusting the power rotor 14 staggers relative to each other is long
Spend A.The thickness of adjust pad 24 is B, B=A, i.e. the thickness of adjust pad 24 is bigger, the permanent magnet of power rotor 14 and driven
The axial length A that the permanent magnet of rotor 13 staggers relative to each other is bigger, then the permanent magnet of power rotor 14 and driven rotor 13
Permanent magnet efficient coupling length it is smaller, then the moment of torsion of permanent magnet clutch transmission is smaller, and moment of torsion that is on the contrary then transmitting is bigger.
The second embodiment of the utility model as shown in Figure 4, the permanent magnet clutch 10 of the utility model can be disk
Formula synchronous permanent-magnet shaft coupling 50, wherein, power rotor 14 and driven rotor 13 are permanent magnetic disk；This practicality as shown in Figure 5 is new
3rd embodiment of type, the permanent magnet clutch 10 of the utility model can be disc type asynchronous permanent magnet shaft coupling 60, wherein, actively
Rotor 14 is conductor disc (such as copper dish), and driven rotor 13 is permanent magnetic disk.Second, third embodiment and first embodiment are not
It is that the structure of power rotor 14 and driven rotor 13 and form are different with point, the vertical peace of the permanent magnet clutch of the utility model
Assembling structure is also applied for disk synchronous permanent magnet clutch 50 and disc type asynchronous permanent magnet shaft coupling 60.Synchronous permanent-magnet shaft coupling 50 and disk
Formula asynchronous permanent magnet shaft coupling 60 includes the first axle sleeve 11, the second axle sleeve 12, driven rotor 13 and power rotor 14 respectively, and described
