Axis device active part, is reinstalled on rotating machinery M3, and reassemble, so that it may complete rotating machinery M3 substitution rotating machinery M2.
The magnetic pole arrangement that Fig. 5 expresses the structure of permanent magnet clutch 50 and simplifies.Permanent magnet clutch 50 is by permanent magnet clutch active
End, permanent magnet clutch driven end composition, there are the radial clearances of complete cycle between powered phase and driven end.Plum blossom yielding coupling is logical
It crosses elastomer and transmits torque between plum blossom yielding coupling active end flanges and the driven end flanges of plum blossom yielding coupling, it is each to connect
There are material contacts between part.Permanent magnet clutch transmits torque by invisible magnetic force between active part and secondary part.It is main
There is no material contacts between dynamic part and secondary part.Since there are N grades and S grades of phase between active part and secondary part
Mutually attract, N grade and N grade and S grade are mutually exclusive with S grades, therefore when active part rotates, secondary part follows rotation, master
Secondary part follows movement when dynamic part moves axially, and when active part axial movement, secondary part can keep axial static
Only and circle rotation.
Fig. 6-Figure 13 expresses the dynamic process of rotating machinery M3 replacement rotating machinery M2, and rotating machinery M1 remains company
Continuous rotation.
Fig. 6, orientation barrel bolt 42 of dismantling.
Fig. 7 moves axially rotating machinery M2, and driven end, which is connected in pinion gear, keeps axial static circle rotation.Remaining
Part follows rotating machinery M2 while moving axially.
Fig. 8 continues to move axially rotating machinery M2, and driven end is just axially offset with powered phase, but orientation barrel is still sent out
Wave guiding role.
Fig. 9 continues to move axially rotating machinery M2, and secondary part is completely separated with active part.
Figure 10, right seam allowance connection bolt of dismantling；
Figure 11, rotating machinery M2 are separated with active part and intermediate sleeve；
Figure 12, replaces rotating machinery M3, and rotating machinery M3 is connect with active part and intermediate sleeve；
Figure 13, rotating machinery M3 move axially to the position of rotating machinery M2 by orientation barrel, substitute rotating machinery M2.
