The circumferential direction between ring structure of different axial dimensions should be provided multiplied by feasible in the quantity in the hole in other ring structures
The quantity of relative position.If therefore for example constructing the hole that quantity is N at ring structure, other ring structures must possess
X*N hole, wherein x is the quantity of the feasible relative position between ring structure 20,21 for providing different axial dimensions.
The other variant schemes of the embodiment of Fig. 2 and 3 is that the first ring structure is in the axial face towards the second ring structure
On there is the protrusion wedge-shaped in other words of ramped shaped being spaced each other in the circumferential, and the second ring structure is towards the first ring knot
There is the protrusion wedge-shaped in other words for the same ramped shaped being spaced each other in the circumferential in the axial face of structure.When such ramped shaped
Or wedge-shaped the first ring structure protrusion rest on the second ring structure ramped shaped or when in wedge-shaped protrusion, then can be through
The circumferential relative position between the ring structure being defined is crossed to set axial dimension and thus infinitely in minimum dimension
The axial gap 19 being set between full-size between shell 11 and active wheel 12.
In this case then it is possible that the hole of identical quantity is arranged on two ring structures, i.e., on ring structure
Be spaced each other in circumferential direction for accommodate bolt 17 threaded hole and be configured at other ring structures long hole without screw thread
The hole moved towards deviously in the circumferential.
In the preferred embodiment of radial compression device 10 out shown in Fig. 1, ring structure 21 is preferably installation part 14
Flange section 16 integration component part.Ring structure 20 and then the preferably integration of the flange section 15 of propeller cap 13
Component part.By installation part 14 and thus relative to propeller cap 13 and thus its ring structure of its ring structure is in the circumferential
Torsion, the axial position relative to active wheel 12 of installation part 14 can be set, so as to be set in shell 11 and active wheel
Axial gap 19 between 12.This relative position be connected bolt 17 (the connection bolt for connect two shell sections 13,
14) insure, wherein in a ring structure mesoporous without threadably implementing, and the hole described in other ring structures is implemented
For threaded hole.
If in the assembly of fluid machine, for ring structure 20,21 correct relative position in the circumferential by with
In setting axial slits 19, then preferably at one of ring structure place, for the setting for desired axial gap just
At least one of described hole being not needed when the connection of the ring structure in true circumferential relative position is closed, so as to for example
Furthermore by that can be assemblied in correct circumferential relative position when the dismounting of its ring structure caused by service scenario.
