Definitions
- the invention relates to a compressor unit according to the preamble of claim 1.
- Such a compressor unit is known from DE-U-92 15 231, EP-A-0 351 372 and FR-A-2 294 114 known.
- the compressor unit known from DE-U-9 215 231 is radially outside a centering edge of the housing area forming the side channel provided on the individual housing halves.
- the side channel blowers are aggregated by the respective internal housing halves, which with their centering edges interlock, centered to each other.
- the connection the one belonging to a side channel blower Housing halves are made on the outer circumference of these housing halves provided connecting tabs, in the connecting screws are introduced.
- the connecting straps are adjacent the inner parting plane of the two housing halves.
- the invention has for its object a compressor unit of the generic type so that both Side channel blowers with the same housing diameters as also with different housing diameters Compressor unit can be summarized.
- the task is solved by the im Characteristics of claim 1 specified features.
- the side channel blowers belonging to an aggregate are theirs
- the basic structure of the housing halves is identical.
- the one necessary for one outer half of the housing Stock taking can be made using an appropriate, interchangeable Mold insert can be achieved in the mold.
- a technically identical design of all halves of the housing side channel compressors that can be joined together to form a compressor unit is made possible by the fact that in all housing halves the axial approach on the same radius as that for the Coupling the respective outer housing half to the Housing of the drive motor of the compressor unit necessary Axial approach lies.
- each side channel blower 1 or 2 consists of an outer housing half 3 and an inner housing half 4.
- the housing halves 3 and 4 enclose the impeller 5 in the assembled state of the side channel compressor 1 or 2.
- each housing half 3 or 4 there is between one the axial shaft hub surrounding the drive shaft 6 of the impellers 5 7 and the one forming the respective side channel 8 Bulge 9 extending housing wall 10 an axial shoulder 11th molded.
- the axial lugs 11 of the two inner housing halves 4 serve to connect these two housing halves 4. Therefore, the axial shoulder 11 of the one housing half 4 Through holes 12 and the axial approach 11 of the other Provide housing half 4 with threaded holes 13. Consequently can the two inner housing halves 3 by means of screws 14 are connected.
- the axial approach 11 can be as circumferential ring can be formed or from individual There are protrusions.
- Axial extension 11 is used to attach the compressor unit on the housing of the drive motor 15.
- Threaded holes 13 are provided so that the outer housing half 3 of the first side channel compressor 1 by means of connecting screws 16 can be attached to the motor housing.
- the connection of the outer housing half 3 of the second Side channel compressor 2 takes place in on the outer circumference of all Housing halves 3 and 4 provided through openings 19 inserted clamping bolts 18.
- the clamping bolts 18 extend axially over all housing halves 3 and 4 and thus pose an additional fastening element for all housing halves 3 and 4.
- a support ring 20 is provided radially adjacent. For reasons of equality is this support ring 20 on each housing half 3 or 4 molded.
- the support rings 20 are regarding their axial extension so dimensioned that the two inner housing halves 4 provided support rings 20 in connected state of the inner housing halves 2 to each other issue. So there is no warping of the case of the two Side channel compressors 1 and 2 when attaching the clamping bolts 18 possible.
- the axial approaches are in all housing halves 3 and 4 regardless of whether they are used Connection of the housing halves 4 to each other or to Connect the compressor unit to the drive motor 15 serve on the same radius. This is the same training all housing halves 3 and 4 from their casting Execution given here.
- the bearing holder 17 in one outer housing half 3 can by a corresponding, in the mold insertable, replaceable mold insert reached become.

Description
Claims (4)
- Verdichteraggregat, das aus mindestens zwei axial nebeneinander angeordneten Seitenkanalverdichtern (1 und 2) besteht, die jeweils ein mindestens aus einer inneren (4) und einer äußeren (3) Gehäusehälften bestehendes Gehäuse aufweisen, die durch an ihrem Außenumfang in Durchstecköffnungen (19) einbringbare Verbindungselemente (18) miteinander verbindbar sind und die äußeren Gehäusehälften (3) durch die in die Durchstecköffnungen (19) eingebrachten Verbindungselemente (18) mit den inneren Gehäusehälften (4) verbunden sind,
dadurch gekennzeichnet,
daß sowohl an der inneren als auch an der äußeren Gehäusehälfte (3, 4) an der sich zwischen einem axial erstreckenden Nabenansatz (7) und der durch den Seitenkanal (8) bedingten Gehäuseausbuchtung (9) erstreckenden Gehäusewand (10) ein Axialansatz (11) vorgesehen ist, daß der Axialansatz (11) zumindest bei den beiden einander zugewandten Gehäusehälften (4) der miteinander zu verbindenden Seitenkanalverdichter (1 und 2) auf gleichem Radius liegt und sich jeweils bis in die Trennebene der aneinderzufügenden Gehäusehälften (3 bzw. 4) erstreckt und jeweils mit einem über die Trennebene vorstehenden Zentrierrand (21) versehen ist, der mit einem am Axialansatz (11) der benachbarten Gehäusehälfte (4) vorgesehenen, gegenüber der Trennebene zurückspringenden Zentrierabsatz (22) zusammenpaßt, und daß die inneren Gehäusehälften (4) an den Axialansätzen (11) miteinander verbunden sind. - Verdichteraggregat nach Anspruch 1,
dadurch gekennzeichnet,
daß zu den Verbindungselementen (18) radial benachbart zumindest an den inneren Gehäusehälften (4) bis in die Gehäusetrennebene ragende , axial gerichtete Abstützelemente (20) vorgesehen sind. - Verdichteraggregat nach Anspruch 2,
dadurch gekennzeichnet,
daß die Abstützelemente als umlaufender Abstützring (20) ausgebildet sind. - Verdichteraggregat nach einem der vorhergehenden Ansprüche,
dadurch gekennzeichnet,
