BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a housing consisting of two housing halves for a side channel compressor.
Such a housing is known from DE-U-92 15 231. In that housing, the housing halves consist of metal, for example aluminum, and therefore have sufficient strength.
SUMMARY OF THE INVENTION
The object on which the invention is based is to design the housing of a side channel compressor in such a way that, when it is produced from a material, for example plastic, having lower strength than metal, it can withstand the loads which occur during operation.
This object is achieved, according to the invention, by forming in the front wall of each housing half at least two rings, spaced radially from one another and projecting axially relative to the front wall, and rib walls extending in a spoke-like manner between these rings. Such a housing, even when produced from plastic, has sufficient strength.
Since the radius of the rings corresponds approximately to the outer and the inner radius of the side channel formed in the housing halves, the rib walls come to rest on the outside of the wall part forming the side channel. Since it is precisely these wall parts which are subjected to the compression pressure, it is beneficial that these wall parts are supported correspondingly by the rib walls.
One of the rings can advantageously be designed as the centering ring.
A further increase in the strength of the housing can be achieved by forming in the front wall, in addition to the two rings, an axially extended centering ring located radially further inward, and by providing further rib walls extending in a spoke-like manner on the front wall between the centering ring and the ring adjacent to the centering ring.
Since the further rib walls are arranged in a manner staggered relative to the rib walls, the ring located between the further rib walls and the rib walls contributes to increasing the strength of the housing, since at least some of the load forces are conducted via this ring.
Furthermore, radially extended reinforcing ribs can additionally be formed on the front wall between the centering ring and a hub extension located radially further inward relative to the centering ring. With this arrangement, virtually the entire front wall of each housing half is appropriately reinforced.
Producing the housing halves from plastic affords the possibility, furthermore, of providing on each housing half, at the end circumferential edge lying in the parting plane of the housing halves, a sealing lip extending over one half of the circumference and a sealing groove extending over the other half of the circumference. By means of these sealing lips and sealing grooves which engage one in the other when the housing halves are assembled, a sufficient sealing of the parting gap between the two housing halves is achieved.
If the sealing lip and sealing groove extend in each case on one side and another in relation to a symmetrical dividing line of the housing halves, then an identical design of the two housing halves is possible.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a top view of a housing half of a side channel compressor housing, and
FIG. 2 shows the two housing halves of a side channel compressor housing in section along the line II--II in FIG. 1.
DETAILED DESCRIPTION OF THE DRAWINGS
The two housing halves of a side channel compressor housing are designated by reference numerals 1 and 2. A first and second ring 4 and 5 are formed on the front wall 3 of each housing half. The rings 4 and 5 project axially relative to the front wall 3 and are spaced radially from one another. The radius of the first ring 4 corresponds approximately to the outer radius of the side channel 6 formed in each housing half 1 and 2 and the radius of the second ring corresponds approximately to the inner radius of the side channel 6.
Between the first and second ring 4 and 5, rib walls 7 extending in a spoke-like manner are formed on the outside of the wall part 8 constituting the side channel 6. These rib walls
