Definitions
- the invention relates to a side channel compressor according to the preamble of claim 1.
- Such a side channel compressor is known from DE-U-74 18 776.
- the cover part is attached to the impeller by riveting.
- it extends only over a partial area between the support ring and the hub part. This can easily deposit dirt in the uncovered area of the impeller.
- the invention has for its object to develop a side channel compressor of the generic type so that the cover is much easier to mount on the impeller.
- FIG. 1 shows a side channel compressor connected to a drive motor in section
- FIG. 2 shows a conical cover part in section.
- the side channel compressor 1 denotes a side-channel compressor connected to a drive motor 2, the housing of which consists of a first and a second housing half 3 and 4.
- the side channel compressor 1 also has an impeller 6.
- the impeller 6 has a support ring 7 on which the conveyor blades 8 of the impeller 6 are arranged. Via a wall part 9, the support ring 7 is connected to a hub part 10 which is plugged onto the end of the shaft 5 of the drive motor 2.
- the hub part 10 is rotatably coupled to the shaft 5.
- the wall thickness of the wall part 9 is thinner than the axial width of the impeller 6.
- the wall part 10 is arranged on one side of the impeller 6 so that it forms the one boundary wall of the impeller 6. This lateral arrangement of the wall part 9 results in a niche-shaped recess 11 in the impeller 6.
- a relatively long, narrow gap 13 is therefore formed between the one boundary wall of the impeller 6 formed by the wall part 9 and the wall 12 of the first housing half 3 running parallel thereto.
- a cover part 14 made of sheet metal or plastic extends from the support ring 7 to the hub part 10.
- the cover part 14 is designed as a round disk and has a shaft opening 15 so that it can be plugged onto the end of the shaft 5. With its peripheral edge 16, the cover part 14 rests in a corner recess 17 formed on the support ring 7.
- a screw 18 screwed into the end of the shaft 5 which acts via an intermediate washer 19 on a clamping ring 20 loosely fitted onto the shaft end, the cover part 14, which is plugged onto the shaft end, is pressed in the region of its shaft opening 15 against a stop surface 21 of the hub part 10 pressed.
- the axial bracing of the cover part 14 which is necessary for holding the cover part 14 on the impeller 6 can be achieved in that the cover part 14, as shown in FIG. 2, is conical. This results in a force acting in the axial direction when the screw 18 is tightened, which presses the cover part 14 with its peripheral edge 16 into the corner recess 17 of the support ring 7.
- the axial pressing of the cover part 14 into the recess 17 can be achieved with a completely flat design of the cover part 14 in that the stop surface 21 formed on the hub part 10 in its plane relative to the plane of the axial stop surface of the corner recess 17 of the support ring 7 is reset, as is indicated by dashed lines in FIG. 1 on the hub part 10. Even with such a configuration, when the screw 18 is tightened, an axial pressing force is generated which holds the cover part 14 in the corner recess 17 in contact with the corresponding stop surface of the corner recess 17.
- the cover part 14 fastened to the impeller 6 forms the other boundary wall of the impeller 6.
- a long, narrow gap 23 is thus also formed between this other boundary wall and the corresponding wall 22 of the second housing half 4 which runs almost parallel to this.
- the gaps 13 and 23 thus existing on both sides of the impeller are distinguished by a large sealing effect.
