Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Other advantageous further developed embodiments of the disclosure are characterized in the dependent claims and/or are described in more detail through the drawings in conjunction with the description of the preferred embodiment of the disclosure. The drawings show:

(2) FIG. 1 An axial top view of a gas blower with a blower housing component attached to it;

(3) FIG. 2 A perspective view of the blower housing component from FIG. 1; and

(4) FIG. 3 A side view of the blower housing component from FIG. 2.

DETAILED DESCRIPTION

(5) In FIG. 1, a gas blower 100 with an attached blower housing component 1 is designed as a diffuser housing with a suction opening 14 for ambient air and a fuel gas connection 9.

(6) The blower housing component 1 shown in FIGS. 1-3 comprises the essentially cylindrical housing body 2 which is arranged on a mounting flange 3 on an axial end side, wherein the mounting flange 3 extends radially outward beyond the housing body 2. The mounting flange 3 is the component with which the blower housing component 1 is fastened to the gas blower 100 by means of bolts 7 via the mounting points 4 formed as bolt-receiving points. Three groups of two mounting points 4 each are provided at the mounting flange 3, distributed in the circumferential direction, the groups of mounting points 4 being spaced apart at an angle of 120° in the circumferential direction. Immediately adjacent mounting points 4 within a group are again spaced at an angle of 30°, such that two mounting positions rotated to each other by 30° of the blower housing component 1 at the gas blower 100 result and are feasible.

(7) A radial rib 5 extends radially outward from the lateral surface 8 of the housing body 2 to each of the mounting points 4. In addition, radial ribs 5 are also provided in intermediate areas, which end at the radial, free surrounding edge of the mounting flange 3. Furthermore, the tangential ribs 6 extend, and intersect the radial ribs 5, between respectively adjacent mounting points 4 of the two groups each having three mounting points 4. As clearly shown in FIG. 2, the radial ribs 5 and the tangential ribs 6 alternately penetrate each other, and end at the respective material reinforcement 24 of the mounting points 4. FIG. 2 also clearly shows that the tangential ribs 6 also intersect. The resulting transverse ribbing provides a high stiffness in the radial direction and tangential direction.

(8) The tangential ribs 6 are radially spaced apart from the housing body 3 and extend tangentially toward the housing body 3 from the respective mounting point 4.

(9) Referring to FIG. 3, the advantageous geometric details are specified in more detail, according to which the axial height of the radial ribs 5 continuously decreases from the lateral surface 8 radially outward to the mounting points 4. The tangential ribs 6 have an axial height h, which is proportional to a direct distance b between two mounting points 4 of a group, such that h/b=0.28. Alternatively, the ratio is set in a range of 0.2-0.4. The contour of the tangential ribs 6 between two fastening points 4, as seen from the side, is that of an arc that first ascends and then descends with regards to its axial height. At the vertex S, there is a radius R, which is in proportion to the direct distance b between two mounting points 4 of a group, such that R/b=0.2. Alternatively, the ratio is set in a range of 0.1-0.3.
