Embodiment Construction

[0020] exist Figure 1-4 An exemplary embodiment of a fastening arrangement for two housing parts is shown in FIG. 2 , which are designed as fan housing parts 2 , 3 in the form of a protective grid and fan ring housing. Formed in one piece on the housing part 3 in the circumferential direction are three geometrically identical receptacles 6 each spaced apart by 120°, each receptacle having two guide webs 9 . The guide webs 9 extend V-shaped towards each other and delimit wedge-shaped receiving spaces 5 between them.

[0021] The housing part 2 , which is designed as a protective grid, comprises five coaxial circulating struts 8 and nine radial struts 7 in the illustrated embodiment and is designed axially and radially open. The number of circulation struts 8 and radial struts 7 can be matched as required. Extending integrally from the housing part 2 are three locking hooks 4 each having a wedge shape corresponding to the receiving space 5 . On the outside, on each locking h...
