Description
Die Erfindung betrifft eine Befestigungsvorrichtung einer Befestigungsstrebe für ein Lüfterschutzgitter sowie ein Lüfterschutzgitter mit wenigstens einer Befestigungsstrebe und einer derartigen Befestigungsvorrichtung.The invention relates to a fastening device of a fastening strut for a fan protection grille and a fan protection grille with at least one fastening strut and such a fastening device.
Lüfterschutzgitter werden beispielsweise bei Axiallüftern als Berührschutz eingesetzt. Sie umfassen üblicherweise eine Vielzahl von konzentrischen in radialer Richtung beabstandeten Gitterstäben. Zudem sind die Lüfterschutzgitter häufig dreidimensional ausgebildet, wobei ihr radialer Randabschnitt durch hauptsächlich axial beabstandete Gitterstäbe gebildet ist. Auch zueinander radial und axial beabstandete Gitterstäbe können vorgesehen sein, um schräge Verläufe auszubilden.Fan protection grilles are used, for example, in axial fans as protection against contact. They usually include a large number of concentric bars spaced apart in the radial direction. In addition, the fan guards are often designed three-dimensionally, with their radial edge section being formed by mainly axially spaced grid bars. Grid bars spaced radially and axially from one another can also be provided in order to form oblique courses.
Durch radial über die Gitterstäbe verlaufende Befestigungsstreben werden die Gitterstäbe der Lüfterschutzgitter miteinander positionsfest befestigt und stabilisiert. Zudem werden die Lüfterschutzgitter über die Enden der Befestigungsstreben an dem Lüfter bzw. dem Lüftermotor befestigt. Diese Anbindungsstellen sind hohen Belastungen ausgesetzt, da zum einen die durch den Betrieb des Lüftermotors erzeugten Biege- und Rotationsmomente, zum anderen im Betrieb erzeugte Schwingungen aufgenommen werden müssen. Die Anbindungsstelle der Befestigungsstrebe muss deshalb äußerst stabil ausgebildet sein, um Brüche der Strebe oder der Befestigungsmittel zu verhindern. Entsprechende Anforderungen werden generell auch an die Befestigungslösung der Streben gestellt.The grille bars of the fan guards are fastened and stabilized in a fixed position with one another by fastening struts that run radially over the grille bars. In addition, the fan protection grilles are attached to the fan or the fan motor via the ends of the fastening struts. These connection points are exposed to high loads because, on the one hand, the bending and rotational moments generated by the operation of the fan motor and, on the other hand, vibrations generated during operation must be absorbed. The connection point The fastening strut must therefore be extremely stable in order to prevent breakage of the strut or the fastening means. Corresponding requirements are generally also placed on the fastening solution for the struts.
