Description

Gegenstand des Patents $153 082 ist eine Spindelmutter, bestehend aus einem metallischen Grundkörper mit einem eingesetzten Kunststoffgewinde, die dadurch gekennzeichnet ist, daß das Kunststoffgewinde am Innenumfang bogenförmig, am Außenumfang trapezförmig ausgebildet ist. In weiterer Ausbildung des. Gegenstandes .des Patents 853 082 sind erfindungsgemäß zur besseren Verankerung des Kunststoffes in den Gewindeflanken der Stahlmutter Kerben angeordnet und/oder die Ecken des trapezförmigen Gewindes abgerundet. Die Kerben können beispielsweise ebenfalls trapezförmig ausgebildet sein: In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt (Abb. i und 2). Es bedeuten a das Kunststoffgewinde, das im Innenumfang bogenförmig und am Außenumfang trapezförmig ausgebildet ist, b die Stahlmutter, g die abgerundeten Ecken des trapezförmigen Gewindes der Stahlmutter und h die Einkerbungen in den Gewindeflanken der Stahlmutter.The subject of patent $ 1 53 082 is a spindle nut, consisting of a metallic base body with an inserted plastic thread, which is characterized in that the plastic thread is arcuate on the inner circumference and trapezoidal on the outer circumference. In a further development of the subject matter of patent 853 082, according to the invention, for better anchoring of the plastic, notches are arranged in the thread flanks of the steel nut and / or the corners of the trapezoidal thread are rounded. The notches can, for example, also have a trapezoidal shape: the drawing shows an example of an embodiment of the invention (Figs. I and 2). It denotes a the plastic thread, which is curved on the inner circumference and trapezoidal on the outer circumference, b the steel nut, g the rounded corners of the trapezoidal thread of the steel nut and h the notches in the thread flanks of the steel nut.
