Description

Spindelmuttern, die aus einem - metallischen Grundkörper mit einem eingesetzten Kunststoffgewinde bestehen, sind bekannt. Auch die Spindelmutter, die Gegenstand der Erfindung ist, besteht aus einem metallischen Grundkörper und einem eingesetzten Kunststoffgewinde. Um die Preßstoffauskleidung fest in der Mutter zu verankern, ist das Kunststoffgewinde am Außenumfang trapezförmig ausgebildet. Zur Bewegungsübertragung ist das Kunststoffgewinde innen bogenförmig gestaltet.Spindle nuts consisting of a - metallic base body with a The plastic threads used are known. Also the spindle nut that The subject matter of the invention consists of a metallic base body and a inserted plastic thread. To hold the pressed lining firmly in the nut anchor, the plastic thread is trapezoidal on the outer circumference. To the The plastic thread is curved on the inside to transmit movement.

Eine beispielsweise Ausführungsform einer erfindungsgemäßen Spindelmutter ist in der Abb. i im Achsenschnitt und in der Abb.2 in Stirnansicht in der Zeichnung dargestellt.An example embodiment of a spindle nut according to the invention is in Fig. i in axial section and in Fig.2 in front view in the drawing shown.

Bei dem dargestellten Ausführungsbeispiel ist ein Kunststoffkörper a in eine Stahlmutter b eingelassen und bildet das eigentliche Muttergewinde. Die Stahlmutter ist mit Trapezgewinde versehen, so daß der Kunststoffkörper a mit seinen entsprechenden Gewindegängen tief an den Kern der Gewindespindel herangeführt werden kann und dadurch ein Abscheren auch bei stärkster Zugbeanspruchung vermieden wird. Dieses Spezialgewinde in dem Metallkörper b gewährleistet gleichzeitig eine gute Verankerung des Preßs.toffs. An der Innenseite ist der Gewindekörper a als Rund-oder Kordelgewinde ausgebildet, wodurch die Berührungsfläche zwischen dem Kunststoffkörper a, der Mutter und der Spindel nach Möglichkeit vergrößert wird. An den Stirnflächen ist der Gewindekörper a durch Metallplatten c abgedeckt, die dem Kunststoffkörper a einen sauberen Abschluß geben und die Kunststoffschicht auch bei stärkster Beanspruchung vor dem Ausplatzen schützen. In den Metallplatten c sind, wie die Draufsicht zeigt, Aussparungen d angeordnet, durch die der Kunststoff in die Spindelmutter eingepreßt wird. Am Umfang des Metallkörpers b und an seinen Stirnseiten sind Üffnungen e ibzw. f zuan Einbringen des Kunststoffs angeordnet. Versuche haben ergeben, daß die Spindelmutter mit Kunststoffgewinde gemäß der Erfindung gegenüber den bekannten Werkstoffkombinationen eine mehrfache Belastung aushält.In the illustrated embodiment, a plastic body a is embedded in a steel nut b and forms the actual nut thread. The steel nut is provided with a trapezoidal thread, so that the plastic body a with its corresponding thread turns can be brought up to the core of the threaded spindle, thereby avoiding shearing off even under the greatest tensile stress. This special thread in the metal body b also ensures good anchoring of the Preßs.toffs. On the inside, the threaded body a is designed as a round or cord thread, whereby the contact surface between the plastic body a, the nut and the spindle is enlarged as far as possible. At the end faces, the threaded body a is covered by metal plates c, which give the plastic body a a clean finish and protect the plastic layer from bursting even under the heaviest loads. In the metal plates c, as the plan view shows, recesses d are arranged through which the plastic is pressed into the spindle nut. On the circumference of the metal body b and on its end faces are openings e ibzw. f arranged for the introduction of the plastic. Tests have shown that the spindle nut with plastic thread according to the invention can withstand multiple loads compared to the known material combinations.
