Abstract
Description
In der herkömmlichen Mechanik sind Getriebe sowie Motorengetriebe nicht verschleißfrei ausgeführt wegen ihrer berührenden Kugellager und Zahnräder. Außerdem steigt der mechanische Widerstand und Verlust bei größerer Geschwindigkeit.In conventional mechanics, gears and motor gears are not wear-free executed because of their touching ball bearings and gears. In addition, the mechanical resistance and loss at higher speeds.
Bei meiner Erfindung jedoch wird das Problem mit Magnetscheiben gelöst, die unterschiedlich magnetisiert sind. Die Welle, die den Träger der magnetisierten Zahnscheiben darstellt, wird durch einen Magnetstab ersetzt, der in Magnetbuchsen steckt, die die gleiche Polung besitzen (gleiche Pole stoßen sich ab). Ein Schneckengetriebe ist möglich, wenn man z. B. den Mittelpunkt mit dem Südpol magnetisiert und auf dem äußeren Zylinder eine Schnecke mit der Nordpol-Seite aufmagnetisiert. Der Vorteil ist, daß Stirnräder gegenüber den Kegelrädern keinen besonderen Kegelschliff benötigen, weil das Mangetfeld um die äußere Achse einer solchen Zahnscheibe wirkt. Da solche Zahnscheiben mehrfach gepolt sind, können einfach mehrere oder einfache Magnetspulen an der Antriebseite eines solchen Zahnradgetriebes angebracht werden, um dieses Zahnrad als Mehr- oder Einstrang-Schrittmotor zu betreiben. Auch kann eine Hälfte als Motor und die andere Hälfte als antreibendes Zahnrad genutzt werden. Auch können auch mehrere Zahnkränze zur Mitte hin auf einem solchen Zahn aufmagnetisiert sein, wobei ein Kranz als Schrittmotor ausgeführt sein kann.In my invention, however, the problem is solved with magnetic disks that are magnetized differently. The shaft that supports the magnetized tooth lock washer represents, is replaced by a magnetic rod that is inserted into magnetic sockets that are the same Have polarity (same poles repel each other). A worm gear is possible if you e.g. B. magnetized the center with the south pole and one on the outer cylinder Snail magnetized with the north pole side. The advantage is that spur gears over the Bevel gears do not need a special bevel cut because the Manget field around the outer Axis of such a pulley acts. Since such tooth lock washers are poled several times, can simply have multiple or simple solenoids on the drive side of such Gear transmission can be attached to this gear as a multi or single strand stepper motor to operate. One half can also be used as an engine and the other half as a driving gear can be used. Several sprockets can also go towards the center be magnetized on such a tooth, with a ring designed as a stepper motor can be.
In der Zeichnung Fig. 1 ist ein Beispiel eines solchen berührungslosen Getriebes 5 : 15 dargestellt. Fünf Doppelpole die Nr. 1 und fünfzehn Doppelpole die Nr. 2. Solche magnetisch abhängige Zahnräder können axial oder radial aufmagnetisiert sein. Die Vorteile sind, daß man die Werkstoffe, aus denen solche Zahnräder bestehen, mit Laser und Ätztechniken als Mikrogetriebe ausführen kann. (Auch Spulen kann man auf Halbleiter und Cu-Basismaterial in Ätztechnik ausführen. Der besondere Vorteil ist bei Hochgeschwindigkeits-Mikrozahnrädern, weil normalerweise sofort ein Verschleiß durch die hohe Umdrehung eintreten würde. Es kann auch als halbmechanisches Schaltgetriebe für die Autoindustrie ausgeführt sein, wobei von einem immer höher übersetzten Zahnrad auf ein solches magnetisch ineinander kämmendes berührungsloses System übergewechselt werden kann und innerhalb der berührungslosen bzw. sich in Hochgeschwindigkeit befindlichen Getriebeteile Umschaltungen, Bremsungs- und Kupplungsfunktionen durchführen und anschließend wieder kräftemäßig auf kraftvolle mechanische Zahnradtechnik untersetzt werden, um dann die Räder eines Kraftwagens anzutreiben. Auch kann man den Vorteil nutzen und ein solches Zahnrad als elektrisch umschaltbarer (wobei in Fig. 1 beide Zahnräder gleichzeitig umgeschaltet Nr. 1, Nr. 3 werden müßten, um die Umkreiszahnradabstände immer einzuhalten) Elektromagnetenkranz anzusehen ausführen, also von Weniger auf Mehrpolig, das wie ein Automatikgetriebe arbeitet, mit Hilfe von Elektronik umschalten.In the drawing Fig. 1 an example of such a contactless transmission 5:15 is shown. Five double poles the number 1 and fifteen double poles the number 2. Such magnetically dependent gearwheels can be magnetized axially or radially. The advantages are that the materials from which such gearwheels are made can be designed as a microgear with lasers and etching techniques. (Coils can also be made on semiconductors and Cu base material using etching technology. The particular advantage of high-speed microgears is that wear would normally occur immediately due to the high speed. It can also be designed as a semi-mechanical gearbox for the automotive industry, whereby from an increasingly high gear can be changed to such a magnetically intermeshing contactless system and perform switching, braking and clutch functions within the contactless or high-speed gear parts and then forcefully reduced to powerful mechanical gear technology, then the wheels one It is also possible to take advantage of such a gear as an electrically switchable one (whereby in FIG. 1 both gear wheels No. 1, No. 3 would have to be switched at the same time in order to keep the circumferential gear wheel distances) r to be observed) Perform the electromagnetic ring, i.e. switch from less to multi-pole, which works like an automatic transmission, with the help of electronics.
