Abstract

The propulsion unit, in particular, with at least one cycloidal propeller, for a ship comprises an auxiliary motor (3) whose torque is transmitted to the bevel wheel (6) of the drive drum (18) via a bevel pinion (5) made of a noise insulating material.

Description

Die Erfindung betrifft einen Schiffsantrieb entsprechend dem Oberbegriff des Patentanspruchs 1. Ein solcher Antrieb ist beschrieben in VOITH - "Forschung und Konstruktion", Heft 18, Aufsatz 3, Mai 1967. Bei dem dort dargestellten Zykloidalpropeller findet man auch die Darstellung einer Lagerung des Antriebsritzels des Kegelradgetriebes am Propellergehäuse dargestellt.The invention relates to a ship drive according to the preamble of claim 1. Such a drive is described in VOITH - "Research and Construction", Issue 18, Article 3 , May 1967. In the cycloidal propeller shown there is also the representation of a bearing of the drive pinion Bevel gear shown on the propeller housing.

Beim Antrieb von Spezialschiffen wird in den meisten Fällen ein zusätzlicher Hilfsantrieb benutzt, um bei bestimmten Einsätzen, wie es z. B. bei einem Minensuchboot erforderlich ist, die Geräusche ganz erheblich zu reduzieren. Dabei wird im allgemeinen über ein Verzweigungsgetriebe, im einfachsten Fall ganz einfach ein Riementrieb, der Hilfsantrieb auf das Antriebsritzel des Kegelradgetriebes geschaltet. Der Hauptmotor wird dann über eine Schaltkupplung von dem Antrieb abgeschaltet. Mit einer solchen Maßnahme kann jedoch die Geräuschdämpfung nicht zufriedenstellend erreicht werden.In most cases, the drive of special ships is an additional Auxiliary drive used to in certain operations, such as. B. at one Minecraft is required to reduce the noise significantly. It is generally a branching gear, in the simplest case simply a belt drive, the auxiliary drive on the drive pinion of the Bevel gear switched. The main engine will then have a Switching clutch switched off by the drive. With such a measure however, the noise reduction cannot be achieved satisfactorily.

Die Aufgabe der Erfindung ist es daher, ein Antriebskonzept mit wesentlich besserer Geräuschdämpfung anzugeben.The object of the invention is therefore to provide a drive concept with essential to provide better noise reduction.

Zur Lösung dieser Aufgabe wird auf Patentanspruch 1 verwiesen.To solve this problem, reference is made to claim 1.

Man hat hierbei den Vorteil, daß das Tragbild des zusätzlichen Ritzels optimal der geringeren Belastung angepaßt werden kann. Ein weiterer Vorteil ergibt sich dadurch, daß man die Kupplung zwischen Hilfsantrieb und zusätzlichem Antriebsritzel wesentlich elastischer ausführen kann als in bekannten Antriebslösungen.The advantage here is that the contact pattern of the additional pinion is optimal can be adapted to the lower load. Another advantage results yourself in that the coupling between auxiliary drive and additional Drive pinion can run much more elastic than in known Drive solutions.

Da das Zusatzritzel für eine wesentlich kleinere Belastung, z. B. nur 15% der Nennleistung bzw. ca. 25% des Nenndrehmomentes ausgelegt werden muß, kann es ohne weiteres aus gut geräuschdämmendem Material gefertigt werden, wie z. B. Kunststoffe, die auch in Verbundbauweise mit Stahl oder Titan hergestellt werden können.Since the additional pinion for a much smaller load, for. B. only 15% of Rated power or approx. 25% of the nominal torque must be designed, it can easily be made from good noise-insulating material  be such. B. plastics, also in composite construction with steel or Titan can be made.

Nachfolgend wird die Erfindung anhand der beigefügten Zeichnung erläutert. Die Zeichnung zeigt eine prinzipielle Anordnung eines erfindungsgemäßen Schiffsantriebes.The invention is described below with reference to the accompanying drawing explained. The drawing shows a basic arrangement of a Ship propulsion according to the invention.

Wie man sieht, umfaßt der Zykloidalpropeller eine Antriebstrommel 18 sowie einen Rotorkörper 16. Dieser trägt die Propellerflügel 17. Man erkennt ferner die Lager 19 und 20. Lager 19 ist im allgemeinen ein Kugellager, und Lager 20 im allgemeinen ein Gleitlager.As can be seen, the cycloidal propeller comprises a drive drum 18 and a rotor body 16 . This carries the propeller blades 17 . Bearings 19 and 20 can also be seen. Bearing 19 is generally a ball bearing, and bearing 20 is generally a plain bearing.

An der Antriebstrommel 18 ist das Tellerrad 6 des Kegelradgetriebes befestigt.The ring gear 6 of the bevel gear is attached to the drive drum 18 .

Im Hauptantriebswellenstrang befinden sich der Hauptantriebsmotor 1, eine Schaltkupplung 15, ein Getriebe 8, eine elastische Kupplung 7 sowie das von den Lagern 9 getragene Hauptantriebsritzel 2.The main drive shaft 1 contains the main drive motor 1 , a clutch 15 , a transmission 8 , an elastic coupling 7 and the main drive pinion 2 carried by the bearings 9 .

Das zweite Ritzel 5 des Hilfsantriebsstranges wird von den Lagern 10 getragen. Lager 9 und 10 werden ihrerseits gehalten von dem hier mit 36 angedeuteten Gehäuse des Propellers. Im Hilfsantriebsstrang befinden sich der Hilfsmotor 3 und ein Getriebe 14, die beide mittels Federn 12 auf dem Fundament 13 des Schiffes gelagert sind. Ferner ist eine hochelastische Kupplung 4 zwischen dem zweiten Ritzel 5 und dem Getriebe 14 eingeschaltet. Diese Kupplung ist hochelastisch ausgebildet, insbesondere durch Gummielemente, wie später noch erläutert wird. Wie schon ausgeführt, muß das zweite Ritzel 5 nur eine verhältnismäßig geringe Belastung aushalten, weshalb es ohne weiteres aus einem stark geräuschdämmenden Werkstoff, wie z. B. Kunststoff, hergestellt werden kann. Solche Grundstoffe sind z. B. Polyamid oder Polyimidamin. Eine Verbundbauweise mit Fäden aus Stahl oder Titan ist möglich. Vorzugsweise wird der E-Modul des geräuschdämmenden Werkstoff des Ritzels 5 höchstens das 0,2-fache von dem des Stahls betragen.The second pinion 5 of the auxiliary drive train is carried by the bearings 10 . Bearings 9 and 10 are in turn held by the housing of the propeller indicated here by 36. In the auxiliary drive train are the auxiliary motor 3 and a gear 14 , both of which are supported by springs 12 on the foundation 13 of the ship. Furthermore, a highly elastic coupling 4 between the second pinion 5 and the transmission 14 is switched on. This coupling is designed to be highly elastic, in particular by means of rubber elements, as will be explained later. As already stated, the second pinion 5 only has to withstand a relatively low load, which is why it is readily made of a highly noise-insulating material such as. B. plastic can be produced. Such raw materials are e.g. B. polyamide or polyimidamine. A composite construction with threads made of steel or titanium is possible. Preferably, the modulus of elasticity of the noise-reducing material of the pinion 5 will be at most 0.2 times that of the steel.

Die hochelastische Kupplung kann in verschiedensten Ausführungsformen angewendet werden, wie sie z. B. in dem Fachbuch Hütte II A, des Ingenieurstaschenbuchs, enthalten sind. Es wäre vielleicht noch zu ergänzen, daß in der dargestellten Ausführungsform der grundsätzlichen Antriebsanordnung eine Schaltkupplung im Hilfsstrang nicht vorgesehen ist. Dies ist dann möglich, wenn man z. B. den Hilfsmotor 3 als Elektromotor oder Hydromotor ausbildet, der dann ohne weiteres mit dem Getriebe im Fall des eingeschalteten Hauptantriebes sozusagen "unten leer" mitläuft.The highly flexible coupling can be used in various embodiments, such as. B. are contained in the specialist book hut II A, the engineering pocket book. It could perhaps be added that in the illustrated embodiment of the basic drive arrangement, a clutch is not provided in the auxiliary line. This is possible if, for. B. forms the auxiliary motor 3 as an electric motor or hydraulic motor, which then runs along with the gearbox in the case of the main drive being switched on, so to speak "bottom empty".

Es erscheint noch folgender Hinweis angebracht: Da bei Betrieb des Hilfsmotors das Ritzel 2 im Hauptstrang mit umläuft, könnte vorgesehen werden, daß dessen Rückflanke ebenfalls mit einem geräuschdämmenden Werkstoff, z. B. also mit einem Kunststoff, beschichtet wird.The following note appears to be appropriate: Since the pinion 2 rotates in the main line when the auxiliary motor is operating, it could be provided that the rear flank of the pinion 2 is also made with a sound-absorbing material, e.g. B. is coated with a plastic.
