Es sind Schneckengetriebe bekannt, bei denen die seitlichen Ansätze einer mit der Schnecke zusammenarbeitenden Kette sich zwischen die Schneckengänge unter Führung durch Kettenräder einlegen, so daß von der Schnecke aus durch die Kette ein Kettenrad, das mit einer Arbeits'trommel verbunden ist, angetrieben werden kann. Dieses Getriebe benötigt viel Raum, ist umständlich im Aufbau, gestattetWorm gears are known in which the lateral approaches one with the worm cooperating chain is between the worm flights under the guidance of sprockets insert so that from the worm through the chain a sprocket with a Arbeits'trommel is connected, can be driven. This gearbox takes a lot Space, cumbersome to set up, is permitted
ίο keine .großen Übersetzungen und weist infolge seiner Bauart als Treibstockverzahnung hohe Flächendrucke auf.ίο no great translations and as a result its design as a drive stick gearing on high surface pressures.
Diese Nachteile sollen durch den Erfindungsgegenstand beseitigt werden. Dieser kennzeichnet sich dadurch, daß Gewindestücke in Form von zu einer Art von Gelenkkette vereinigten Gewindemutterstücken mit der Schnecke zum Eingriff gebracht und an der Eingriffstelle unter Verhinderung der Eigendrehung achsial geführt werden. Die Gewindestücke können dabei zu einer'Kette verbunden oder an einem Radträger gelagert sein.These disadvantages are intended to be eliminated by the subject matter of the invention. This indicates by the fact that threaded pieces in the form of combined to form a kind of link chain Threaded nut pieces brought into engagement with the worm and at the point of engagement guided axially while preventing their own rotation. The threaded pieces can be connected to a chain or mounted on a wheel carrier.
In der Zeichnung ist in den Fig. 1 und 2 die eine, und in den Fig. 3, 4 und 5 die andere Ausführung teils in Querschnitten, teils im Lagerschnitt und in Seitenansichten veranschaulicht. · 'In the drawing, FIGS. 1 and 2 show one, and FIGS. 3, 4 and 5 show the other Execution partly illustrated in cross-sections, partly in bearing section and in side views. · '
Wie aus Fig. 1 und 2 der ersten Ausführungsart hervorgeht, sind die Gewindemutterstücke α mittels Laschen b und Zapfen c zu einer Kette verbunden, die um ein Kettenrad dl und ein Führungsrad d2 geführt ist. Das Rad d1 ist zweiteilig ausgeführt. Die Gelenkzapfen c dienen zugleich als Triebstöcke.As can be seen from FIGS. 1 and 2 of the first embodiment, the threaded nut pieces α are connected by means of tabs b and pins c to form a chain which is guided around a chain wheel d l and a guide wheel d 2. The wheel d 1 is made in two parts. The pivot pins c also serve as headstocks.
Die Führung e zwischen den beiden Rädern d1, d2 verhindert die Eigendrehung der Gewindemutterstücke α bei ihrem Eingriff in die Schnecke f. Die Gewindemutterstücke α weisen Ausschnitte g auf, deren Breite etwas größer als der Kerndurchmesser der Schnecke ist, "wodurch die Muttern α leicht in und außer Eingriff mit den Schneckengängen f gelangen. The guide e between the two wheels d 1 , d 2 prevents the self-rotation of the threaded nut pieces α when they engage in the worm f. The threaded nut pieces α have cutouts g , the width of which is slightly larger than the core diameter of the worm, "whereby the nuts α easily get into and out of engagement with the worm threads f .
Bei dem Führungsbeispiel nach den Fig. 3 bis 5 sind die Gewindemutterstücke α mit den als Evolventzähne ausgebildeten Zapfen h in dem Doppelrad i gelagert und wälzen sich, ähnlich wie bei einem Zahnstangengetriebe, während des Durchgangs der Gewindestücke a durch die Schnecke f auf den Zähnen k, die durch Ausschnitte im Rade i entstanden sind, ab.In the guide example according to FIGS. 3 to 5, the threaded nut pieces α with the pins h designed as involute teeth are mounted in the double gear i and, similar to a rack and pinion gear, roll on the teeth k during the passage of the threaded pieces a through the worm f that were created by cutouts in the wheel i .
Das Einsetzen und Ausheben der umlaufenden Gewindemutterstücke α in die Schneckengänge f und aus ihnen erfolgt durch ortsfeste Kurvenscheiben I, in denen Nute» vorgesehen sind, die zur gradlinigen und zur Schneckenwelle parallelen Führung von mit den Muttern α fest verbundenen Zapfen oder Rollen r dienen. Auf dem vollen Kreisumfang der Scheiben I laufen ebenfalls mit den Muttern a fest verbunden Zapfen oder Rollen q. Die umlaufenden Radkränze i haben an jeder Seite eines jeden Mutterstückes α überkragende Zap-, fen η, auf denen sich die Muttern mittels der Führungen p heben und senken können. Dieses Heben und Senken ist erforderlich, um das Gradführen der Muttern α während, des Eingriffs der Schnecke zu ermöglichen.The insertion and removal of the rotating nut pieces α in the worm threads f and out of them is carried out by means of stationary cam disks I in which grooves »are provided, which serve to guide pins or rollers r firmly connected to the nuts α in a straight line and parallel to the worm shaft. On the full circumference of the disks I also run with the nuts a firmly connected pins or rollers q. The rotating wheel rims i have on each side of each nut piece α projecting pegs, pegs η on which the nuts can raise and lower themselves by means of the guides p. This raising and lowering is necessary in order to enable the nuts α to be guided straight during the engagement of the worm.
Die Kurvenscheiben I sind durch Schraubbolzen ,s am Maschinengestell befestigt und dadurch gegen Drehung gesichert.The cams I are fastened to the machine frame by screw bolts, s and are thus secured against rotation.
