Kurbelgehäuseoberteil gebildet ist und die andere In weiterer Ausführung der Erfindung kann die Gchäusehlllfte aus dem Kurbelgehäuseunterteil be- ίο Anlaßvorrichtung so ausgebildet sein, daß ein parsteht und die Trennfuge beider Gehöusehälften in allel zur Zylinderlängsachse verschiebbares Zahnrad der Kurbelwellcnlängsachse verläuft und welches zur in seiner einen Endlage mit einem Zahnkranz im Aufnahme einer einteiligen Kurbelwelle und einer Eingriff steht, der stirnseitig mit dem Lüfterrad fest fliegend auf dieser gelagerten Pleuelstange ein- verbunden ist. Diese Ausbildung der Anlaßvorrichgerichtet ist. . 15 tung gestattet ein sicheres Übertragen der Anlaß-Aus der USA.-Patentschrift 2 881744 ist bereits energie auf die Brennkraftmaschine, ohne daß damit eine Brennkraftmaschine, bestehend aus einem im zusätzlich weitere Einzelteile erforderlich sind,
wesentlichen zweiteiligen Gehäuse und einem auf der In der Zeichnung ist ein Ausführungsbeispiel der Kurbelwelle angeordneten Lüfterrad, bekannt. Die Erfindung dargestellt.The invention relates to a two-part housing for housing shells containing individual units, an air-cooled internal combustion engine for driving faster, time-saving and cost-saving removal and removal of work equipment, such as lawnmowers and hedge construction. The according to the invention scissors, SprühgerBten or the like, with an internal combustion crankshaft obtained on the corresponding embodiment, a cooling air machine, has only small structural dimensions, guidance parallel to the cylinder and a starter, is doggy and of only minor importance Weight, what device, in which housing the one housing - a decisive advantage for internal combustion engines half essentially through the cylinder and that in particular in the Gerlite sector.
The crankcase upper part is formed and the other a toothed ring is in the receptacle of a one-piece crankshaft and an engagement which is connected to the fan wheel on the front side so that it is overhung on this mounted connecting rod. This training is the starting device. . 15 device allows reliable transmission of the start-up from the USA.-Patent 2 881744 is already energy on the internal combustion engine, without an internal combustion engine consisting of an additional individual parts are required,
essential two-part housing and a fan wheel arranged on the I n of the drawing, an embodiment of the crankshaft is known. The invention illustrated.
einstückig gegossen, das Luftführungsunterteil und Zwischen dem Zylinderkopf und dem der die Aufnahmevorrichtung für die Lagerung der An- 55 Wandung des Luftführungsoberteils 5 ist eine Blechlaßvorrichtung bildet, die gleichachsig oder parallel- oder Kunststoff-Verkleidung 24 eingebracht. In dem achsig mit dem Zylinder zwischen dem Kurbel- dadurch gebildeten freien Raum kann beispielsweise gehäuse und der Luftführung angeordnet ist. Eine ein Behälter, eine Batterie 25 od. dgl. angeordnet Brennkraftmaschine mit einem derart ausgebildeten sein,
zweiteiligen Gehäufte hat den Vorteil, auf Grund der 60not provided, which is why this internal combustion engine is started between the two bearing points 16 and 17 by means of a crankshaft 11 fitted onto the crankshaft end and the ignition interrupter hand crank. cams 18 arranged and fixed to the crankshaft The object of the invention is to create a fan wheel 14 connected to the internal combustion engine 45 11 transmits the lathe housing, which by moving over the crankshaft 11 and the crankshaft size simplicity in construction and a total of small cheek 23 on the flying on the crank pin 19 distinguishes technical effort. According to the invention mounted connecting rod 20 and the piston 21, which is achieved in that the air flow starts through the internal combustion engine. The mower is arranged on the crankshaft output side, furthermore 50 knife 22 is attached to the output side end of the crank, the one housing half, with the cooling air duct, single shaft 11. Instead of the mower blade 22, it is cast as a single piece, which forms the upper part of the air duct and, of course, the other half of the housing, with the tools for the cooling air duct, can also be permanently attached at this point.
Cast in one piece, the air duct lower part and between the cylinder head and the receiving device for mounting the wall of the air duct upper part 5 forms a sheet metal letting device which is coaxial or parallel or plastic cladding 24. In the free space axially formed with the cylinder between the crank, for example, the housing and the air duct can be arranged. A container, a battery 25 or the like. Arranged internal combustion engine with such a design,
two-part heap has the advantage, due to the 60
teile keine komplizierten Formen aufzuweisen, wodurch wegen der einfachen und kostensparenden 1. Zweiteiliges Gehäuse für eine luftgekühlte Fertigung der einzelnen Gehäusehälften insgesamt Brennkraftmaschine zum Antrieb von Arbeitsnur geringe Herstellungskosten anfallen. Zusätzliche 65 geräten, wie Rasenmähern, Heckenscheren, Vorteile ergeben sich bei Reparaturen dadurch, daß Sprühgeräten od. dgl., mit einem auf der Kurbelwegen der einzigen vorhandenen Trennfuge des welle angeordneten LUfterrad, einer KUhlluft-Gehäuses und der einstückig alle erforderlichen führung parallel zum Zylinder und einer Anlaß-sensible arrangement and design of the individual claims:
parts do not have complicated shapes, whereby because of the simple and cost-saving 1. Two-part housing for an air-cooled production of the individual housing halves as a whole, the internal combustion engine for driving labor only incurs low manufacturing costs. Additional 65 devices, such as lawnmowers, hedge trimmers, advantages arise during repairs in that sprayers or the like, with an air wheel arranged on the crank paths of the only existing parting line of the shaft, a cooling air housing and the one-piece all necessary guide parallel to the cylinder and an occasion
