Description
Vorliegende Erfindung bezieht stich auf eine Dreschmaschine für Handbetrieb.The present invention relates to a threshing machine for manual operation.
Die bisherigen Bauarten -dieser Maschinengattung besitzen den Überstand, daß durch
die verwickelten Zahnrad- bziw. Kettenradübersetzungen große Reibungsverluste entstehen.,
was erhebliche Kraftvergeudungen zur Folge hat. Diese Nachteile werden durch
vorliegende Erfindung behoben.
ίο Das Kennzeichen der Erfindung besteht darin, daß zwischen Trommelritzel und Kurbelvorgelege
ein Übersetzuingsrad1 angeordnet ist, das mittels Rolilenverzahnung in das
Ritzel eingreift. Das Übersetaungsrad ist außen als Riemenscheibe ausgebildet behufs
Kraftubertragung von der Antriebkurbel oder Antriebriemenscheibe auf das Übersetzungsrad.
The previous types of this type of machine have the supernatant that, respectively, through the entangled gear. Sprocket gear ratios result in large friction losses, which results in considerable power being wasted. These disadvantages are overcome by the present invention.
ίο The characteristic of the invention is that a transmission gear 1 is arranged between the drum pinion and the crank gear, which engages in the pinion by means of roller teeth. The transmission wheel is designed on the outside as a belt pulley for the purpose of transmitting power from the drive crank or drive belt pulley to the transmission wheel.
•Abb. ι stellt einen Querschnitt durch den Antrieb dar, während Abb. 2 eine Seitenansicht der ganzen Dreschmaschine veranscbaiUiliidht. • Fig. ι represents a cross section through the drive, while Fig. 2 is a side view the whole threshing machine veranscbaiUiliidht.
α ist die Trommelwelle, b das Trommel- α is the drum shaft, b the drum
ritzel, c das Üibersetzungsrad, das sich uim den Zapfen g dreht und1 bei d als Riemenscheibe ausgebildet ist; k sind die Rollenzapfen und f die Rollen.pinion, c the transmission wheel that rotates uim the pin g and 1 at d is designed as a pulley; k are the roller journals and f are the rollers.
Die Wirkungsweise der beschriebenen Konstruktion ist wie folgt:
Die Kraftübertragung von der Antrieb-The mode of operation of the construction described is as follows:
The power transmission from the drive
kurbel i oder der Riemenscheibe h erfolgt diirch einen Riemen auf die Riemenscheibe d. Die in den Innenraum des Üibersetzungsrades c eingebaute Rd'lenverzahnung k, f steht 'mit dem Rollenritzel b in Eingriff. Die ganze Üiberseteung besteht also aus einem einzigen Riemenantrieb und aus einer einzigen Röllenverzahnung. Da sowohl der Riemenantrieb als auch die Rollenverzahnung sehr geringe Reibungsverluste bedingen, ist der Wirkungsgrad der gesamten Übersetzung sehr günstig.crank i or the pulley h is carried out diirch a belt on the pulley d. The internal gear teeth k, f built into the transmission wheel c mesh with the roller pinion b . The whole oversight consists of a single belt drive and a single roller toothing. Since both the belt drive and the roller teeth cause very low friction losses, the efficiency of the entire transmission is very favorable.
Ein weiterer Vorteil der bschriebenen Erfindung besteht darin, daß die Röllenverzahnung im Innenraum des Übersetzungsrades Hegt, wodurch besondere Schutzvorrichtungen in Wegfall kämmen. Die ganze Übersetzung ist außerordentlich einfach und übersichtlich. Zweckmäßig werden die Wellen- und Zapfenlagerungen noch mit Kugellagern ausgerüstet.Another advantage of the invention described is that the roller teeth in the interior of the transmission wheel, which means that special protective devices are no longer required. The whole translation is extremely simple and clear. The wave and journal bearings are still equipped with ball bearings.
