Description

Elektrische Bohnermaschine Dem Hauptpatent 550 36o liegt die Aufgabe zugrunde, bei elektrischen Bohnermaschinen, deren Motor durch ein Reibritzel eine an der Tellerbürste befestigte Reibscheibe antreibt, den meist aus Gummi bestehenden Reibscheiben- und Ritzelbelag zu schonen. Zu diesem Zweck wird nach dem Hauptpatent der Zug der das Reibritzel des Motors an die Reibscheibe pressenden Feder bei Außerbetriebsetzung der Maschine dadurch unwirksam gemacht, daß der Motor von einem Hebel o. dgl. entgegen der Wirkung der Feder von der Reibscheibe abgehoben wird. Hierbei kommt das Reibritzel mit der Reibscheibe zwar ganz außer Berührung, aber. die Feder wird zusätzlich gespannt, so daß eine frühzeitige Ermüdung der Feder eintritt, Es hat sich nun gezeigt, daß es genügt, den Zug der das Reibritzel des Motors an die Reibscheibe pressenden . Feder dadurch unwirksam zu machen, daß sie bei Außerbetriebsetzung der Bohnermaschine mittels einet geeigneten Vorrichtung entspannt wird. Hierbei bleibt zwar das Reibritzel des Motors auf der Reibscheibe liegen, aber da der Anteil des Motorgewichtes an dem von dem Reibritzel auf die Reibscheibe ausgeübten Druck gegenüber der Federpressung nur gering ist, beispielsweise nur Zoo g gegenüber 3, i kg Federdrugk, so erfolgt nur eine Linienberiihrung zwischen Ritzel und Reibscheibe, die keinerlei Schaden an dem durch den Betrieb erhitzten Reibscheiben- und Ritzelbelag verursacht. Infolge der Entspannung der Feder im Ruhezustand der Bohnermaschine wird eine frühzeitige Ermüdung der Feder, wie sie beim Hauptpatent eintritt, vermieden.Electric floor polishing machine The main patent 550 36o is based on the task of protecting the friction disc and pinion lining, which is usually made of rubber, in electric floor polishing machines, the motor of which drives a friction disc attached to the plate brush by means of a friction pinion. For this purpose, according to the main patent, the train of the spring pressing the friction pinion of the motor against the friction disk when the machine is shut down is rendered ineffective in that the motor is lifted from the friction disk by a lever or the like against the action of the spring. Here, the friction pinion comes out of contact with the friction disk, but. the spring is additionally tensioned, so that the spring will tire prematurely. It has now been shown that it is sufficient to pull the tension of the friction pinion of the motor against the friction disc. To make the spring ineffective in that it is relaxed by means of a suitable device when the floor polishing machine is shut down. The friction pinion of the motor remains on the friction disc, but since the proportion of the motor weight in the pressure exerted by the friction pinion on the friction disc is only small compared to the spring pressure, for example only zoo g compared to 3.1 kg of spring drug, only one takes place Line contact between the pinion and the friction disc, which does not cause any damage to the friction disc and pinion lining heated by operation. As a result of the relaxation of the spring when the floor polishing machine is at rest, premature fatigue of the spring, as occurs in the main patent, is avoided.

Die Entspannungsvorrichtung für dieFeder kann von einem am Motor drehbar gelagerten Hebel gebildet werden, an dem das eine Ende der Feder in geeigneter Entfernung von seinem Drehpunkt befestigt ist. Es sind jedoch auch andere Lösungen denkbar, z. B. durch Zurückdrehen einer Flügelmutter, die auf das mit Gewinde versehene eine Ende der Feder aufgeschraubt ist.The relaxation device for the spring can be rotated by one on the motor mounted lever are formed on which one end of the spring at a suitable distance is fixed by its pivot point. However, other solutions are also conceivable, z. B. by turning back a wing nut on the threaded one End of the spring is screwed on.

Auf der Zeichnung ist eine Ausführung der Erfindung beispielsweise dargestellt, und zwar zeigt Fig. i eine Ansicht der elektrischen Bohnermaschine mit gespannter Zugfeder, Fig:2 eine gleiche mit entspannter Zugfeder.An embodiment of the invention is shown in the drawing, for example shown, namely Fig. i shows a view of the electric polishing machine with a tensioned tension spring, Fig: 2 the same with a relaxed tension spring.

Die Tellerbürste i nach Fig. i und 2 wird von dem Motor 2, der mit seinem Reibritzel 3 mit der an der Tellerbürste befestigten Reibscheibe 4 in Eingriff steht, angetrieben. Der Motor 2 ist beweglich in einem Traggestell 5 gelagert. An dem Traggestell 5 ist gleichzeitig ein Rahmen 6 beweglich angeordnet, der um eine mit Rollen 7 versehene Welle 8 drehbar ist. An der Welle 8 greift eine Lenkstange 9 an. An dem Traggestell 5 ist das eine Ende einer Zugfeder io gelagert, deren anderes Ende mit einem einarmigen Hebel I I gelenkig verbunden ist. Der Hebel i.i ist an dem Motor 2 _ drehbar gelagert.The circular brush i according to FIGS. I and 2 is driven by the motor 2 which, with its friction pinion 3, engages with the friction disk 4 attached to the circular brush. The motor 2 is movably mounted in a support frame 5. At the same time, a frame 6 is movably arranged on the support frame 5 and is rotatable about a shaft 8 provided with rollers 7. A handlebar 9 engages the shaft 8. One end of a tension spring io is mounted on the support frame 5, the other end of which is articulated to a one-armed lever II. The lever ii is rotatably mounted on the motor 2 _.

Im Ruhezustande der Maschine nimmt der Hebel die in Fig.2 dargestellte aufrechte Lage ein, bei der die Feder io entspannt ist. Das Reibritzel 3 liegt dann nur mit dem geringen Anteil des Motorgewichtes auf der Reibscheibe auf. Dieser Druck des Motorgewichtes ergibt jedoch nur eing unschädliche Linienberührung zwischen Ritzel und Reibscheibe.When the machine is at rest, the lever takes the position shown in FIG upright position in which the spring is relaxed. The friction pinion 3 is then only with the small portion of the engine weight on the friction disc. This pressure of the engine weight, however, only results in a harmless line contact between Pinion and friction disc.

Im Betriebe wird der Hebel i i in die in Fig. i dargestellte Lage umgelegt und dabei die Feder io gespannt, so daß das Ritzel 3 fest gegen die Reibscheibe q. gepreßt wird. Die Endlage ist durch Anlage der Federaufhängung an dem Hebel i i bestimmt, kann aber auch durch einen Anschlag festgelegt werden. Eine besondere Sicherung ist nicht erforderlich, da die Feder in der Endlage des Hebels über ihre Strecklage hinausgeschwenkt ist.In operation, the lever i i is in the position shown in FIG folded over while tensioning the spring io, so that the pinion 3 firmly against the friction disc q. is pressed. The end position is achieved by applying the spring suspension to the lever i i determined, but can also be determined by a stop. A special Securing is not required because the spring is in the end position of the lever over its Extended position is pivoted out.
