Description

Die Erfindung betrifft eine staubsaugende Bohnermaschine mit Reibrollenantrieb. Um eine Beschädigung der Motorwelle -zu verhindern, berührt nach dem Hauptpatent die Antriebsreibrolle die Bürstenantriebsscheiben nur mit ihrem über die Motorwelle vorstehenden Teil. Gemäß der weiteren Erfindung wird der Abrieb der Antriebsreibrolle durch die Bürstenantriebsscheiben dadurch verringert, daß die Reibrolle an ihrem Umfang im Bereich der Bürstenantriebsscheiben mit einem Kordelgewinde versehen ist. Versuche haben zu dem überraschenden Ergebnis geführt, :da, das Kordelgewinde die Reibflächen der Antriebsscheiben rein hält. Auch wird - die Gefahr des D_ urchrutschens des Antriebes verringert.The invention relates to a vacuum-cleaning floor polishing machine with a friction roller drive. To prevent damage to the motor shaft, touches according to the main patent the drive friction roller the brush drive pulleys only with their over the motor shaft protruding part. According to the further invention, the abrasion of the drive friction roller reduced by the brush drive pulleys that the friction roller on her Perimeter in the area of the brush drive pulleys is provided with a cord thread. Tests have led to the surprising result: there, the cord thread the Keeps the friction surfaces of the drive pulleys clean. Also - the danger of slipping through of the drive is reduced.

In der Zeichnung ist die Irrfindung beispielsweise veranschaulicht, und zwar zeigt diese einen Axialschnitt durch den Antriebsteil einer staubsaugenden Bohnermaschine.In the drawing, the mistake is illustrated, for example, namely, this shows an axial section through the drive part of a vacuum cleaner Floor polisher.

Auf der Welle i eines Elektromotors 2 sitzen ein Flügelrad 3 und eine Reibrolle 4. Die Reibrolle durchsetzt eine Gehäusewand 5 und ragt mit dem Teil ihrer Länge, der die Motorwelle überragt, zwischen mit Gummi od. dgl. belegte Antriebsscheiben 6 für die Bohnerbürsten 7. Über die Rolle 4 werden in bekannter Weise die Bohnerbürsten in Drehung versetzt.An impeller 3 and an impeller are seated on the shaft i of an electric motor 2 Friction roller 4. The friction roller penetrates a housing wall 5 and protrudes with part of it Length that protrudes beyond the motor shaft, between drive pulleys covered with rubber or the like 6 for the polishing brushes 7. The polishing brushes are placed over the roller 4 in a known manner set in rotation.

Das vorstehende Ende io der Welle i ist kegelig ausgebildet und ragt in einen entsprechenden Hohlkegel der Rolle 4. Eine axial in der Rolle angeordnete Schraube i i preB-t- die Rolle auf die Welle. Der Kopf der Schraube ii sitzt versenkt in einer stirnseitigen Bohrung i2 der Rolle.The protruding end io of the shaft i is conical and protrudes into a corresponding hollow cone of the roller 4. An axially arranged in the roller Screw i i preB-t- the roller on the shaft. The head of screw ii is countersunk in an end bore i2 of the role.

Nach der Erfindung ist -die Rolle 4 an ihrem Umfang im Bereich der Bürstenantriebsscheiben 6 mit einem Kordelgewinde vorzugsweise geringer Steigung versehen.According to the invention, the roller 4 is at its periphery in the area of Brush drive pulleys 6 with a cord thread, preferably a low pitch Mistake.

Hat sich auf der Reibfläche der Antriebsscheiben beispielsweise durch Eindringen von Öl oder wachshaltigen Stoffen in das Gehäuse ein Belag gebildet; dann wird dieser Belag während des Betriebes durch das Kordelgewinde zur Seite abgedrängt. Das Kordelgewinde hält also die Reibflächen der -Antriebsscheiben sauber. Durch diese unerwartete Wirkung wird die Lebensdauer der Reibflächen .sowohl der Antriebsscheiben als auch der Reibrolle wesentlich erhöht. .Has developed on the friction surface of the drive pulleys, for example Penetration of oil or substances containing wax into the housing forms a coating; then this covering is pushed to the side by the cord thread during operation. The cord thread keeps the friction surfaces of the drive pulleys clean. By this unexpected effect will reduce the service life of the friction surfaces, as well as the drive pulleys as well as the friction roller increased significantly. .
