Abstract

The machine has a connecting area formed by four regularly displaced spoke units between a bearing hub and an outer ring. The spoke units have rolling surfaces (13) for an insertable rolling body (14) which run in the form of a cut of a helical curve, where each surface exhibits a reverse orientation. A driving unit consisting of sub units (15A, 15B) is arranged for positioning on two sides of the spoke units. The sub units have rolling surfaces, which are counter surfaces to the rolling surfaces of the spoke units. The rolling body is connected as an intermediate element to the surfaces.

Description

Die Erfindung bezieht sich auf ein Bodenpflegegerät, wie Bohnergerät, mit einer rotierend antreibbaren Pflegescheibe, wobei ein Gestell einen Antrieb mit der Pflegeschreibe trägt sowie über Führungselemente am Boden verfahrbar abstützbar und die Pflegescheibe gegenüber dem Boden zur Einstellung des Anpreßdruckes unter Berücksichtigung der Bodenbeschaffenheit höhenveränderlich und der Antrieb mit einem in der Drehachse der Pflegescheibe rotierend gelagerten Antriebselement verbunden ist, das mit einem Abtriebselement für die Pflegeschreibe verbunden und das Abtriebselement gegenüber dem Antriebselement relativ zueinander verdrehbar und axial verschiebbar ist sowie über ein Spannelement eine höhenveränderliche Einstellung des Abtriebselementes durch Verdrehung unter Berücksichtigung der vorliegenden Verhältnisse einstellbar ist.The invention relates to a floor care device, such as Ringer, with a rotatably driven care disc, a frame carries a drive with the care writing and movable over guide elements on the ground supportable and the maintenance disc relative to the ground to adjust the contact pressure, taking into account the soil quality and the Drive is connected to a rotatably mounted in the axis of rotation of the care disk drive element which is connected to an output element for the care writing and the output element relative to the drive element rotatable relative to each other and axially displaceable and a tensioning element a height adjustable adjustment of the output element by rotation taking into account the present Ratios is adjustable.

Geräte dieser Art sind nach der DE 198 57 628 A1 bereits bekannt und dienen dazu, die Pflegescheibe entsprechend der Bodenbeschaffenheit selbsttätig höhenverstellbar anzuordnen, um keine Beschädigung der Bodenfläche herbeizuführen und ein kontinuierliches Arbeitsergebnis mit einem überlastfreien Antrieb zu gewährleisten. Es hat sich aber gezeigt, daß die Übertragungselemente zur selbständigen Höheneinstellung für einen robusten dauerhaften Betrieb, wie es bei einem gewerblichen Einsatz der Fall ist, der Verstellmechanismus schwierig zu gestalten ist, um eine verschleißfreie Ausbildung mit einfacher Montage zu ermöglichen.Devices of this kind are after the DE 198 57 628 A1 already known and serve to arrange the care disc according to the soil condition automatically height adjustable to cause no damage to the bottom surface and to ensure a continuous work result with a overload-free drive. However, it has been found that the self-leveling transfer elements for robust, durable operation, as is the case in a commercial application, the adjustment mechanism is difficult to design to allow a wear-free design with ease of installation.

Die Aufgabe der Erfindung ist es, ein gattungsgemäßes Gerät mit einer robusten Ausbildung zu schaffen und eine Höheneinstellung einer Pflegescheibe auf einfache weise mit einem Spielausgleich und einer Minimierung der Bauteile zu ermöglichen sowie eine einfache Montage zu gewährleisten.The object of the invention is to provide a generic device with a robust design and to enable a height adjustment of a care disc in a simple way with a clearance compensation and minimization of components and to ensure easy installation.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, dass das Antriebselement eine Lagernabe mit einem zugeordneten Außenring für eine Antriebsmittelverbindung aufweist und ein Verbindungsbereich über mindestens vier regelmäßig versetzte Speichenelemente zwischen Lagernabe und Außenring gebildet ist, wobei die Speichenelemente jeweils eine Abrollbahn für einsetzbare wälzkörper aufweisen, die jeweils in Form eines Teilausschnittes einer Schraubenlinie um die Achse verlaufen und rotatorisch benachbarte Abrollbahnen jeweils eine umgekehrte Orientierung aufweisen und das Abtriebselement aus zusammensetzbaren Teilelementen zur beidseitigen Zuordnung zu den Speichenelementen angeordnet ist und die aufgesetzten Teilelemente jeweils korrespondierende Abrollbahnen als Gegenbahnen zu den Abrollbahnen der Speichenelemente aufweisen und Wälzkörper als Zwischenelemente den Abrollbahnen zugeordnet sind.The solution of this object is achieved according to the invention in that the drive element has a bearing hub with an associated outer ring for a drive means connection and a connection region is formed over at least four regularly offset spoke elements between bearing hub and outer ring, wherein the spoke elements each have a rolling track for usable rolling elements, each in the form of a partial section of a helical line run around the axis and rotationally adjacent rolling tracks each have a reverse orientation and the output element is composed of composable sub-elements for assignment to the spoke elements on both sides and the patch sub-elements respectively corresponding rolling tracks as opposite paths to the rolling tracks of Having spoke elements and rolling elements are associated with the rolling tracks as intermediate elements.

Somit ist es möglich, gleiche Teile einzusetzen und eine störungsfreie Funktion mit geringer Anzahl von Bauteilen sowie einfacher Montage zu ermöglichen. Es wird damit eine sich selbst blockierende kardanische Aufhängung mit einer dauerhaften Spielfreiheit ermöglicht. Über die gebildete Ausrichtung ist eine Ausrichtung der Kräfteübertragung auf die Wälzkörper senkrecht zur Schraubenlinie durchführbar.Thus, it is possible to use the same parts and to allow trouble-free operation with a small number of components and easy installation. It is thus possible a self-locking gimbal with a permanent backlash. About the alignment formed an alignment of the transmission of forces on the rolling elements is perpendicular to the helix feasible.

Ferner ist vorgesehen, daß die Abrollbahnen intermittierend auf entgegengesetzten Seiten der Speichenelemente angeordnet sind.It is further provided that the rolling tracks are arranged intermittently on opposite sides of the spoke elements.

Um einen Spielausgleich zu schaffen, wird vorgeschlagen, daß die Teilelemente zur beiderseitigen Zuordnung zu den Speicherelementen über Befestigungselemente unter Zwischenschaltung von Federn gekoppelt sind.In order to create a clearance compensation, it is proposed that the sub-elements are coupled for mutual assignment to the storage elements via fastening elements with the interposition of springs.

Eine vorteilhafte Ausbildung wird dadurch geschaffen, daß die Abrollbahnen aus verschleißfestem Sinter-Werkstoff bestehen, die in die Speichenelemente und/oder in die Teilelemente einsetzbar sind.An advantageous embodiment is provided in that the rolling tracks made of wear-resistant sintered material, which can be used in the spoke elements and / or in the sub-elements.

Weiterhin ist vorgesehen, daß zwischen Abtriebselement und Antriebselement eine axial und rotatorisch bewegliche Dichtung angeordnet ist.Furthermore, it is provided that an axially and rotationally movable seal is arranged between the output element and drive element.

Eine einfache Ausbildung wird dadurch erreicht, daß die Abrollbahnen als Gleichteile ausgebildet sind.A simple design is achieved in that the rolling tracks are designed as equal parts.

Ferner wird vorgeschlagen, daß die Befestigungselemente mit den Federelementen im Winkel entsprechend der auf die Abrollbahnen wirkenden Wälzkörperkräfte angeordnet sind.It is also proposed that the fastening elements are arranged with the spring elements at an angle corresponding to the Wälzkörperkräfte acting on the rolling tracks.

Die Abrollbahnen 13 sind dabei jeweils in Form eines Teilausschnittes einer Schraubenlinie um die Mittelachse ausgerichtet und damit ist eine Drehführung für eine Höhenverstellung eines zugeordneten Abtriebelementes 15 für die zugeordnete Pflegescheibe 4 gebildet. Hierbei ist das Abtriebselement 15 über eine Feder 16 in Ausstellrichtung beaufschlagt.The offset by 90 degrees arranged spoke elements 10 have rolling tracks 13 as inserts for rolling elements 14, which have intermittently on adjacent spoke elements 10 each have a reverse orientation on opposite sides. The rolling tracks 13 are each aligned in the form of a partial section of a helix about the central axis and thus a rotary guide for a height adjustment of an associated output element 15 for the associated care disc 4 is formed. Here, the output element 15 is acted upon by a spring 16 in Ausstellrichtung.

Um die Drehführung des Abtriebselementes 15 über die Abrollbahnen 13 durchzuführen, ist das Abtriebselement 15 durch zwei zusammensetzbare Teilelemente 15A und 15B gebildet, die zur beidseitigen Zuordnung zu den Speichenelementen 10 angeordnet sind und die aufgesetzten Teilelemente 15A und 15B des Abtriebselementes 15 jeweils korrespondierende Abrollbahnen 13 der Speichenelemente 10 unter Einschluß von aufgenommenen Wälzkörpern 14 aufweisen.In order to carry out the rotational guidance of the driven element 15 via the rolling tracks 13, the output element 15 is formed by two composable sub-elements 15A and 15B, which are arranged for two-sided assignment to the spoke elements 10 and the attached sub-elements 15A and 15B of the output element 15 respectively corresponding rolling tracks 13 of Having spoke elements 10 including included rolling elements 14.
