Abstract
Description
Die Erfindung betrifft einen Reibradantrieb für eine Schiene, insbesondere an einem Schiebetor, die mit einer Lauffläche auf Tragrollen abgestützt gelagert ist und eine Reibfläche, die mindestens ein Reibrad kontaktiert und parallel zu dieser eine Reib- oder Stützfläche aufweist, die mindestens ein Reib- oder Stützrad kontaktiert, wobei die Reib- und/oder Stützräder zueinander beabstandet an einem Lagerschild jeweils zur zugehörigen Reib- oder Stützfläche hin einstellbar verschwenkbar an einer Stütze angeordnet sind und die Reibräder mit einem Antriebsmotor antriebsmäßig verbunden sind.The invention relates to a friction wheel drive for a rail, especially on a sliding gate with a tread on Carrying rollers is supported and a friction surface that contacted at least one friction wheel and parallel to this one Has friction or support surface, which has at least one friction or Support wheel contacted, the friction and / or support wheels spaced from each other on a bearing plate each Associated friction or support surface adjustable pivotable are arranged on a support and the friction wheels with a Drive motor are connected in terms of drive.
Eine derartige Vorrichtung ist aus der DE 94 180 79 U1 bekannt. Die Antriebsvorrichtung ist beabstandet zu einem bodenseitig gehaltenen Stützrollenlager in einem unten offenen C-Profil-Träger, der sich längs am Tor erstreckt, angeordnet und ist von einer sich unten aus dem C-Profil herauserstreckenden, bodenseitig fixierten Stütze getragen, an der schwenkbar um eine horizontale, senkrecht zur Trägererstreckungsrichtung Schwenkachse angelenkt ist. Um diese Schwenkachsen sind an der Antriebsvorrichtung mitschwenkbar obere Trag- und Reibrollen sowie untere Reibrollen gelagert, die den Profilträger oben bzw. unten tangieren und mit einem Getriebemotor antriebsmäßig verbunden sind. Durch die Lage der Reibrollenachsen relativ zur Schwenkachse verändert sich deren Höhenabstand und deren Andruckskraft beim Verschwenken. Die Andruckskraft der unteren Reibrollen wird insbesondere durch eine den Antrieb verschwenkend wirkende Feder erbracht. Dies ermöglicht einen Betrieb in jeder Verschiebelage des Tores, auch wenn sein Schwerpunkt sich über dem Stützrollenlager befindet oder abseitig des Antriebes über dieses hinausbefördert ist. Die oberen Reibräder haben jedoch zusätzlich zur Reibtriebbelastung die Stützlastbeanspruchung.Such a device is known from DE 94 180 79 U1. The drive device is spaced apart from one on the bottom Support roller bearing held in a C-profile beam open at the bottom, which extends along the gate, is arranged and is from one extending from the bottom of the C-profile, on the bottom fixed support, on which can be swiveled around a horizontal, articulated perpendicular to the direction of extension of the pivot axis is. Around these pivot axes are on the drive device also swiveling upper carrying and friction rollers as well as lower friction rollers stored, which touch the profile beam at the top or bottom and with a geared motor are connected. Because of the location the friction roller axes change relative to the swivel axis Height distance and their contact pressure when swiveling. The The pressure of the lower friction rollers is particularly influenced by provided the drive pivoting spring. this makes possible an operation in any sliding position of the gate, even if its Center of gravity is above the support roller bearing or to the side the drive is conveyed beyond this. The top Friction wheels, however, have in addition to the friction drive load Vertical load stress.
Reibradantriebe mit einem oder mehreren Reibrädern sind weiterhin aus der DE-OS 16 832 59 bekannt, die für einen Antrieb für freitragende Schiebetore eingesetzt werden. Bei diesen Reibradantrieben übernimmt mindestens ein Reibrad auch die Funktion einer Tragrolle. Dadurch kommt es bei sich verlagerndem Lastschwerpunkt im Verhältnis zu den Auflagepunkten der Tragrollen und der Reibräder zu unterschiedlichen Anpreßdrücken der Reibräder auf die Reibflächen. Die Andruckkraft und damit die mögliche Schubkraft auf das zu bewegende Tor verändert sich je nach Lage des Lastschwerpunktes erheblich und ist je nach der jeweiligen externen Abstützung auch stellenweise Null oder statt von oben nach unten von unten nach oben gerichtet.Friction wheel drives with one or more friction wheels are still from DE-OS 16 832 59 known for a drive for self-supporting sliding gates are used. With these Friction wheel drives also takes over at least one friction wheel Function of a support roller. This causes it to shift Center of gravity in relation to the support points of the idlers and the friction wheels at different contact pressures of the friction wheels on the friction surfaces. The pressure force and thus the possible Thrust on the door to be moved changes depending on the position of the center of gravity considerably and depends on the respective external support also zero in places or instead of from above directed downwards from the bottom upwards.
Es ist Aufgabe der Erfindung, den eingangs bezeichneten Antrieb so zu verbessern und zu vereinfachen, daß er von wechselnder Traglast nicht betroffen ist.It is an object of the invention, the drive described above to improve and simplify that of changing payload is not affected.
Die Lösung besteht darin, daß der Antriebsmotor an der Stütze gehalten ist und mit einem Umlaufantriebsmittel antriebsmäßig mit dem/den Reibrädern über Umlenkräder so verbunden ist, daß die Reib- und Stützräder sich gegenseitig an den Reib- und Stützflächen abstützen. Das zu verschiebende Objekt wird demgemäß unabhängig von der Antriebsvorrichtung linear geführt, und somit ist die Antriebsvorrichtung von einer in unterschiedlichen Verschiebestellungen auftretenden Lastverteilung auf die einzelnen Führungselemente unabhängig. Die Andruckkraft des Reibrades oder der Reibräder, die mit dem Vortriebsmotor in Verbindung stehen, erhält ihre abstützende Gegenkraft von der/den an der Führungsschiene gegenseitig tangierenden Stützrolle(n), die mit dem Reibrad auf einem Schwenkträger gelagert ist/sind, der so mit einem Schwenkmoment belastet ist, daß die Reib- und Gegenkraft an den Rollen entstehen. Das Schwenkmoment stammt von einer geeignet geführten Antriebskette oder einem Antriebsriemen, z.B. Zahnriemen, und/oder einer Spannfeder, die auch das umlaufende Antriebsmittel zum Antriebsrad des Motors unter Spannung hält.The solution is that the drive motor on the support is held and with a circulating drive means the friction wheel (s) is connected via deflection wheels so that the Friction and support wheels mutually on the friction and Support the support surfaces. The object to be moved accordingly guided linearly regardless of the drive device, and thus is the drive device of one in different Load distribution occurring on the individual Guide elements independent. The pressure force of the friction wheel or the friction wheels connected to the jacking motor, receives its supporting counterforce from the person (s) on the Guide rail mutually tangent support roller (s) with the friction wheel is / are mounted on a swivel bracket, which is with a pivoting moment is loaded that the friction and counterforce the roles arise. The swing moment comes from a suitable guided drive chain or a drive belt, e.g. Timing belt, and / or a tension spring, which is also the circumferential Drive means for the drive wheel of the motor keeps under tension.
Die Stütz- und Reibräder können einfach oder paarweise, insbesondere beidseitig der Zahnräder, angeordnet sein, und demgemäß in einem U- oder C-Profil einer Laufschiene untergebracht sein. Das Stützrad kann angetrieben sein, jedoch ist es vorzugsweise nur mitlaufend. Wegen der Reibbelastung ist das Reibrad vorzugsweise breiter ausgebildet als ein nicht angetriebenes Stützrad. das nur die Gegendruckkraft abrollend aufnimmt.The support and friction wheels can be single or in pairs, in particular on both sides of the gears, and accordingly housed in a U or C profile of a running rail his. The jockey wheel can be driven, but it is preferably only running. Because of the friction load it is Friction wheel preferably formed wider than a not driven jockey wheel. that just rolling off the counter pressure receives.
Die Riemenspannung und der Reibradandruck wird vorteilhaft federbelastet einstellbar auf den Schwenkträger der Rollen aufgebracht.The belt tension and the friction wheel pressure becomes advantageous adjustable on the swivel bracket of the rollers applied.
Der Motor ist an der feststehenden Stütze gehalten und von dessen Kettenritzel aus die Kette durch den Schlitz der Führungsprofilschiene zu den Zahnrädern geführt, von denen eines mit den Reibrädern verbunden ist und eines oder mehrere der Kettenumlenkung dienen, so daß die Kette mit ihrem Zug das Reibrad gegen die Reibfläche der Führungsschiene schwenkt. Kette und Riemen sind alternativ zu verwenden, wobei eine Umlenkrolle, die auf der zahnlosen Riemenseite anliegt, eine glatte Oberfläche ist.The motor is held on the fixed support and from the chain sprocket the chain through the slot of the Guide rail to the gears, one of which is connected to the friction wheels and one or more of the Serve chain deflection, so that the chain with its train the friction wheel pivots against the friction surface of the guide rail. Chain and Straps are alternatively to be used, with a pulley that on the toothless belt side, is a smooth surface.
Um bei Stromausfall den Antrieb in einen Freilauf verbringen zu können, ist ein Stellelement vorgesehen, das betätigt den Schwenkträger so verstellt, daß das Reibrad von der Reibfläche der Schiene freikommt. Bevorzugt ist ein Exzenter an einem Stellhebel vorgesehen, der selbsthemmend auf den Schwenkträger einwirkt. To freeze the drive in the event of a power failure can, an actuator is provided that actuates the Swivel bracket adjusted so that the friction wheel from the friction surface of the Rail is released. An eccentric on an actuating lever is preferred provided that acts self-locking on the swivel bracket.

insbesondere schwenkbar, ist. Die durch den Betrieb des
erfindungsgemäßen Reibradantriebes auftretenden Schub- und
Zugkräfte auf die Reibradträgereinheit 10 werden in einer Richtung
von der Antriebsrollenkette 11 und in der anderen Richtung von der
Verbindungsstange 14, die vorzugsweise eine Gewindespindel ist,
auf die ortsfeste Stütze 13 abgetragen. Der Kontakt zwischen den
Stütz- und Reibrädern 2, 2A; 3, 3A und den Stütz- und Reibflächen
30, 30A; 31, 31A wird durch Spannen der Rollenkette 11
hergestellt. Dazu ist die Rollenkette 11, wie in Fig. 1
dargestellt, wechselseitig um die Kettenräder 6, 7 geschlungen und
durch obenliegendes Umschlingen der an der ortsfesten Stütze 13
zwischen Wangen 13A gelagerten Umlenkrolle 12 und untenliegend des
Kettenrades 18 an der ortsfesten Stütze 13 abgestützt. Durch die
Einstellung des Abstandes zwischen der Stützwand 13B der
ortsfesten Stütze 13 und der Reibradträgereinheit 10 durch Drehen
der als Gewindespindel ausgebildeten Verbindungsstange 14, die
über eine an der Reibradträgereinheit 10 drehbar gelagerte Mutter
mit der Reibradträgereinheit 10 und deren andere Seite, gegen die
Spiralfeder 20 oder eine andere federnde Unterlage abgestützt, mit
der ortsfesten Stütze 13 gelenkig verbunden ist, wird die
Rollenkette 11 gespannt.The friction wheel drive according to the invention has the advantage that the
Die Abstützung der Führungsschiene 1 mit dem daran befestigten Tor
oder zu verschiebenden Objekt geschieht auf den bodenfest
gestützten Tragrollen 33, 34, von denen die eine neben der
Antriebseinheit dargestellt ist, was jedoch nicht zwingend ist.The support of the
Die mit dem Führungsglied 21 verschieblich und schwenkbar
gelagerte Reibradträgergruppe 10 ist durch die Kette 11, die
obenseitig über das freidrehende Kettenrad 12 geführt ist und
horizontal im Bild auf der anderen Seite der Führung 21 wie das
Kettenrad 6 des Reibrades 2 umgelenkt ist, mit einem solchen
Schwenkmoment um den Auflageort der Stützrolle 3 durch die
Kettenspannung belastet und durch die unten angreifende Zugkraft
der Spannfeder 20 belastet, daß die Reibung für den Antrieb der
Schiene 1 ausreicht, um das angeschlossene Tor zu verschieben.The slidably and pivotably with the
Um eine Entkoppelung des Antriebes vom Tor zu ermöglichen, ist ein
Exzenter 23 mit einem Stellhebel 25 an der Stütze 13 angeordnet,
der verschwenkt die Reibradgruppe 10 so verschwenkt, daß das
Reibrad 2, 2A von der Schiene 1 freikommt. Der Exzenterstellhebel
25 kann von Hand bedient werden und läßt sich auch zur
Notschaltung durch schienenseitige Anschläge nutzen.To enable the operator to be decoupled from the gate, a
Eccentric 23 arranged with an adjusting
Durch das Spannen der Rollenkette 11 wird die Reibradträgereinheit
10 soweit gekippt, bis die Reibräder an den Reibflächen 30, 31A
anliegen. Der für die Reibkraftübertragung notwendige Anpreßdruck
der Reibräder auf die Reibflächen wird durch weiteres Drehen der
Verbindungsstange 14 in dieselbe Richtung, wodurch die Spiralfeder
20 vorgespannt wird, stufenlos einstellbar erzeugt. Die
Antriebskraft vom Motor 15 wird über die Welle 16, das Kettenrad
18, die Rollenkette 11 auf die Kettenräder 6, 7 und von dort auf
die Wellen 4 auf die Reibräder oder Reibräderpaare 2, 2A
übertragen. Soll auch das Stützrad 3, 3A als Reibrad dienen, wird
die Verbindung zu dem Kettenrad 7 hergestellt.By tensioning the
Anstatt des Rollenkettenantriebes kann auch ein Zahnriemen-,
Flachriemen- oder Rundriemenantrieb eingesetzt werden. Der
erfindungsgemäße Reibradantrieb kann sowohl zum Antreiben von
freitragenenden Schiebetoren, als auch zum Antreiben von
Schiebetoren verwendet werden, deren Gewicht durch auf Schienen
laufende Tragrollen abgestützt ist. Selbstverständlich läßt sich
ein solcher Antrieb auch obenseitig oder seitlich an einem zu
verfahrenden Objekt anbringen, wobei er im allgemeinen mit der
Schienenöffnung vom Objekt weg gerichtet angeordnet ist. Der
erfindungsgemäße Reibradantrieb hat mindestens 2 - Figur 2 -,
vorzugsweise jedoch 4 - Figur 3 - Reibräder, die zusammen mit den
Lagerschildern 8 bzw. 8 und 9, in denen die Wellen 4 und 5
beidseitig herausragend in einem Abstand, der größer als ein
Reibraddurchmesser ist, gelagert sind, auf denen auf der den
linearen Reibflächen 30 bis 31A zugewandten Seite des
Lagerschildes 8, oder bei 4 Reibrädern der Lagerschilder 8 und 9,
die Reibräder 2 und 2A oder 2 bis 3A und auf der anderen Seite die
Kettenräder 6 und 7 befestigt sind, die Reibradträgereinheit 10
bilden. Der erfindungsgemäße Reibradantrieb wird vorzugsweise,
weil dort keine weiteren Schutzgehäuse erforderlich sind, im nach
unten offenen, als C-Profil ausgebildetem Unterholm des Tores
- Fig. 5 - eingesetzt. Er kann, mit nur zwei Reibrädern und einem
zusätzlichen Schutzgehäuse versehen, auch in einem U-förmigen
Profil, das seitlich am Unter- oder Oberholm des Tores befestigt
sein kann, eingesetzt werden. Als Reibflächen müssen beim Einsatz
von 2 Reibrädern - Fig. 2 - mindestens 2 sich gegenüberliegende,
parallel oder annähernd parallel zueinander verlaufende,
weitgehend ebene Flächen vorhanden sein. Werden 4 Reibräder
- Fig. 3 - eingesetzt, müssen 2 sich gegenüberliegende
Reibflächenpaare vorhanden sein.Instead of the roller chain drive, a toothed belt,
Flat belt or round belt drive can be used. The
Friction wheel drive according to the invention can both for driving
self-supporting sliding gates, as well as for driving
Sliding gates are used, the weight of which is on rails
running idlers is supported. Of course you can

Attach moving object, generally with the
Rail opening is arranged away from the object. The
friction wheel drive according to the invention has at least 2 - Figure 2 -,
but preferably 4 - Figure 3 - friction wheels, which together with the
Um bei Stromausfall oder sonstigem Versagen des Torantriebes das
Tor von Hand verschieben zu können, hat der erfindungsgemäße
Reibradantrieb eine Notentriegelungsmöglichkeit. Die
Notentriegelung besteht aus der in der ortsfesten Stütze 13
gelagerten Entriegelungswelle 23, auf der unterhalb der
Reibradträgereinheit 10 der Exzenterhebel 24 befestigt ist und
deren zweites Ende sich in einem nur mit einem Schlüssel zu
öffnenden Schaltschrank befindet und mit einem Betätigungshebel
verbunden werden kann und dem im Mittelbereich zwischen den
Reibradlagern an der Reibradträgereinheit 10 angebrachten
Widerlager 21, das sich gegen die ortsfeste Stütze 13 abstützt.
Durch Drehen der Entriegelungswelle 23 wird über den Exzenterhebel
24 die über das Widerlager 21 abgestützte Reibradträgerheit 10
etwas gekippt, wodurch der Kontakt zwischen den Reibrädern 2 bis
3A und den Reibflächen 30 bis 31A unterbrochen wird. Dadurch ist
das Schiebetor von Hand verschiebbar. To do this in the event of a power failure or other failure of the door operator
To move the gate by hand has the invention
