Description
Bei hydraulischen, mit Ö1 als Druckmedium arbeitenden Kipp-, Hebe- und Preßanlagen bedürfen zwar der Kolben und der Zylinder der COlpumpe keiner zusätzlichen Schmierung, jedoch müssen für die einzelnen Drehteile der Anlage oder für der Anlage benachbarte Drehteile besondere Schmiernippel oder selbsttätig arbeitende Schmiereinrichtungen vorgesehen sein.In the case of hydraulic tilting, lifting, and lifting and press systems, the piston and cylinder of the oil pump do not require any additional Lubrication, however, must be for the individual rotating parts of the system or for the system Adjacent turned parts, special grease nipples or automatic lubrication devices be provided.
Der Erfindung liegt die Aufgabe zugrunde, ohne zusätzliche Hilfsmittel die Schmierung von Schmierstellen bei hydraulischen Kipp-, Hebe- und Preßanlagen vorzunehmen.The invention is based on the object without additional aids the lubrication of lubrication points in hydraulic tilting, lifting and pressing systems to undertake.
Erfindungsgemäß 'wird diese Aufgabe dadurch gelöst, daß man mit dem Pumpkolben während eines Bruchteiles des gesamten Hubes Medium zu Schmierstellen fördert. Eine Kolbenpumpe zur Durchführung des Verfahrens ist derart ausgebildet, daß in den Saug- und Druckraum des Kolbenzylinders in Nähe der Druckbereitschaftsstellung des Kolbens mindestens eine mit Schmierstellen verbindende Leitung einmündet. Diese besitzt zweckmäßigerweise kleineren Querschnitt als die Saug-und Druckleitungen der Pumpe.According to the invention 'this object is achieved in that one with the Pump piston to lubrication points during a fraction of the entire stroke promotes. A piston pump for carrying out the method is designed in such a way that that in the suction and pressure chamber of the piston cylinder in the vicinity of the ready-to-print position of the piston opens at least one line connecting with lubrication points. These expediently has a smaller cross section than the suction and pressure lines the pump.
Die Zeichnung zeigt schematisch eine Ausführungsform einer zur Durchfiihrung des Verfahrens bestimmten Olpumpe einer hydraulischen Kipp-, Hebe- oder Preßanlage zum Teil im Schnitt, zum Teil im Aufriß.The drawing shows schematically an embodiment of an implementation of the process determined oil pump of a hydraulic tilting, lifting or pressing system partly in section, partly in elevation.
Der Kolben i des Pumpenzylinders 2 nimmt in der gezeichneten Lage die untere Totpunktstellung, d. h. die Stellung ein, in der er sich in Pumpbereitschaft befindet. Unmittelbar über den Kolben i mündet in den Druckraum 3 eine Leitung 4 ein, deren wirksamer Querschnitt 5 kleiner ist als der Querschnitt der Druck- und Saugleitungen 6 und 7.The piston i of the pump cylinder 2 takes in the position shown the bottom dead center position, d. H. the position in which he is ready to pump is located. A line 4 opens into the pressure space 3 directly above the piston i a, whose effective cross section 5 is smaller than the cross section of the pressure and Suction lines 6 and 7.
Die Leitung 4 führt zu Schmierstellen der hydraulischen Kipp-, Hebe- oder Preßanlage, also vor allen Dingen zu Drehteilen der Pumpe selbst. Es können aber auch auf diese Weise andere bewegte Teile der Kipp-, Hebe- und Preßanlage mit Schmiermittel versorgt werden. Darüber hinaus lassen sich sogar benachbarte bewegte Teile, die z. B. Bestandteil eines mit Kippeinrichtung ausgerüsteten Lastfahrzeuges sind, mit Schmiermittel versorgen.The line 4 leads to the lubrication points of the hydraulic tilting, lifting or press system, so above all to turned parts of the pump itself. It can but also in this way other moving parts of the tilting, lifting and pressing system Lubricants are supplied. In addition, even neighboring ones can be moved Parts that z. B. Part of a truck equipped with a tipping device are to be supplied with lubricant.
Der Kolben i befindet sich in Pumpbereitschaftsstellung und fördert beim Bewegen in Pfeilrichtung in üblicher Weise das C)1 durch die Druckleitung 7 zur Kipp-, Hebe- oder Preßanlage. Während der ersten Millimeter oder Bruchteile von Millimetern fördert der Kolben i jedoch Öl durch die Leitung 4, so daß die Schmierstellen mit C51 versorgt werden. Sind die ersten Millimeter des Hubes zurückgelegt, so wird durch den Kolben i die Leitung 4, 5 abgeschlossen, und es wird, wie üblich; in die Druckleitung 7 gefördert.The piston i is in the ready-to-pump position and conveys When moving in the direction of the arrow in the usual way, the C) 1 through the pressure line 7 for tilting, lifting or pressing systems. During the first millimeters or fractions of millimeters, however, the piston i conveys oil through the line 4, so that the lubrication points be supplied with C51. If the first millimeters of the stroke have been covered, then the line 4, 5 closed by the piston i, and it is, as usual; in the Pressure line 7 promoted.
Da die zu fördernde, für Schmierzwecke bestimmte Ölmenge bei jedem Hub außerordentlich klein ist, kann die Leitung 4, 5 unmittelbar über den in Totpunktlage befindlichen Kolben i in den Raum 3 einmünden.As the amount of oil to be pumped for lubrication purposes for each Stroke is extremely small, the line 4, 5 can be directly above the dead center located piston i open into space 3.
