Abstract

The gear unit has a drive, preferably an electric motor, energized by an accumulator of rotational direction and torque, is attached at the drive shaft (1). A high pressure piston press is firmly connected to the gear unit. The torque of the electric motor is so strongly reduced by a spur gear (4) through a worm gear (3), which is firmly connected with the drive shaft that the amount of the stroke per minute of the delivery piston (7) is reliably delivered depending on consistency of the medium, particularly grease, which is to be delivered.

Description

Die planmässige Versorgung fettgeschmierter Lager an Maschinen in nicht ortsgebundenen Betrieben z.B. der Land- und Bauwirtschaft ist häufig auch der wechselnden Einsatzstellen und unterschiedlichen Betriebszeiten wegen nicht möglich. Lagerausfälle oder auch z.B. abgebrannte Mähdrescher sind bekannte Folgen.The according to plan Supply of grease-lubricated bearings to machines in non-stationary Operated e.g. The agricultural and construction industry is often also the changing employment agencies and different operating times because of not possible. Bearing failures or also e.g. spent combine harvester are known consequences.

Die Schmierung mit den bekannten handbetriebenen Fettpressen ist zeitaufwendig und je nach Pressentyp auch schmutzig und deshalb bei den Maschinenführern unbeliebt. Mangels Netzstrom- bzw. Druckluftversorgung können Pressen mit Fremdenergiebetrieb nicht eingesetzt werden, mit leistungsfähigen Akkus betriebene Fettpressen sind auf dem Markt nicht verfügbar oder sehr teuer. Demgegenüber stehen akkubetriebene Bohrschrauber in vielen Leistungsstufen preisgünstig zur Verfügung und sind fast überall vorhanden.The Lubrication with the well-known hand-operated grease guns is time consuming and depending on the press type also dirty and therefore unpopular with the machine operators. In the absence of mains or compressed air supply, presses can be operated by external energy companies can not be used with powerful battery powered grease guns are not available in the market or very expensive. In contrast, battery-powered drill drivers are inexpensive in many performance levels disposal and are almost everywhere available.

Das im Patentanspruch 1 beschriebene Getriebe für Hochdruck-Schmierpresse ist so konzipiert, dass es zusammen mit einem beliebigen Akku-Bohrschrauber allein durch Anschrauben der Antriebswelle 1 an dessen Bohrfutter ohne jeden Eingriff in das elektrische bzw. elektronische System und ohne Wechsel der Drehrichtung den Kolben der Fettpresse in der jeweils erforderlichen Hubzahl/min bewegen und Schmierfett unterschiedlicher Konsistenzklassen mit dem jeweils erforderlichen Druck fördern kann.The transmission described in claim 1 for high-pressure lubricating press is designed so that it together with any cordless drill alone by screwing the drive shaft 1 at the drill chuck without any intervention in the electrical or electronic system and without changing the direction of rotation can move the piston of the grease gun in the required number of strokes / min and lubricating grease different consistency classes with the respective required pressure.

Dazu wird das Drehmoment des akkubetriebenen Bohrschraubers über die Excenterwelle 2 auf ein Schneckenrad 3 und ein Stirnrad 4 übertragen. Dabei wird die Drehzahl des Stirnrades 4 reduziert und zugleich das Drehmoment – abzüglich der Reibungsverluste des Schneckengetriebes – erhöht.For this purpose, the torque of the battery-powered drill screw on the eccentric shaft 2 on a worm wheel 3 and a spur gear 4 transfer. At the same time, the speed of the spur gear becomes 4 reduces and at the same time the torque - minus the friction losses of the worm gear - increased.

Die mit dem Stirnrad 4 fest verbundene Excenterwelle 2 trägt eine ebenfalls fest mit der Excenterwelle 2 verbundene Excenterscheibe 5 welche über einen Rollenstössel 6 den Drucktakt der Schmierpresse betreibt. Der Rollenstössel 6 ist auf der Seite der – dem bekannten Stand der Technik entsprechenden – Schmierpresse als Förderkolben 7 ausgebildet. Zur Vermeidung von Verdrehungen und damit u.U. verbundenen Beschädigungen der Kolbendichtungen wird die Rolle 8 des Rollenstössels 6 in einer Nut 9 am Umfang der Excenterscheibe 5 geführt.The with the spur gear 4 firmly connected eccentric shaft 2 also carries one with the eccentric shaft 2 connected eccentric disc 5 which via a roller plunger 6 operates the pressure stroke of the lubrication press. The roller pusher 6 is on the side of - according to the known state of the art - lubricating press as a delivery piston 7 educated. To avoid twisting and thus possibly associated damage to the piston seals becomes the role 8th of the roller pusher 6 in a groove 9 on the circumference of the eccentric disc 5 guided.

Die Rückbewegung des Förderkolbens 7 benötigt gegenüber dem Drucktakt wesentlich geringere Kräfte und wird erfindungsgemäss durch eine den Förderkolben 7 umwindende Druckfeder 10 zwischen Pressenzylinder 11 und Stösselkopf 12 bewirkt.The return movement of the delivery piston 7 requires compared to the pressure stroke much lower forces and according to the invention by a delivery piston 7 winding compression spring 10 between press cylinders 11 and plunger head 12 causes.

Ein – in der Zeichnung nicht dargestelltes – zweiteiliges Gehäuse kann sowohl die Lager der Antriebswelle 1 mit Schneckenrad 3, und die der Excenterwelle 2 mit Stirnrad 4 und Excenterscheibe 5 sowie den Pressenzylinder 11 aufnehmen.A - not shown in the drawing - two-piece housing can both the bearings of the drive shaft 1 with worm wheel 3 , and the eccentric shaft 2 with spur gear 4 and eccentric disc 5 and the press cylinder 11 take up.

Die Erfindung erlaubt mit ihren wenigen Teilen die wirtschaftlich günstige Herstellung eines Gerätes welches der Betriebssicherheit durch Erleichterung der notwendigen Maschinenschmierung dient.The Invention allows with their few parts the economically favorable production a device which of operational safety by facilitating the necessary Machine lubrication is used.
