Abstract
Description
Fertigungseinrichtungen und technische Anlagen werden immer weiter automatisiert und teurer. Mit der heutigen Sensorik kann der Groß teil der Betriebsparameter festgestellt werden, damit ein Ausfall der Anlage nicht vorkommen kann bzw. daß mögliche Schäden im Vor feld bereits feststellbar sind.Manufacturing facilities and technical facilities are constantly expanding automated and more expensive. With today's sensors, the big one can part of the operating parameters are determined so that a failure the system can not occur or that possible damage in the front field can already be determined.
Für die Schmierstoffversorgung von sich relativ zueinander bewegen den Teilen gibt es vielfältige Systeme, die die Schmierstoffzufuhr zu den Gleit- und Wälzflächen überwachen. Eine Überwachung, ob je doch der Schmierstoff die Gleit- und Wälzflächen erreicht hat, und an den zu schmierenden Flächen in ausreichender Menge und in opti maler Verteilung vorliegt, ist bis heute ohne großen technischen Aufwand nicht möglich und wird deshalb nicht oder kaum realisiert. Bei vielen Schmierstoffanwendungen ist es jedoch nötig oder von Vor teil, einen schnellen, optischen Überblick über den Schmierungszu stand der Gleit- und Wälzflächen zu erlangen. Das ist bei fest schmierstoffhaltigen Schmierstoffen bei einiger Übung mit ausreichen der Genauigkeit durchführbar. Im Laufe der technischen Entwicklung wurden und werden aber immer mehr Festschmierstoffe durch öllösliche Additive ersetzt. Bei diesen sowie bei transparenten Schmierstoffen ist eine schnelle, optische Abschätzung des Schmierungszustandes prak tisch unmöglich.For the lubricant supply move relative to each other The parts there are various systems that control the lubricant supply monitor the sliding and rolling surfaces. Monitoring whether ever but the lubricant has reached the sliding and rolling surfaces, and on the surfaces to be lubricated in sufficient quantity and in opti There is no major technical distribution to this day Effort is not possible and is therefore not or hardly realized. For many lubricant applications, however, it is necessary or from the beginning part, a quick, visual overview of the lubrication of the sliding and rolling surfaces. That is fixed lubricants containing lubricants are sufficient for some practice of accuracy feasible. In the course of technical development However, more and more solid lubricants have been and are becoming oil-soluble Additives replaced. With these as well as with transparent lubricants is a quick, visual estimate of the lubrication condition table impossible.
Eine Abhilfe wäre das Einfärben des Schmierstoffes mit Farbstoffen oder die Zugabe von stark deckenden Pigmenten. Da mit abnehmender Rauhtiefe und mit immer höheren Anforderungen an die Genauigkeit auch die Schmier filmstärken abnehmen, müßten diese Beimengungen jedoch in einer Menge sein, daß dies zu schmiertechnischen Problemen führt und sich der Schmier stoffpreis erheblich erhöht. A remedy would be coloring the lubricant with dyes or the addition of highly opaque pigments. As the roughness decreases and with ever increasing demands on accuracy also the lubrication decrease film thicknesses, these additions would have to be in a lot be that this leads to lubrication problems and the lubrication material price increased significantly.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zu schaf den, mit dem es möglich ist, kostengünstig und direkt an der Ein satzstelle das Vorhandensein, die Menge, d. h. die Schichtdicke, und den Zustand des Schmierfilmes zwischen sich relativ zueinander bewegenden Teilen zu prüfen. The object of the present invention is to create a method the one with which it is possible, inexpensively and directly at the one the existence, the quantity, d. H. the layer thickness, and the state of the lubricating film between them relative to each other to check moving parts.
Die Lösung der Aufgabe besteht nach der vorliegenden Erfindung darin, daß dem Schmierstoff geeignete Mittel zugegeben werden, die elektromagnetische Wellen oder Korpuskularstrahlung absorbieren, re flektieren oder emittieren und daß mittels eines Empfängers die ent sprechende Strahlung oder ihre Veränderung festgestellt wird. Wenn die dem Schmierstoff zugesetzten Mittel nicht selbst strahlen, werden nach einem weiteren Merkmal der Erfindung, von einem Sender elektromagnetische Wellen oder Korpuskularstrahlung einer bestimmten, diskreten Energieverteilung auf den in geeigneter Weise präparierten Schmierstoff ausgesendet.The object is achieved according to the present invention in that suitable agents are added to the lubricant, which absorb electromagnetic waves or corpuscular radiation, right inflect or emit and that the ent speaking radiation or its change is detected. If the lubricant added does not radiate itself, are according to a further feature of the invention, from a transmitter electromagnetic waves or corpuscular radiation of a certain discrete energy distribution on the appropriately prepared Lubricant sent out.
Als geeignetes Mittel zur Durchführung des erfindungsgemäßen Verfahrens wird nach einem weiteren Merkmal der Erfindung Tinopal CBS-X genannt. Daneben sind selbstverständlich auch andere Zusatzstoffe mit ähnlichen Eigenschaften, wie z. B. Uvitex OB oder dotiertes Zinksulfid Kadmium sulfid, Kalziumwolframat geeignet.As a suitable means for carrying out the method according to the invention is called Tinopal CBS-X according to a further feature of the invention. In addition, there are of course other additives with similar ones Properties such as B. Uvitex OB or doped zinc sulfide cadmium sulfide, calcium tungstate suitable.
Insbesondere zur Prüfung des Zustandes von im Schmierstoff enthaltenen Additiven ergeben folgende Zusatzstoffe beste Ergebnisse: Oxidations inhibitoren auf der Basis sterisch gehinderter Phenole und Amine. Hinsichtlich der Art der zu verwendenden Strahlung bestehen im Prin zip keine Einschränkungen. Grundsätzlich sollte die Wellenlänge der Strahlung nicht zu gering sein, damit keine Schädigung des Schmierstoffes erfolgt, bzw. die Schädigung in einem vertretbaren Umfang bleibt. Als geeignete Strahlung kann nach einem weiteren Merkmal der Erfindung eine UV-Strahlung zur Anwendung gelangen.Especially to check the condition of the lubricant Additives give the following additives best results: Oxidations inhibitors based on sterically hindered phenols and amines. Regarding the type of radiation to be used, the Prin zip no restrictions. Basically, the wavelength of the Radiation should not be too low, so that no damage to the lubricant or the damage remains to a reasonable extent. According to a further feature of the invention, suitable radiation can be UV radiation is used.
Mit der vorliegenden Erfindung ist es möglich, kostengünstig direkt das Vorhandensein eines Schmierfilmes zu überprüfen und seinen Zustand abzuschätzen. With the present invention it is possible to inexpensively direct check the presence of a lubricating film and its condition to estimate.
