Abstract

In the testing of the presence, amt. and condition of a lubricant film between moving parts, the novelty is that suitable agents (I) are added to the lubricant so that electro-magnetic agents (I) are added to the lubricant so that electro-magnetic waves or corpuscular radiation, e.g. electrons, is absorbed, emitted or reflected and any changes of radiation are measured by a suitable receiver. Lubricant for carrying out the above process is also claimed and comprises additives based on simple or condensed aromatic ring systems, or oxidation inhibitors based on sterically hindered phenols and amines. Specifically, electromagnetic waves of a certain wavelength are applied on to the lubricant prepared with suitable agents. Corpuscular radiation of a certain discrete energy distribution are applied to the lubricant prepared in the suitable way. (I) is pref. Tinopal CBS-X or Uritex OB, or doped ZnS, CdS, or Ca-tungstenate. UV-radiation is pref. used to irradiate the lubricant. USE/ADVANTAGE - Process can be used in the lubricant suoply of moving parts, esp. in lubrication of open-lying carriageways, gearboxes, cogs, chain drives and other parts of machinery.

Description

Stand der TechnikState of the art

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 ErfindungObject 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.
