Description
Lubrication is a key factor concerning performance, operational safety and maintainability of rolling element bearings and plain bearings. However, when the question of an appropriate lubrication method arises, a conflict occurs between acquisition and maintenance costs in the context of the technical requirements. In order to resolve this issue, the use of a ring lubricator can offer a considerable contribution. It is basically characterized by a simple design and offers the requirements for improving the maintainability of bearings. However, in order to leverage this potential and make it applicable, both the ring lubricator itself and the ring lubricator in interaction with the bearing, need to be adjusted and verified.
In this work, system-related test methods for determining harmful influencing factors on the lubricant are presented and applied within studies on a test rig comprising a rolling bearing arrangement equipped with a ring lubricator. Based on these experiments, associated with the results of a 6 000-hour long-term test, insights regarding advantageous design criteria for a ring lubricator are discussed and derived. Looking ahead, the presented concept of a Smart Bearing Unit shows perspectives for adapting a ring lubricator to the requirements of digitalization and a more sustainable use of lubricants.
In dieser Arbeit werden anhand von Prüfstandsversuchen an einer Wälzlagerung mit Ringschmiersystem Analysemethoden vorgestellt, die ausgehend von schädlichen Einflüssen auf den Schmierstoff, die Erfassung systembezogener Einflüsse ermöglichen. Basierend auf den daraus und den in Verbindung mit einem 6 000 stündigen Langzeittest gewonnenen Ergebnissen, werden Kriterien für die vorteilhafte Gestaltung eines Ringschmiersystems diskutiert und abgeleitet. Die Vorstellung des Konzeptes einer Smart Bearing Unit stellt weiteres Potenzial des Ringschmiersystems für einen nachhaltigeren Umgang mit Schmierstoff heraus und skizziert dessen Möglichkeiten im Kontext der Digitalisierung.
