Item Open Access Einfluss supergefinishter Dichtungsgegenlaufflächen auf die Funktion von Radial-Wellendichtungen(2016) Schulz, Markus; Bauer, Frank; Haas, WernerItem Open Access Influence of protection lips on the frictional torque of rotary shaft seals(2024) Olbrich, Christoph; Feldmeth, Simon; Bauer, FrankRotary shaft seals are used to seal rotating machine parts. In most cases one single sealing lip (main lip) contacts the shaft and separates the fluid on one side from the environment on the other side. To prevent the entry of other fluids and or particles, seals with additional protection lips are used (two lips), especially in heavily contaminated environments. When the protection lip contacts the shaft, a vacuum can form between the main lip and the protection lip, leading to increased contact pressure and friction. The increased frictional torque generates more heat and leads to overheating in the contact area between the lip and the shaft. Test runs conducted on a friction torque test bench with various seal configurations confirm that the two lips influence each other. Higher frictional torques and contact temperatures occur, when the volume between the lips isn't vented. This shows the importance of venting.Item Open Access Moderne visuelle Untersuchungsmethoden für die Verschleißanalyse am Beispiel Radial-Wellendichtring(2018) Baumann, Matthias; Bauer, FrankItem Open Access Messung, Analyse und Bewertung von Dichtungsgegenlaufflächen für das Tribo-System Radial-Wellendichtung(2014) Baumann, Matthias; Bauer, Frank; Haas, WernerItem Open Access Empirische Modellierung der Drall-induzierten Fluidförderwirkung von Dichtungsgegenlaufflächen - Sind Grenzwerte möglich?(2016) Baumann, Matthias; Bauer, Frank; Haas, WernerItem Open Access Einflüsse praxisrelevanter Systemparameter auf das Förderverhalten von Radial-Wellendichtungen(2018) Bekgulyan, Sumbat; Simon, Feldmeth; Bauer, FrankItem Open Access PTFE lip-seals with bi-directional sealing aids(2012) Gölz, Jan; Goujavin, Witalij; Bauer, Frank; Haas, WernerItem Open Access Mechanismen im Dichtspalt fettabdichtender Radial-Wellendichtungen(2014) Sommer, Max; Bauer, Frank; Haas, WernerItem Open Access Bidirectional PTFE lip seals - superior to elastomeric seals?(2014) Gölz, Jan; Bauer, Frank; Haas, WernerItem Open Access Erweiterung der Einsatzgrenzen von PTFE-Manschettendichtungen mit Spiralrille(2006) Bauer, Frank; Haas, Werner
