Unser komplettes Seminarprogramm für 2023 ist jetzt online!
Wir bieten wie gewohnt “Basics of Bearing Technology”, “Application Engineering,” “Bearing Supplier Development”, und “Failure Analysis” an.
Herbst 2023: September – Dezember
Dieses Seminar vermittelt Basiswissen u. a. zur Gestaltung von Lagerungen, Schmierstoffen und Lebensdauerberechnung. Dabei werden insbesondere die folgenden Themen behandelt:
Dieses neue zwei-teilige Seminar baut auf die Basics auf und untersucht Berechnungen von verschiedenen Anwendungsbeispielen..
Die weltweite Beschaffung von Wälzlagern bietet viele Möglichkeiten zur Optimierung der Lieferkette, gleichzeitig ist jede Freigabe eines neuen Lieferanten prinzipiell mit einem Qualitätsrisiko verbunden.
Daher werden in diesem Seminar die folgenden Themen behandelt:
Das Erkennen und Verstehen von Schadensursachen ist erforderlich, um zielgerichtet die notwendigen Gegenmaßnahmen einzuleiten. Daher wird in diesem eintägigen Seminar anhand von praktischen Beispielen gezeigt, wie Schadensmerkmale erkannt werden und welche Schlussfolgerungen daraus zu ziehen sind. Die Schwerpunkte sind dabei vor allem:
"Bearings in planetary gears, hydraulic pumps and others are frequently exposed to conditions where elastic deformations intheir surrounding parts lead to significant misalignment oftherings towards each other. Such misalignment results in local pressure peaks and an associatedreduction of bearing life. Proper raceway crowning lessens these effects and is therefore a highly relevant consideration during supplier approval."
"The influence of local stresses can be considered during the design process but also needs to be taken into account during testing if bearing performance is to be verified on a test rig. Here, the acceleration of test runs can complicate the situation. Typically, test loads are higher than application loads because years of service life must be represented by weeks on a test bench. When investigating the effect of misalignment, the chosen testing conditions must lead to non-uniform stress distributions similar to those expected in the application."
"When testing, the degree of misalignment can be controlled with the use of customized fixtures. However, it is always important to verify that the test conditions adequately mimic the application. The FVA Workbench is a powerful tool that can calculate local stresses bothfor the application and the test case.This article shall show a general approach to testing for applications where significant misalignment in the bearings is expected."
"Bearings are a globally sourced commodity. As such, quality control of regular deliveries as well as the evaluation of new suppliers is highly important. Bearing trading companies who work independently from specific brands constantly need to optimize their supplier base, which means reducing costs without jeopardizing the quality. Quality control is even more critical when selling bearings under the house brand. Additionally, customers need to be convinced that the alternative product will meet the requirements of their applications."
„When scientific research aims to break down the existing limits of machine elements, the associated equipment must meet the highest demands. Professor Kirchner and his team at the Technical University of Darmstadt (TUD) intend to use the electrical properties of rolling contact bearings for various purposes, including as sensors. This endeavor poses two particular challenges: measuring the bearing’s impedance at high frequency and understanding how the associated high frequency electric currents might impact bearing life. For this purpose, Elgeti Engineering GmbH built a special test rig which is capable of applying and measuring high frequency electric currents and voltages on all four of its stations.
The first research results were announced at the BearingWorld International Conference in October 2020. We are very pleased to share the associated article and are proud to support the highest level of academic research. Many thanks to Georg Martin, Tobias Schirra, and Prof. Dr. Eckhard Kirchner for the excellent collaboration and good luck with the further research!“
„When selecting a bearing supplier for industrial machinery, one typically needs more than just a bearing. In fact, what one really needs is a three-tiered service consisting of application engineering, the bearing itself, and preventative maintenance services such as diagnostics and condition monitoring. Operators of industrial plants such as steel mills and tire factories in particular rely on these services when working with the premium manufacturers.They appreciate their advice before buying and know they are in good hands if a problem were to arise.In collaboration with competent engineering companies, however, independent bearing distributers can meet or even outperform this level of customer service. The strength of bearing distributers is finding cost-efficient and reliable solutions while after-sales-services like preventive maintenance can generate further profitable business.“
Es gibt verschiedene Gründe Wälzlager zu prüfen, wie zum Beispiel die Erstfreigabe eines Lieferanten, die regelmäßige Qualitätskontrolle, oder eine schnelle Abnahmeprüfung. Das "warum" ist der Anfang, aber das "wie" ist auch eine relevante Frage. Es ist wichtig zu verstehen, welche Teststrategien es gibt, welche für die Situation angepasst sind, sowie die technischen Fähigkeiten der Prüfmittel. Dieser Artikel verschafft einen Überblick über wann eine Prüfung angemessen ist, welche Methoden es gibt, und die Unterschiede zwischen den verschiedenen Prüfständen die es auf dem Markt gibt.
