Electrical Bearing Damage, A Problem in the Nano- and Macro-Range

Schneider, Volker; Behrendt, Cara; Höltje, Pauline; Cornel, Daniel; Becker-Dombrowsky, Florian Michael; Puchtler, Steffen; Gutiérrez Guzmán, Francisco; Ponick, Bernd; Jacobs, Georg; Kirchner, Eckhard (Basel : MDPI, 2022)

Rolling bearings face different damaging effects: Besides mechanical effects, current-induced bearing damage occurs in electrical drive systems. Therefore, it is of increasing interest to understand the differences leading ...
Functionality Investigations of Dry-Lubricated Molybdenum Trioxide Cylindrical Roller Thrust Bearings

Konopka, Dennis; Pape, Florian; Heimes, Norman; Behrens, Bernd-Arno; Möhwald, Kai; Poll, Gerhard (Basel : MDPI, 2022)

In addition to using conventional lubricants, such as oil and grease, rolling bearings can also be used with a dry lubricant. For example, the use of dry lubricant systems is necessary when the application of oils or greases ...
A new approach for the prediction of fatigue life in rolling bearings based on damage accumulation theory considering residual stresses

Hwang, Jae-Il; Poll, Gerhard (Lausanne : Frontiers Media SA, 2022)

Today, the service life calculation of rolling bearings is standardized in ISO 281, based on the theory of Lundberg and Palmgren. In the standard calculation method, material properties such as fatigue limit stress were ...
