Research Project: Load Collectives Rotary Shaft Seals

Institute of Machine Components (IMA)

Generation of load collectives for testing rotary shaft seals

To date, no simulation or lifetime prediction of elastomer rotary shaft seals is possible. Each seal must therefore be tested in suitable, application-related test runs. The FVA project series 696 deals in several individual projects with the effects of thermal and dynamic load on the sealing system rotary shaft seal. The development of thermal damage and abrasive wear under progressive loading is documented with extensive test series. The aim of the project series is to enable a systematic generation and evaluation of test cycles for rotary shaft seals. This will make it possible to derive individual, representative load collectives for rotary shaft seals from real loads. New sealing systems can be selected and tested for specific applications. In product use, it will be possible to identify and specifically avoid harmful operating conditions. Maintenance intervals can be extended and downtimes can be shortened.
