| Zusammenfassung | Within mechanical components friction situations of metallic surfaces can appear. Thereby the ignition sources hot surface and mechanically generated sparks can occur. Previous studies have shown that with the use of stainless steels, incendive hot surfaces can occur even before the conditions for spark formation are achieved. Previous studies have only considered friction situations with continuous friction, which may occur in bearings, seals and couplings in case of an error. In addition to the continuous friction situations, repetitive friction situations can be expected in fans, pumps and agitators in the event of a fault. In this work, the formation of ignition sources by repetitive friction were investigated and compared with the formation of ignition sources due to continuous friction. It is shown how different contact ratios and frequencies influence the temperature development. Furthermore, it was investigated by what factor the power density must be increased to achieve the same temperatures as they occur in continuous friction processes. |
