Abstract : Various providers of drive shafts, for instance Norca and Napco, offer their products to the Royal Netherlands Army. The steel drive shafts fail early as a result of metal fatigue. Perhaps the Norca product performs slightly better than the Napco. This report offers a summary of shaft features as they were tested or researched: chemical composition, hardness, toughness, microscopic structure. The report concludes that the differences in fatigue life are the result of a mix of these features. The existing shafts cannot be upgraded. There is no simple criterion to distinguish one shaft type from the other one.
