Abstract
Spline couplings are mechanical devices commonly used to join two shafts. Accordingly to the type of spline (straight teeth, crowned teeth, etc ) and gap between the teeth, joined shafts may have certain positioning errors, as misalignments or inclinations. Spline couplings utilised on aerospace applications need more accurate dimensioning in order to reduce the weight and to control failure mechanisms (as an example like fretting fatigue), then an accurate study about loads distribution on the tooth surface is needed, in particular pressure distribution. Many theoretical studies about pressure distribution are available in literature [1], [2], on the other hand, experimental analysis are very rare. The aim of this work is to verify by means of an experimental set-up the theoretical results available in literature [1], [2], [5] about pressure distribution on spline couplings.
