Test rig for misagligned spline couplings
MisalignmentSpline couplingsWear
Introduction
Test rig to investigate wear and endurance of spline couplings working in misaligned conditions.

Technical features
The peculiarity of this test rig is to allow angular misalignments between hub and shaft in order to investigate the behavior of spline couplings in real working conditions, to investigate fretting wear phenomena. The test rig design is compact and cost effective thanks to the mechanical power re-circulating construction scheme. Tests can be performed with lubricant (oil or grease) on in dry conditions.
