Abstract:

This research was motivated by the absence of a means to design a straight spline coupling in a reliable way. It is shown that the strain and pressure distribution in a spline coupling are not uniform. To predict these phenomena, an assistance tool would be of key interest. In this paper, a simplified finite element model has been made of a spline coupling to build a dimensioning tool for such couplings. This tool can give information about strain on the outside diameter of the sleeve and axial torque distribution. This study is based on an experimentally validated three-dimensional finite element model of the coupling under torsional load. Different sleeve sizes and loading methods are tested to highlight their effects on the axial torque distribution
