Abstract

This research evaluates transverse keys against various spline connections for torque transfer efficiency. Fine splines demonstrate superior performance overall, while transverse keys offer competitive advantages for narrow hubs and cost-sensitive applications. The findings guide designers in selecting suitable connection types based on torque requirements, manufacturing complexity, and practical constraints.
