Analysis of Energy Efficiency in Spur Gear Transmissions: Cycloidal Versus Involute Profiles by Joaquim Maria Veciana, Pau Salvadó, Pau Català, Lluïsa Jordi

“…The key novelty of this study is the comparative analysis of involute and cycloidal gear profiles with respect to frictional power losses in the tooth contact, as well as their impact on energy efficiency in spur gear transmissions. The coefficient of friction is approximated using two widely applied analytical lubrication models: the elastohydrodynamic and mixed elastohydrodynamic, both of which provide enough accurate values with a reasonable amount of computation burden in comparison with numerical methods. …”
