GONZALEZ-REY, Gonzalo. A procedure for estimating of cylindrical worm gear efficiency. Ingeniería Mecánica [online]. 2013, vol.16, n.2, pp. 100-112. ISSN 1815-5944.

In this study, a general procedure is proposed for the prediction of cylindrical worm gear efficiency taking into account friction losses between worm and wheel gear. The procedure is based in two mathematical models developed with empiric relations and theoretical formulas presented on ISO/TR 14521. Mathematical models are oriented to evaluate the worm gear efficiency with interrelation of gear geometry, manufacturing and working parameters. The validation of procedure was achieved by comparing with values of efficiency for worm gear units referenced by a German gear manufacturer company. Finally, some important recommendations to increase worm gear efficiency by means of rational gear geometry and application parameters are presented.

Palabras clave : efficiency; worm gear; rational design; mathematical model; ISO/TR 14521.
