• Detalle

Un aspecto esencial en el campo de la ingeniería mecánica y de fabricación es todo lo relacionado con la transmisión por engranajes, y más concretamente aquello que es fundamental en su diseño y cálculo.

Este libro ayuda a determinar en una transmisión por engranajes cilíndricos la relación existente entre la potencia a transmitir, la relación de velocidades a establecer, el número de revoluciones ya las dimensiones constructivas. Todo ello teniendo en cuenta el material, su tratamiento  térmico, la calidad de su fabricación y montaje así como las condiciones de funcionamiento.
