1) Aplicaciones de engranajes de doble hélice
El engranaje helicoidal doble es adecuado para requisitos de transmisión de alta potencia, como en grúas,
impulsores marinos o turbinas.
2) Características del engranaje de doble hélice
a) Dos engranajes helicoidales deben estar alineados con precisión, de lo contrario, la fuerza de empuje no se equilibrará correctamente y
la consecuencia será una vibración desfavorable.
b) Los engranajes helicoidales dobles pueden proporcionar una mayor eficiencia en comparación con los engranajes helicoidales simples.
