1) Aplicaciones de engranajes de doble hélice
Los engranajes de doble hélice son adecuados para requisitos de transmisión de alta potencia, como en grúas, transmisiones marinas 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 de doble hélice pueden proporcionar una mayor eficiencia en comparación con los engranajes helicoidales simples.
