1) Descripciones del engranaje de doble hélice
Engranaje de doble hélice: también conocido como engranajes Herringbone,
este es un engranaje con dientes de ambas hélices una a derechas y otra a
izquierdas. La doble hélice equilibra las fuerzas axiales.
Se caracterizan por tener cilíndricos de dientes helicoidales.
Los ejes de los engranajes helicoidales pueden ser paralelos o cruzarse, generalmente a 90º. Para eliminar el empuje axial el dentado puede hacerse doble.
Los engranajes helicoidales tienen una resolución axial y para contrarrestar se utiliza la alternativa de doble helicoidal.
