Abstract
Dispositivo en rotores para el control independiente de la variación de paso de cada pala, que consta, al menos, de un eje (4) independiente cinemáticamente del rotor (10), y que porta un actuador (9) por cada pala (2); un disco (6) por cada pala, siendo los discos (6) coaxiales al rotor (10) y disponiendo entre sí y entre el disco (63) más exterior y el rotor (10) de medios de deslizamiento que permiten su movimiento longitudinal relativo pero su solidaridad en el giro; medios para transmitir dicho movimiento longitudinal desde el actuador (9) a su disco (6) correspondiente; un multiplicador de par entre cada disco (6) y su pala (2) correspondiente, de modo que dicho movimiento longitudinal del disco (6) se transforme en movimiento de giro de la pala (2) o la parte de ella previamente prefijada. De aplicación en aerogeneradores.
