CA 2671192

A power-split wind power gearbox for transmitting a torque generated by a rotor hub (1) to an output pinion (12) rotating relatively faster thereto for driving an electric generator, wherein at least two planetary steps (10a, 10b) connected in parallel are provided for a gear internal power-split gear multiplication, wherein furthermore the coupling of the rotor hub (1) occurs by means of the connecting ring element (2) on the gearbox input side, the element being supported rotatably by means of a large antifriction bearing (5) on a rotationally fixed gearbox housing (3) and transmitting the power flux in a power-splitting manner to the sun gears (6a, 6b) of the planetary steps (10a, 10b), which are connected in parallel, via cardanic decoupling means configured thereon.

Transmission d'éolienne à couple divisé, pour transmettre un couple de rotation produit par un moyeu de rotor (1) à un pignon de sortie (12) tournant plus vite que ce moyeu et destiné à entraîner une génératrice électrique. Au moins deux étages planétaires (10a, 10b) montés en parallèle sont prévus pour la démultiplication à couple divisé interne à la transmission. De plus, l'accouplement du moyeu de rotor (1) s'effectue au moyen d'un élément annulaire de liaison (2) côté entrée de transmission, qui est monté au moyen d'un palier à roulement de grande taille (5) à rotation sur un carter de transmission (3) solidaire en rotation et qui, via des moyens de désaccouplement à la Cardan configurés sur lui, transmet le flux de force à couple divisé sur les couronnes (6a, 6b) des étages planétaires (10a, 10b) montés en parallèle.
