Title
(EN) WIND TURBINE WITH MODULAR MAIN SHAFT FASTENING SYSTEM AND ROTOR LOCKING DISC
(FR) ÉOLIENNE AVEC SYSTÈME DE FIXATION D'ARBRE PRINCIPAL MODULAIRE ET DISQUE DE VERROUILLAGE DE ROTOR
Abstract
(EN)
A wind turbine (10) includes a first connecting structure (36) associated with the main shaft (34) fixed to a second connecting structure (40) of a rotor hub (22). A plurality of blades (24) is coupled to the rotor hub (22). A rotor locking disc (32) is carried on the main shaft (34). The rotor locking disc (32) has a peripheral region and a plurality of rotor locking elements (50) in the peripheral region for receiving one or more rotor locking pins (30). The first connecting structure (36) includes at least first and second sets of fastener holes (38a, 38b, 38b'). The first set of fastener holes (38a) is located at a position radially inward of the rotor locking elements (50) and the second set of fastener holes (38b, 38b') is located between adjacent rotor locking elements (50). The first and/or second set of fastener holes (38a, 38b, 38b') are used to receive fasteners (39a, 39b) to secure the main shaft (34) to the rotor hub (22).
(FR)
L'invention concerne une éolienne (10) qui comprend une première structure de liaison (36) associée à l'arbre principal (34) fixée à une seconde structure de liaison (40) d'un moyeu de rotor (22). Une pluralité de pales (24) est couplée au moyeu de rotor (22). Un disque de verrouillage de rotor (32) est porté sur l'arbre principal (34). Le disque de verrouillage de rotor (32) comporte une région périphérique et une pluralité d'éléments de verrouillage de rotor (50) dans la région périphérique pour recevoir une ou plusieurs broches de verrouillage de rotor (30). La première structure de liaison (36) comprend au moins des premier et second ensembles de trous de fixation (38a, 38b, 38b'). Le premier ensemble de trous de fixation (38a) est positionné radialement vers l'intérieur des éléments de verrouillage de rotor (50) et le second ensemble de trous de fixation (38b, 38b') est situé entre des éléments de verrouillage de rotor adjacents (50). Le premier et/ou le second ensemble de trous de fixation (38a, 38b, 38b') sont utilisés pour recevoir des éléments de fixation (39a, 39b) afin de fixer l'arbre principal (34) au moyeu de rotor (22).
