TRANSMISSION FOR A WIND TURBINE GENERATOR

摘要

The present invention relates to a rope-driven transmission for a wind turbine. The transmission comprises an input rotary member for being operatively connected to a rotor of a wind turbine and in rotational connection with at least one secondary shaft which is arranged in parallel with the rotational axis of said input rotary member, wherein said secondary shaft is adapted for operative connection with an output member of at least one electrical generator, wherein said rotational connection between said input rotary member and said at least one secondary shaft is provided by a rope, the course of said rope defining a rope path, and wherein said rope path includes a plurality of turns around said input rotary member and said secondary shaft. The transmission facilitates an easy monitoring and maintenance of the transmission. The invention further relates to a method of maintaining the transmission by replacing the rope. The invention further relates to a wind turbine generator comprising the transmission.
