Problems solved by technology
However, a disadvantage associated with such solutions is that the belts, which are worn during use, are expected to require several complex and time-consuming replacements during the total lifetime of the wind turbine generator
Also, it can be difficult to monitor when the time has come to replace the belt, so it may be necessary for safety reasons to replace it more often than is actually necessary

Embodiment Construction
[0020] A conventional wind turbine is disclosed in FIG. 1 . Wind turbine 10 includes a tower 12 , a nacelle 14 disposed at a top end of tower 12 , and includes a rotor 16 operatively coupled to a generator 18 housed within nacelle 14 . In addition to generator 18 , nacelle 14 houses the various components needed to convert wind energy into electrical energy and to operate, control, and optimize the performance of wind turbine 10 . Tower 12 supports loads provided by nacelle 14 , rotor 16 , generator 18 , and other components of wind turbine 10 housed within nacelle 14 . The tower 12 of the wind turbine 10 also operates to elevate the nacelle 14 and rotor 16 to a height above ground or sea level, where fast moving airflows with low turbulence are typically found.
[0021] The rotor 16 of the wind turbine 10, shown as a horizontal axis wind turbine, acts as the prime mover of the electromechanical system. Wind above a minimum level will activate the rotor 16 and cause rotation...

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.
Description
technical field [0001] The invention relates to a transmission for a wind turbine generator. The invention further relates to a method for servicing such a transmission and a wind turbine generator comprising such a transmission. Background technique [0002] Wind turbines typically include a rotor with large blades driven by the wind. The blades convert the kinetic energy of the wind into rotational mechanical energy. The mechanical energy is usually transferred via a transmission to a generator, which then converts the energy into electricity. Typically, it is necessary to increase the rotational speed of the rotor to the speed required by the generator. In these cases, the transmission includes a gearbox that converts the low-speed, high-torque input of the rotor to the low-torque, high-speed output of the generator. [0003] Most wind turbines hold the transmission and generator in a nacelle on top of the wind turbine tower. An alternative is to transmit the torque ...
