Abstract
A wind turbine with a rotor, a nacelle and a tower. The nacelle comprises a planetary gear () with a planetary holder (), on which the hub () of the rotor is rigidly secured, and which can be connected to the shaft of an electric generator. The planetary gear () comprises a ring gear () fixedly mounted on an engine frame () in the nacelle or on the member () rigidly connected to said frame. The planetary wheels () of the planetary gear can run around a centrally arranged sun wheel () while engaging the latter. The sun wheel is optionally connected to a parallel gear (). The planetary holder () is rotatably mounted in the ring gear () by means of at least two sets () of planetary twin wheels (). Each set of planetary twin wheels is mounted on a bogie shaft () on the planetary holder. Through an axially rearward collar () projecting beyond the ring gear, the planetary holder () is also rotatably arranged on the curved outer side () of the ring gear () by means of an outer radial-axial-roller bearing (). As a result, a wind turbine is obtained which is suited for generating very strong power and which is very compact and ensures a very advantageous transfer of the power at each planetary wheel.
