A gear system for use in a wind turbine, in particular for a yawing system or for a pitching system. The gear system comprises a drive unit comprising a drive motor (3), a primary pinion (4) connected to an being driven directly by the drive unit and an output gear part, e.g. in the form of a toothed gear ring (2). The gear system further comprises at least one secondary pinion (5) positioned in torque transmitting engagement with the primary pinion (6) and the output gear (2) part. The secondary pinion is positioned in such a manner that the direction of torque transmission between the primary pinion and the secondary pinion and the direction of torque transmission between the secondary pinion and the output gear part are substantially perpendicular to each other. |
