Abstract
An arrangement for fixing a housing of a wind turbine gearbox in a nacelle, including a housing-fixing means, a nacelle-fixing means, and at least two spring devices. The spring devices support the housing-fixing means against the nacelle-fixing means in opposite directions along a support axis. The spring devices are arranged on different sides of a plane extending parallel to an axis of rotation of an input shaft of the wind turbine gearbox.
