Lock device for a powertrain of a wind energy assembly and method for locking the powertrain

摘要

The locking device (10) has a locking bolt (12) that is rotated about longitudinal axis at a predetermined angle. The first flat surface (18) is formed at end portion (14) of the locking bolt. A second flat surface (19) is formed between the locking aperture (25) and the locking profile (28). The locking bolt is aligned during insertion into the locking aperture such that first flat surface lies flat against the second flat surface of the locking aperture. An independent claim is included for method for locking power train of wind power plant.
