Beschreibung
Zusammenfassung:	The invention provides a locking device which is used for locking a bearing arranged on a rotor shaft. The locking device comprises a locking nut, a fixed element and a self-lock assembly, wherein the locking nut is connected with the first end of the rotor shaft via a thread and is used for locking the bearing arranged between the locking nut and a shaft shoulder of the rotator shaft; the fixed element is fixed on the second end of the rotor shaft; the self-lock assembly is rigidly connected between the locking nut and the fixed element, and is used for fixing the locking nut and the fixed element along the circumferential direction of the rotor shaft. According to the locking device disclosed by the invention, the locking nut and the fixed element are respectively arranged at two ends of the rotor shaft, and the self-lock assembly is rigidly connected between the locking nut and the fixed element, so that the locking nut and the fixed element cannot rotate along the circumferential direction of the rotor sh
