Beschreibung
Zusammenfassung:	The invention discloses a turning gear for a fan shaft, which belongs to the technical field of turning gear, and comprises a mounting assembly, a rotating assembly and a turning assembly, the body assembly comprises a driving part arranged on the supporting frame, a driving chain wheel arranged on the driving part and a driven chain wheel detachably arranged on a fan shaft, a chain is arranged between the driving chain wheel and the driven chain wheel, the driving part drives the driving chain wheel to rotate, and an anti-falling part is arranged on the driven chain wheel; the tensioning assembly comprises a limiting piece installed on the supporting frame in a sliding mode, and the limiting piece is suitable for abutting against the chain. The driven chain wheel is detachably installed on the fan shaft, when the rotating speed of the driven chain wheel is low, the limiting piece can enable the chain to be kept in a tensioning state at the moment, and therefore the driven chain wheel is prevented from loosen
