The embodiment of the invention provides a variable-
pitch driving module, an
impeller system, a wind generating set and a transportation method. The variable-
pitch driving module comprises a supporting plate, a variable-
pitch bearing, a variable-
pitch control cabinet and at least one driving
assembly, wherein the supporting plate is fixedly connected to a wheel hub; one end surface of a bearing outer ring of the variable-
pitch bearing is fixedly connected to the supporting plate, and the end surface, away from the supporting plate, of a bearing inner ring of the variable-
pitch bearing is used for being fixedly connected to blades; supports of the driving assemblies are fixedly connected to the supporting plate, and the
power output ends of the driving assemblies are in transmission connection with the bearing inner ring through a gear meshing mode; and the variable-
pitch control cabinet is fixedly connected to the supporting plate, and the variable-
pitch control cabinet is further electrically connected to the driving assemblies. The variable-pitch driving module can be separately transported from the wheel hub, due to the fact that the wheel hub and the variable-pitch driving module are smaller than a hub
assembly, the appearance size of the wheel hub and the appearance size of the variable-pitch driving module are easier to meet the limit conditions of the standard transportation size, and therefore the transportation difficulty is reduced.
