Abstract

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.

Description

technical field [0001] The present application relates to the technical field of wind power generators, and in particular to a pitch drive module impeller system, wind power generators and a transportation method. Background technique [0002] The object to be transported is usually restricted in its external dimensions not exceeding a certain standard transport size, for example, the height of the transported object is restricted to be less than a preset standard transport height. [0003] The hub assembly is a relatively large assembly in the wind turbine. In the prior art, a hub assembly includes a hub and a pitch drive system. The pitch drive system generally consists of a plurality of discrete components (such as pitch bearings and drive components, etc.), and the multiple discrete components are arranged on the hub. Since the hub itself has a large external dimension, after arranging multiple scattered components in the pitch drive system on the hub, it is very easy t...
