Abstract

The invention relates to a shafting structure, a lubrication method thereof and a wind turbine generator set. The shafting structure includes a connecting shaft assembly, bearing assemblies, and lubrication assemblies, wherein the connecting shaft assembly comprises a first sleeving part and a second sleeving part which are mutually arranged in a sleeved mode and provided with a common axis; the bearing assemblies are arranged on the connecting shaft assembly and provided with matching faces in sliding fit with the connecting shaft assembly; and the lubrication assemblies are connected with the bearing assemblies, each lubrication assembly comprises a static pressure jacking system and a dynamic pressure lubricating system, the static pressure jacking systems are used for forming a top pressure separation oil film for separating the connecting shaft assembly and the matching faces between the connecting shaft assembly and the matching faces, and the dynamic pressure lubricating systemsare used for forming a lubricating film for lubricating the connecting shaft assembly and the matching faces between the connecting shaft assembly and the matching faces. According to the shafting structure, the lubrication method thereof and the wind turbine generator set provided by the embodiment, a wheel hub and a generator of the wind turbine generator set can be connected, meanwhile, safe and efficient operation of the wind turbine generator set in the starting or operating process can be ensured, and thus the generation benefits of the wind turbine generator set is ensured.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a shafting structure, a lubrication method and a wind power generating set. Background technique [0002] The principle of wind power generation is to use the wind to drive the blades, so that the hub connected to the blades rotates, and then drives the rotor and stator of the generator connected to the hub to rotate relative to each other to achieve power generation. The connection between the hub and the generator needs to be connected through a shafting structure to better transmit the kinetic energy of the hub to the rotor of the generator. [0003] Due to the unreasonable design of the shafting structure of the wind turbine in the prior art, the wind turbine is easily damaged when it is turned on or during operation, causing the wind turbine to be shut down for repairs, which greatly affects the power generation of the wind turbine. benefit. [0004] Therefore, there is...
