Description

Technical Field

[0001] The invention relates to the technical field of wind turbine generator sets, and in particular to an elastically supported vacuum perfusion device for a gear box of a wind turbine generator set. Background Art

[0002] The hydraulic elastic support of the wind power gearbox is a device commonly used in the wind power industry. The hydraulic elastic support of the gearbox is installed on the torque arms at both ends of the gearbox to bear the torsion load of the gearbox. Each wind turbine uses two sets of hydraulic elastic supports, with a total of four hydraulic elastic support nodes, that is, four liquid chambers are formed, which are cross-connected by high-pressure hoses to form two sets of hydraulic auxiliary systems. By injecting antifreeze at a specific pressure, the hydraulic elastic support has high torsional stiffness and low vertical stiffness characteristics. The hydraulic system provides the main stiffness, and the elastic support can absorb the vibration of the gearbox and reduce noise. When the hydraulic elastic support is filled with liquid, if there is air mixed in the liquid chamber of the hydraulic elastic support, it will affect the performance and quality of the product. Although the existing wind turbine gearbox hydraulic elastic support is vacuumed during liquid filling, some air still remains, causing the unit to often have a fault of too low elastic support pressure after operation. And if the hydraulic elastic support valve screw is damaged, it cannot be judged whether the liquid is injected into the hydraulic elastic support rubber body, thus causing quality and safety hazards. For this reason, a vacuum filling device for the wind turbine gearbox elastic support is proposed. Summary of the invention
