This utility model discloses an integrated transition yaw connection system for wind turbines, belonging to the technical field of wind power generation equipment. The system includes a wind turbine tower, a slewing bearing, a short-section cylinder, and a lower platform. The wind turbine tower has a truss-type hollow structure. The short-section cylinder is vertically arranged and its top is welded to the lower platform as a whole. Its bottom is connected to the top of the tower through the slewing bearing. This utility model uses a hierarchical structure of truss tower-slewing bearing-short-section cylinder-platform. It utilizes the short-section cylinder to distribute the nacelle load and compensate for installation errors. Combined with the slewing bearing, it achieves low-friction and stable yaw. This structure effectively solves the problems of heavy self-weight, obvious yaw vibration, complex assembly, and easy wear of connection parts of traditional wind turbine towers. It has the advantages of lightweight, stable yaw, convenient installation, and long service life.
