Document Type and Number:
WIPO Patent Application WO/2024/083252
Kind Code:
A1
Abstract:
A parallel-stage medium-speed shaft system connecting structure for a wind turbine. The parallel-stage medium-speed shaft system connecting structure for a wind turbine comprises a sun shaft (1), a downstream shaft portion and a high-speed gear (4), wherein the high-speed gear (4) is arranged at an outer side of the downstream shaft portion in an axial direction, an axis position of the downstream shaft portion is fixed relative to a wind turbine case (9), and the sun shaft (1) is connected to the high-speed gear (4) by means of a thin-wall flange ring, so as to allow the thin-wall flange ring to absorb floating displacement of the sun shaft (1) by means of elastic deformation.
