Title:

SUPPORT APPARATUS FOR SHAFT SYSTEM, AND WIND TURBINE

Document Type and Number:

WIPO Patent Application WO/2023/045294

Kind Code:

A1

Abstract:

A support apparatus for a shaft system. The shaft system comprises a first shaft (1), a second shaft (2), and a bearing (3) arranged between the first shaft (1) and the second shaft (2); the first shaft (1) is sleeved at an outer peripheral side of the second shaft (2) and is able to rotate relative to the second shaft (2) by means of the bearing (3). The support apparatus is used for arranging at a first end in an axial direction of the shaft system, and the support apparatus comprises: shaft end support members (8, 15), at least a portion of the shaft end support members (8, 15) being rotatably supported in an axial direction at an outer side of a shaft end face of a first end of the second shaft (2); and connection assemblies (17, 14), where the connection assemblies (17, 14) in the axial direction of the shaft system are used for being connected between a first end of the first shaft (1) and the shaft end support members (8, 15). Further disclosed is a wind turbine. The present support apparatus may enable a bearing of a shaft system to essentially not bear a load or reduce an axial load borne, and the service life of the bearing is prolonged.
