Title:
WIND MOTOR PARALLEL-STAGE INTERMEDIATE-SPEED SHAFT SYSTEM CONNECTING STRUCTURE, AND SHAFT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/083245
Kind Code:
A1
Abstract:
A wind motor parallel-stage intermediate-speed shaft system connecting structure, wherein a sun shaft and a hollow shaft are connected together by means of rigid connection. The bearing of the hollow shaft is arranged on a box body on one side of a generator. Floating displacement of the sun shaft in the operation process of the generator is absorbed by the bearing. Because an interference spline is used to achieve the rigid connection between the sun shaft and the hollow shaft, lubrication and cooling do not need to be provided for the spline, and the structure has low manufacturing costs and a simple structure. Further provided in the invention is a wind motor parallel-stage medium-speed shaft system, having the advantages of simple structure and low maintenance costs.
