WIND POWER GENERATION DEVICE

Title:

WIND POWER GENERATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/141940

Kind Code:

A1

Abstract:

According to the present invention, a one-way clutch for a wind power generation device connects an input rotation body and an output rotation body so as to allow integral rotation in a state in which the rotational speed of the input rotation body is greater than the rotational speed of the output rotation body, and severs the connection between the input rotation body and the output rotation body in a state in which the rotational speed of the input rotation body falls below the rotational speed of the output rotation body. The input rotation body and the output rotation body are allowed to move relative to each other in an axial direction, and the maximum allowable amount thereof is set to be greater than the amount of fluctuation in the axial gap between an input shaft and an output shaft, brought about by a change in the state.
