Document Type and Number:
WIPO Patent Application WO/2023/218714
Kind Code:
A1
Abstract:
A power transmission shaft of the present disclosure connects two rotating devices with each other, and is capable of transmitting power from one device to the other device. The power transmission shaft comprises an FRP shaft extending around an axis, and a pair of metal flanges connected to the FRP shaft in an axial direction. The FRP shaft has a first cylindrical part, and a pair of second cylindrical parts integrally connected to the first cylindrical part. The second cylindrical parts each have a base part connected to the first cylindrical part, and a plurality of protruding parts that protrude from the base part in the axial direction, the plurality of protruding parts being disposed spaced apart from each other at equal intervals in a circumferential direction and thereby forming, together with the base part, a plurality of keyways extending in the axial direction. The metal flanges each have a connection part that is connected rotatably to a device, and a plurality of keys that protrude from the connection part in the axial direction and individually fit into the keyways. The thickness of the protruding parts in the circumferential direction is larger than the thickness of the keys in the circumferential direction.
