Title:
PROPELLER SHAFT MANUFACTURING METHOD AND PROPELLER SHAFT
Document Type and Number:
WIPO Patent Application WO/2023/176261
Kind Code:
A1
Abstract:
This propeller shaft (PS1) is configured so that: a weld (13) is formed by welding a first cylinder member (11) and a second cylinder member (12), and the thickness (Tw) of said weld is formed thinner than the thickness (T1) of a first end of a first cylinder section (111) and thinner than the thickness (T1) of a first end of a second cylinder section (121). Consequently, the thickness (Tw) of the weld (13) is reduced, and the weight of the weld (13) can be reduced.
Due to this configuration, unbalanced rotation or yawing of the weld (13) when the propeller shaft (PS1) rotates can be suppressed.
