JOINT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/021667
Kind Code:
A1
Abstract:
The joint device according to the present invention comprises: a first coupling member (24a) in which first teeth (30a) are provided to a disc surface; a second coupling member (24b) in which second teeth (30b) are provided to a disc surface; and a fastening member (24c) that fastens the first coupling member (24a) and the second coupling member (24b) at a center part. A reference surface (31) is parallel to the disc surfaces. A tooth surface angle is an acute angle at a point C on a line of intersection between the reference surface (31) and a meshing teeth surface (26a1) between the first teeth (30a) and the second teeth (30b) in a cross-section perpendicular to the radial direction of the first coupling member (24a), the tooth surface angle being formed by the reference surface (31) and a tangent line (26a2) of the meshing teeth surface (26a1). Tooth surface angles α, β of the first teeth (30a) change along the radial direction of the first coupling member (24a).
