It is suitable for transmission occasions where the angle B between the two axes on the same plane of the connection space is less than 45°, and the nominal torque transmitted is 11.2-1120N.m.
The maximum angle between the axes of each section is 45.
The finished hole tolerance is H7, and keyways, hexagonal holes and square holes can be opened according to requirements.
The angle between the two axes is allowed to change within a limited range according to work needs.
