Therefore, after removing the split hollow shaft, by moving the friction sleeve coupling onto the first inner shaft and removing the friction sleeve coupling and the first inner shaft,
The elastic joint can be taken out to the outside through this gap left after removal. Therefore, the elastic joint can be opened extremely easily and quickly.
Furthermore, according to the present invention, the output of the prime mover is divided into two parts and transmitted from the output flange to the first inner shaft and the split hollow shaft, so it is possible to reduce the shaft diameter of the first inner shaft. This has the advantage of reducing the outer diameter and length of the friction sleeve coupling (the length of the coupling needs to be approximately twice the shaft diameter), making the entire shaft system more compact. .
