As shown in FIG. 1, a conventional joint structure between a runner and a main shaft includes a runner as a means for joining a runner flange 7 provided at the upper part of the runner 1, that is, near the inner circumference of the runner crown 6, and the main shaft 2. A key 5 is installed on the flange joint surface between the flange 7 and the main shaft flange 2', and the rotational torque of the runner 1 is transmitted to the main shaft 2 with this key 5. In addition, when we assume that a water turbine is currently operating, when a certain output is generated and the runner is rotating, a descending force is generated by the force of the water in the F direction, so this descending force and the runner In order to support the weight of the spindle 1, the runner flange 7 and the main shaft flange 2' are fastened together by bolts 3. If the head of the bolt 3 is rotated while being exposed in water, the water will be stirred in the head of the bolt 3 and a problem will occur, so a bolt cover 4 is installed to cover the head of the bolt 3. .

ボス７′に締結している。 The runner crown 6 is integrally provided with a runner flange 7 on a side corresponding to the tip of the main shaft, and a runner boss 7A that corresponds to the outer peripheral surface 2B of the main shaft 2 and projects in the axial direction of the main shaft 2. runner boss 7
A space is formed between the inner diameter surface 7B of A and the outer circumference surface 2B of the main shaft 2, and the friction joint 8 is fitted into the space.
The inner diameter surface 7B of the runner boss 7A and the outer peripheral surface 2B of the main shaft 2 are adjusted so that even if the runner 1 rotates, the inner diameter surface 7B and the outer peripheral surface 2B do not slide. installed. To adjust the friction joint 8, insert the threaded wedge 8C into the hollow hole 8B of the ring 8A in the direction of the arrow, as shown in Figure 2B.
When inserted into P 1 , the main shaft 2 and the runner 1 are connected by the pressing force when the ring 8A expands in the direction of the arrow P 2 . The runner flange 7 and the main shaft 2 are fastened together by bolts 3 in order to support the descending force F due to the force of water acting on the runner 1 and the own weight of the runner 1. In order to prevent water from entering the friction joint 8, a presser plate 9 is fastened to the boss 7' with bolts 3B.

There is no need to cut the key storage groove as in the case of the above method, and the joining time can be significantly shortened. Also, when the runner 1 generates a certain output and rotates, this rotational torque is applied to the inner diameter surface 7.
B, the torque is transmitted to the main shaft 2 via the outer circumferential surface 2B, and the desired purpose of torque transmission can be achieved.
