Abstract

PURPOSE: To securely receive the torque applied to a coupling pin and easily assemble and disassemble the coupling pin, by providing double anti-rotation plates for the coupling pin of a coupling mechanism of hydraulic machine.
CONSTITUTION: A guide ring 14 for opening/closing a guide vane 16 is driven by a cylinder 3 through a piston rod 5 and a connecting link 8. Since the guide ring 14 performs an arc-shaped motion, a turning force is applied to the coupling pin 7 because of the frictional force between the sliding surfaces of the coupling pin 7 and a bushing 9. an anti-rotation plate 11 is welded to the connecting link. Another anti-rotation plate 10 is installed bweteen the former anti-rotation plate 11 and a notch of the coupling pin 7 and clamped to the connecting link by a bolt 12. The turning force of the coupling pin 7 is surely received by the anti-rotation plate 11. The coupling pin 7 can be removed by removing only the anti-rotation plate 10
