Abstract
PURPOSE: To moderate an external force exerted on the cover due to untwise (recovery of twist) constraining force of a rotary blade so as to improve the vibration damping effect by means of a turbine rotary blade coupling device capable of constraining simultaneously both the vibration mode and the twisting mode either in blade row direction or in the normal direction thereto.
CONSTITUTION: Each of adjacent rotary blades 1, 2 is provided with the eaves 8, 9 respectively in the direction opposite to each other on both front and rear edges 1a, 1b and 2a, 2b of each top end with through holes 10, 11 provided on each of eaves 8, 9. Further, a rotary blade interlocking piece 12 of an approximate parallelogram form is set between the tips of these rotary blades 1, 2. Cylindrical pins 13, 14 are integrated with the rotary blade interlocking piece 12 on its top face at the symmetric positions on its diagonal, and fitted in the above mentioned through holes 10, 11 being inserted from lower side. And also contact faces 15, 16 are projecting to a certain extent from the side faces of interlocking piece 12, and the untwist between the blades 1, 2 can be constrained, if the interlocking piece 12 is assembled while setting these contact faces 15, 16 to keep contact with the rotary blades 1, 2.
