Abstract

PURPOSE: To prevent resonance of vibration mode by connecting all moving vanes with each other to form a ring and using prominent connecting points at a moving- vane-connected point to device them into many groups.
CONSTITUTION: For higher rigidity and lower vibration, the near ends of many moving vanes radially fixed on a rotor disc 2 are connected with each other by using a connecting element 3 to form a ring and they are devided into many groups by prominent connecting points 4. Every group between each point 4 includes number n1, n2, or n3 moving vanes 1 less than 10. The connecting point 4 will allow axial vibration displacement not tangential displacement. The connecting point 4 constitutes that a pin 5 joins each half hand of the connecting element 3a, 3b which is fixed on the moving vane 1a, 1b.
