PURPOSE:To improve the strength, by forming the base of a wing in a dovetail, forming a groove at the periphery of a disk to fit to the base, and gearing and fixing the base of the wing to the groove with a heatproof adhesive. CONSTITUTION:This ceramic impeller 11 consists of a wing 12, a disk 13, and a rotary shaft 14. The base 12a of the wing 12 is formed in a dovetail, and at the periphery of the disk 13, a groove 13a is formed to gear with the base 12a. The base 12a is geared with the groove 13a of the disk 13, and fixed through a heatproof adhesive 15. Therefore, an excellent strength can be obtained against a tensil force from a centrifugal force. |
