To explain the drawing, which is an example of O, which is a completely submerged disk of lt piece (11
The circumferential edge of the disk (2) radially caulked or implanted by other methods to constitute the turbo fan is curved or curled (31) as shown in FIGS. 2 and 3. At the same time, a raised surface part (4) is formed in the center part, a boss and a mounting hole (51) are provided in the center part, and the boss (61) is swaged into the mounting hole and firmly attached.

他に宮障を来たしたものである。The present invention relates to the improvement of the single disk plate that serves as the base for attaching the blades of the conventional centrifugal turbofan as described above. It was simply a disk-shaped plate punched out from a flat plate. As a result, deformations such as distortions are often produced, and not only does it take time to correct them, but it is not suitable for mass production, and uniformity cannot be obtained, resulting in increased costs and other problems in production. This is what I did.

だ理想的なターボファンが得られる。In view of these circumstances, the present invention has improved the quality of the disk (1), which is the basis of a turbo fan, and the peripheral edge of the disk fa+curves (see Figure 2) or curls (see Figure 3). )¥
At the same time, a raised surface part' (41) is formed in the center, so it can be placed on a strong plate for physical reinforcement, regardless of the thin plate.
Since the wing pieces to be planted on it can be attached stably and firmly, the disc will not undergo any distortion or deformation during use as a product, and it can also be used as a product, without causing distortion or other deformation to the disc during use. This eliminates the need for an ideal turbo fan that is highly economical, uniform, and mass-producible.

したこと全特徴とするターボファン。In a centrifugal turbo fan constructed by installing blades radially on a single disc, the peripheral edge of the disc is slightly bent and curved or curled, and a circular ridge is formed in the center. A boss mounting hole is formed in the raised surface, wing pieces are planted in a substantially free shape between the peripheral edge and the central raised part of the disk, and a boss is caulked or otherwise formed in the boss mounting hole. The installation is made up of all the features of a turbo fan.
