Abstract

PURPOSE:To obtain a firm turbo fan by setting a reinforcing metal plate of a certain size either from the top face or bottom face to a main blade centering around the center boss of said main blade and bonding said metal plate to said main blade. CONSTITUTION:Vanes 3 are installed in between a main blade 1 and a sub-blade 2 the center part of which is opened, using a thin metal plate such as aluminum, etc. A reinforcing metal plate 4 of a certain size is bonded to the top face on the center part of the main blade 1 by means of caulking or other methods, on which a boss 4 is firmly installed. Thereby, the part surrounding the boss 5 of the main blade 1 can be reinforced, to obtain a firm fan without developing distortion.

In addition, the boss, which is part of the TI4 structure of the turbo fan, or the entire fan is integrally constructed of hard synthetic wood J1m or ceramic, making it an ideal turbo that is both light and strong, and especially does not cause strain on the main plate during rotation. It's a great deal for fans.

Release the grudge (3)! In order to install the Turbo Un, which is constructed in the form of A boss (5) is firmly attached to the top. (See Figure 4) The reinforcement plate (4) may be the lower surface of the main plate (1).

ート。The present invention has a sufficient effect of reducing the weight of conventional turbofans using thin plates made of approved metal such as aluminum as described above, but the present invention is effective in reducing strain on the main plate especially when rotating at high speeds. Due to its shortcomings, such as poor performance, it was not able to gain a satisfactory fan base. In order to eliminate this drawback, the present invention focuses on the necessity of reinforcing the area around the boss (5) of the king plate (1), and as a result of research, it has been found that Reinforcement of specified size 4 &
This is f/++ reinforced by bonding. Further, as a result of trial driving, it was found that using a reinforcing plate (4) made of hard synthetic resin or ceramic instead of metal or other strong material is quite effective in terms of light weight and strength. Therefore, as shown in Figure 5, the main plate and sub-plate are made entirely of ceramic.
